"The technician, Mark, came quickly and worked diligently to find the problem and as soon as parts come in will set up an appointment to complete repairs. Was able to temporarily fix my AC so it will operate until parts are available to repair the unit. Great job so far and fair price. Very very satisfied recommend this company . ?"

"I called Steve on a Saturday, and he picked up the call himself, not some answering service. I explained the problem I was having and over the phone explained the issue i may be having. He went out of his way. He then he could come out the next day on a Sunday at 9:00 in the morning to take care of the problem with my furnace. He knew exactly what to test and fixed the problem at a reasonable cost. Even after he left, there was a small issue that still remained, and he told me over the phone how to take care of it, and that issue was taken care of also. I will use him again if ever I need a problem looked into."

"Nathan did a stellar job quickly diagnosing a problem with my heat pump that my old HVAC guy (with about 40 years of experience) couldnâ t figure out in two different service calls. He takes pride in his work, does a great job, and is pleasant to deal with to boot. I can not recommend him enough."

"Juan did an outstanding job and was every bit of professional. We had a fairly complicated TV installment which required moving one TV from our family room up to our third floor and then installing an 85 inch in our family room. Juan took his time, got the right materials, and was very respectful. I will hire him again if the need arises and highly recommend him."

Heating and Air Conditioning FAQs, answered by experts

Capacitors are the most frequent part of an HVAC system to experience failure. These components are crucial for starting the motors that power the fans and compressor, but over time, they may become worn or fail due to electrical surges or regular wear and tear. When capacitors malfunction, HVAC systems may experience decreased heating or cooling efficiency, or even total system failure. Replacement or maintenance of capacitors is a common requirement for the optimal functioning of HVAC systems.

Air conditioners can stop working in the middle of the night for many reasons. Your local power grid might shut down late at night. Power surges can also trip your breakers if too much power is being used in the area at the time. If your AC is connected to a digital thermostat, it gets naturally cooler at night, so the outdoor temperature might dip below the automated setting to turn the cooling system off.

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.

To keep your air conditioner in good working condition, you should have it serviced by a professional at least once per year, ideally in the spring before the cooling season begins. If your AC unit is 10 years or older, consider servicing it twice a year (once in the spring and once in the fall) to catch potential problems early and help it reach its full lifespan. During a service visit, a technician will inspect, clean, and replace parts as needed. Regular maintenance helps avoid costly repairs. As a DIY task, you can also clean the evaporator coils annually.

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
