"After getting several estimates both of price and products...we chose Aire Serv. They came recommended by a friend, and it was such a great choice! From the estimate, to the installation, to the office staff, everyone was so knowledgeable and courteous! Dave took the time to see what our homes needs were, and took so much time and patience explaining the hvac system. He was able to solve the problem that I had with the bedroom temp being too high-so easily! Two other contractors offered no solution! We had a complete install done, and Andrew and Will did a great job, even cleaning up every speck before they left! Andrew did such a great caulking job around the work in the wall...I appreciated that! We had one small issue and Joe came right out and fixed it asap! So nice and took great care. Everyone put on booties to walk through the house, and were very careful with our home. I am thankful for a job well done!"

"My heat pump which had been installed 2 years ago by FH Furr suddenly stopped working Sunday afternoon. With the heat warnings in effect, I knew I needed help, FAST! Blair arrived this morning abd diagnosed the issue and replaced the condensation pump. These new "smart" systems have more brains than some humans!! When the pump failed, it shut down the entire system. However, Blair had the old school know-how and work ethic to get my system back online and back to normal. I have seen a nice change in technicians in the last 2 years and am always pleased to have them come out and fix any issues I may have. Keep up the good work!!"

"AirTemp Solutions called me right away on Friday after making initial request on HomeAdvisor. We made an appointment for Monday. On Monday morning I received a call confirming that technician was on the way within 20 minutes. Chris arrived on time, he evaluated the water heater that needed to be replaced, explained what needs to be done and come up with a fair quote. We scheduled installation on Wednesday at 8:00 am. Chris showed up at 8:00 and completed installation and cleaning by 10:00. A pleasure to work with!"

Install Boiler questions, answered by experts

Steam boilers require flushing at least every six to 12 months to keep them operating effectively for as long as possible. Depending on your water quality and frequency of use, you might need to do this more frequently. The flushing process helps to remove problematic buildup of sediments. While a boiler contractor near you can perform a thorough annual flush, learning how to drain the system yourself means you can do this monthly if you experience speedy mineral accumulation because of hard water. 

The absence of heating or hot water, unusual noises like banging or gurgling, and visible water leakage are key signs. Abnormal boiler pressure, flame irregularities (for gas boilers), or pilot light issues may also signal trouble. Frequent cycling, soot or staining, and unusual odors, particularly gas-like smells, should not be ignored. Modern boilers often display error codes or lockout mode upon detecting issues. Uneven heating across radiators and rising energy bills without increased usage can further point to problems. Prompt attention to these signs is essential to prevent further damage and ensure safety.

Professionals can recommend efficient layouts or appliances and ensuring regulatory compliance.

A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.

If you want a new boiler that’s going to help lower your fuel bills, you should buy one that has a high energy-efficiency rating. For example, a boiler that is rated “A” uses at least 90% of the energy created by the boiler. And in order to enjoy the best performance, it’s important to have it installed properly by a highly-rated tech.
