"Sean was great about repairing my disconnected dryer air duct having to go into the crawl space and figure out what was going on. I'm glad he was able to get it done very quickly as well. He also had a very good attitude about doing the work."

"We had Temp Air install our AC unit. The best decision we ever made. They were fast, reliable and dependable. Excellent customer service, did a phenomenal job. After a couple of years something was going on with our unit, I called them and immediately they send out a technician Juan, who was phenomenal. He explained what the issue was and resolved it asap! Highly recommend this company!"

"I highly recommend Belle Air Services! From the first moment I called to get a quote, to the moment they finished the job, I could not have asked for better customer service, top notch work, and competitive pricing. They communicated with me all throughout the process, made sure I understood everything that would be done, were on time, protected my home and were clean. They even worked very well with my HOA (who is very tough!). And to top it off, they didn't try to up-sell me as other HVAC contractors have in the past. So pleased that I have found this HVAC company!!"

"Chris came by for a normal AC tuneup and as he was finishing up, we told him about some issues with our dishwasher and master bathroom sink and asked if he knew a plumber. He took care of both our problems right then and there! I’m not sure there’s anything he can’t fix. Chris is our go to guy for EVERYTHING ac/furnace/plumbing and he should be yours too!"
After: brand new furnace with industrial grade filtration system. Re-wrapped ductwork with fiberglass free wrapping and acoustic soundproof closet/return cavity.
After: 2 Stage Variable Speed Furnace installed perfectly!
After: Properly sized, energy efficient, and installed to code.

Air Conditioning FAQs, answered by experts

Split systems are the most common type of HVAC system. Split systems have two main units: an indoor one and an outdoor one. These units work together to pull in air, heat or cool it, and distribute it throughout your home. Other popular types of HVAC systems include hybrid systems and packaged heating and air systems.

One of the first signs of mold in an air conditioner is a musty smell. You're likely to notice the smell when the unit runs, from the air coming out of the vents or the unit itself. You may also be able to see mold growing on the unit, such as near the condenser coils or by the fan. In some cases, there may be visible mold by the vents.

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.

If you’re planning an AC replacement, choosing an AC with a higher SEER rating may save you money in the long run. Tax credits could cover as much as 30% of the job, and you’ll notice smaller utility bills (particularly if you live in a hot climate where you need to constantly run the AC). Generally, you can expect to pay between $350 and $1,500 for each SEER rating increase. Weigh the cost against your typical utility bill to figure out what’s worth it to you.

High humidity, bad insulation, warmth from sunlight, and poor circulation are all reasons your home’s hotter inside than out. While this is what you want in the colder months, summer can become unbearable if this is a constant. Try to find the cause, but you need to remember that issues like this require a permanent fix (unless you want to bear down during the summer months).
