"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

If you’re looking for a portable, budget-friendly cooling solution that doesn’t require any venting or installation, a ventless AC system is a good option. Similarly, this is a great choice if you’re renting an apartment or home and aren’t allowed to make large, structural changes like installing comprehensive HVAC, or you’re in a shared space and only need to cool your own room.

AC capacitors have a wide lifespan, ranging from five to 20 years, with an average of about 10 years. Many capacitors will last for the entire life of the air conditioning unit, and most homeowners only need to replace one once. A capacitor should only be replaced if an HVAC professional diagnoses a problem with it. Premature failure can be caused by overheating, power surges, or short circuits. You can help extend the life of your AC capacitor by scheduling regular AC maintenance each year.

Yes, you can potentially save $60 to $200 by handling your own air conditioner capacitor installation. However, capacitor replacement comes with the risk of electric shock. Only attempt this if you have the knowledge and protective gear to carry it out safely. Otherwise, we recommend hiring an HVAC pro with the experience to properly diagnose the issue and avoid damaging other parts of your AC unit.

Dirty filters are almost always the cause of poor airflow, so they should be regularly cleaned and then replaced as needed. The fan blades can also get dirty, so they should be cleaned when the unit is turned off. Make sure that the outdoor area around the back of the unit is unobstructed. Trees, shrubs, trash, and other objects could be too close to your unit.

Yes. It's not just AC filters that get dirty. Ducts can accumulate dust and dirt quickly. Insects and animals can also get into duct systems, creating many problems. Dirt build-up and unwanted guests can constrict the airflow and cause rooms not to cool evenly. You might also see higher energy bills because they're not working as efficiently.
