Call a professional. Through various means of wear and tear, your furnace will eventually need maintenance. We'll diagnose your heating unit and let you know if a repair is necessary or if a replacement is needed.

We recommend servicing your HVAC system at least once a year — ideally a heating tune-up in fall and an AC tune-up in spring. Regular maintenance prevents breakdowns, improves efficiency, and extends equipment life.

System size depends on your home's square footage, insulation, windows, and other factors. An oversized or undersized system wastes energy and reduces comfort. We provide free in-home assessments to recommend the right size.

Most HVAC systems last 15-20 years with proper maintenance. If your system is over 15 years old, is needing frequent repairs, or your energy bills are rising, it may be time to consider a replacement.
