"Had a great experience with Kamal. He is helpful, knowledgable and very dependable. We had a crisis with our old hvac system and were freezing. Kamal was the only one who came within 2 hours on a holiday while others were available only the next day or later. Most were closed that day. I got a great deal on the new SEER16 hvac and have been happy with it. My electric bill has cut down to almost half. Also he offers 2 years of his company’s warranty in addition to the manufacturers 10 year warranty. Highly recommend Kamal and will be using him for future."

"Needed a complete service on my furnace and A/C system prior to putting my house on the market in a few weeks. Magna Tech Temp Air did a terrific job at a very reasonable price. Showed up on time and got the job done right. Great customer service, good communication, overall great experience. Wore shoe covers to protect my flooring. Shout out to Albert, he even went above and beyond to help me with opening the indoor valves on my outside water spigots because I couldn’t reach them at 9 months pregnant. Definitely recommend this company. I feel confident knowing that when the home inspector visits my house pre-sale, my HVAC system will pass with flying colors."

"September 2019, my water heater broke and TC HVAC Services replaced it with a new water heater. And they also fixed my AC and fridge. Recently, in October 2019, TC HVAC Services installed a new humidifier in my home. Mr. Thea Chea, the specialist was professional, honest, and he answered all of my questions. The repairs and installation were completed in a timely manner. And costs were reasonable and fair. I would definitely use TC HVAC Services again and I have recommended TC HVAC Services to my family and friends. Thank you, Mr. Chea and TC HVAC Services LLC."

"I hired Air Quality HVAC to replace my aging HVAC system and I had a fantastic experience with them from start to finish. Amar was patient in answering all of my questions along with providing pros and cons for the various options. He assessed the situation whilst giving me comprehensive and thorough advice regarding the best way to proceed. Amar and his team arrived and began their work at the scheduled time. They took great precautions not to damage anything by placing cardboard over the flooring and they moved carefully throughout the home. They worked efficiently and effectively without rushing the job. When finished, Amar and his team did an excellent job cleaning up ensuring that no mess was left behind. If you're looking for service that is courteous, fair, and reasonably priced, then look no further than Air Quality HVAC. They provided a quality of service beyond my expectations, and I sincerely appreciate their commitment to honesty and professionalism."

"They installed a new boiler and central air conditioning in my DC rowhome and did a fantastic job. Joe answered all of my questions and they stayed on schedule with the project which was great because it was a larger project. I would highly recommend their services for the quality of workmanship and their prices were very reasonable as well. I will contact them again for future HVAC work in the DC area."

Heating and Air Conditioning questions, answered by experts

While many states do not have specific licensing requirements for HVAC companies, your local city or county might. It's always a good idea to check local requirements online and use a tool like Angi’s contractor license lookup to confirm that the company you’re considering is licensed. Regardless of licensing, you should always ensure the company you hire is fully insured to avoid potential lawsuits if a technician is injured on your property. Additionally, it is recommended to check if the company holds third-party certifications, such as North American Technician Excellence (NATE) certification or R-410A certification, which qualifies them to work with HVAC refrigerants.

The time it takes for an air conditioner to dry fully after cleaning depends on the unit's size and humidity levels. Most units will dry within two to four hours after cleaning, but check the manufacturer's recommendations for drying times. Make sure to leave the unit off until it's completely dry.

When an evaporator coil becomes faulty, it can result in various problems within your HVAC system. These problems could include reduced cooling or heating capabilities due to ice formation and obstructed airflow, along with increased energy consumption and higher bills. Additionally, a damaged coil may lead to refrigerant leaks, which are environmentally harmful and decrease overall system efficiency.

Ultimately, if not addressed right away, a bad evaporator coil can even lead to a complete failure of your HVAC system. That’s why timely repair or replacement is crucial to maintaining your family’s comfort and your HVAC’s efficiency.

Your AC might not cool after a power outage because of a tripped circuit breaker, blown fuse, or damage to the compressor or capacitor. If you notice your AC not working after a power outage, in most cases, the breaker has tripped or the system has built-in brownout and blackout protection. Reboot the AC by turning it off at the thermostat, resetting the circuit breaker, and waiting 30 minutes to turn the AC on again. 

Yes, it is possible. An electrical fire can break out if the compressor has inadequate ventilation. When it overheats but doesn't have a proper thermal cutout, this can cause the motor to short-circuit and catch fire. This risk is exacerbated if flammable materials, like dust and fallen leaves, are clogging the unit. The compressor overheating won't start a fire by itself, but poor maintenance and installation can increase the risk once it hits its breaking point and short-circuits.
