"Just had my first service check up on my heating and air conditioning unit. As was the install the scheduling was easy. The technician called prior to arrival. I met him at the door and he explained everything that the service included. Then he went about his business. The report was concise and I am extremely pleased with his professionalism and manner. I highly recommend Maynor for your installation and service needs."

"From the moment we inquired about services to job completion, we had a great experience working with Air Quality Concepts for our HVAC air duct and dryer vent cleaning. The owner Charles was incredibly prompt with communication and took the time to answer all our questions about the cleaning process prior to scheduling. We were so impressed by how personable, hard-working, thorough, and efficient our technicians Austin and Michael were when they cleaned our two HVAC systems. They were very attentive to the issues we have been having with our indoor air quality as we navigate mold remediation and health concerns. The company’s customer care was genuine and so appreciated, and the cost of services was very reasonable. We already feel more comfortable in our home knowing we are breathing cleaner air! I highly recommend Air Quality Concepts if you are looking to improve the air quality of your home!"

"From my consultant, Terry H, to installers Moises A & Jose L, and the office support staff, everyone did an awesome job. Terry reviewed our needs and recommended a high quality Mitsubishi mini split heat pump to condition a garage/workshop, that effortlessly cools what used to be a super hot garage. Looking forward to experiencing how well it heats this winter. Moises and Jose were top notch installers who did an extremely professional and ultra neat job getting everything installed and working great. The office staff was also on top of scheduling the install, walkthrough, and final inspections. Everything went very smoothly. I highly recommend Carolina Comfort Air."

"My overall experience with that a thermo direct was positive my only issue was that they trampled some ground cover I had around the air conditioner never mentioned it to me. That being said, who would not be happy to have ac on a 90-degree day after a hot evening without ac. Lastly thermo direct was very responsive. They showed up quickly!"

"Dominion Services replaced my 30-year old HVAC system (the outside compressor, and the inside air handler) with a modern one having a 50% increased efficiency rating. The quality of their work is high (four friendly employees with more than 100+ years' combined experience were involved) and have good flexibility to adjust to my work schedule. They easily adapted the new system to the existing hook-ups, and were flexible in their selection among alternate, reliable replacement HVAC systems. The replacement cost was well within the range of the national average. I recommend contacting Dominion Services for insight into any HVAC issue."

"Parker Heating and Air effectively described the issues with my HVAC system. I was presented options for repairs and I trusted Drake the tech onsite to make the best choice. My AC was back working in the next hour thanks to his hard work. Highly recommend!"

Small jobs welcome

"Very satisfied with the outcome. The house was not occupied while this work was being done, so I was not present during much of the work to observe the installation of system & ductwork, but it worked beautifully once we moved in and began to use it, a turnkey experience. Twice since then we've had questions (e.g., Can we move the ductwork in one part of the attic to accommodate new attic stairs?), and both times they were very responsive and came out at no charge to me, despite the fact that the work was done over a year ago. I've interacted with both Mike (the owner) and with one of his technicians, and have been very satisfied with the level of customer care I've received. I will use them in the future for our heating & A/C needs.

Air Conditioning FAQs, answered by experts

A blocked return air vent can cause your HVAC system to work much harder and, therefore, less efficiently. The result is higher utility bills and poorer air quality. A blocked return air vent can also cause unpleasant dust, dander, and odors to linger in your home’s air.

In most cases, you should hire a professional to carry out services on your HVAC system, as the components are complicated, expensive, and potentially dangerous to work with. However, there are a few things you can do on your own to keep your HVAC system in good condition, including changing your filters every three months, keeping the area around your outdoor condenser clear of debris and plant growth, making sure your or intakes aren’t blocked, and keeping an eye out for increased energy bills, strange noises, and unusual odors related to your equipment.

Yes, a dirty air filter can cause a higher electric bill. That’s because clogged filters make it harder for air to flow through your HVAC system, which forces it to work harder and use more energy. According to the U.S. Department of Energy, replacing dirty filters can save you between 5% and 15% in utility costs.

If you have central air conditioning, it’s fine to run your AC all day if that’s what you want—as long as the AC unit is in good condition. But if your AC runs constantly when you don’t want it to, there may be a problem with your system (like the ones we’ve mentioned above). Window AC units and wall air conditioners aren’t as powerful as central AC, so you should only run those kinds of air conditioners for eight to 12 hours at a time.

Most HVAC service calls include diagnostic fees, which could include checking on a specific issue you’re experiencing or running through a routine inspection checklist. If you called for a particular problem, the service call will also include an estimate to fix the issue, including materials and labor. Depending on your HVAC technician and the service you requested, you might also get a general inspection of your system components to ensure everything is working as intended.
