"Clean Air Ducts and Vents - Doctor Ducts was great to work with. Excellent customer service and very detailed in explaining what was being done with my furnace and air ducts. They took pictures of what my vents looked like before/after. I would recommend them and will use their services again."

"In the midst of the hot weather, our A/C decided to stop working. My friend referred Priority. They were able to make it out to me very quickly and repair our A/C at an affordable price. The guys were very knowledgeable and helpful in explaining how things work and what was wrong. I would definitely recommend Priority for any heating and cooling needs."

"We were very impressed with A & C Heating and Cooling. Their online scheduling tool was convenient, user friendly, and there was a variety of time slots available. The appointment follow up, reminders and arrival tracking map were timely and helpful. Our technician, McKinley, was amazing!!! He was very courteous, knowledgeable and efficient. He diagnosed the problem quickly, installed the needed part, and ran tests to ensure the unit was running at peak performance. He educated us about our unit by explaining how it operates, what caused the problem, and how the replacement part would remedy the problem. We are VERY satisfied with their service. We give this company and our technician our highest rating, and we would highly recommend them to anyone in need of quality heating and cooling installation or service. ."

Air Conditioning questions, answered by experts

Whether an HVAC damper should be open or closed depends on the season, the zone it controls, and the temperature in that zone. In the summer, open upstairs dampers and close lower-level dampers to get the most efficient cooling possible. In the winter, do the opposite. Cool air will naturally flow down to lower levels, while warm air will rise. This keeps your system from working harder and helps prevent common AC problems.

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).

The best way to save money on HVAC repairs is by regularly having your system inspected and maintained. This can prevent bigger problems and costly repairs and replacements in the future. It’s also smart to buy quality equipment and hire companies that provide warranties on equipment and labor. If you need repairs, you may be able to save money by cashing in on rebates and incentives or keeping the area around your HVAC unit clear to shorten the time your contractor needs to spend in your home.

Yes, government incentives and programs are available to encourage energy-efficient upgrades in many regions. These incentives may include tax credits, rebates, grants, and low-interest loans for homeowners who invest in energy-efficient improvements such as HVAC system upgrades, insulation, and efficient windows. The availability and specific details of these incentives can vary by location, so check with your local government or utility company to explore your options.

Here’s the cost formula to find out how much it’ll cost you to run a window air conditioner in your home:  Watts * (hours used) / 1,000 * (Local kWh) = daily cost of running a window unit. If you need help calculating the cost of running your window AC unit, consult an AC repair or installation pro for an accurate estimate.
