"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"

"Great company. I am very pleased with the installation of the replacement gas furnace, digital WiFi thermostat, filter system, and water safety package with drain pan. The technicians, office personnel and owner were very knowledgeable. Very courteous, answered questions I had on the new furnace by Amana. Also very pleased with the maintenance of the other HVAC system installed at my house. Will recommend them to my friends."

"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."

"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."

"We had some issues with our HVAC. Asked for a quote based on what we thought the issue might be. The team at I-HVAC responded promptly, talked us down (aka explained we didnâ t need what we thought we did), and showed up same day. Prompt, courteous, professional."

Heating and Air Conditioning FAQs, answered by experts

The cost to replace an AC evaporator coil is typically between $600 and $2,500, with an average cost around $1,300 to $1,350. The price of the coil itself can range from $550 to $1,100, depending on the brand, size, and style, with professional labor adding around $700. Replacing a condenser coil is generally less expensive, costing about $800. Because this repair involves handling refrigerants, it requires a licensed AC professional. Regular inspections, which cost between $200 and $600, can help prevent costly coil replacements.

Many HVAC companies offer free quotes and free estimates for repairs and new HVAC systems. Others offer low-cost quotes or apply the cost of the estimates or diagnostics to your final bill if you hire them. Be aware that some companies advertise free HVAC quotes and recoup the costs by charging more for their services. Free HVAC quotes are never truly free—they cost the company time and effort—so be a good customer. Also understand that you may end up paying for free quotes in another way if you don’t hire a reputable company.

ACs don't run on water. They're not connected to drain pipes or any part of your plumbing system. However, they need refrigerant to run. Refrigerant is a gas or liquid that has a low boiling point and absorbs the heat in your home. ACs need this in order to be functional and cool your home. If you suspect your AC is low on refrigerant, you need to contact a licensed HVAC professional. Refrigerant is a dangerous chemical that requires specialized training and permits to work with. 

Set your house temperature between 55 and 85 degrees Fahrenheit while on vacation, depending on the season. If it’s winter, don’t go below 55 degrees. In the summer, the best AC temperature for energy savings is no higher than 85 degrees. You can save anywhere from 10% to 15% on your energy costs by adjusting the temperature while you’re away. If you have a smart thermostat, set up vacation modes for each season. On your way home, turn off vacation mode to allow the home to warm up or cool down before you arrive.

Most units are designed only to cool the house down to 20 degrees less than the temperature outside. This means that if it’s 99 degrees Fahrenheit out and you’re trying to cool your home down to 65 degrees, you’ll notice your AC is struggling. 

Lower the blinds on all your windows, turn on your ceiling fans, and keep the thermostat at a consistent temperature to help your AC do its job. Investing in an HVAC maintenance plan also helps because pros will come out to inspect and tune up your unit regularly, keeping it in optimal working condition.
