Furnace Maintenance

The maintenance of your furnace is vital to keeping it running smoothly and efficiently year-round. You don’t want to be in the situation of having no heat in the middle of winter or facing a costly emergency repair because routine maintenance was missed. If you just moved into a new home or you’re ready to get an old furnace back on track with regular maintenance, give Black-Haak Heating a call at (920) 750-7138.

The furnace technicians at Black-Haak regularly work with local homeowners in Appleton, Neenah, Menasha, Darboy, Kimberly, Kaukauna and Greenville to keep their furnaces up and running year–round. That means annual maintenance, completing minor repairs, and replacing parts when needed.


Furnace Maintenance by the Homeowner

While regular maintenance of your furnace by a trained furnace technician is important, there are a number of things you can do to help keep it running properly. For instance, you should always keep a close eye on the operation of your furnace. How efficiently is it heating your home, are there any spikes in your energy bills and are there are funny smells or sounds coming from the furnace are just a few questions you should ask yourself from time to time. These are all signs that your furnace may require maintenance by a trained professional, but being aware of such issues can help you avoid costly future repair work.

Additionally, always keep your furnace room clean and organized. We see dust and debris buildup, as well as standing water from time to time, which can be dangerous for your furnace, exhaust and venting. While a trained technician should clean your ductwork every year with commercial equipment, you can help with monthly cleaning of reachable vents. A vacuum cleaner hose attachment used on room vents and the main fan of your furnace can help remove large debris and dust accumulations before they have a chance to build up. Taking these preventive steps can help avoid unnecessary breakdowns which may help extend the life of your furnace and make our work faster to complete.


Furnace Maintenance by an Expert Furnace Technician

While there are a lot of self-checks and steps you can perform on your own, eventually a furnace technician is needed to take more direct action. Annual maintenance on your furnace depends partially on the type of furnace you have in your home. For example, electric furnaces are less maintenance intensive because they don’t use combustible fuels. A newer electric furnace model may only require service once every 2–3 years instead of once per year. The cost of running an electric furnace will often outweigh the benefit of fewer maintenance visits, but it’s still a nice benefit. For gas and oil furnaces, however, your service professional will need to check the flue and all vents, maintain the gas and oil lines, check for any parts that need replacement and do a workup of the furnace’s efficiency to make sure nothing has been compromised. Additionally, because furnaces use a forced air system to transfer heat throughout your home, the ductwork that transfers that heat must be annually cleaned and inspected for breaks or tears between duct joints.

Whether you just had a new furnace installed and want to get on a regular maintenance plan, or you have decided it’s time to restart your existing maintenance plan, contact Black-Haak today and learn how our Fox Valley area furnace maintenance technicians can help you keep any brand of furnace running for years to come.

It doesn’t matter if you just bought a new home or are looking to get on track with routine maintenance – our team of expert furnace technicians are ready to help you get started no matter the brand of furnace you have!

Our Reviews

I live in Tennessee and my 90 year old mother lives in Appleton. She was having issues with her electrical. I had Black-Haak service the electrical panel and repair 2 switches in the bedrooms. I was extremely impressed with the professionalism of Mike and his helper Isaiah. My mom felt very comfortable and respected. We were informed when, and who was coming with a picture of Mike for identification before he arrived. The office personnel was polite and helpful setting up the appointment and had excellent follow through. Thanks so much for your great service!Pamela Allar

We had a problem with our a/c on a Sunday afternoon and called Black-Haak. They had a service tech here within an hour and they had our a/c back up and running in no time. Our tech was very knowledgeable and Black-Haak provided information on what precautions they are taking related to Covid-19. We highly recommend Black-Haak.

They did cancel one appointment which caused some inconveinance on my end. Other than that I was very pleased with them. The electrician was very nice and did a good job, going above and beyond to make sure things were right and complete. They followed up to make sure all was good.

Black-Haak was great to work with. They were able to schedule an appointment within days and I had an estimate within hours. They have great communication. I received a text with the name and photo of my technician Mike. Mike and his crew were here for most of the day working. They showed up on time and took care of everything. What impressed me most was how Mike and his crew interacted with my family. They were kind and patient with my pets and my kids. Thanks Mike!

Our air conditioner died on a Saturday during one of the hottest weeks of summer. I called Black-Haak in Sunday, they got an estimator out on Monday morning, and I had a new A/C installation scheduled for Tuesday. Then, on Monday afternoon they called and said they had an opening and could get the new A/C installed that day! They got the new unit installed, and their techs stayed even longer to fix a shorted out wire connecting my smart thermostat to the new unit. The experience overall was excellent - very professional, responsive, quick, efficient service all around.

Service was good but my only concern was scheduling. Had to be changed to a later date and the day of service, tech arrived 15 min late. The office called and alerted us so that was helpful. I'm wondering if you prepay for the ac tune up when you pay for the furnace tune up in fall that kind of puts you as a lesser priority to get on the schedule.

From Rick at the time of the estimate to Devin and Jeremy and the others at install, top notch service! They were not the cheapest estimate but were in line with their competition. The information and service were the reason we chose Black Haak for our central air and we have no regrets. Thanks a million guys! Job well done.

Jamie has been great in reviewing options for replacing our furnace. The technician identified an issue with our fan and given the age of our system, recommended replacing. Jamie arrived within 30 mins of the technician leaving and reviewed options with us for replacement and provided a quote for a new system.

Anytime I call for a heating/cooling question/issue, I get an immediate response. Non-emergency issues are usually addressed within a day or two and any type of emergency is handled immediately!! Wonderful company. Awesome, friendly employees. SO glad they were recommended to us a couple of years ago. I wouldn’t go anywhere else!’

They were able to get me in early and called to let me know - appreciated. The technician, Dan, was wonderful. He was very friendly, knowledgeable, loved my cat (bonus points) and patiently answered all my questions. I would 100% recommend both him and Black-Haak Heating to others!
