"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

A furnace is a big unit where gas, heating oil, or electricity heats the air. The warmed air is then pushed back out through ducts and vents. 

A boiler uses electricity, heating oil, or gas to heat water that is pushed into the room through a radiator. This is one of the oldest and most effective ways to heat a house, but radiators can also be unsightly and leave hot and cold spots in the room.

Heat pumps use a refrigerant to move heat from outside into the house and return it to the room through ducts and vents.

In most cases, repairing a radiator is more affordable than replacing it. A typical repair may cost between $100 and $200, while a replacement can average $1,500, with a range of $250 to $2,500 depending on the unit type. Radiator issues are often simple fixes for a professional, such as a blown fuse, malfunctioning thermostat, or a loose valve, and can take less than an hour. However, if the long-term costs of fixing the radiator are higher than replacement, it's better to get a new model. It is recommended to consult a heating expert to diagnose the problem and determine the best solution for your situation.

Yes, cleaning a boiler is essential for its efficient and safe operation. Over time, boilers can accumulate dirt, rust, sediment, and mineral deposits, reducing efficiency, increasing energy consumption, and causing potential breakdowns. Cleaning involves removing these deposits from various components like heat exchangers, burners, and pipes. Neglecting cleaning can also lead to corrosion and decreased life span. Regular, yearly maintenance, including cleaning, ensures optimal performance, lower energy bills, and a safer heating system. It's best to consult the boiler's manual or hire a professional technician for cleaning to ensure the job is done right.

Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.

To bleed a radiator, first turn off the heat to the system. Then, lay a towel under the valve, open the bleed valve, wait 20 to 30 seconds for air to escape, and gently close the valve. You should repeat this process for every radiator you have in your home. Once your radiator valves have all been closed carefully, you can turn them back on.
