"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.

"Very prefessional and thorough. Left my place clean after the install, and even loaned me some goo-be-gone from their toolbox for a project that I was working on while they were installing my furnace. They reviewed what they did at the end, and gave me a card so that I could call with any issues. Would highly recommend Sears and their contractors."

"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!"

Install Boiler FAQs, answered by experts

The cost-efficiency of baseboard heaters depends on the type and how you use them. Generally, standard electric baseboard heaters can be expensive to run because they use electric resistance heating, which is less energy-efficient than systems like forced-air or heat pumps. However, hydronic and gas versions are typically much cheaper to operate. Hydronic models are more energy-efficient because they heat a liquid that retains warmth longer, preventing the thermostat from turning on and off as often. The overall running cost is also influenced by local electricity rates, your home's insulation, and your usage habits. To increase efficiency, you can use baseboard heaters for zoning, meaning you only heat the specific rooms you are using.

Since your boiler keeps you warm and provides hot water to your home, you’re likely to notice issues with heating in your living space right away. The most obvious sign that your boiler is breaking is not getting any heat or hot water. You might also hear some odd sounds coming from your boiler during operation, the flame in your gas boiler is not blue, the pressure is inconsistent, or your boiler is using more energy than it should. If you notice any of these signs, be sure to call a pro right away.

Chilled water HVAC systems use water instead of traditional components and refrigerants. They're more common in commercial settings than residential ones but are slowly being adopted by some homebuilders to cool homes. As the name implies, the system keeps the water chilled at 40 degrees and circulates it through water coils. The water absorbs the heat from your home and drains outdoors. Condo apartments are more likely to have chilled water HVAC than single-family homes because this system is designed to cool several rooms or large areas individually.

All modern boilers are condensing boilers because they’re the most efficient type. Instead of extra heat leaving through the flue, these boilers trap the heat and use it to heat the house. Whether you choose a combi boiler, system boiler, or regular boiler, you can opt to get a condensing system. If you have an old boiler that’s not a condensing boiler, it’s a good idea to get an upgrade.

The cost of propane and related services varies depending on tank size and location but generally ranges from $500 to $2,500 for installation and initial fill.
