Carlson Heating And Cooling
Carlson Heating And Cooling
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."

FAQs for boiler repair projects in Belvidere, IL
The average cost to install a new water heater is around $1,300, but you can expect to pay between $875 and $1,750, depending on the kind of water heater, the size of the unit, and the professional chosen to complete the work. Tankless water heaters can push your price higher, as installation is more complicated, with prices as high as $3,500. The location and accessibility of your water heater will play a role in the project cost, as those sitting in tight spaces like a crawl space will drive up your labor costs.

It is very difficult and dangerous to install your own water heater, so we strongly recommend against tackling this as a DIY project. Not only will you need to wire your water heater, but you’ll also need to connect plumbing to the intake and outlet. Sweating copper pipes and connecting wiring properly are skills most DIYers don’t have, and even if you do feel confident you can do it, working with water and electricity always leaves the potential for electrocution. Hiring a local water heater installer is well worth the investment.
The average cost to hire a plumber is around $100 an hour but can vary between $45 and $200 an hour depending on the plumber’s experience and the repair that you need. It’s also important to note that these prices can go up on holidays, and emergency plumber rates average $150 per hour, in addition to a flat-rate trip fee of $100 to $350.
