"My AC failed and I had limited time to find a good solution, I made a phone call to Relax HVAC based on the online reviews and it was a great decision. Nasser came to check the situation, he gave a very detailed and comprehensive overview of the situation and provided with the options I had. I decided to replace the unit, Nasser went above and beyond to find a unit delivery service but there was nothing available over the weekend so this gentleman went for unit pick up himself and finished the installation within a day from my initial call. Moreover, the provided price was very reasonable.I can't be more happy with the outcome and highly recommend Relax HVAC"

"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."

"Oullette's team was able to complete the installation in two days and haul away the old units. The new system is much more effective with consistent temperatures throughout our home. As well, it is much more efficient with demonstrably lower electric bills. We wholeheartedly recommend this company."

"I recently had the pleasure of experiencing the exceptional service provided by Air Quality HVAC LLC, specifically their technician Jay Vardhan. In the midst of a chilly evening with temperatures plummeting into the 30s, my nearly 20-year-old Lennox HVAC system decided to stop heating. Having dealt with major HVAC service companies in the past, where the experience often felt like a battle of wits against deceptive practices, I approached this situation with a sense of trepidation. Upon the recommendation of a neighbor, I decided to reach out to Amar from Air Quality HVAC LLC. To my relief, Jay Vardhan was dispatched to my home within an hour, accompanied by a reasonable service fee. From the moment Jay stepped into my home, it was evident that he was not your average technician. Jay's professionalism, technical competence, and, above all, his honesty, set him apart from the rest. Unlike previous encounters with other companies, Jay took the time to methodically run checks on my HVAC system, explaining each step of the process with clarity and patience. His knowledge was not only evident but also accompanied by a genuine desire to educate and inform rather than exploit. What truly stood out was Jay's honesty and transparency. He provided insights into potential issues and presented a range of options without any hint of upselling or deceit. It was like having a conversation with a trusted friend or family member who genuinely had your best interests at heart. The issue with my HVAC system turned out to be a tripped limit switch, and Jay, with his commendable patience, navigated the challenging design of the Lennox system to reset it and restore functionality. The level of dedication and commitment displayed by Jay was truly commendable. I would like to express my sincere gratitude to Jay Vardhan and Amar from Air Quality HVAC LLC for providing a service that goes beyond the norm. In an industry where honesty and integrity have become rare commodities, encountering professionals like Jay is a refreshing and reassuring experience. The work was done efficiently, and my trust in HVAC technicians has been restored. I wholeheartedly recommend Air Quality HVAC LLC for their exceptional service and commitment to honesty in an industry where it is often lacking."

Heating and Air Conditioning FAQs, answered by experts

Yes, AC coil cleaning is definitely worth it. Cleaning your AC coils ensures your AC unit will function efficiently for the long term. Dirty and grimy AC coils make your unit work harder to cool your home, resulting in higher electric bills. Additionally, having your coils professionally cleaned regularly will reduce the possibility of extensive maintenance and repair costs.

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.

They can, but it’s not as common. Window AC units are much smaller than whole-house systems and less likely to develop refrigerant leaks or similar issues. As a result, you will rarely need to add a new refrigerant, limiting overcharging problems. However, it’s still important to leave refrigerant management in the hands of professionals when window units need work.

There are many recognizable symptoms of AC compressor failure. They include loud banging noises, hot air being continually circulated in your home despite running the AC at full blast, uneven airflow and cooling, and electrical issues like constant surges due to the compressor working overtime. While some of these symptoms, like uneven cooling, can have other root causes, they are common indicators of compressor problems.

Yes. Getting a whole-house dehumidifier can help you save money on energy bills. How? Your home automatically feels cooler when there’s less humidity in the air (“It’s the humidity that gets ya!” is such a true statement). This means that you won’t need to run your AC as much as you would if you had all that extra humidity in your home.
