Is It Time to Replace Your Mountlake Terrace HVAC System?

Most heating and cooling systems give plenty of warning before they quit for good. If two or more of these sound familiar, a replacement quote is worth a look.

15+ years old

Plenty of Mountlake Terrace homes still run equipment from the early 2000s. Past 15 years, efficiency drops and parts wear out faster.

Repairs keep adding up

Two or three repair calls in a year is a pattern, not bad luck. At some point, those bills are better spent on a new system.

Higher energy bills

A tired furnace or AC runs longer to do the same job, and your utility bill shows it. Newer equipment does more with less.

Rooms that never feel right

Cold bedrooms, a system that runs nonstop or one that can’t keep up can mean it’s worn out or was never sized right.

Cracked heat exchanger

A cracked heat exchanger can leak carbon monoxide. It’s a safety issue, and replacing the furnace is usually the safe fix.

No air conditioning

Summer heat waves are tough without AC. Central air or a heat pump keeps every room comfortable when it counts.

Not sure you need a new system?

Repair is always our first move. If a fix will keep your system running safely for years, we’ll tell you that before we ever quote a replacement.

Which System Is Right for Your Mountlake Terrace Home?

Gas furnace and central AC: the go-to setup for Mountlake Terrace homes with natural gas. You get strong, fast heat on cold mornings and central cooling for summer.

Heat pump: all-electric heating and cooling in one system. A Mitsubishi Hyper-Heat keeps full heating output down to 5°F, and it’s a simple way to add cooling to a home that never had it.

No ductwork? A ductless mini-split heats and cools room by room. It’s often the easiest way to cool a rambler whose ducts weren’t built for AC.

    Frequently Asked Questions

    Most furnace replacements we install run about $5,000 to $10,000. A furnace with central AC runs about $11,000 to $17,000, and a Mitsubishi Hyper-Heat heat pump system starts around $16,000. Prices are before sales tax. Use the calculator above for a price based on your home, and we’ll firm it up with a free in-home quote.

    Usually not. Most furnace and AC swaps are done in a single day, so the heat is back on that evening. Bigger jobs like a new heat pump, ductwork or an electrical circuit can add a day, and we’ll tell you before we start.

    Many Mountlake Terrace homes are mid-century ramblers, and older ductwork often needs a check before adding central AC. We do a load calculation at your home instead of matching the old unit, so the new system heats and cools evenly without short cycling.

    If your system is over 15 years old, needs frequent repairs, has a cracked heat exchanger or can’t keep the house comfortable, replacing usually makes more sense. If a repair is the smarter move, we’ll tell you that too.
