"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."

"The install took longer than expected because they are a small company, and were extra busy with other jobs that week. However, when it was all said and done, I am quite pleased with the results. The AC works great in the summer, and my winter heating bills are almost 50% less than they used to be. Would I do it again? Yes. Would I wait this long to do it? No Way! One of the main reasons Bob's company is special is that he does a good portion of the work himself. It's not contracted out to people you don't know. You meet Bob, and he does the work. Bob was also very accommodating about where to place vents, how to route ducts, etc... He also did a good job at educating me on how the system works along the way. Thanks Bob!"

"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!"

"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

If refrigerant levels are low, it can cause the evaporator coil to freeze up. Low freon causes a drop in pressure, which will make the coil too cold and cause moisture to freeze on the coil. Your system may be low on refrigerant because of a leak. 

Make sure to have maintenance performed twice a year, and contact your local HVAC technician if you suspect your system has low freon levels.

In most cases, you should hire a professional to carry out services on your HVAC system, as the components are complicated, expensive, and potentially dangerous to work with. However, there are a few things you can do on your own to keep your HVAC system in good condition, including changing your filters every three months, keeping the area around your outdoor condenser clear of debris and plant growth, making sure your or intakes aren’t blocked, and keeping an eye out for increased energy bills, strange noises, and unusual odors related to your equipment.

A dirty AC filter can lower the efficiency of your system, so depending on how dirty it was, you may notice a temperature difference when you clean your filter. You can try other solutions if your AC isn’t blowing as cold as it used to. You can call in a local HVAC tech to make sure everything is running correctly, fix your air seal if it’s a window unit, and clean your coils.

A window AC unit is not completely silent. You’ll hear the sound of air blowing, and if you put your ear right up next to the unit, you may hear a slight hiss or gurgle as the refrigerant flows through the system. That said, if your system is making a running water sound, a loud banging sound, a grinding sound, or physically vibrating, you may be facing an issue or malfunction with your AC unit.

No, it isn’t necessarily bad to turn your AC on and off frequently—contrary to popular belief. Even if you stop and start your AC throughout the day, it won’t use as much energy as it would if you ran it nonstop. 

If you’re concerned about your power consumption and energy costs, there are a few simple ways to use your AC more efficiently. Regularly cleaning the filters, scheduling routine maintenance, and using a programmable thermostat are all great choices.
