"Home Comfort Systems did a fantastic job with the replacement of my furnace (and my A/C five years ago). Steve is a highly reputable person and explains things easily for people not in the Heating & A/C industry. He is very straight-forward with his quote and doesn't try to pressure or scare you into purchasing something you do not need. Their 10-year labor warranty is also very impressive, and they stand behind their work. A couple of weeks prior, they were able to take a look at my old furnace right away despite having tons of calls due to the first cold snap of the year. The furnace install only took about three hours and was smooth as can be. The installer took great care in making sure floors were protected when hauling equipment in and out of the house. He also made sure to repair some ductwork that extended off the furnace. My suggestion is to make sure you call Home Comfort Systems if you need service or replacement of your furnace and/or air conditioning."

"The boiler had needed some replacement pipes as well as the solution to the slight smell of gas when near the boiler itself. Prior to calling for service for these issues, I had removed the majority of the damaged piping and purchased all new of what I was able to remove. I couldn't remove the bushing that attaches directly to the boiler or the nipple that attached to that bushing to save my life. On the night prior to the day of my appointment, there was a snow storm and time moved ahead. I had forgotten to move my clocks ahead that resulted in my arriving about 20 minutes late. The repairman was kind enough to not only wait for my arrival, but to shovel part of the snow from my walkway that leads to the basement. This guy is just great. He removed the fused together bushing and nipple in no time flat. It was amazing for me to watch. I had to pick up a couple more pieces of pipe for my job to be completed and we scheduled to continue after I did so. Luckily, The pipe I needed was in stock and he was able to return the very next day, he removed my bushing and nipple, installed ALL of my pipes, and provided and replaced my leaking gas line. MY BUILDING NOW HAS HEAT AND I COULDN'T BE HAPPIER!!! Now I have to have the other parts of the building repaired that were damaged from when the boiler had stopped working and a pipe had burst. You won't be disappointed if you hire Discovery Heating and Cooling. If I have another related job in the future, I will definitely call Discovery. Thanks again Discovery."

"The furnace was making a sound. I called and scheduled repair and or maintenance. The truth I hadn't had the furnace serviced in maybe 4 years I was terrified. They arrived earlier than expected were honest about the problem, charged a fair rate and fixed it. I have heat and thanks to the team at United Heating have learned my lesson I will be scheduling my maintenance in a timely manner."

Boiler Repair FAQs, answered by experts

Yes, it is generally safe and effective to turn off radiators in unused rooms to save money on heating costs. This practice is especially beneficial with older heating systems. However, you should avoid cranking up the thermostats on the remaining radiators to compensate, as this can lead to higher heating bills and increased wear and tear on your system. While some HVAC specialists argue that modern, efficient boilers are designed to heat the entire home and work best when all radiators are on, turning off radiators in unused spaces still reduces the total amount of hot water your system needs to produce.

Oil boilers provide reliable heating, efficiency, and long-term cost savings compared to electric options.

Once you know where your bleed valves are and how to use them, bleeding out heaters is a quick process. Expect it to take around 10 to 20 minutes, possibly longer if you have a lot of heaters or are still learning how they work. If you have a central bleed valve on your boiler, the process still takes the same amount of time. Make sure you have any keys necessary to turn the bleed valves on. Without bleed valves, the process should take around three hours.

Yes, many HVAC professionals offer emergency repair services for furnaces and other heating systems. These services are especially common during the winter and colder seasons when functional heating is crucial.

Air trapped in a heating system can lead to reduced efficiency, uneven heating, increased wear on components, strange noises, and even complete system failure. This trapped air disrupts proper circulation, strains parts, and can cause overheating. Regularly bleeding baseboard heaters and furnaces can prevent these issues, ensuring efficient operation, even heating, and prolonged equipment life.
