"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!"

"I was very pleased both times.  It is clear that I am nursing along an old system and it so wonderful to have found someone willing to help me do that.  I know eventually I will need to replace the system but just got through two summers with no problems.  I am so grateful not to have been pushed into believing that I needed to replace the system yet.  Many companies just want to make a sale and are not so willing to help you maintain."

Install Boiler questions, answered by experts

One of the easiest ways to determine which type of furnace will work best for your home is to contact a professional in your area. Many HVAC companies offer free consultations to help potential customers determine if they need a new system and which type would work best for their home and the community’s climate.

Boilers are equipped with multiple safety features to ensure safe operation. These include pressure relief valves to prevent overpressure, temperature high-limit switches to avoid overheating, and flame failure safety devices in gas boilers to cut off the gas supply if the flame goes out unexpectedly. Low water cutoffs prevent operation with insufficient water levels, and pressure gauges help monitor pressure levels. Ventilation and flue systems prevent the buildup of harmful gasses. Boilers often feature error code systems for automatic shutdown during malfunctions and gas leak detection for safety. Regular maintenance is crucial to ensure these safety features function correctly.

Probably not. Moving a boiler to a new location is a very different prospect from replacing it in the same spot, and significantly more expensive. Plus, boilers are typically carefully positioned in proximity to pipes and radiators when installed. Homeowners may want to move boilers to free up space, prevent freezing problems that have happened in winter, or solve a noise issue—but it’s a much more costly proposition.

Scale from hard water is hard to diagnose until it starts causing problems. If your area has particularly hard water, that’s most likely what your boiler is using. If scale build-up becomes a problem, it starts to cause decreased flow and heating, and eventually, valve failures as valves become blocked. Let boiler professionals know if you’re worried about scale and they can offer advice or implement a solution.

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.
