"I signed up to have one of my HVAC's covered by Tim Kyle. I used the electrical service for over 20 years and the service is exemplary. This is the first time I used the HVAC service. I was impressed. It was a great job performed by a knowledgeable, pleasant tech who was available to answer any questions I had. Most important the HVAC was up and running before the 100 degree days to come later this week. Thanks guys"

"I contacted Sean to repair my aging HVAC system. Although I have very little knowledge of HVAC, Sean was able to identify, explain, and plan the maintenance of my current system in language I understood and that seemed reasonable. Sean was very responsive via text during our scheduling and I'm happy with the expert level of detail he showed during inspection. I would highly recommend working with him or his team. Update: Sean came back out to resolve my filtration issues and also fixed some other problems that he noticed in the process without increasing the negotiated price. Again, Iâ m extremely satisfied with the work heâ s done and would recommend him for your HVAC needs."

"We got five different work proposals for our HVAC replacement. The person who came to our house was very technically knowledgable. He gave us his cell phone number and gave us plenty of his time answering our questions. I think this contractor would have done an excellent job at a good price."

"The Buric team did a great job of installing two new HVAC systems in our house at a reasonable price.  This is a family run business, the owners of which take pride in their work and pay attention to detai. The Buric team was also able to add zoning our systems, where other contractors had said this would not be possible.  The work was completed in a timely fashion, and the team cleaned up nicely after itself.  We had two babies in the house, and the team took care not to disrupt their sleep schedules."

"If you want honest, straight-forward, complete, and competitive pricing for a new HVAC system, go to Bluestar Air Mechanical. Our 21-year old systems needed replacement and we began our quotation/search process. Amongst the 7 companies we inquired with, Bluestar had the most comprehensive explanation, set of offerings, and was patient with us as we completed our comparisons. John promptly and completely answered all of my questions ranging from installation, future usage, efficiency, and advice on what was necessary vs an accessory. Lynn at the office was prompt and courteous on all of my scheduling, dispatch, and payment inquiries. You'll get top notch quality, service, and friendliness if you work with Bluestar for your HVAC replacement needs."

"From not having a water supply for my whole home bypass humidifier, to having a repaired, new water supply line and instant winter comfort. All in less than two hours. Thanks Edmond and team for getting me taken care of right after I arrived home from work. Wealth of knowledge, too, about HVACs warranties, and other good general advice for first-time homeowners like myself! Glad to have signed-up tonight as a member - eligible for discounts tonight and future maintenance services. Highly recommend!"

Heating and Air Conditioning questions, answered by experts

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. 

Yes, technicians check refrigerant levels, loop performance, and system calibration for peak efficiency.

While Freon is mostly odorless, a Freon leak will produce a faint chloroform-like smell. Some people find that Freon's odor has a subtle sweetness to it. Some telltale signs of a Freon leak beyond odor include ice crystals on your evaporator coil, bubbling sounds, and hissing noises.  

Yes, you can clean your air conditioner filter as a temporary fix for cleaning up dirt, but you’ll eventually need to replace it once the dust starts to accumulate. Use a vacuum with a hose attachment to clean your air filter at least once per year or more often if you have pets.

You can protect your air conditioner in the winter by turning off the power at the thermostat and performing routine HVAC maintenance in the spring. Regular maintenance, cleaning, and repair of your AC unit helps protect it and extend its life span. If you have a window AC unit, remove it from the window and store it in a dry place during the winter. Window units cannot withstand freezing temperatures. Keeping them in your window also allows cold air to seep into your home.
