How Often Should I Replace My Air Filter?

It depends on which type of air filter you use. Standard one-inch filters should be replaced every few months, or more often if you have pets, allergies, or someone in your house that smokes. If you use a media or HEPA filter, you can go six months to a year without replacing them or cleaning them. Ask our pros for a recommendation if you’re unsure.

How Often Does My Furnace or Boiler Need Maintenance?

No matter your heating system, you should schedule maintenance every year to ensure a safe and reliable unit. Each year you skip service can cause your system to lose as much as 10 percent of its efficiency. It’s also much more likely to break down and need repairs if it isn’t cleaned or inspected. Investing in maintenance now can help you save on energy bills, avoid premature failure in the future, and keep your manufacturer warranty valid. Ask about our maintenance agreement to ensure you never miss service.

How Can I Reduce My Heating Bill?

Heating bills can rise in a hurry—here are a few ways you can save:

  • Schedule routine maintenance to keep your system clean and running efficiently.
  • Turn your thermostat down one to two degrees and bundle up with extra layers.
  • Adjust your ceiling fan to rotate clockwise—this pushes rising warm air back down toward you.
  • Make sure all vents are open and not blocked by boxes, curtains, or furniture to ensure warm air circulates properly.
  • Open curtains on sunny days to let the sun’s natural heat warm your home.

When Should I Replace My Furnace?

There isn’t a set schedule for when to replace your furnace—most last 15 to 20 years—but there are a few signs you can watch for. These include uneven heating, high energy bills, and strange odors or noises, To be sure, schedule a professional diagnosis, and don’t wait too long because failing systems can be dangerous. If it’s time for replacement, our experts can provide you with a free estimate.

Which Is Better: A Furnace or a Boiler?

Both are great heating options, and each has its pros and cons. If your home has existing ductwork or hydronic piping, a professional will likely recommend that you stick with the system type you already have, as retrofitting can be expensive. In new construction installations, trust our professional techs to make a recommendation that’s right for your home and family’s comfort needs.

Customer Reviews
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.

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.

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

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.

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.

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.

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.
