Homeowner Tips: Benefits of HVAC Matched Systems
Owning a home requires a lot of learning as you go, including understanding why HVAC matched systems are a good idea.
A home’s heating and cooling system is probably one of the most hard-working appliances. Your HVAC system, which stands for heating, ventilation and air conditioning system, never gets a day off.
On Texas’ Gulf Coast in Richmond, Texas and the Greater Houston area, our winters are usually mild. The rest of the year is warm to hot with plenty of humidity. In a nutshell, we use our air conditioner a lot more than we use the heater.
Why Is Your Heating and Cooling System Called a Split System?
Split systems refer to the fact that residential HVAC systems have an indoor and an outdoor unit. The indoor unit, usually located in the attic or a hall closet, houses the blower unit and evaporator coil. The outdoor unit, on the other hand, is also called the condenser. Condensers are often located on the side of a home outdoors.
A mini-split works the same way, it’s just smaller. And, it is usually designed to heat and cool a smaller space.
Why Does a Heating and Cooling System Need to Match?
No reputable HVAC contractor is going to recommend installing an indoor and outdoor unit unless it matches. Manufacturers design indoor and outdoor HVAC systems to work together. Matching systems will work better together, be more efficient, cost less money to run, and last longer. Manufacturers can void warranties if unmatched HVAC systems are installed.
Indoor and outdoor units need to match in the following ways:
- Output – How much heat or cooling does your space require?
- Refrigerant – Split systems work together, so the refrigerant must be the same.
- Size – There are often choices about the size to fit your space requirements.
In the past, many HVAC system components could be mixed and matched. However, as technology has progressed and environmental regulations have gotten stricter, mixing and matching equipment is no longer possible. Mismatched heating and cooling systems are less efficient, and new regulations mean there are steep federal and Texas penalties to HVAC contractors for installing them.
