"During this very cold winter, I wanted my HVAC system checked out, esp after the fan were frozen in place before being de-iced by me. The service person was great. He checked my system and was able to answer my questions. Thank you."

"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!"

"The engineer came out but it took a couple of days. There were some other faults with the problem. It wasn't just necessarily a tune-up problem. He found some other things wrong and basically addressed that as well. They got in contact with me quickly. For the deal, there were no additional charges but there were some other things wrong with the heating and air conditioning unit that needed to be addressed that were outside of what was covered. I was okay with that. Everything's working fine now. He needed additional parts. He completed the job in three days."

"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."

"Excellent job. Hired to remove old thermostat and replace with new Nest thermostat. After installation, he tested the new thermostat to make sure that it was working properly. Very courteous. Also requested that he assist in locating and changing air filter. He located, removed, cleaned and replaced with no extra charge. Would definitely recommend for future work."

Install Boiler FAQs, answered by experts

The radiators closest in proximity to the boiler heating system will heat up first. Radiators in rooms farther away from the boiler will take longer to heat up and may be the coolest rooms in the house. The radiator unit itself should heat up evenly; otherwise, there may be trapped air inside it.

Some high-quality steam boilers come with 10-year warranties, but a well-installed, properly maintained model can last at least 20 to 25 years. Learning how to clean a boiler, getting an annual professional service, and keeping up with maintenance and repairs on your heating system are all important for getting the most out of your model. 

Yes, most municipalities require a permit for propane boiler installation to ensure safety and code compliance. Permit fees vary by location and are often included in your installer’s quote, as they’ll handle the permitting process. Ensure that you always check local regulations before starting your project to avoid fines or delays.

Costs depend on unit size, labor, fuel type, and whether additional piping or venting is needed.

Generally, an oil furnace is considered safer than a gas furnace for several reasons. While both types of furnaces can produce carbon monoxide, a leak in an oil furnace is easier to detect due to the smell. Oil furnaces also don't connect to a gas pipeline, which reduces the chance of a fuel leak. Most importantly, heating oil is not combustible, whereas natural gas is highly flammable. This means there is a much lower risk of combustion or explosion with an oil furnace. However, an oil furnace can still pose a fire hazard if it tips over.
