"Our central air conditioner stopped running, and I called Sharp-Long because they had originally installed the system and had periodically provided maintenance on it in the past. The owner, J.C. Crossley, went out of his way to send a service employee to look at the problem within an hour (it was at the end of the day).  The employee, who was very friendly, courteous and knowledgeable, determined that the coolant had all leaked out, re-charged the system with recycled coolant for free and ran tests preliminary to determining whether we could claim a utility rebate when we replaced the system.  I was extremely grateful for the courtesy extended by Mr. Crossley and strongly considered his bid for replacement, but in the end we did select another bidder. I offered to pay Mr. Crossley for the service call, but he declined the offer.

"I had a problem with a new room which we had added onto the house. The water pipes going out into this room had frozen twice. Called a plumber who recommended we call someone trained in insulation work. Called Insulation Pro's who came out the very next day and after crawling down and into the new space knew right away what the problem was. Problem was caused by a poor job insulating the room that the building contractor had insulated himself. Insulation Pro's had a team of workers come out the very next day and re-insulated the failing area. No problems since and I would recommend these folks to anyone needing insulation services. They were great!"

"I called Tap Heating and Cooling early Sunday afternoon.  John was at the house within an hour.  He explained to me what the problem was and how it could be fixed.  He left to go get parts and was back within the hour like he said.  He assured me he wasn't leaving until I had heat.  When he left I had heat.  Thank you John.  In the future Tap has won my business.  Nothing but professionalism, honesty, and courteousness was shown.  Great customer service.  You will be hearing from me in the near future.

Boiler Repair FAQs, answered by experts

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.

An expansion tank must always be installed on the supply side, which is the side where the boiler sends water out to heat the systems. That placement allows the water to push against the air and condense properly as it is heated, then circulated through the system. Professional installers can recommend the best place on the supply side for an expansion tank.

One of the most common signs you’re dealing with a bad thermocouple is the pilot light for the water heater will continuously go out. For example, you may light the pilot light and then have to re-light it a few days later. You can also look at the thermocouple for a visual inspection. If you notice discoloration, cracks, holes, or other damage, then you know it needs replacing.

Radiators are a popular home heating choice in older homes, but they are becoming less common in new-construction homes. According to a 2022 report by Elements Visual Capitalist, only around 1.3% of new single-family homes have radiators and similar heating systems, such as baseboard heating.

While they may not be as popular as they once were, radiators today come with more energy-efficient features that can make them practical for modern homeowners.

If your radiator turns on every time you turn on your hot water, your problem is likely your motorized three-port valve that’s attached to your boiler. When it malfunctions, the valve isn’t closing properly, so the water begins to flow to your radiator, thus kicking off the heat. To fix this, hire a boiler repair tech near you to replace your valve.
