Buying a new HVAC system can be one of the largest purchases you can make for your household or business. When deciding what to buy it is recommended you do a comparison of products so you make the best choice suitable for your needs.
The most common HVAC system is a split system. This is the traditional system found in the majority of houses. It consists of inside and outside components. There will be a refrigerant cooling air conditioner, an evaporator coil and a furnace and fanto circulate air and convert refrigerant. Air will be carried through your home or business via ducts, and there is a thermostat or control panel that allows you to set your desired temperature.
For improved efficiency you can consider a hybrid HVAC split system. This type of model gives you an option of having an electrically fueled heat pump different from the traditional gas furnace. It can save you money on your power bill. This system will have a heat pump that cools or heats the refrigerant, an evaporator coil and a furnace to circulate the air and work with the refrigerant, and ducts to move the air around.
If you determine you have numerous areas where ducts can’t go by using a traditional system. You can go duct free! A duct free system will have an air conditioner or heat pump to cool and heat the refrigerant, a compact fan coil, tubing for the refrigerant and wires connecting the fan coil to the unit outside, and a normal thermostat or control panel.
If your home or office is too small for one of the previously mentioned systems, you can purchase a packaged heating and air conditioning system. It basically comes without all the separate components. For example, the heat pump/air conditioner is in one unit with the fan coil/evaporator.
No matter what your needs are, there is a system that will work well for you. Read reviews and do a comparison to help you make up your mind. Remember, a certified technician can help you choose what system is best for your situation.
Realistically there are hundreds of reasons a HVAC system may be experiencing some issues. However, you can narrow them down to some common factors. Here are some of the main reasons for a non-working HVAC system.
It may sound obvious, but check the breaker box! A blown fuse is a simple fix and a common problem.
Check and see if there is a situation with the outside fan. The outside fan is crucial because it takes the heat from your home to the outside. If it is not working, the heat transfer isn’t occurring.
Bad wiring could be preventing the HVAC system from getting the power it needs and could potentially trip the breaker. It is a fire hazard as well, so look for any wires that appear loose, not connected or simply old.
Freon, or refrigerant can cause issues if the levels are too low or too high. If the levels are low, chances are you have a leak in your AC system and the leak needs to be located and addressed.
A faulty thermostat is another common problem, confirm it is not accidently turned off or on the wrong setting.
The coil could be frozen. This is normally caused by airflow issues, dirty air filters and return air being obstructed somehow. (Changing air filters is one of the most important tasks you can perform to keep your HVAC system running well)
If there is an issue with the coil, the compressor needs to be examined. The compressor is the heart of the AC unit and normally next to the coil.
The capacitor is possibly burnt out. The capacitor is what helps the motor run at a consistentspeed.
Make sure your drain lines are not clogged with debris causing the drain pain to fill up.
Remember, if you have any questions or concerns, it is best to call a trained HVAC technician to your house and have them perform an inspection of your HVAC system.
HVAC systems can be a costly expense for your house or business. First, you have to install one, then you have to maintain it and finally, pay for the power they use every month. It is an expense that is hard to avoid, since maintaining an ambient temperature is important for the well-being and productivity of your family and staff.
When looking at installing a unit, there are a few factors that come into play. What size do you need? If it is too small you won’t have enough power to cool or heat your home or business. If it is too large, then you will be paying for an unnecessary expense. An HVAC technician will be able to suggest if you need a one-ton or even three-ton system.
Part of the installation cost will involve hiring a HVAC contractor who is certified to work with refrigerant from the EPA. Depending on if you have had a central air system before, you may need to install new breakers, wires and duct work. Will you require a new thermostat? Be sure to get a few quotes from different companies to determine if the prices you are being given are fair. Read reviews and get opinions from friends and family on who they recommend. HVAC installation is a big and important job, so educate yourself on who you are trusting to install it in your home or business. A trained professional will be able to answer all your questions pertaining to small, but important issues such as how loud is the system? Does it run quietly? On average, how many years do various systems last for? Is there a warranty? How much do repairs usually cost? What are the most common problems with different models?
Keep in mind as well, that there are occasional rebates and tax breaks given for using Energy Star-rated systems. Find out how much per average the system you are installing will cost you on your monthly power bill, this will help make sure you are not shocked when you receive your first bill! An efficient system will save you money over the long term.
