Size matters more than most people expect with a new furnace. An oversized unit short-cycles, overshoots the thermostat, and wears out early, while a correctly sized furnace runs longer and more quietly and costs less to operate. So Ann Arbor HVAC starts every replacement in Ann Arbor with a load calculation, not the number on the old nameplate. From there, the choices come into focus: 80 percent AFUE or a condensing furnace in the mid-90s, single-stage, two-stage, or modulating burners, and a basic PSC blower or a variable-speed ECM motor that saves electricity and smooths out temperature swings. The best fit depends on your home, your ducts, and how long your heating season lasts, and you will be living with it for the next twenty years.

Warning Signs for Furnace Installation
Catching these issues early helps you avoid costly problems. Here are the most common indicators that it's time to call a professional:
- Paying more to heat a house that never gets comfortable
- Rooms the heat never reaches, wide temperature swings, or constant short cycling
- Your heat exchanger is cracked, taking repair off the table
- The blower is loud enough that you plan conversations around it
- You are pairing a new AC or heat pump and the old furnace is the weak link
- Booming ignition, rust, or soot that keeps coming back after service
- Your existing furnace has passed fifteen to twenty years of service
- Repair bills arriving more often and getting bigger each season
