"Two visits and that's not our fault: Brian came, diagnosed the problem (capacitor if not blower died, and tune up). He was right: a new capacitor made it work well, until the old blower just refused to obey. Two days later we called and said that Brian was right: the blower needed replacement. Doing just the capacitor was our call to try to save money. Now our 20+ year old furnace runs like new. And I'll be calling them to replace our HVAC ('cuz it's 20+ years old) when it decides to give up the ghost."

"Swimmingly. I interviewed quite a number of HVAC companies for this job by sending out an RPF (Request for Proposal), and Bob Mamayek was unquestionably the most thorough in his on-site evaluation. Installation crew was fantastic. This is a small shop, and it was a true pleasure to have a team of regular guys just getting the job done. I recommend them without reservation. I almost gave them a B for responsiveness because Bob doesn't do a lot of email, but I realized while typing that this would be completely unfair, for two reasons. A) Bob might not respond to email with email, but he did always respond with a phone call. Frankly, that is better on many counts. B) This ignores the amazing response to my RPF, which was both timely and thorough. So, really, this says more about my email-centric life than Mamayek's responsiveness."

"The owner of Guardian Heating and Cooling, LLC (Steve Peterson) and one of his sons (Adam) did an AWESOME job installing a new, high-efficiency, gas-fired Laars combi-boiler at my residence! If the new unit continues to perform as well as it is presently, and Guardian service continues to be this excellent in the years ahead, I will be a happy camper and pat myself on the back for having been smart enough to hire them. :-) The unit they replaced was built by a highly-regarded manufacturer that had been installed by another highly regarded contractor by the previous owners of my home. As it turned out, the previous heating unit was a money pit and the previous contractors technical abilities left much to be desired. Each heating season, the previous boiler experienced one significant failure after another. The previous contractor kept changing parts without digging into **why** the parts were failing. They simply said I should accept this, since the unit was **old**. Unhappy with this response, I decided to cut my losses. To the rescue: Guardian Heating and Cooling! While not the least expensive contractor, Steve, and Son exceeded my expectations simply by meeting them! They arrived one time and did everything they said they were going to do. With unseasonably cold weather in October, I was initially a bit apprehensive at the prospect of having no heat for a few days while a replacement system was installed. I wondered if they would be able to complete this project in a timely manner, as they said they would. My worries were for naught. There were no surprises and no surprise expenses ... no nickle-and-diming when Guardian needed an extra part or fitting ... no drama. Guardian simply got the job done. And they did it beautifully. They took care to minimize the time I would be without water and without heat. After installation, they thoroughly tested the unit. The next day, they checked back to ensure that I was satisfied with its performance. They also cleaned up reasonably when they were done and were carefully not to damage my property, as they moved large, heavy pieces of equipment and tools around. In summary: a big Thumbs Up for Guardian heating and Cooling, LLC!"

"Quick personal response to my initial request. All other vendors responded with generic email, or automated call/voicemail. Josh was to the point, yet personable. He arrived with Kevin and took care of my situation in a fast and professional manner. Felt very comfortable during the entire process! Do your self a favor and call Josh for all your HVAC ne"

"Shane was able to schedule a prompt appointment. He arrived on time and performed a thorough diagnostic on the furnace. He identified an issue I was unaware of and corrected the problem with the air conditioner using parts that were still under warranty. I will gladly use his services again."

Heating and Air Conditioning FAQs, answered by experts

It’s normal to hear a low humming sound as air moves through your vents. Most of the time, you probably won’t even notice it. However, if that sound becomes disruptive or if you hear more concerning noises (such as rattling, clicking, banging, hissing, or grinding), there might be a problem with your HVAC system.

Yes, it’s best to turn off an AC unit that’s blowing hot air to prevent system damage and avoid expensive energy bills. If you let the AC continue running, it will put more strain on the condenser coil and compressor. Plus, if the AC is blowing hot air because of a refrigerant leak, it can also lead to a frozen evaporator coil.

While "dry" mode on your AC can help reduce humidity levels to some extent, it may not be as effective as a dedicated dehumidifier, especially in areas with extremely high humidity or larger spaces. Dehumidifiers are specifically designed to remove moisture from the air more efficiently, making them a better choice for tackling persistent humidity issues.

A non-maintained AC is more likely to perform poorly, increase your energy bills, and undergo more severe issues like breakage and water damage. That’s why DIY cleaning or professional maintenance is recommended annually. Otherwise, you might end up paying more in the end than you would for annual service. You can purchase cheap AC cleaning kits if you prefer going the DIY route.

Yes. Return air vents are responsible for gathering and pulling in the warmer air. Once they draw it in, your system conditions the air by removing the warmer molecules from it, allowing your air conditioner to dispense the cooler air back into your home. Not only does this create a more comfortable environment for you, but it also keeps your air conditioner from overworking, resulting in lower energy bills.
