"ECC is AWESOME!! From talking with Lisa, who scheduled EVERYTHING!! to Ed the gentleman who came out and estimated the job, to Tony, his son and Jane (the installers) everything was seamless!! The communication was EXCELLENT!! Lisa is excellent at keeping me informed about the process and following up when things were done. I can’t say enough about Tony and his crew!! He went above and beyond my expectations! He even RE-routed a condensation pipe to the gutter so it wouldn’t keep dripping onto my shingles!! Just an amazing company!! Would ( and have) recommend them to everyone I know for their HVAC needs"

"This company is excellent. On Monday my oil furnace broke down and by Wednesday, I have a new heater and it was also converted to gas instead of oil. The two technicians, Josh and Justin were so efficient and very knowledgeable. What a pleasure to do business with a company that knows how to satify its customers. I will definetely refer this company for any HVAC services. Thank you"

"Jeff is very professional and competent. He fixed an AC unit the others said they could not fix. I highly recommend him and Mechanical Monster! UPDATE 6/8/20 I have been in my home for 22 years and this is the best HVAC service provider we have ever had! They are very professional, timely, and provide excellent customer service. I highly recommend them."

"Adam and Nate were very prompt, polite and thorough. They replaced the two hvac systems at my home. They worked quietly and cleaned up after themselves. They provided me the best bid with the lowest cost and the earliest delivery time and they delivered. The job was done on time and on budget. I would definitely use AAC again."

"Had an amazing experience! This was the second time using this company and again I was not disappointed!! The guys showed up on time, were very professional. Explained what they were going to do. Since I had just bought a new house and the vents were so dirty they said they would like to use a disinfectant. It’s very nice to have piece of mind knowing that my air and dryer vents are nice and clean! I would definitely recommend them."

"On the price, I don't, but it was also reasonable. They had also installed a water heater like a year before, reasonable. For sure they're a good service provider, any issues I have with the HVAC or my water system, I'll go to them. They clean up behind themselves; I don't have to do much."

Heating and Air Conditioning FAQs, answered by experts

On average, an AC unit lasts between 10 and 20 years. However, the specific lifespan depends on the type of unit, how often it's used, the local climate, and the quality of maintenance. Central AC units typically last 12 to 17 years, while window units have a shorter lifespan of 8 to 10 years. Portable AC units last about 5 to 10 years, and ductless mini-split systems can last up to 20 years. To extend the life of your AC unit, it's important to perform regular maintenance, such as replacing filters, cleaning coils, and scheduling annual professional tune-ups.

A calculation method that your HVAC contractor will use to ensure your system does what it's supposed to is measuring duct output, or its CFM. The calculation requires knowing the cross-sectional area of the ductwork and determining the air speed past any given point within it.

It depends on the size of the space you’re cooling down. If you’re looking for the most affordable way to cool an entire house over a long period of time, then central air will be more cost-effective. But when it comes to cooling down a couple of rooms or one floor, a window unit may be the cheaper option, with both a lower cost to install and less energy used to run.

Yes, you should turn off your AC if it’s leaking. Turning off the system prevents more condensation from leaking and reduces strain on the unit if a damaged internal component or lack of refrigerant is the cause. While this may temporarily stop the leak, water can continue to drip from a thawing coil even after the system is off. As soon as you notice a leak, turn off the unit and investigate the source or call a professional for an inspection.

On average, replacing an AC compressor costs between $800 and $2,300, but it could cost as much as $2,800. There are a few factors that impact the price of a compressor replacement, including the type and size of the compressor, as well as the type of HVAC system and local labor rates.
