"Extreme Heating and Air Conditioning installed an 18 SEER HVAC system with zone control for me. I am very pleased with the results and performance of the system - far better than the previous system WRT air flow balance. All personnel were very knowledgeable and professional and I highly recommend this company. Thanks to Tristan, Brett, Ryan, Joe, Paul and special thanks to Dave and Tyler for working through some parts failures. I am very pleased."

"Pretty good experience if you just install new HVAC. But, if it is full HVAC and duck replacement, you will need to ask during quote. Otherwise, you will have trouble."

"This company is fantastic. I had a mess in a home we bought to rehab. These folks cleaned the ducts, but saved me $4,000+ dollars on various things they found that were serious issues, that were not related to the ducts. Even found a place where a previous installer for my water heater set me up for a fire. These folks are fantastic. $700 cleaning, $3300 saved!!!!"

Heating and Air Conditioning questions, answered by experts

For washable or electrostatic air conditioner filters, you can soak and rinse them with water. If you rinse the filter with water, make sure to use a faucet, shower head, or garden hose with a gentle water pressure setting, as strong water pressure could damage the filter.

But for disposable filters, water could ruin the filter, even allowing mold to grow in the filter. Instead, these filters should be replaced.

If you don't clean your AC evaporator coils, dirt and debris will build up, which impairs the system's ability to transfer heat. This forces the unit to work harder, leading to inefficient performance, higher energy bills, and frequent breakdowns. Over time, neglected coils can corrode, which may cause refrigerant leaks, or develop mold, ice buildup, and a clogged condensate drain, resulting in poor air quality and an uncomfortable home.

A 3-ton AC unit is probably too big for a home that’s 1,200 square feet. If you have a 1,200-square-foot home, you likely need a unit that’s somewhere around 1.9 and 2 tons. An AC unit that’s too large will be really inefficient and cost you a lot of extra money on your bills. 

Air filters with a high MERV rating, 11 or above, shouldn't cause airflow problems in most residential systems. However, the airflow can be restricted in some HVAC systems if they aren't designed for high MERV ratings. If in doubt, a local duct installer should inspect your ductwork so that you know what your system can handle.

The decision to put your AC unit on the roof or ground depends on the climate in your area, the roof shape, accessibility, and budget. If you live in a warm climate or don’t have existing ductwork, it’s likely best to stick to a traditional AC unit that sits on the ground. However, if you lack yard space, live in a mild climate, and have easy access to the roof, your home may benefit from a rooftop AC unit.
