"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

The main difference between an outdoor wood furnace versus an outdoor wood boiler is what each appliance is heating. An outdoor wood furnace burns wood to create heat, which warms the air and moves it through the ducts in your home. An outdoor wood boiler uses the heat from burning wood to warm water, which goes through pipes to radiators in the home.

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

Most home boilers will need an expansion tank. That’s because these boilers are closed-loop systems, where the water is trapped. An expansion tank is needed when the boiler heats the water and it expands, allowing air to condense in the tank to make room for the water. Other types of boilers don’t use an expansion tank, such as traditional steam boilers, but these aren’t as common. And hot water tanks may be able to use a pressure release valve instead. When in doubt, call in a pro to take a look.

Yes, you can build a sunroom addition to your home despite living in a cold climate. Make sure to use high-quality insulation and windows and to supplement with sufficient heating from your HVAC system. The windows in the sunroom allow enough natural light into the room to help heat it most times without having to use the furnace. Even a small electric fireplace can heat the sunroom well enough.

Hydronic and standard electric baseboard heaters differ in how they operate, their cost, and their performance. Standard convection heaters use electric coils to heat the air directly, while hydronic heaters warm a contained liquid like water or oil, which then radiates heat into the room.

In terms of cost and efficiency, hydronic heaters usually have a higher upfront price but are more energy-efficient and cheaper to run over time. This is because the heated liquid retains warmth, allowing the heater to continue providing heat for a while after the thermostat turns it off. In contrast, electric heaters provide heat more quickly but are less efficient.

Ultimately, the better choice depends on your priorities. If you need a room to heat up fast and have a lower initial budget, an electric heater might be suitable. If long-term energy savings are more important and you don't mind a slower heat-up time, a hydronic heater is likely the better option.
