"I contacted McGinley & Sons after searching Angie's List for highly rated HVAC specialists. The owner, William McGinley came down quickly to give us an estimate. We were quoted a reasonable price  and booked an appointment to do the job two weeks later. Bill arrived in a timely manner with two other workers and completeted the job in a few hours. He also submitted on our behalf the warranty registration to Goodman Air Conditioning and Heating. We are very pleased with the job they did and would highly recommend McGinley & Sons."

Heating and Air Conditioning questions, answered by experts

A frozen coil can cause permanent damage to your HVAC system and lead to costly repairs if not fixed. It can cause the unit to overheat and also cause the compressor to fail. It’s vital to turn the unit off if the coil is frozen and address the issue as soon as possible. 

It’s critical to use the right size AC for your space and not go too small or too big. If you purchase an undersized unit, it won’t properly cool your house, and it has to work harder to reach the optimal temperature. This will eventually wear your unit out. An oversized unit can spell trouble because it will turn off and on more frequently, which also wears out your AC unit. An oversized unit also causes humidity in the home.

While both have advantages, a split system is generally cheaper than a ducted one. Because they are less invasive to install, the labor costs are lower, and they can be more energy efficient. But, a ducted system might be worth the investment if you run it more frequently. 

If you know how to identify supply and return ducts, you’ll find that only the supply ducts will have dampers. Although your return ducts can have dampers, it’s not common. If you have one return duct that is pulling in too much air, adding a damper to it can help with overall system performance. However, dampers on return ducts are not a necessary addition for most homes.

A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.
