A Precise Home Furnace Installation Makes All the Difference

If your system isn’t working as well as it used to, is more than 15 years old, or constantly needs repairs, it may be furnace installation time in your home. A new, highly efficient unit can make a substantial difference in both your home comfort and your energy bills.

However, that system won’t perform as well without a perfect installation—which is where Air Tech Heating comes in. Our knowledgeable furnace installers will assess your current unit, accurately measure your space to find the best size system, and lay out your options. That way, you can make an educated decision that fits your lifestyle and budget. Once we’re ready to install, we can even custom-fabricate ductwork for a seamless fit and improved efficiency.

Questions about the cost? Seasonal promotions are available to help ease the burden of buying a new system. We also offer special financing, subject to credit approval.

A New Furnace Deserves Proper Maintenance

Like your car or any other machine, a furnace needs routine maintenance to work as safely and efficiently as possible. Preparing your system with a thorough cleaning and a new air filter before winter hits will help it keep up with frigid temperatures and reduce the need for repairs.

Our maintenance agreement makes it easy to keep up with annual service—and you’ll get benefits like priority service, discounts, free filters, and more.

Customer Reviews
Steve Kin

I am so happy with the work and the installers. They were here when they said, promptly got working on taking out my 36 year old furnace, all of them were kind and courteous as well. Once the new furnace was installed they showed me how to operate my new thermostat and how the furnace itself worked. I am very pleased with how it is heating my house. I would recommend them to anyone.

Sue Schommer

AirTech was very quick to take care of us. Jon was very courteous and knowledgeable and took the time to explain the problem to us. We had an excellent experience with AirTech and will continue to call on them for any future needs, and highly recommend them to others.

Tammy Wiese

Called at night after hours. It was not an emergency for us. Was told they would call in morning – received a call as promised and was scheduled during a specific time – technician had problems with other calls and was later than expected time – office and technician apologized for the inconvenience- very respectful of our time – always provide best service

Colonel Joseph

I have been getting my AC and Heat serviced every year by Air Tech Heating for a few years now and could not be more happy. My furnace had a major issue several times and they never tried to upsell me into getting a new one. They just offered it as an option. I wish I had taken them up on this sooner but it took until this year to replace my system. They arrived on time the morning of 11/27 and did an excellent job on the install and clean up. They took the time to answer all my questions and left my house the same or better then when they arrived. Very trustworthy, respectful and professional crew.
Thank you Air Tech Heating and see you again during my next PM service.

Diane Lechner

Jon Jahn serviced our furnace and changed the needed filter. He provided excellent service and was very professional. I would definitely recommend Air Tech Heating to anyone needing a new heating/air conditioner or service.

Michael Nanna

Of course our old air conditioning unit stopped working on one of the hottest days so far this summer. Air Tech Heating immediately jumped thru hoops to replace our air conditioner with a new Bryant unit. They are so wonderful to work with and are a top tier company with the best products. Are new unit is so quiet and so much more efficient!! Can’t wait to see my next power bill. Give them a try. You won’t regret it.

Lori Borth

I have been using Air Tech Heating for about 10yrs. The office personnel are always friendly and helpful. The technicians are always professional, polite and arrive within the timeframe scheduled. I am so confident in this company that I am purchasing a new furnace from them. I highly recommend this company.
