"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

No, it's not advisable to only replace the outside AC unit connected to your system. AC units are designed to work as a cohesive system, and older units work differently than newer units. Therefore, replacing only one component can lead to incompatibilities that affect the system’s performance. Replacing one component can void your warranty, costing you money for repairs.

Yes, it’s important to turn off your AC sometimes to give it a break and prevent it from freezing up. If your AC runs all the time, your system’s parts will wear down quicker, which may mean that you need to replace it sooner. Plus, using your AC constantly uses more electricity and leads to higher energy bills.

You might notice that your air conditioner isn’t running as effectively as it once did. Specifically, your AC unit could take longer to cool your home, or it might struggle to remove humidity from the air. Higher utility bills and hissing sounds coming out of your AC could also indicate a leak.

The cost to repair an air conditioner averages around $350 to $450, but the price can range from $100 to over $3,000. The final cost depends on the type of air conditioner, the extent of the damage, and the specific parts that need replacement. For example, repairing a window AC unit typically costs between $100 and $250, while central air conditioner repairs can range from $300 to $3,000. A simple fix like replacing a dirty filter might only cost $10 to $50, but a major issue like a broken compressor could cost around $2,000 or more, potentially making it more cost-effective to replace the entire system. Due to the need for specialty tools and handling of refrigerants, repairs more complex than changing a filter are best left to a professional.

Both evaporator coils and condenser coils are recyclable and contain valuable, sellable metals such as copper and aluminum. Not only is it more earth-friendly to take them to a local metal recycling facility, but you can also trade them in for cash. Also, once the coils are removed from the system, they won’t have any traces of refrigerant, so you won’t have to arrange for recycling Freon or R-410A unless you’re disposing of the entire AC system.
