"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."

"Jim did a great job. He quickly assessed the problem and then took our unit with him to work on it more. When he got back to us, the fix would have cost more than it was worth. He gave us options for a new or refurbished PC. We felt the refurbished was a good deal and chose that. He came back and set that up and we are very happy with it. He then took a look at my laptop and again took it along. He tuned it up and installed a speed upgrade we wanted. Of course, we paid extra for the new unit and upgrades, but we thought the price was very fair. Jim seemed very knowledgeable and responsive. We will definitely call him again if we need any computer services."

Install Boiler FAQs, answered by experts

If you hear your radiator clanking even when it’s turned off, it’s typically because there’s trapped water or air in the system, causing a pressure buildup. When you hear significant clanking, popping, crackling, or banging in a radiator that’s turned off, you’ll want to bleed the pipes or call in an HVAC specialist to deal with the problem (and prevent it from happening in the future).

The cost of propane and related services varies depending on tank size and location but generally ranges from $500 to $2,500 for installation and initial fill.

On average, you’ll need about two gallons of oil per day to heat your house when it’s 50 degrees Fahrenheit outside. Most oil tank capacity is about 275 gallons, and heating your house with two gallons of oil per day will last about four and a half months. This consumption will vary depending on the climate and average temperature in your location. For example, if the winters are longer and colder where you live, you’ll probably need to refill your oil tank at least once to get through the winter.

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.

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.
