Siting Residential Heat Pumps: Installation Tips For The DIY Mind

Posted by on 4:02 pm in Uncategorized | Comments Off on Siting Residential Heat Pumps: Installation Tips For The DIY Mind

Proper installation of heat pumps is important for DIY-minded homeowners who may wish to enjoy the benefits of using a heat pump. DIY installation of heat pumps may be relatively easy but the slightest of mistakes can have a negative impact on pump performance. Choosing the right location is vital for the performance of a heat pump and for compliance with regulations formulated to control noise pollution from household appliances. With this in mind, here are three tips on choosing the right location for heat pump installation. Isolation And Elevation Of Heat Pumps The ideal location of installation should be isolated from residential building structures so that there’s minimal transmission of vibrations and sound to adjacent structures whenever the pump is operational. If the situation demands for a heat pump to be attached to an external wall, the pump shouldn’t be installed on the external wall of a study room (or bedroom) where noise from an operating pump will be more of a nuisance. In order to reduce vibrations on an operating heat pump, DIY-minded homeowners are advised to install heat pumps on solid and level mounting pads. These mounting pads are often made of concrete or plastic, with the latter often being more affordable than the former. In areas that experience heavy snowfall, heat pumps should be installed on a mounting pad that elevates the pump high above the average snow line in the area. This helps to prevent direct contact between the pump and snow that accumulates on the ground. Access To The Pump While at it, DIY-minded homeowners should also ensure that their preferred location of installation allows for easy access to the heat pump. The importance of this is often seen when it is time to do maintenance on the pump. For example, it is often not a good idea to install the heat pump in the often narrow “alley” between two adjacent structures on the residential premises (e.g. a narrow space between one wall of the house and a garage shed). Air Circulation Last but not least, heat pumps should be installed in an outdoor area that allows for maximum air intake. This is because the pump needs a constant supply of air to extract heat from and then move it into the house. Dense vegetation around a heat pump can break the continuous supply of air to the pump. As such, DIY-minded homeowners should install their heat pumps away from areas that have a thick vegetative...

4 Top Benefits of Split HVAC Systems

Posted by on 11:48 am in Uncategorized | Comments Off on 4 Top Benefits of Split HVAC Systems

There are two main types of HVAC systems for the home: duct and ductless. Ducted air conditioning units are the most common, but there is a growing trend in split system air conditioners. They offer numerous benefits, and here are four that you should be aware of when you come to choosing a system for your home. They Save Money People are always looking for ways to save money on their spills and a split HVAC system is a way to do that. According to Energy.gov, 30% or more of energy consumption is accounted to losses through ducts because they are not insulated properly. Without the ducts to worry about, you instantly benefit financially. The systems also deliver the cooler air more precisely into the rooms that actually need it. It is possible to cool some rooms during the day and others only during the night. This reduces the amount of energy the systems use, saving you money. Easy to Maintain and Use Split system air conditioners are much easier to maintain than their ducted counterparts. While you will need to clean the filters, you don’t need to get within the systems to check for duct leaks or full cleaning. The systems are designed to need periodic cleans and the filters are washable. These systems are also very easy to use. You control everything through a thermostat and remote control. The thermostat sets your room temperature and you can control the zoning from your armchair. Better Air Quality Window units are often linked to poor indoor air quality. They may not work properly and can sometimes pull pollutants in. Likewise, fault ducts can lead to pollutants and dust spreading around the home. Regular cleaning and professional maintenance is also required to make sure the air quality remains high. Split HVAC systems don’t have this issue. The pollutants are pulled out and the home is left allergen free. The systems have a multi-stage filtration system to ensure all allergens are not circulated into rooms. Attractive Units It is much easier to hide a ductless system than the clunky duct ones. You will have an outdoor unit and then individual indoor ones for various rooms in your home. They can be placed on walls, flooring and ceilings to work with the style of your home. Spilt system air conditioners are much friendlier for your home. They are cost effective and easy to use and maintain. It is time to consider one for your...

2 Simple Cleaning Jobs That Can Keep Your Home’s Air Conditioner in Tiptop Shape

Posted by on 9:17 am in Uncategorized | Comments Off on 2 Simple Cleaning Jobs That Can Keep Your Home’s Air Conditioner in Tiptop Shape

If you hate the idea of facing another air conditioner repair bill, you might want to think about how you maintain the system in order to reduce wear and tear on the motor, fan, and other parts of the air conditioner. Typically a few minutes of maintenance or cleaning can ensure that your home’s air conditioner is always in tiptop shape, and that you’re doing everything possible to lighten its load overall. Note two of those cleaning jobs you can manage on your own. 1. Clean the ductwork and vents  When was the last time you had your home’s ductwork and vents cleaned? If you can’t readily remember, it’s time to get it done. Ductwork can collect dust, lint, rodent droppings, dead bugs, and much more. Take a look at the vents in your home and note if they’re coated with dust, hair, and the like. If so, the air conditioner then needs to work harder to push that flow of air through those ducts and your home’s vents, as all that debris slows down that flow of air. To help your air conditioner work easily, have ducts cleaned every year or as often as you think is necessary. If you can’t afford to have them cleaned professionally, remove the vents and use a vacuum hose as far as you can reach inside the ductwork to remove as much dirt and debris as you can. 2. Clean the evaporator The housing unit that sits outside your home is not the only part of your central air conditioner; the unit has an evaporator which removes heat from an area to be cooled. The evaporator usually sits on top of your furnace, inside the home. This evaporator is typically protected by what is called a plenum, or large metal hood that looks like ductwork. You may note this part on the top of your furnace. You can access the air conditioner evaporator by unscrewing the front panel of this plenum. The evaporator will usually be in a triangle shape, with coils that face you. If dust and debris are allowed to build up on these coils, the evaporator doesn’t work as efficiently to remove heat from the home and the air conditioner needs to work harder. Clean these coil with a soft but stiff brush that is meant for cleaning appliances. Run the brush around the coils and under the evaporator, but avoid using too much force or using a vacuum cleaner brush on this piece as it can be delicate and you don’t want to break any coils. Once finished, return the front panel of the...

Causes of Cold and Hot Spots When an HVAC System Has Been Installed

Posted by on 8:37 am in Uncategorized | Comments Off on Causes of Cold and Hot Spots When an HVAC System Has Been Installed

You may be wondering why there are cold and hot spots in some sections of your house after you have installed an HVAC system. Read on and discover some of the common causes of what you are experiencing.  A Poorly Sized Unit An HVAC system that is too large for your home will cycle on and off quickly. That short run time means that the air within your home will not move over the evaporator coil several times so that it is sufficiently cooled or heated. This means that the peripheral sections of your home (such as the corners of the rooms furthest from the AC ducts) will be warmer or colder than the rest of the room. The remedy to this problem is very costly because you have to buy a new HVAC system or have the one you bought exchanged for the correct size for your home. Leaks in the System The points at which duct sections are joined may leak if they were not sealed appropriately with the recommended products (such as aluminum tape or sealing mastic). Conditioned air may leak from those joints and reduce how effectively different sections of your home are heated or cooled. You can inspect the system and be on the lookout for abnormal levels of condensation on segments of the ducts that are close to duct joints. Seal all the joints that show signs of leaking with the recommended sealing products. Lack of Insulation Cold and hot spots may also be the result of ducts running through parts of the home that do not receive conditioned air (such as the attic). Conditioned air may be heated or cooled due to the ambient temperature in those unconditioned spaces. Consequently, the air delivered by these affected ducts will be cooler or hotter than when it left the AC unit. Cold and hot spots will result. This problem can be fixed by insulating all the ducts running through unconditioned spaces so that this heat and energy loss avenue is plugged. It may not be very easy for a layperson to identify the exact reason why his or her home has cold and hot spots. Tampering with the HVAC system may also void the warranty since many manufacturers insist that only certified technicians should repair AC systems. It is, therefore, advisable for you to hire an HVAC professional to check your newly installed air conditioning system thoroughly so that appropriate remedies can be implemented for the cause of those cold and hot...

The Risks of an Oversized Commercial Air Conditioning System

Posted by on 3:14 pm in Uncategorized | Comments Off on The Risks of an Oversized Commercial Air Conditioning System

One of the most challenging steps before the installation of a commercial air conditioning system is to determine the correct size of the unit that you should buy. Some owners of commercial buildings do not consult HVAC professionals before making a purchase, so they may end up with a unit that is too large for the requirements of that commercial building. This article discusses some of the risks that you are likely to face if you install an oversized AC system. Humidity Issues Air conditioning systems do two things simultaneously; they cool or heat the building and remove humidity. An oversized system will cool the room quickly and stop working. This will give the evaporator coil a limited chance to remove moisture from the indoor air. Properly sized AC systems run for a relatively long time before cycling on and off. This prolonged run time moves the indoor air over the evaporator coil for a longer time resulting in effective humidity control. Thus, an oversized system will create ideal conditions for the growth of mould since the building will always have high levels of humidity. Short Component Life AC system components such as the compressor will break down frequently. This wear will be the direct result of very frequent stop/start cycles (described earlier) that overwork the moving parts of the compressor. Thus, you will incur higher AC repair costs if you made the mistake of installing a unit that is larger than what was required in your commercial building. Energy Waste An oversized AC also hurts your earnings on a monthly basis. The short start/stop cycles also have an impact on the energy consumed by the system. The compressor uses a lot of energy to start. It therefore follows that much more energy will be consumed by the AC system if the start/stop cycle is short. That extra money spent on energy is money that should be remaining in your pocket. Noise Air conditioning systems emit varying levels of noise as they operate. A larger unit will generate more noise when compared to the noise level that would have been generated by a smaller unit. This may compel you to incur additional costs to provide noise attenuation systems so that the tenants of your commercial building do not complain that the noise is affecting their commercial activities. Think like an astute businessperson. Hire a professional to assess your AC needs correctly so that you install a commercial air conditioning system that will not expose you to the risks...

Establishing The Reputability Of An HVAC Service Contractor

Posted by on 8:52 am in Uncategorized | Comments Off on Establishing The Reputability Of An HVAC Service Contractor

The convenience associated with the use of residential air conditioning units is often invaluable. In order to enjoy this convenience, homeowners must ensure that residential air conditioning systems are installed correctly and regular maintenance of these systems is observed. That having been said, it is important that the installation of air condition units and subsequent maintenance-related activities are handled by a reputable HVAC service company. This article provides three qualities that homeowners should look for in a HVAC service specialist or company.   Membership With Professional HVAC Associations Membership (or lack thereof) with professional associations can be used to gauge the reputability of air condition service specialists.  In order to acquire registration with professional HVAC associations, air conditioning specialists need to prove their compliance with state and local by-laws that are relevant to the HVAC industry. As such, a registered air conditioning specialist is sure to undertake the installation and/ or maintenance of residential air conditioning systems in accordance with the requirements spelt out by state and local by-laws. Prospective clients should not be afraid to ask for physical evidence of membership with professional HVAC associations from their preferred specialist. Participation In Continuous Education/ Professional Development Programs Participation in continuous education programs for HVAC specialists is also a sign of reputability. Considering the ever-changing nature of work practices in the HVAC industry, continuous education and professional development training programs are essential for air conditioning specialists who intend to remain relevant in the provision of services related to the installation and maintenance of residential air conditioning systems. Staffing In a large number of cases, HVAC specialists are forced to hire additional labour due to the often labour-intensive nature of HVAC-related works. Contractors can either hire independent sub-contractors, or they can have permanently employed staff for the additional labour . Homeowners are often advised to settle for HVAC contractors who have permanently employed staff members instead of contractors who work with independent sub-contractors. Employed members of staff have more to lose in terms of their career prospects in the event that they provide sub-standard services. As such, they’re bound to pay greater attention to detail when undertaking installation and/ or maintenance related activities on residential air conditioners. However, this should not be taken to imply that independent air conditioning service providers are unprofessional. Homeowners looking to protect the investment that residential air conditioning systems are cannot afford to compromise on the reputability of HVAC contractors trusted with the handling of these systems. Using the tips above, you can find experienced air conditioning specialists in your area to take care of the work you need...

Options for Commercial Air Conditioning from HVAC contractors

Posted by on 1:11 pm in Uncategorized | Comments Off on Options for Commercial Air Conditioning from HVAC contractors

Although most people are familiar with residential air conditioning systems, not many are abreast with what is available for commercial use. It should be noted that the designs as well as the components of commercial air conditioning systems vary quite a bit from their residential counterparts. This is because each system is designed for different applications, especially when it comes to the different requirements for commercial use. Buildings such as warehouses, factories, manufacturing plants and office blocks will each have their own air conditioning needs, which are not the same. This is why it is important to know some of the different types of commercial air conditioning units that are available to you from HVAC contractors like Nilsair Pty Ltd. The radiant and forced air commercial air conditioning units. These systems include two general methods of regulating the temperature of a given space. A traditional radiator is what would be most familiar with the radiant commercial air conditioning systems. This is because the radiant systems will transfer both hot temperatures as well as cool temperatures by making use of a series of pipes that carry either hot water or cold water. These pipes tend to be concealed under floors or hidden behind walls. Forced air systems will make use of ductwork as well as fans to achieve the circulation of air in and around a building. Once the air has been sucked out of a building, the furnace coils will condition the air so as to change its temperature and then transfer it back to the ductwork system. Single and multiple zone commercial air conditioning systems The phrases single and multiple zones refer to the amount of control, as well as the method that will be used, by a commercial air conditioning system. A single zone system will have one control panel. This is what will be used to regulate temperatures across an entire floor or several rooms on the same floor simultaneously. On the other hand, the multiple zone systems will have several controls that will regulate the temperatures of several areas such as different floors or various rooms. A single zone commercial air conditioning system requires little equipment to set up and thus tends to be an affordable option for smaller businesses. However, multiple zone systems tend to be much more popular as it allows people to regulate the temperatures of various rooms in the building without affecting each other or various other...

What to do if your air conditioner is working but is not spreading cool air

Posted by on 1:23 pm in Uncategorized | Comments Off on What to do if your air conditioner is working but is not spreading cool air

An air conditioner is very important as it keeps the temperature in your home at a comfortable level. To be able to do this, it requires a lot of energy, so it’s important to make sure that it does the amount of work that makes up for the energy being spent. If your air conditioner is working at full speed, but still doesn’t seem to be spreading cool air very well, there are some things you can do about it. Filter Even if you are a novice at handling electrical equipment, there are still some air conditioning repairs you can perform on your own. The very least you can do is to troubleshoot it on your own. The first thing you need to make sure of is that the filter is clean and whole. Remember to turn off the power to the unit before you open it and take a look at the filter. Sometimes it’s enough to just clean off dust and dirt, but sometimes you might need to replace it entirely. You should be changing your filter regularly anyway, even if the unit is not malfunctioning, to get the most out of your air conditioner. Condensate drain Examine the condensate drain. As air conditioners remove moisture from the air, they can produce quite a lot of water that goes through this pipe. Mould or algae might have formed in the pipe and blocked it partially. This would cause the air conditioner to not operate properly even if it’s technically working. This could also cause puddles of water around the condensate drain. Compressor Another piece in you air conditioner that might cause it to malfunction is the compressor. If you put the thermostat to a temperature below the temperature of the room, you should see the fan start spinning. If the fan doesn’t spin, you could investigate this by using a long, thin tool and try to reach the fan through the grille. If you can’t make it turn, it’s possible some sort of dirt has gotten into it and is blocking it. If it does turn, then the problem is electrical and you should contact a professional. Malfunctioning thermostat The problem could also be in your thermostat. It might be failing with sending the proper signals through the cables and thus causing your air conditioner to malfunction. These types of errors are difficult to troubleshoot on your own, and you should contact an air conditioning repair service that can help you out with either replacing the thermostat or getting you a new air...

Tips for Choosing Air Conditioning Systems for the Home

Posted by on 11:16 am in Uncategorized | Comments Off on Tips for Choosing Air Conditioning Systems for the Home

When selecting a new air conditioning system for the home, you want to ensure you invest in a quality unit that will work for your space. Many homeowners make the mistake of choosing the cheapest air conditioner they can find, only to see that it doesn’t work very well in cooling. They may also make a mistake in the opposite direction and choose the largest, most powerful unit they can afford, only to find that this too doesn’t work well for their home. Note a few tips for choosing air conditioning systems and how to determine the right choice for your home. 1. Selecting size Many homeowners make the mistake of thinking that a larger air conditioning unit is always going to be better, assuming that it will cool a space more quickly and efficiently. In truth, an air conditioner that is too large and powerful for your space will be very inefficient and even ineffective.  This is because an air conditioner is meant to cool the air but also to remove humidity from the space. A large unit may cool the room to a certain temperature but it may do this so quickly that it does not have time to remove humidity. Your space then feels cold and clammy, not comfortable. When choosing a size for an air conditioner, choose the recommended BTUs for the square metres of the room using recommended charts on the unit or that you find online, and only increase the BTUs by a small percentage for very warm rooms such as a kitchen or sunroom. 2. Ease of maintenance and use No matter the type of air conditioner you choose, it should be easy to maintain. Note where the filter is located and if it can slide out conveniently for quick changing. For a central unit, note if the front panel is easy to open so that you can remove any debris or perform quick repairs and cleaning on your own.  For a window unit, consider if it has an accordion fold that fits into your window and if this fold is weather-tight so you don’t need to remove the unit every winter. For a portable unit, choose one with solid casters and a handle that folds out and back into the unit so you can move it around easily, rather than having to drag it across the floor every time you move it from room to room. Keep these tips in mind and talk to professional HVAC contractors, like those at Tozer Air Conditioning, for more...

5 Tips to Keep Cool this Summer

Posted by on 6:45 am in Uncategorized | Comments Off on 5 Tips to Keep Cool this Summer

For many people summer goes hand-in-hand with an overly inflated energy bill, caused by a constantly running air conditioner. If you’d like to spare your wallet from the damage caused by running your air-conditioning system non-stop, follow these tips to keep cool and save that AC for when you really need it: Wear Cotton (and nothing but Cotton) Cotton is an amazing material – it’s completely natural, it’s comfortable, and it keeps you cool in summer! Cotton’s natural structure allows a lot of air circulation around your body, which helps minimise sweating. This has the benefit of not only keeping you cool and dry, but also greatly diminishing the potential for a fungal infection to form on any part of your body (as fungi thrive in moist environments). Cool your Sheets Here’s a handy trick – before you go to bed, stick your bed sheets in the freezer for a few minutes. If you’re going to bed hot, the crisp and cold sheets will give you some much needed relief and lower your body temperature to a comfortable point. Additionally, you can easily do this with clothes. Refrigerate a shirt for a few minutes, and put it on right before you go out. It’ll make the heat much more tolerable (at least for a few minutes). Watch Out for Coffee and Alcohol There’s no need to abstain completely, but try not to go overboard with coffee and alcohol. Both of these substances cause dehydration, and dehydration is definitely not a state you want to be in during the blistering heat. Cold Showers There are few things as refreshing as a cold shower when the heat gets particularly intense. Having a cold shower before bed is great – you rinse off all of the day’s sweat and stickiness, you cool down, and you go to bed feeling fresh and clean! Spend the Day Somewhere Cool Summer comes with many days off. Unfortunately, if it’s a choice between an exorbitant AC bill and suffering in the heat, the day off can seem much less exciting. If it’s too hot, go out for the day. While at first you may not feel like leaving the house, there are plenty of wonderful public places that are always cool; shopping malls, libraries, movie theatres – fill your day with fun activities that take place somewhere where they are generous with the AC. Contact a company that deals in heating and air conditioning repairs to learn...
