4 Key Factors to Consider for a Successful A/C Installation

Posted on: April 26, 2015

Was your current air conditioner installed correctly? That may seem like an odd question. The A/C is running, so it must have been installed correctly. That may or may not be true. A successful A/C installation involves more than just getting the equipment to work. Here are four factors that should be considered in a successful air conditioner installation.

The A/C system must be properly sized for your home. A quality installation starts with the HVAC contractor using the ACCA’s Manual J to perform a calculation on how large a system you will need. Manual J calculations take into consideration the size of your home and its configuration to determine the size system you need. If the A/C is too large, it will cycle on and off quickly, which will prevent the system from dehumidifying the air. If the system is too small, it will run constantly driving up your energy costs.

Ductwork Efficiency

Old ductwork can leak 20 percent or more of your cool air into the attic or crawlspace. Addressing the ductwork is essential for a quality air conditioning installation. One option is to replace it completely. The other is to make any repairs necessary, seal the entire system, and insulate it.

Balanced Airflow

The A/C needs to move a certain amount of air to keep your home cool. The A/C manufacturer specifies appropriate airflow rates for particular situations. In a quality installation, the HVAC contractor will adjust the airflow according to those specifications and verify that it is working properly.

Refrigerant Charge

The manufacturer also specifies how much refrigerant the system needs to run efficiently. The HVAC contractor should check the refrigerant levels before turning the system on for the first time. If the refrigerant level is too low, the system will not cool properly and it will drive up your energy costs.

If you suspect that your A/C installation was not done correctly, or need to get a new A/C, call in HVAC professionals. Check out the Air Experts’ air conditioning solutions or call 919-887-2132.
