"I'm super glad I took advantage of this offer. James Hayden came out to my house and did a thorough inspection on my furnace that was probably from 1970. He had the tools and equipment to be thorough, and I found him super knowledgeable and friendly. James found very high CO levels in my exhaust and recommended that I not run the system until we got this resolved. For the safety of my family, I'm so glad he had the tool to measure CO levels, and that he identified the safety problem."

"Fair service on my furnace. The thing I am concerned is I was overcharged with the Thermostat they installed. I paid $145.00 for a thermostat costing $85.00. I checked price from other businesses to see how much the same Thermostat cost. Also, found out after they left that the name of their business is inscribed in the thermostat they installed. It should even be discounted since they are using the thermostat to advertise their business. This is taking advantage of innocent people like me. Won't use them again."

"I hired Comfort Energy to replace my moms heater after reading excellent reviews. The reviews were spot on! Eddie, the customer rep, and Nima, the installer was knowledgeable, straightforward forward and professional. Nima did an excellent installation, followed Covid protocols, and did clean up afterwards. We could not be happier!"

"Had a wonderful experience when Joaquin, Ben and Anthony of ABC Cooling, Heating & Plumbing came out to install my mini-split heat pump unit this week. Professional, respectful, skilled at their craft, and with attention to detail. They communicated clearly, kept mess to a minimum, and cleaned up thoroughly after themselves. Highly recommended!"

Install Boiler questions, answered by experts

Common problems include leaks, low pressure, and inefficient heating. Regular maintenance prevents many issues.

You can use a boiler and a furnace, although it’s not common to use both for whole-house heating. For example, your furnace may take care of HVAC heating through your vents, while a boiler powers your floor-based radiant heating in the bathrooms. Mixing and matching like this gives homeowners a variety of heating possibilities.

If you go to turn it counterclockwise and it won’t turn anymore, it’s open. Like most other valves, you should be able to turn a radiator valve counterclockwise (to the left) to open it and clockwise (right) to close it. To close a radiator valve, turn it clockwise until you meet some resistance and can’t turn anymore, but do so carefully to avoid breaking the valve.

No, boilers and water heaters are not interchangeable because they serve different primary functions. Boilers are used for central heating systems, providing hot water or steam to heat your home. In contrast, a water heater's purpose is to supply hot water for daily household use, such as for faucets and showers. A water heater alone cannot supply the warm water or steam needed for a central heating system.

While they are not interchangeable, it is common to have both a boiler and a water heater. In fact, a conventional boiler often works best when a water heater system is already in place. The two systems can be combined to provide both heating and hot water, either by pairing a boiler with an indirect water heater or by installing a premade combination boiler-water heater unit. For home heating, some homeowners may also opt for a furnace instead of a boiler.

The most important sign of a boiler problem is something happening unexpectedly, which is why regular boiler maintenance is important. Unexpected problems can include strange smells, new leaks, and unexpected noises that your boiler wasn’t making before. Additionally, if a boiler keeps shutting off or can’t maintain a specific temperature range, it’s time to call in an expert.
