"Harker Heating And Cooling is the best HVAC contractor we have ever worked with in 40 years. Their web site proudly says they are an “honest company with Midwestern values.” That is absolutely true. Their representative provided in-depth advice, answered our questions. and returned our messages. Their techs were knowledgeable, professional, careful, and friendly. They were on time, on call, and on budget. The service they provided for us over the years could not be better. So when the time finally came to replace our old furnace and A/C we selected them. Unfortunately, they encountered many unexpected problems installing our new equipment. Many more than they had anticipated for the job. But their representative pledged to address every one of them no matter how hard it was for them or how much of their time it took. And that is exactly what they did. No quibbling and no questions. They got the job done right. If you want an honest family contractor who stands behind what they do, and lives by those Midwestern values, then this is the company to hire. You will be glad you did.

"I had lost heat to my boiler late one night in February. With my family gathered around our fireplace in the living room & heat dropping on one of the coldest nights of the year, I was concerned. JB Mechanical responded first thing in the morning. The technician did a nice job of diagnosing the problem. After a few hours we had our boiler up in running. They also worked with me on the price, adjusting accordingly. A job well done by Patrick, the technician."

"We found everything and everyone to be very efficient and pleasant. There was one glitch, however, when the electrician didn't turn on the fuprnace before he left Everyone was very apologetic and things were rectified very quickly. Also, there was a loud banging noise when the furnace turned off. This also was rectified very quickly. The serviceman was very apologetic"

"Awesome! We have never felt more comfortable and satisfied hiring a contractor! Brian came out within a day or two to look over the project, and then within another few days had a written quote! This was a huge project, and they handled it like no one else could. We interviewed 3 other companies and hands down, chose Arctic Air. Within a weeks time, they had removed 2- 250 gallon oil tanks, filled with oil mind you, took out the old oil furnace, replaced with a new gas furnace, and installed air conditioning! Not an easy task on a 125 year old home! Will definitely recommend to everyone!"

"Jim is local.  It went great. Jim Ferrell is a professional of the highest caliber. Responded quickly, took care of my problems, and advised me as to better means of protection than I had. He came back a second time to uninstall software that I purchased that did not provide adequate protections and installed free software that would do the job.  He did the work through remote connection, but is available on site if necessary.
For those people needing help on getting red of malware, viruses , etc. on your computer,  Jim is local, better than all thse remote out of state location providers, is a mature, highly trained professional in this area.
If you go to local computer stores you get very young people that can do a basic job, but are no where near the professional level of Jim.
I highly recommend Jim to anyone that needs these type services.

Install Boiler questions, answered by experts

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.

A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.

If you go to turn it counterclockwise and it won’t turn anymore, it’s open. Like most other valves, you should be able to turn a radiator valve counterclockwise (to the left) to open it and clockwise (right) to close it. To close a radiator valve, turn it clockwise until you meet some resistance and can’t turn anymore, but do so carefully to avoid breaking the valve.

Heat pumps are significantly more efficient than boilers, typically providing three to four times the amount of heat for the electricity they consume. While boilers run on fossil fuels, heat pumps use only electricity. This efficiency can lead to long-term savings on operating and maintenance costs. However, heat pumps have a higher upfront installation price compared to boilers. Despite their lower efficiency, boilers remain a popular choice for many homeowners, with 8 million in the United States alone, due to their lower initial cost and less intensive installation process. Ultimately, the best choice depends on your home's infrastructure, your budget, and your personal heating priorities.

An HVAC system typically lasts between 10 and 30 years, with an average lifespan of 15 to 25 years. The longevity of the system is influenced by factors such as the quality of the unit, usage frequency, local climate, and how well it is maintained. Regular maintenance, including cleaning, filter replacements, and professional inspections, can help maximize its lifespan. Different components within the system have varying life expectancies. For example:

  • Furnaces: 15 to 30 years

  • Boilers: 20 to 35 years

  • Air Conditioners (AC units): 12 to 20 years

  • Heat Pumps: 10 to 20 years

  • Ductless Mini-Splits: 10 to 30 years
