Furnace Repair & Replacement in Issaquah, WA
Cooler temperatures at the base of the Cascade foothills mean Issaquah homes lean on their furnaces for a good chunk of the year, and a system that’s struggling doesn’t usually get better on its own. Mauro Electric Inc. handles furnace repair, tune-ups, and replacement throughout Issaquah, with licensed HVAC technicians who get to the actual cause of the problem.

What We See Most in Issaquah
Ignition problems, worn blower motors, clogged filters, and thermostat issues account for most of the furnace calls we get in Issaquah. We diagnose the specific issue before recommending a fix, and if replacement makes more sense than another repair, we’ll walk you through sizing the right system for your home.
Electrical Expertise Behind Every HVAC Job
Mauro Electric is licensed for both electrical and HVAC work, so when a furnace problem in Issaquah traces back to wiring, a dedicated circuit, or panel capacity, we handle that ourselves rather than looping in a separate contractor.
Furnace Installation and Replacement in Issaquah
When a furnace in an older Issaquah home — particularly near the historic downtown or Olde Town area — has been repaired multiple times or is nearing the end of its expected lifespan, replacement usually saves more money over time than another patch repair. We size every replacement furnace to the specific home rather than matching whatever was there before, since houses in the Issaquah Highlands and other newer developments often have different insulation and layout needs than an older single-story home closer to downtown.
What to Expect from a Furnace Service Visit
We start by inspecting the furnace, thermostat, and related electrical connections to find the actual cause of the problem, not just the symptom. We explain what we found and what a repair or replacement involves before any work starts. Once approved, we complete the work and test heat output and cycling across the home before the job is finished.
