Your equipment works hard, especially during the long, cold winter months. Heating problems can happen, but nobody wants to lose heat in the middle of a cold snap.

That’s why it’s so important to have your heating system checked every year.

A yearly heating checkup diagnoses any potential problems with your heat pump, boiler, and furnace. Preventative maintenance helps your system last longer, and prevents problems when you need heat the most.

I needed a new furnace and Minnick’s was very helpful. They helped fix the floor in my mechanical room. The technicians were professional and knowledgeable. I had technicians from other companies out and they didn’t do as good a job as Minnick’s.
