"Air Heating & Cooling repaired ducts, replaced all grills, installed larger ductwork, bigger air supply vents in large living room & installed a new ceiling return. They drywall sealed unneeded return openings. Team came at 8am & worked diligently to install a complete HVAC system. They cleaned up any mess before they left. Jose and George really listened to my concerns of insufficient air flow in my 1978 home and made improvements. My home feels so comfortable and cool now. I look forward to less expensive electric bills. Thanks to God for their hard work. I highly recommend them for HVAC installation. A+++"

"While having our air ducts cleaned, mildew was discovered on the inside the supply plenum on our A/C unit in the attic (possibly from all the moisture Harvey dumped on us for days). Although the unit was only four years old, we decided it was best to replace it before it got worse. To hopefully avoid this type of problem in the future, we wanted to install some form of UV light in the plenum after it's replacement, but we were very concerned about the ozone that's released into the home's air from some of these types of lights. Matthew from Air Specialist listened and addressed all of our concerns about UV lights, and gave us information about each type on the market and which ones would address our concerns. After research, we decided on one of the Lennox UV lights and Matthew installed it for us. So far we've had no problems with this UV light, and we continue to be happy with Air Specialist's work."

"Outstanding Service from Start to Finish! I recently had my air ducts cleaned by Air Duck Cleaning HVAC, and I couldn’t be happier with the results. From the moment I scheduled the appointment, the team was professional, courteous, and highly responsive. The technicians arrived on time, explained the entire process clearly, and were extremely respectful of my home. They used high-quality equipment and took the time to thoroughly clean every vent and duct. The before-and-after photos they provided were shocking — I had no idea how much dust and debris had built up over time. Not only does the air in my home feel fresher, but my HVAC system is running more efficiently now. I also really appreciated that there were no hidden fees — just honest, quality work at a fair price. If you’re looking for a reliable, trustworthy, and skilled company to clean your air ducts, I highly recommend Air Duck Cleaning HVAC. I’ll definitely be using them again in the future!"

Heating and Air Conditioning FAQs, answered by experts

When faced with HVAC issues, it's best to begin by ensuring the thermostat settings are correct for either heating or cooling. If the system isn't responding, check the thermostat for proper function and power supply. It's also important to examine air filters, as clogged ones can decrease performance. Confirm the power supply to the system by checking the circuit breakers and fuses. If these basic steps fail to resolve the issue, contact an HVAC professional for a more detailed diagnosis and repair.

The cost to repair an air conditioner averages around $350 to $450, but the price can range from $100 to over $3,000. The final cost depends on the type of air conditioner, the extent of the damage, and the specific parts that need replacement. For example, repairing a window AC unit typically costs between $100 and $250, while central air conditioner repairs can range from $300 to $3,000. A simple fix like replacing a dirty filter might only cost $10 to $50, but a major issue like a broken compressor could cost around $2,000 or more, potentially making it more cost-effective to replace the entire system. Due to the need for specialty tools and handling of refrigerants, repairs more complex than changing a filter are best left to a professional.

When first installed, flex ducts shouldn’t cause airflow problems in your home. However, because flex ducts aren’t the sturdiest and require extra support, they lose their durability over time and begin to sag, which can inhibit airflow down the road. Also, if your flex ducts aren’t tight enough, your HVAC could work twice as hard for the same air pressure. If you’re worried about the airflow in your home, a rigid duct may be your best bet.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

Replacing both an AC and a furnace takes a full day on average, ranging from eight to 12 hours. The process involves removing the old units, installing the new ones, and ensuring all connections are properly made. If both systems are being replaced simultaneously, it can take longer than installing a furnace alone, so plan accordingly.
