Replacing a furnace is one of the few home decisions you make for the next two decades, and the choices stack up quickly: an 80 percent AFUE unit or a condensing model in the mid-90s, single-stage, two-stage, or modulating burners, a conventional PSC blower or a variable-speed ECM motor that sips electricity and smooths out temperature swings. The honest answer is that the right combination depends on your Reston, VA home, how long your heating season runs, and how your duct system behaves, which is why Reston HVAC starts with a load calculation instead of copying the BTU rating off the old unit. Oversized furnaces short-cycle, overshoot, and wear themselves out delivering comfort in lurches; correctly sized ones run longer, quieter, and cheaper.

Warning Signs for Furnace Installation
Recognizing the warning signs early can save you time and money. These are the signals our technicians see most often:
- The furnace you have is fifteen to twenty years old or more
- Repair bills arriving more often and getting bigger each season
- Your heat exchanger is cracked, taking repair off the table
- Uneven heat, frequent cycling, or rooms that stay cold no matter what
- Rising energy bills and a home that still feels chilly
- A blower so noisy you have to raise your voice when it runs
- Booming ignition, rust, or soot that keeps coming back after service
- You are upgrading your cooling system and the aging furnace would hold it back
Act Before It Gets Worse
A failing capacitor, clogged condensate drain, or dirty flame sensor rarely fixes itself and usually gets more expensive to address the longer it runs. Call (571) 741-3122 at the first sign of trouble.
