"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."

"Angel was the first one to come out and ran the diagnostics on our old AC unit. With the use of a camera, he showed us the rust, decay and water damage inside. His knowledge was vast, and, if the pictures weren't enough, he was upfront and honest that we should replace the entire system before more damage was done. Also, compared to other HVAC specialists' quotes that we received none were better than MSP's. It felt great knowing that we got a great deal. Within a few days, a mighty team of two, Nate and Jose began replacing our ancient AC with a more powerful one that would cool our 2-story house from top to bottom. The guys were courteous, professional, and extremely hard working. Besides the excellent job of cleaning up, they also installed a new thermostat and took the time to show my wife and I how to use it. In the end, no one like's when their AC breaks down, especially during a hot California summer, but Angel, Nate and Jose saved the day. So to those 3 guys, thank you for keepin' us COOL!"

Customers say: Quick response

"Nathan is very experienced and knowledgeable. He responds quickly to every text and phone call. He and his crew show up on time, work diligently, are respectful, and focused, and do all the little details like caulking and matching paint. They installed a 5 unit mini-split system and totally completed in 2 days. The price was very good and he even passed on the incentive from the manufacturer. There are always unexpected hiccups in every construction / installation job and there was no complaining, no extra charges, he just handled them quickly and efficiently. All in all, excellent work, excellent service. We highly recommend NT Electric and HVAC."

Heating and Air Conditioning FAQs, answered by experts

Vents may blow air even though the air conditioning system is off because of the pressure difference between indoor and outdoor air or drafts from leaky ducts. Check for leaks or drafts in the ductwork or around windows and doors.

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.

The outdoor portions of air conditioners are designed to weather the rain, so you don’t need to worry about it. An awning or roof will help protect them from snow or falling debris, which can do more damage. This is true of both window AC and outdoor units for larger systems.

There are several steps you can take to prevent your AC drain from clogging. This includes cleaning the drain line at least every three months, changing the filter every one to three months, and getting your AC serviced annually. Also, if any problems arise with your AC, hire an HVAC technician to deal with them ASAP.

The standard rule for return duct sizing is that the return vent should be the same size or larger than the supply vent. This will ensure balanced airflow in your home and reduce strain on your HVAC system.
