Expert Heating & Cooling Solutions for Seattle
Seattle homeowners rarely call an HVAC company when things are going well. They call when the AC dies in a heat wave, when the furnace clicks but never lights, when one bedroom stays freezing no matter what the thermostat says. Sammamish HVAC built its local reputation on those calls: picking up the phone, arriving with stocked trucks, and solving the real problem on the first visit. From quick capacitor swaps to full heat pump installations, our technicians handle every job with straight answers and honest numbers, and we treat your home like it belongs to a neighbor, because around here, it does.
Complete Heating & Cooling Services for Seattle Properties
Whether you own a single-family home, a rental property, or a commercial space in town, we have the know-how and equipment to handle the full range of heating and cooling work. Our technicians have spent years working on central air conditioners, gas and electric furnaces, heat pumps, and ductless mini-splits across the region, and we pay close attention to the climate patterns, housing stock, and local code requirements that shape how systems perform in this area.
On the residential side, we handle everything from quick fixes, like a failed capacitor, a pitted contactor, a dirty flame sensor, or a seized blower motor, to refrigerant leak repair, complete system replacements, and ductless additions. We size every new system with a proper load calculation instead of a rule of thumb, so you get even temperatures and reasonable utility bills instead of a unit that short-cycles itself to an early death. Our seasonal tune-ups clean coils, verify refrigerant charge, test safety controls, and check static pressure, the single best way to extend equipment life.
Commercial work makes up a large share of our work as well. We service rooftop units, split systems, and ventilation equipment for restaurant kitchens, retail stores, offices, and multi-unit properties, knowing that every hour of downtime costs your bottom line. To keep that downtime short, we keep common commercial parts stocked, diagnose fast, and schedule larger jobs around your operating hours whenever possible.
When Your System Fails in Seattle
Heating and cooling failures rarely wait for a convenient day, which is why we offer prompt, flexible scheduling for most situations. When you call, you'll speak with a real person who gets a technician headed to your door quickly. Our typical arrival window in the area is typically within a day for urgent calls, and a dead AC in a heat wave or a furnace out on a freezing night is the kind of call we move to the front of the line.
Common emergencies we handle include air conditioners blowing warm air, outdoor units that hum but won't start, furnaces that ignite and then shut down, breakers that trip whenever the system starts, frozen evaporator coils, clogged condensate drains backing up into the furnace cabinet, and thermostats that have stopped responding. Our trucks carry the capacitors, contactors, igniters, flame sensors, universal control boards, and fittings needed to finish most repairs in a single visit. Pricing is always upfront, so you know exactly what the work will cost before we begin.
Two common situations call for a quick step from you before a technician arrives. The first is an iced-over air conditioner: switch the system off at the thermostat and set the fan to "on" so the moving air thaws the coil, because continuing to run it can overflow the drain pan and damage the compressor. The second is a furnace that keeps cycling on and off or produces a burning smell. Shut it down at the switch and give us a call. Those few minutes can save you from a much larger repair.
Keeping Your Seattle HVAC System Running Longer
A little routine care makes all the difference between a system that lasts and one that breaks down in the middle of the season. Our advice for homeowners is a short list: fresh filters every one to three months, at least two feet of open space around the outdoor condenser, a gentle rinse each spring for the condenser coil, and a professional tune-up every spring and fall, so problems are found while they're still inexpensive.
Age matters too. Most central air conditioners run 12 to 15 years, furnaces 15 to 20, and heat pumps 10 to 15 with regular service. If your system is past that window and showing symptoms, such as climbing utility bills, rooms that never feel comfortable, or repairs stacking up season after season, a planned replacement is almost always cheaper and far less stressful than an emergency one in the middle of a cold snap.
Small problems rarely stay small for long. Consider a weak capacitor: swapping it out is a quick, affordable repair, but if it's ignored for a season, it can take the compressor with it, and just like that a minor fix has become a full system replacement. That's why we encourage homeowners to keep our number in their phone and call at the first hint of trouble. Catching it early saves money and prevents a few miserable nights.
Typical Heating & Cooling Issues in Seattle
The service calls we run around here follow familiar patterns. In summer it's air conditioners humming but not cooling, weak capacitors that finally quit on the first hot week, and iced-over evaporator coils. In winter it's furnaces that short-cycle, dirty flame sensors, and igniters that fail on the first cold night. Year-round we see thermostats misreading rooms, rising energy bills from dirty coils, and ductwork that leaks conditioned air into attics and crawlspaces. All of them start small, and all of them cost less to fix early. If your system is acting up, call (425) 969-4235 before the season turns it into an emergency.

Plenty of companies will sell you a new HVAC system. Sammamish HVAC earns trust around here by fixing the ones that don't need replacing and being straight about the ones that do. We find the actual fault before we quote a dollar, explain your options in plain terms with real numbers, and leave the decision to you. When replacement is the right call, we size the new system with a proper load calculation based on your home's real heating and cooling load, square footage, insulation, windows, and duct capacity, instead of defaulting to whatever's in the warehouse.
The workmanship holds up because we sweat the details: correct refrigerant charge weighed in rather than guessed, sealed duct connections, proper condensate drainage, verified combustion and airflow on heating equipment, and clean electrical work that passes inspection without drama. We show up when we said we would, cover your floors, haul away the old equipment, and test the full system in every mode before we leave. That's why so much of our local work comes from repeat customers and referrals, and why we back every job with a satisfaction guarantee.
