"These guys rocked, from the time I called on a Friday, to the install of our brand new furnace the following Tuesday! Technician-Scott and Ryan were prompt, friendly, informative and professional. The quote/estimate given was fair/reasonable and in the end was what we paid. Installers-Oscar and Kevin were prompt, friendly, informative, professional, quick and did an outstanding job. Thank you to everyone at Elevated Comfort for your great service! I would definitely recommend them to anyone needing HVAC work to be done!"

"Service plumber arrived on site, on time and was ready to begin. He was friendly and professional. He was fully aware of the problem and what needed to be done. He acquired the necessary parts and changed them accordingly as proficient as possible. Our bathroom sink drain issue was completely resolved and ready. Thank you Eric for a great job!"

"This is a family owned small business. They are friendly, professional, punctual, and really know their stuff. All at a very fair price. My AC had been getting worse every year until last year. HVAC Utor came out and fixed it. It ran better than ever before. This year it was just blowing air so I called again. Same great service as last year. Rachel kept me informed so I knew when they would be here. The problem turned out to be the new thermostat I had installed a couple of months ago. Diego had it figured out and fixed in 15 minutes. I can't say enough good about this company and the people who run it. They're the best!"

"The team of four was very professional and performed an excellent job in a record period of time. Just one day to take the old furnace away, replace all the old boots and duct work and install the new furnace. They paid a lot of attention not to damage or dirty the floor/carpet. I am very happy with their performance. They may not be the cheapest on the block but it was all worthed and you only have to do that once in your lifetime."

Boiler Repair 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.

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.

It can be difficult to determine the cause of a coolant leak unless you have the unit inspected by a certified professional. Most coolant leaks are caused by wear and tear on seals and joints. This typically happens five years after a unit is installed. Additionally, faulty or worn compressors, evaporator coils, and condenser coils can also cause leaks.

DIY troubleshooting is possible for minor issues like bleeding radiators or resetting the system, but professionals should handle complex repairs to ensure safety and efficiency.

Your house may be cold even if the heat is on because of bad insulation, gaps in doors, small holes pulling hot air from the home, or excess humidity. The heater itself might be malfunctioning. For this problem, you’d need to talk to an HVAC pro. If you have a gas heating system (most do) this should be considered an urgent job as natural gas could be leaking in your home.
