"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!"

"Zach did a great job fixing my central air: He arrived within one hour of my initial phonecall on a Saturday morning and recognized that the electrical voltage transformer of my aging HVAC system had burned out. He advised me that the transformer had to be replaced and there could be problems elsewhere in the system that triggered the transformer to burn out.  
While Zack prepared me for the possibility of additional repairs that might be necessary, it turned out that the system was restored by replacing a relatively inexpensive component.  
I have used other companies over the years and been unhappy with price and/or professionalism.  I don't like using one-man show companies and I had used a much larger company until they sent an unprofessional repair person to my home.
I am very pleased with this medium sized company: they coordinated the repair nicely.  I always felt I was talking with a person who knew what was going on and what needed to be done at each point and got to my home expeditiously,  There were no surprises: Despite the weird name, Pipeworks is now my "Go-to company" for HVAC matters."

"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

The cost to add Freon to an AC ranges from $100 to $350. It can increase up to $600 for large AC units requiring much more coolant. The cost also depends on how much refrigerant your unit needs. If only a small amount of Freon leaked out, your cost would be on the lower side. A complete replacement of all the required refrigerant can get expensive.

High humidity is one of the most common reasons for air vents to sweat or produce condensation. When the cool, dry air from your HVAC unit meets warm and moist air in your home, it will cause condensation. Insulating your ductwork can help prevent this. If you live in a very humid region, a dehumidifier can also help.

A dirty AC filter can lower the efficiency of your system, so depending on how dirty it was, you may notice a temperature difference when you clean your filter. You can try other solutions if your AC isn’t blowing as cold as it used to. You can call in a local HVAC tech to make sure everything is running correctly, fix your air seal if it’s a window unit, and clean your coils.

It depends on the size of the space you’re cooling down. If you’re looking for the most affordable way to cool an entire house over a long period of time, then central air will be more cost-effective. But when it comes to cooling down a couple of rooms or one floor, a window unit may be the cheaper option, with both a lower cost to install and less energy used to run.

Troubleshooting common issues with your AC often sheds light on a problem with the compressor. Signs that you need to replace a bad compressor include your AC blowing warm air, short cycling (turning on and off), making strange noises, and blowing less air overall. Since these problems can stem from several areas of your AC, always call a local AC repair team to confirm it's the compressor.
