"Chose Brothers via Angi to determine our heat pump problem. Their assessment led us (given it's age) to decide to replace the system. I obtained multiple quotes and Brothers was priced the best. They promptly installed a new system. All of the guys involved like Matt, Andrew, Shawn & Jamal (forgetting the electrician and another tech guys name, but they all) did an excellent job. I would highly recommend using Brothers for your HVAC needs."

"I would absolutely recommend Cool Comfort Heating & Air Company.  I have dual systems installed by them in my home.  They replaced one of them in the spring last year.  They are the only ones I use.  I would continue to use them in the future."

"Amitai from The Better Home Pros came today to inspect my hvac air duct system, I was having really bad allergies and sneezing and watery eyes for the past couple of months and I just could figure out what was causing it. During the inspection there was mold found throughout all of my air ducts in the house, Amitai showed me videos from the inspection report and than sent everything to the office to give me a quote, the quote was very reason in comparison to research I did but most importantly the quality of work that was done was AMAZING!!! I can already feel the difference in the air quality in my house it feels much lighter and smells better, I am so glad I called this company it was definitely worth it. I highly recommend anyone to use them for any hvac needs you might have and especially recommend Amitai the technician he is very polite and I felt really comfortable with him in my house and I just felt like he was really honest with me which means a lot these days. Thank you so m"

"They are so great.  From Samantha who answered the call, to Steve who came out for repairs they made me feel like my job was the only thing important to them at the time.  When I called back a couple weeks later looking for a written statement of what the professional had done to provide the buyer, they obliged.  I had the information emailed within minutes.  If I was staying in NC I would serisouly use them for all of my HVAC needs without hesitation!  I will recommend them to all of my friends any family."

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.

A new HVAC system can increase your home's value by about 5% to 7%, which can translate to an added value of $2,500 to $3,000. The return on investment (ROI) can be around 30%, especially if you upgrade the entire system, including ductwork and insulation. Adding modern features like a smart thermostat can further increase your home’s value by making the heating and cooling systems more efficient and convenient. However, since a new unit can cost $10,000 or more to install, it's important to weigh the upfront cost against the potential increase in home value. For a specific assessment, it's best to consult a local AC installer.

Though it may seem redundant, you can absolutely have a central AC unit and a window AC in your home. In fact, if you place a window AC unit near your central air, it can help move the cooler air throughout your home. But doubling up on your AC methods can get pricey, so factor in cost accordingly.

A non-maintained AC is more likely to perform poorly, increase your energy bills, and undergo more severe issues like breakage and water damage. That’s why DIY cleaning or professional maintenance is recommended annually. Otherwise, you might end up paying more in the end than you would for annual service. You can purchase cheap AC cleaning kits if you prefer going the DIY route.

If your central AC is not blowing cold air, you should try resetting the system. Many systems have a reset button. Make sure your thermostat is off, then turn off the circuit breaker that powers your AC. Hold the reset button for three to five seconds, then turn the circuit back on. Set your thermostat to cool and choose a temperature cooler than the room. Your system should turn on quickly.
