"Jesse came out to diagnose our leaky window and spent several hours going over it, our insulation level (turns out its pretty good) and other places where we were losing efficiency. His FLIR tool proved the window turned out not to need fixing. I am glad I asked him to come as I would have probably paid another company for a costly new window I didn't need."

"I had Maverick come out to replace a 58 year old fuse box, wiring, and installation of a surge protector. They sent Nate Alexander out to give me a 3 option package of what to choose from. I made the decision on the option and Nate was there two days later. He spent six hours doing the job Was extremely knowledgeable and very thorough. Nate not only was very professional, but so kind and polite. As he hails from Texas I can see the Southern good manners are very much a part of his personality. Although this is a young company, I can see why it has grown so rapidly. QUALITY and INTEGRITY. I had a great experience with Maverick and would highly recommend them to friends and family. Yes Ma'am I surely will !!"

"We hired McCormick to remodel our master bathroom, and the process couldn’t have been smoother. Khaled guided us through everything, and his team was skilled and respectful. They handled the job efficiently, stayed within budget, and kept our home tidy. Now, our bathroom feels like a relaxing oasis, with high-quality finishes and a modern touch we love. McCormick’s attention to detail really made the difference, and I’d gladly hire them for future remodels. This experience was everything we hoped for."

"I called ThermoTech Solutions and they sent out a technician within 24 hours. I was pleasantly surprised that the technician was the same gentleman I talked to over the phone so I did not have to retell what was wrong with my system. Jason my technician who is also the owner was great. He tested my system, knew exactly what was needed, and had it repaired the very same day. He did not try to sell me on upgrading my unit or a bunch of repairs I did not need. The service was fast, very reasonably priced, and I have had no issues since. Will definitely be having ThermoTech Solutions come out for all my HVAC needs in the future!"

Air Conditioning questions, answered by experts

It is normal for the attic to be hotter than the rest of the house in the summer, but only by about 10 or 20 degrees. Attics that aren’t properly insulated or ventilated can reach temperatures of 130 degrees or more which can cause damage to the home’s structure, including the roof, wood framing, and HVAC system.

It’s never a good idea to run your AC without a filter, even just for a night. The filter defends your HVAC system from the dust, dirt, debris, and other grime in your home. Without a filter, those contaminants are more likely to get inside your system and potentially damage it. 

For the most part, you should leave your AC fan in “auto” mode so that it only runs during a heating or cooling cycle. Keeping it in this position uses less energy, which equals lower utility bills. However, there are some situations where it’s better to leave your AC fan on, including if you have allergies or there are lots of people in your home.

If you don't clean your AC evaporator coils, dirt and debris will build up, which impairs the system's ability to transfer heat. This forces the unit to work harder, leading to inefficient performance, higher energy bills, and frequent breakdowns. Over time, neglected coils can corrode, which may cause refrigerant leaks, or develop mold, ice buildup, and a clogged condensate drain, resulting in poor air quality and an uncomfortable home.

The average cost to replace or install a new HVAC system is around $7,500. However, the price can range from $5,000 to $12,500, depending on factors like the size of your home, the type and brand of the unit, and your specific heating and cooling needs. If you only need to replace certain components, the cost will be lower; for example, a new AC unit can cost between $2,200 and $5,500, while a new furnace costs $3,200 to $6,000. If additional work like new ductwork is required, the total cost could be as high as $22,000. It's best to contact a local HVAC company for an accurate quote.
