"Great. My daughter contracted Air Duct Professionals to do her home. James, the technician, was professional, knowledgeable and did a quality job. I contacted Air Duct to do my home and requested James. James arrived on time and did an excellent job. He also helped me with a leak with my HVAC Condenser and diagnosed and fixed the issue."

"I needed a smart thermostat installed and Victor, owner of United Air Heating & Air Conditioning, did a great job. He contacted me right away, quoted me a very fair price and we set up an appointment within a few days. He did a very thorough job installing the thermostat, plus took the time to explain some of the basics to me about programming it, etc. He also put down a drop cloth to protect my floor, which I noted. Other contractors have just let debris fall onto the floor (and left it there for me to clean up). He also gave me some helpful advice about my ductwork and other things. He was very personable, professional and his service was very reasonably priced. I can definitely recommend him and will hire him for any future HVAC needs. Thank you, Victor!"

"My HVAC unit stopped producing heat so I called the folks at around the clock. They offered to come out the same day and after taking a look up on our roof determined it was a faulty control board. We talked a little about the lifespan of the unit and that while it was probably going to need to be replaced in the next 5 years or so, it made more sense to simply replace the board today. So he scheduled an appointment for the following day to come back with the replacement board. 1 day later and 15 minutes of work and I have heat again."

Heating and Air Conditioning questions, answered by experts

While it's generally safe to stay in a home with a coolant leak if your home is properly ventilated, it's important to have a professional come out to assess the situation right away. You should evacuate your home if you notice any powerful fumes. Additionally, you should leave your home if you are experiencing headaches or dizziness.

There are two main reasons your furnace and AC are turning on at the same time. The first could be that you’re confusing the furnace with the blower. The blower is located in the furnace and will turn on to distribute cool air from the air conditioner through the ductwork in the home. This is normal. If the actual furnace is turning on at the same time as the AC and hot and cool air are coming into the home, it could be a result of incorrect writing to a new thermostat or new systems.

Yes, HVAC zoning systems offer energy savings by allowing precise temperature control in different zones in your home. Rather than conditioning the whole house uniformly, these systems direct airflow where needed, preventing energy waste. Tailoring comfort to specific areas reduces energy consumption and lowers utility costs, making HVAC zoning an energy-efficient choice.

You will enjoy greater energy efficiency and save on your annual energy bills, with new, modern HVAC systems using 30% to 50% less energy than older models. Upgrading your HVAC system is also a great way to embrace new technology, such as smart thermostats, lighting, fan speed, and humidity from your phone or tablet.

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.
