To keep your system running at peak performance, we recommend professional maintenance twice a year: once in the Spring for your Air Conditioner and once in the Fall for your Furnace. Regular tune-ups ensure your equipment is running safely & efficiently, help prevent unexpected breakdowns during Michigan’s extreme temperature swings, and can extend the lifespan of your equipment by years.

You should call a professional if you notice unusual noises (banging, whistling, or grinding), inconsistent temperatures between rooms, a sudden spike in your energy bills, or if your system is turning on and off frequently. If your A/C is blowing warm air or your furnace is blowing cool air, it’s time for a diagnostic visit.

Yes! We know that heating & cooling emergencies don’t always happen during business hours. Whether your furnace quits on a freezing Winter night or your A/C dies during a Summer heatwave, S. Finzel Mechanical offers prompt emergency service to keep your family safe and comfortable.
