When it is time to replace rather than repair

A good rule of thumb is the five thousand rule: multiply the age of the furnace by the repair cost, and if the number tops five thousand dollars, replacement is the better investment. Furnaces older than about twenty years also run far less efficiently than a new high efficiency unit, so the fuel savings help pay for the upgrade.

We install high efficiency gas furnaces rated up to ninety six or more AFUE, and we always right size the unit with a load calculation. An oversized furnace short cycles, wears out early, and heats unevenly, which is the most common mistake we find on homes installed by the lowest bidder.

Our furnace installation and replacement process

  1. Free in home evaluation and a load calculation to size the furnace correctly.
  2. A written quote with efficiency options and financing laid out clearly.
  3. Safe removal and disposal of the old furnace.
  4. Installation of the new unit, gas and electrical connections, venting, and a new thermostat, filed and permitted.
  5. Startup testing for safe combustion, airflow, and a clean walkthrough with you.

What is included

  • Zone by zone comfort planning
  • High efficiency inverter equipment

Serving Bothell and the surrounding area

Snohomish blends historic homes near the downtown antique district with newer construction out toward Clearview and Cathcart. The older housing stock often has aging furnaces and little or no ductwork, which is where heat pumps and ductless systems earn their keep, while newer homes are ready for efficient central systems.

Neighborhoods and areas we serve in and around Snohomish include:

  • Historic Downtown Snohomish
  • Maltby
  • Clearview
  • Three Lakes
  • Cathcart
  • Machias

Mechanical permits in Snohomish run through the City of Snohomish or Snohomish County, and we handle the filing for you.

Seasonality note: Year round. A popular choice for additions, older homes, and rooms that are always too hot or too cold.

How long does a new furnace last?

A well maintained gas furnace lasts about fifteen to twenty years. If yours is in that range and needing repairs, replacement usually costs less over time than repeated fixes.
