"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!"

Boiler Repair FAQs, answered by experts

To extend your HVAC system’s lifespan, it’s crucial to keep up with maintenance. This includes changing filters and thermostat batteries, keeping the outside unit clean and clear of clutter, and lubricating moving parts. Watch out for leaks, mold buildup, and blockages to ensure your unit stays in good working order. Spotting these issues early can be the difference between a simple, wallet-friendly repair and an expensive replacement.

Addressing banging, clanging, and hissing radiators involves several steps. Start by bleeding the radiator to release trapped air, a common source of noise. Next, ensure all valves, brackets, and pipes are securely tightened to prevent the components from rattling. You can also consider installing radiator insulation to dampen heat expansion sounds. If you perform all of these fixes and the noise persists, explore the use of radiator additives that can mitigate water-related noises. If all else fails, you should consult an HVAC professional.

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.

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.
