"I had been unhappy with another firm in Madison that has worked on both our furnace and central air conditioner, so I contacted Clark, based on a recommendation from Dan of Jenko's garage doors, and checking on Angie's list, where Clark was highly rated. They sent a serviceman (I think it was Kevin) last Tuesday, who inspected our system, which had been installed in 1992, and determined it was leaking Freon. He indicated that repair was not a smart option on an old system and recommended a new air conditioner. Andy came came out on Thursday to give us an estimate. I asked if he could have it installed on Friday, as it was very hot and humid and we were having guests over for dinner. He said he could make it work. On Friday his crew (Jeff and his partner) spent about 5 hours removing the old unit and installing the new one. They were completely professional and thorough. By 5:00 the house was cooling down. I highly recommend Clark Heating and Cooling."

"Justin took care to not over sell me. Only what I needed and understood. The install team were tidy, efficient, and educated me about the safety approaches when changing the humidifier filter. That filter and the furnace filter are the same that was used on my old system. They were professional and personable."

Heating and Air Conditioning questions, answered by experts

When your HVAC system is loud, a few different causes are possible. If you have loose connections or bolts in the hardware, they can rattle as the system runs and vibrates. If you have an extremely dirty furnace filter, it could cause the system to generate noise. More commonly, an excessively loud HVAC system indicates a malfunction in the system. You may have a blower motor that is close to failing or a compressor that is breaking down. These issues require an immediate inspection.

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.

Signs of a damaged evaporator coil include warm air from vents, frequent starts and stops without proper cooling, failure to turn on, refrigerant leaks, and unusual noises. If you suspect issues with your AC system or its components, it’s best to call an AC repair technician for proper diagnosis and repairs.

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.

The average cost to replace or install a new HVAC system is around $7,500. However, the price can range from $5,000 to $12,500, depending on factors like the size of your home, the type and brand of the unit, and your specific heating and cooling needs. If you only need to replace certain components, the cost will be lower; for example, a new AC unit can cost between $2,200 and $5,500, while a new furnace costs $3,200 to $6,000. If additional work like new ductwork is required, the total cost could be as high as $22,000. It's best to contact a local HVAC company for an accurate quote.
