"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"

"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."

"Joe and his team were fantastic in replacing our old HVAC Units. I really appreciated Joe’s willingness to hop on the phone with me whenever I had questions about the estimate or the work being done. He was very patient and never overbearing. The work was done correctly and quickly. The price was competitive compared to other quotes I received. I even had to call Joe a year after the work had been done to pick his brain about an attic renovation that might have had some impact on the HVAC system. Even though the question wasn’t going to lead to any more business for Polar Bear, Joe took the time to answer my questions about the potential impact of the renovation on the HVAC system. Truly appreciated his high level of customer service! Would definitely use Polar Bear again!"

"McCrea replaced a 20 year old HVAC system with a new Trane 4-ton XL16i condenser, XV80 furnace and new coils. The salesman, Mark, was very responsive to my request for quote changes or additional items, including financing options. He was very knowledgeable and patient through the entire process as I worked with other companies for competing quotes. As a result of Mark’s recommendations and excellent pricing, I added on a new Aprilaire 1210 filter box (including replacing a portion of the return duct work/box) and an Aprilaire 600M whole house humidifier. I was able to schedule install four days after signing the contract. The installers, Charles and Christian, arrived on time and removed the old and installed the new in about 7 hours. They provided an overview of system operation and cleaned up so well, you couldn’t tell that a significant installation had occurred. I would recommend McCrea, especially Mark, Charles, and Christian to anyone...they were professional and did an excellent job. My home is so much more comfortable with a system that will be better on the summer and winter utility bills."

Heating and Air Conditioning questions, answered by experts

Excessive humidity in a room often manifests through visible signs like condensation on windows or walls, a musty or damp odor lingering in the air, peeling wallpaper or paint, and the presence of mold or mildew. Experiencing discomfort due to a consistently clammy or sticky feeling can also indicate high humidity levels.

There are plenty of different not-so-great sounds to hear from your air conditioning unit, like squealing, grinding, water running, excessive gurgling, banging, and clanking. Each of these sounds can indicate a different malfunction with your unit, so it’s important to have a professional assess the problem before it gets worse.

Deciding whether to replace just the AC coil or the entire system depends on the age of your unit and the overall cost. Replacing a coil is less expensive than a full system replacement, but it can still be a pricey repair. If your HVAC system is relatively new and still under warranty, or if the replacement cost is significantly lower than a new system, replacing the coil can be a worthwhile investment that restores efficiency and extends the unit's life. However, for older systems (nearing the end of their 10-15 year lifespan) or those with extensive damage, it is often more cost-effective to replace the entire AC unit. Mismatched coils in an older system can lead to inefficiency and future breakdowns, so a full replacement ensures optimal performance and avoids further costly repairs.

The average cost to replace or install a new HVAC system is around $7,500. However, the price can range from $5,000 to $12,500, depending on factors like the size of your home, the type and brand of the unit, and your specific heating and cooling needs. If you only need to replace certain components, the cost will be lower; for example, a new AC unit can cost between $2,200 and $5,500, while a new furnace costs $3,200 to $6,000. If additional work like new ductwork is required, the total cost could be as high as $22,000. It's best to contact a local HVAC company for an accurate quote.

Running an air conditioner with mold is not safe because it can spread harmful mold spores throughout your home. Exposure to these spores can trigger various health problems, including respiratory issues, allergies, coughing, wheezing, sneezing, itchy eyes, and a sore throat. It may also aggravate asthma in household members. Continued exposure can increase the risk of more serious illnesses like sinus infections, pneumonia, and bronchitis. If you suspect mold in your air conditioner, you should stop using the system until it has been properly cleaned to avoid health risks and further contamination.
