"I’m overly pleased with the work that Wells HVAC provided me. The heating/cooling in my home was antiquated, inefficient & unreliable. However, Michael & his expert-tech remedied those solutions for me. In addition to that; they were punctual in arrival times, they were neat & tidy, and something that stood out to me was their politeness! It feels so good not to be stressed about an unreliable climate & atmosphere in my home now thanks to Wells HVAC. I have, and will continue to highly recommend them to my friends, family, and associates. If you’re on the limb about getting a service done or whom to get it done by… Just call Michael, I promise there will be no regrets or disappointment!"

"Mast Electrical Services installed three outdoor GFCI outlets in the soffit of my house. I was worried that because there was no flooring in my attic that it would be an issue, but not for Mast Electrical Services. They arrived on time, performed professionally, did an outstanding job, and all for a very reasonable price. They even answered some questions regarding running low-voltage wiring through my walls that enabled me to perform that work myself. I strongly recommend Mast Electrical Services for your electrician needs."

Heating and Air Conditioning questions, answered by experts

Modern AC leak sealants work as a temporary measure to stop refrigerant leaks. You can purchase them at most home improvement stores or on online. When using an AC leak sealant, keep in mind that it’s only a temporary solution, so you’ll still need to hire a pro to install a replacement part as soon as possible.

If your whole house is cold that’s one thing, but what if you only have a few rooms that are cold? First, you need to determine why this may be happening. A good place to start is to investigate the potential causes listed in this article—heat transfer, airflow, thermostat problems, humidity, and insulation. Once you’ve narrowed down the issue, you’d apply the same principles to the cold rooms as you would to the entire home.

Some HVAC systems tend to use R410A refrigerant, although if you have an older model it may be using R22. R22 is banned due to its harmful environmental and health impacts, and it is a sign that your AC unit is old enough to consider a replacement and the significant efficiency gains that could come with it.

It depends on the specifics of your warranty. The motor is likely not covered if you’re working with a limited warranty. The same goes for other components like the compressor and evaporator coil. Some extended warranties will cover the blower and fan motor, so read the fine print before signing up. Additionally, the manufacturer may offer a warranty for the parts, including the motor, though there’s likely to be a strict time limit for this coverage.

If your AC runs constantly, it could be due to a number of things, including a faulty thermostat, incorrect temperature settings, or broken equipment. Alternatively, you might have an airflow problem (for example, blocked vents or leaky ductwork). Either way, an HVAC pro can identify the specific problem and fix it for you.
