"Repairs were excellent and thorough "even well documented". The tech found units low on coolant. He identified and repaired multiple refrigerant leak points. I have dealt with many HVAC contractors over the years and Freedom Air Mechanical is one of the best. I highly recommend."

"We have been a Palmer customer for 6 years. The front office and the technicians has always been great to work with. We have been using their AC and Heating Service Plan and on automatic oil and propane fill for years and we have never had an issue. My most recent experience was today for the AC Service Plan. The technician (David) was very polite, experienced, knowledgeable and respectful of our time and home. It’s always a great experience to have maintenance conducted in you home and have the technicians give you expert advice on your heating and AC system. Our AC system is well over 25 years old and still running strong thanks to Palmer. I continue to be impressed with Palmer and will remain a customer for the foreseeable future!"

"Patrick called Friday night and showed up at 7:15 AM on a Saturday morning (OMG) to repair a central A/C system that was icing up inside. I'm still waiting to hear from the other 2 companies that were listed in my area. I know they will call Monday which would mean myself and my disabled wife would spend a very uncomfortable weekend and probably longer because most HVAC companies don't work weekends and it usually takes at least a day to schedule an appointment. Not fun when the humidity is 65% and the temp is close to 80. Patrick did a great job, A/C is running like new. Will hire him again and recommend him in a heart beat. Prices are very reasonable. Hire him!"

Heating and Air Conditioning questions, answered by experts

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.

To keep a window air conditioner in good working order, you should clean the filter regularly, inspect the seals, and store the unit properly during the off-season.

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.

Yes, the furnace and AC use the same blower. The blower is located in the base of the furnace and pushes hot air out of the furnace and into the ducts. It also pushes cool air through the home when the air conditioning is on. Even though the furnace and air conditioning work independently of one another, the blower is an essential component for both systems.

Fixing a leak in an AC unit costs $200 to $1,600, depending on the type of leak and any related damage. But depending on the age and condition of your AC, it might make more sense to replace the AC unit instead of repairing it. If your AC is only a few years old and relatively problem-free, then repairing it is the right call. But if it’s nearing a decade old and has other issues, consider replacing it.
