It’s all about the install….
Having your Air Conditioning and Heating system installed properly will ensure that it will perform at optimal efficiency.
In fact, a system that is improperly installed could reduce a central air conditioning unit’s efficiency by as much as 50%.
What you should know about quality installation:
- Do not let anyone convince you that it is ok to replace either the indoor or the outdoor unit without replacing the other.
Almost all new high efficiency central air conditioners and heat pumps require a matched system (indoor and outdoor units) to work properly. The outdoor compressor and the indoor coil work as a team and if they are mismatched it could shorten the life of both units, prevent the system from operating at optimal efficiency, and potentially void the manufacturer’s warranty.
- The only way to accurately choose the size of HVAC equipment appropriate for your house is by having a professional HVAC contractor perform a mathematical calculation that takes into account such details as how many ducts you have in your home and square footage.
This is crucial because although you want enough power to cool/heat your home, bigger HVAC equipment is not necessarily better. And oversized system will cycle on and off too often, which can result in inconsistent temperatures in the home and higher energy bills at the end of the month. Also, because the system turns off more quickly that it should, humidity is not properly removed from the home and as you probably know, on hot summer days, it’s not pleasant to feel damp air in your home.
- Don’t be embarrassed, if your ducts are leaking! A recent department of energy study states: “typical duct systems lose 25-40% of the energy put out by the central furnace, heat pump, or air conditioner.”
This almost certainly means that your air conditioning equipment is working over time to compensate for the air loss. As far as comfort is concerned, improper ductwork is also a major cause of hot and cold spots and can propagate indoor air problems such as dust and mold. Insist that your contractor inspect your ductwork to ensure there are no design errors or kinks in flexible ductwork, the ductwork has proper insulation (R-8 insulation is top of the line for ducts), and that all the ducts and duct connectors are properly sealed with mastic and/or tape. The department of energy says: “duct repairs could be the most important energy improvement measure you can do.”
- Insist that your contractor use properly calibrated instrumentation to determine if your system is properly charged with refrigerant.
Remember that there is a gaseous refrigerant that runs though your system, from the outdoor compressor-baring unit to the indoor air “coil” that circulates the air through the ductwork. If there is too much (or not enough) refrigerant, then the system will not optimally exchange heat between your home and outside – your system will under perform and the life of your system could be dramatically reduced.
- Nearly half of all heating and cooling equipment in U.S. homes never perform to their advertised capacity and efficiency levels due to improper installation.
This costs homeowners more in utility bills and can even shorten the equipment’s life. A quality installation of energy-efficient equipment ensures you’re getting the best performance from your Air Conditioner and saving money too.
A quality installation of your central air conditioning equipment can help keep your home comfortably cool in the summer while saving you as much as 36% on annual cooling costs.
