Sure Fire There are few things more important in your home than a properly operating furnace or boiler. Trust Sure-Fire with the service or installation of your heating system so you can "Be Sure" your family stays safe and comfortable all winter long. Air Conditioning is becoming more and more of a necessity, even in Wisconsin's climate. Whether it's for your family's comfort or health reasons, when you need cooling, trust Sure-Fire with the service or installation of your cooling system.

At Sure-Fire, we realize that more goes into a mechanical system than just heating and air-conditioning equipment, and that the lowest cost solution doesn't always represent the best value.
Services
Sure-Fire Inc. is Dodge County's largest heating and air conditioning contractor, founded in 1947 by Emil Malesevich. Our mission then, as it remains today, is to provide only the highest quality heating and air conditioning systems and service to the area. Emil recognized back in 1947, that away from the larger metropolitan areas, finding a knowledgeable heating contractor was next to impossible.
My Home: Are you looking for service or maintenance of your equipment or a free, in-home estimate on new or replacement HVAC equipment?* My Business: Are you looking for service or maintenance of your equipment or a quote on new or replacement HVAC equipment?*
Is your home's heating and cooling system able to keep up with Wisconsin's quick changes in weather? Are there areas of your home that are cooler or warmer than other areas? These are the complaints from many of the customers who hire Sure-Fire as their heating and cooling contractor. HVAC systems are not meant to be a one-size-fits-all solution.
Wisconsin homeowners know that heat plus humidity equals misery, if you don't have a central air conditioning system to draw out the moisture and cool the air. At Sure-Fire, we only recommend and install one brand of air conditioner - Lennox. Lennox has been a leader in heating and cooling equipment for over 100 years.

We had a cracked heat exchanger and needed to replace our furnace ASAP since we were unable to use it due to CO poisoning risk. We called sure-fire and Tom was able to give us a thorough estimate and explained all the furnace options over the phone at 3 PM. By noon the next day, we had a brand new furnace and thermostat installed. The installation guys were friendly, knowledgeable and professional. Thank you, again!

Super prompt service and response time. Our technician was polite, professional, knowledgeable, explained everything and had our AC up in running in about an hour. When it's 92 degrees you're very thankful. I liked the online service request form as our outage happened after hours. We got a call first thing in the morning and all repairs were done by 9am.

Our furnace was out when we came home Saturday night. We called Sure Fire, got answering service. They said we would be called shortly. No one called. I called Sunday morning. I was told by the answering service that if I did not receive a return call in 30 minutes to call back. An hour and a half later, still no call. I called again and finally got a call back.

He came Monday and said we should consider a new furnace and that Tom would call us today about it. Remember, we have no working furnace. As of 4:30PM, no call from Tom or anyone at Sure Fire. I called their office. I got the answering service again.

Very good service. They installed our new furnace and central air last year. They worked quickly and efficiently. Had a check up this year and it went very well. No time at all. Pleasant all around.

Steve has been out to my home for cleanings, both for the furnace and AC. He is very patient when answering all my questions. I always learn something new about my major appliances. He's also very knowledgeable, professional, and wants to do what's in the customers best interest. I would highly recommend Sure Fire to anyone. They are trustworthy and very easy to work with. Thank you!

Sure-Fire provides professional and punctual employees that take their job seriously. Rick came out to my house to make repairs/maintenance on our HVAC and the entire experience was outstanding. No B.S., just upfront honesty. Brian (Manager) and Rick listen to their clients concerns/issues and provide educated remedies to get the job completed at a reasonable price. I highly recommend this company for your HVAC needs.

I have a crawl space to get into my attic. The air conditioning unit is installed in the attic. Needless to say I had two separate problems happen this spring. Sure Fire responded to my request for help. Rob the technician crawled up into the hot attic and fixed the problems. I am sure he was uncomfortable working in those condition. He was courteous, efficient, and fixed the problems with no complaints. I would highly recommend Rob for service on your air conditioner or furnace.

We were told they would arrive at 8. When I left the house at 820, the technician still had not arrived. They called at 840 to say I was not available. When I informed them nobody was there at 820, they stated they were running late. When I informed them doors were unlocked and note explaining how to reach me, they stated they didn't check basement door. Invoice states they left at 1130 but my husband arrived at 1030 and they were leaving. Told my husband never to call them again. Update--Casey called and stated he would discuss customer service with his employees and to contact if technicians are running late. Furnace problem was repaired favorably and satisfied with quality of work.

Difficult to review a company that isn't able to take on new customers with a no heat issue. The service person Dawn seemed nice enough. I was informed that later in the heating season they may be able to do a cleaning. Pros: Honest, scheduler seemed nice. Cons: Not taking me on as a customer.

I have a boiler from the stone ages. It is as big as a sumarine and I am not joking. Surefire has been able to maintain this beast and did an excellent job replacing the pump a few years back. Their fixes reduced our energy bills and with the suggestion of a thermostat we were even able to further reduce our energy costs. No Complaints here.
