"My wife and I appreciated the time Wayne took explaining what needed to be done and answered all of our questions prior to and during the installation. He and his crew did an excellent job installing the 2 high efficiency HVAC systems. Both systems are running well. I thank Wayne for his ongoing dialogue during the installation which gave us confidence in the quality of his workmanship. Even though the systems installed were an upgrade the cost was less than all the other installers that gave us price quotes for the project."

"The experience with Caesar and his A&C team was fantastic. Very competitive pricing for replacing my central air system (and the initial quote was also the final price). More importantly the work performed was very thorough - Caesar took his time to do the job the right way. Meticulous clean-up at the end of each day was also much appreciated. Overall great, highly-skilled professional who I would gladly reccomend to friends and family for their HVAC needs."

"First Alfano Mechanical Inc. came to my home, said they would do the job and called the office told them to get me on the schedule ASAP. Gave me a price per hour. Well he never called back to this day. Would not recommend them to no one. Job was to HARD for them. Also I had my AC on my worry free with PSEG and they made me take it off because they would not work on my unit in the tight spot that it was installed in my attic 11 years ago. SO WITH THAT BEING SAID: Celestial Air HVAC called when I first contacted Home Advisor and after not hearing back from Alfano(which I would not have hired because they didn t live up to anything he said while here), I called Celestial(and so glad I did) and they came the next day, said it was a hard job and a mess but nothing they couldn t handle. Anthony and Gus came the next day worked their butts off and I have my central air conditioning working right after 11 years. Great price and did over and above what was told to me in the beginning. I would recommend them to everyone and give them a 5 *****. We are very Happy People now. 👍👍😊😊"

"My heating system wasn’t working properly, so I put the job at Angie’s list and Ray was the first one to call, very professional and he sent his tech (Isiah) right away and was able to remedy the issue in a timely manner. Very happy with the service with Ray’s HVAC and Isiah. Saving their contact details as my HVAC guy from now on."

"Amro came over within the hour and looked at the pipe. I told him that I recently lost my job due to Covid and he worked with me on the price. He completed the job in minimal time and was meticulous about cleaning up after himself. As he was leaving, I asked him a question about my gas fireplace and he took the time to look at it, fix and and make sure it was safe to use. He even made me turn it on and off so he could watch that I was doing it correctly. I can't recommend him enough. He is now my plumber/HVAC guy."

"Mo is honestly a breath of fresh air. The quality of his work is second to none. He is brilliant. He works to find solutions. He does not sell you on anything but, instead, gives you options to make decisions. Mo is a wonderfully kind man. He is trustworthy with excellent communication. He always arrives on time. I could go on and on, but he really is a gem of a find. I highly recommend his company and would use him for anything HVAC related."

Heating and Air Conditioning questions, answered by experts

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.

There are a few things you can do to make your AC repair technician’s job easier and your home more comfortable while you wait for AC repair:

  • Cut back trees, shrubs, and weeds around the outdoor compressor 

  • Clear a pathway inside and outside to your AC components

  • Set up a ladder for attic access if necessary

  • Pull your window AC out of the window and place in an easily accessible spot

  • Supplement with fans and open windows to help keep your house comfortable

It is normal for the attic to be hotter than the rest of the house in the summer, but only by about 10 or 20 degrees. Attics that aren’t properly insulated or ventilated can reach temperatures of 130 degrees or more which can cause damage to the home’s structure, including the roof, wood framing, and HVAC system.

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.

When your HVAC technician mentions recharging your home AC unit, they’re referring to the process of topping off the unit with refrigerant, so the levels are properly maintained and pressurized. Normally, a properly functioning AC unit doesn’t need additional refrigerant, but AC units can develop leaks or other problems that decrease the amount of refrigerant needed.
