"I met with about twelve hvac contractors as my project was a large job that included two systems and duct work. I met Erik last and he was the most straightforward person and did not try to up sell me. He painted the picture of what he would do and was confident in his proposal. When the work started it was smooth and detailed. Erik and his crew answered my many questions which helped me feel more confident. Overall a wonderful experience and value for your money. Erik included many items that other companies did not which helped the end product look and function better. Thank you!"

"Greg and Chris were very professional and clearly communicated all aspects of the job that was being completed. The arrived on time and cleaned up after themselves when the job was completed. They not only took care of my HVAC ducts and vents, but I had them also address my dryer vent cleaning as well. The work was priced fairly for the work done and thoroughly reviewed in detail. I would highly recommend The Duct Pros for your duct cleaning and will be using them again in the future!"

"Our 17 year old central air conditioning went out at the start of a heat wave. I called Arctic Fire on a Sunday morning. Alex returned my call that afternoon and came out the next day around noon and quickly diagnosed the problem and had our old unit running in about half an hour. In conversation with Alex I discussed the possibility of replacing my 17 year old unit which had been a problem with 3 previous service calls in the last year. Within a day he sent me an estimate which was very competitive and reasonable. Within 2 weeks he replaced both my compressor and air handler in a very hot attic. His team was very professional and completed the job in about 5 hours. Even in very hot weather his team remained focused and answered all my questions and concerns. He did not leave until everything was running and operating correctly. I would highly recommend Alex and Arctic Fire for any of your HVAC needs."

Heating and Air Conditioning questions, answered by experts

While it is possible to add Freon to your AC unit yourself, it is not recommended. In fact, the U.S. Environmental Protection Agency (EPA) prohibits the handling of Freon without a license. Freon is a dangerous gas that can cause irreversible damage to your AC or yourself if not installed correctly. It is worthwhile to hire a professional to add Freon to your AC.

Mold in your air conditioner isn't a good thing, as it can be harmful to your health. If the mold travels through the ductwork or is blown out of the A/C, you and your family can inhale mold spores and develop respiratory illnesses and other problems. Preventing mold from growing in the air conditioner will help protect your health.

To keep your air conditioner in good working condition, you should have it serviced by a professional at least once per year, ideally in the spring before the cooling season begins. If your AC unit is 10 years or older, consider servicing it twice a year (once in the spring and once in the fall) to catch potential problems early and help it reach its full lifespan. During a service visit, a technician will inspect, clean, and replace parts as needed. Regular maintenance helps avoid costly repairs. As a DIY task, you can also clean the evaporator coils annually.

Yes, ventless portable air conditioners exist, and not all standard portable air conditioners must be vented through a window.

Ventless portable units, often called evaporative coolers, do not have exhaust hoses. They use a water reservoir and a cooling pad to add moisture to the air, making it feel cooler. These units work best in dry climates because humid areas cannot absorb much additional moisture.

For standard portable air conditioners that do require venting, a window is not the only option; they can also be vented through a door, wall, or ceiling. However, it is essential to vent these units properly. Running a standard portable AC without venting it is counterproductive because it needs to expel heat to cool the room. Failing to do so will only increase the room's temperature.

If the air coming from your AC unit is cool but never quite cold, there are a few reasons this might be happening. For starters, it could signal that your refrigerant levels are low. If there are no other indications of this particular issue, like hissing noises or frozen refrigerant lines, anything from dirty filters to damaged condenser or evaporator coils could be responsible for the problem.
