"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."

"I had an issue with my computer where it was opening lots of pop ups, ad bars, and windows with ads for games. I had tried several different programs to try to remove it with no luck. I finally decided to call North Alabama Technical Service to see if I he could help. I was expecting to set up a time for him to look at it but he connected to my computer immediately and within an hour had it fixed and running perfect again. Great service at a great price and I didn't even have to disconnect it and carry it somewhere! Would call again if I have another issue I can't resolve myself."

"Install went great. We were very well taken care of. Jeremy and Dylan took excellent care of us and went above and beyond to make sure our furnace was in working order. I will recommend them to anyone I know seeking HVAC or electrical work."

Install Boiler questions, answered by experts

Using heating oil to heat your home has its advantages, but it also has its disadvantages. 

Consider these drawbacks before installing a heating oil system:

  • Heating oil prices fluctuate frequently

  • Risk of oil spills or leaks

  • Produces more air pollution and soot compared to a gas furnace

  • Regular maintenance required for equipment

  • Need to reorder heating oil consistently to avoid running out

The average cost to replace or install a new HVAC system is around $7,500. However, the price can range from $5,000 to $12,500, depending on factors like the size of your home, the type and brand of the unit, and your specific heating and cooling needs. If you only need to replace certain components, the cost will be lower; for example, a new AC unit can cost between $2,200 and $5,500, while a new furnace costs $3,200 to $6,000. If additional work like new ductwork is required, the total cost could be as high as $22,000. It's best to contact a local HVAC company for an accurate quote.

Oil boilers provide reliable heating, efficiency, and long-term cost savings compared to electric options.

Most propane boilers last 15 to 20 years with regular maintenance and proper care. The lifespan depends on the quality of the unit, proper installation, and the level of maintenance. Investing in annual service can maximize longevity and efficiency. Routine inspections and timely repairs prevent early breakdown, ensuring your boiler heats your home for years to come.

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.
