Carlson Heating, Cooling & HVAC is a company that prides itself in having the highest level of customer care. Our team of Machesney Park HVAC specialists will complete any project with ease. We serve Machesney Park and the surrounding areas. Sorry but we do not work on Boilers or Air Duct Cleaning.

"I’ve used Carlson Heating & Cooling twice and have been very satisfied both times. In 2024, I had them inspect my furnace and AC. They arrived on time, were professional, and gave my system a clean bill of health—without recommending any unnecessary repairs. In 2005, when my AC stopped working, they quickly diagnosed a dead compressor and recommended a replacement. Impressively, they waived the $225 charge for the initial visit and parts. The replacement was completed on schedule, exactly within the estimated cost. The technicians were friendly, informative, and professional throughout the process. They also cleaned up thoroughly, leaving no mess behind. I trust Carlson Heating & Cooling completely and will continue to use them for future service. I highly recommend them to anyone needing a system check-up, repair, or replacement."

"Everyone that we dealt with couldn?t have been nicer. We had a tub to shower conversion which was completed in one day. Matt, the installer, laid a tarp down from the door to our bathroom to protect the floors. He asked for our input when he was installing the shelves and grab bars. After he finished cleaning everything up he explained how to used the new shower head and what to use to clean the surface. The next day we texted him with a question and he immediately answered. We couldn?t be happier with the job done and the professionalism of the company."

Boiler Repair questions, answered by experts

Boiler leaks are the most common problem that impacts this fixture. Some leaks stem from corroded pipes and tanks, while others are due to damaged seals or excessive pressure. No matter how you slice it, boiler leaks are bad news. This issue leads to water damage in the home and malfunctioning electrical components in and around the boiler.

It takes about five to 10 minutes for heat to reach a radiator, then about one hour until the radiator fully heats up a room. The exact duration depends on the size of the room and how far away the radiator is from the boiler heating system. Heating up an entire house could take up to two hours.

If you’re unsure who to call to fix your boiler, you have a few options. One is to call a dedicated boiler service. However, you can also call a plumber or HVAC technician for boiler repair services. These pros will have the tools, knowledge, and experience to fix common boiler problems.

Boilers are equipped with multiple safety features to ensure safe operation. These include pressure relief valves to prevent overpressure, temperature high-limit switches to avoid overheating, and flame failure safety devices in gas boilers to cut off the gas supply if the flame goes out unexpectedly. Low water cutoffs prevent operation with insufficient water levels, and pressure gauges help monitor pressure levels. Ventilation and flue systems prevent the buildup of harmful gasses. Boilers often feature error code systems for automatic shutdown during malfunctions and gas leak detection for safety. Regular maintenance is crucial to ensure these safety features function correctly.

Regular inspections, cleaning, and checking of exhaust systems maintain safe operation, ensuring efficiency.
