How do I know whether to repair or replace my furnace?
Age, the cost of the failed part, and safety drive it. A cracked heat exchanger or a failed control board on a twenty-year-old unit usually points to replacement. We give you both options with the numbers and let you decide.
How long does a furnace installation take?
Most straight swaps in a similar location run one day. Adding venting changes, moving the unit, reworking a plenum, or upgrading gas or electrical supply can push it into a second day. We tell you which before we start.
Will you size the new furnace or just match what is there?
We measure and calculate. Matching the old nameplate repeats whatever mistake the last installer made, and oversized furnaces short cycle and leave rooms uneven. Sizing accounts for square footage, insulation, windows, and how your ducts actually run.
Is a high-efficiency furnace worth the upgrade?
Often yes, though it depends on your ducts, venting route, and how much heating you actually use. High-efficiency units need a condensate drain and different venting, so we check whether your house supports it before recommending one.
How soon can you get to a Mountlake Terrace home?
Call us and we will give you a real window rather than a guess. Most Mountlake Terrace calls are scheduled within a few days, and no-heat or no-cooling situations move up the list. Before we arrive you can check the thermostat batteries and settings, look for a tripped breaker, swap a dirty filter, make sure supply vents are open, and clear leaves or blackberry growth away from the outdoor unit. If you ever smell gas, leave the house first, call 911 or your gas utility from outside, then call us.
How it works
- Step 1
Tell us the symptom
Call or fill in the quote form. Describe the noise, the smell, the temperature, and when it started. That detail helps us bring the right parts and gives you an honest idea of the visit ahead.
- Step 2
We diagnose on site
A technician checks the thermostat, airflow, electrical connections, refrigerant behaviour and the outdoor unit. We tell you what failed and why, in plain language, before anyone reaches for a part or a price.
- Step 3
You choose the repair
We lay out the fix, any parts on order, and what happens if you wait. Once you agree, we do the work and confirm the system holds temperature before we pack up and leave.

Why homeowners call us
- Heat pumps are our normalIn this region heat pumps outnumber furnaces, so defrost boards, reversing valves and short cycling in wet weather are everyday work for us. We know how these systems behave in a cold December rain, not just on a test bench.
- Wet winter defrost problemsIce on the outdoor coil, a unit that runs and runs without warming the house, puddles that refreeze under the pad. We trace whether it is a sensor, a stuck valve, drainage, or airflow, then fix the actual cause.
- Filtration after smoke seasonWildfire smoke turned indoor air quality into a real conversation here. We look at filter fit, return sizing and IAQ options that your blower can actually push air through, rather than choking the system with the wrong media.
- We explain before we chargeYou get the diagnosis, the options and the trade-offs before work starts. If a repair is not worth it on an old system, we say so. No pressure, no jargon dumped on you at the door.
