"Excellent! The team worked diligently for 5 days to install a central air system in our old house with Plaster Walls. It was NOT easy, yet they did a fantastic job. They were able to add all ducts to the first floor with out any "chases" or enclosures requiring to be build. And almost none of our first floor lines up with our second floor closets, but they figured it out. Great time and fantastic service. Make sure you get Brandon and Sean. The work their butts off, and ensure your house stays clean (they cleaned up everything after every day - not an easy feat). Cannot say how happy am I with their work!"

Josh assessed the issue and was able to locate and obscure component within about an hour. Not only did Josh fixed the shower but it worked better than it did when it was new! This company and its technicians are incredible! If you need Plumbing or HVAC services do yourself a favor and call Advance professional"

"I can't say enough great things about J & M Cooling and Heating! The installation of my new central air system was an outstanding experience. A special thank-you to Dan, the supervisor, who made sure everything went smoothly from start to finish. He was professional, knowledgeable, patient, and took the time to answer all of my questions. It was clear that he genuinely cared about making sure the installation was done right and that I was completely satisfied. I also want to recognize the incredible installation team. They spent days working in an extremely hot attic installing my new system, and despite the challenging conditions, they never once complained. They worked tirelessly, stayed professional, and remained courteous and respectful the entire time. Their work ethic, positive attitude, and attention to detail were truly impressive. They treated my home with great care and left everything clean when the job was finished. My new central air system is running perfectly, and I"

Heating and Air Conditioning FAQs, answered by experts

Freon will go in the refrigerant lines near the back of your AC unit. Look for small ports with caps on a thin copper line—the Freon goes into those ports. You are best off hiring a licensed HVAC professional who can complete the job safely and correctly.

Signs that your A/C system needs professional service include increased energy bills, uneven or poor cooling, loud or unusual noises, and frequent cycling.

They can, but it’s not as common. Window AC units are much smaller than whole-house systems and less likely to develop refrigerant leaks or similar issues. As a result, you will rarely need to add a new refrigerant, limiting overcharging problems. However, it’s still important to leave refrigerant management in the hands of professionals when window units need work.

In most cases, you should hire a professional to carry out services on your HVAC system, as the components are complicated, expensive, and potentially dangerous to work with. However, there are a few things you can do on your own to keep your HVAC system in good condition, including changing your filters every three months, keeping the area around your outdoor condenser clear of debris and plant growth, making sure your or intakes aren’t blocked, and keeping an eye out for increased energy bills, strange noises, and unusual odors related to your equipment.

When your AC contactor goes bad, you might hear chattering or buzzing noises coming from your air conditioner. You may also notice that your AC is running but isn’t cooling your home. In some cases, your air conditioner might not even turn on at all. There could also be physical damage, discoloration, or corrosion around the contactor.
