HVAC Company in Des Moines, WA
Dalton Heating & Air handles AC repair, heat pump installation, and furnace repair for homeowners throughout Des Moines, WA. The marine air here does more than cool the summers, it pushes salt moisture into outdoor condenser coils and ages them faster than inland equipment. Most homes in Des Moines sit on bluffs or in protected valleys near Puget Sound, which means venting, drainage, and airflow each behave a little differently from one street to the next. Call (361) 306-9515 and you will get a written price before any work starts, a live person on the phone, and a full-year written guarantee on every repair.
Why Des Moines Homes Are Different
Des Moines sits right on Puget Sound, and that location shapes the HVAC work here more than anything else. Salt air shortens the life of outdoor units. Condenser coils corrode faster near the waterfront, especially in the Zenith and Woodmont neighborhoods where homes face the open water. We regularly find pitted coil fins and rusted electrical contacts on systems that would still look clean ten miles inland.
The housing stock is another factor. Des Moines has a mix of 1950s and 1960s ramblers near the water, 1970s split-levels through the mid-city hills, and newer construction up toward the Normandy Park border. Older homes often run original ductwork sized for heating only, which means AC retrofits and heat pump conversions need real attention to airflow, not just equipment swaps. Some neighborhoods also sit under tree cover, which sounds pleasant until you are clearing pine needles out of a condenser twice a season. A few of the bluff-side lots have steep driveways and narrow side yards, so we plan equipment access before we arrive. Nothing about this city is flat or uniform, and the work reflects that.
Our Main Des Moines Services
AC repair and furnace repair are the calls we take most often from Des Moines homeowners, with heat pump installation close behind as more people replace aging gas furnaces with electric systems. Here is how each one works around here.
AC Repair in Des Moines
When the summer sun hits a west-facing wall in Des Moines, a struggling AC shows itself fast. Salt corrosion on contactors and capacitors is the most common failure we see near the water, followed by low refrigerant and clogged condensate lines. We diagnose the exact problem, hand you a written price, and complete the repair in one visit whenever the part is on the truck. If your system is short-cycling or blowing warm air, start with our AC Repair in Des Moines page for the full breakdown of what repairs cost and when a recharge is the right call.

Heat Pump Installation in Des Moines
A heat pump makes a lot of sense in Des Moines. Winters are mild enough that a cold-climate heat pump handles nearly all the heating load, and summers are getting warmer every year. The catch is that many homes here still run original ductwork from the mid-century build, so a proper install starts with a load calculation and a duct inspection, not a box in the driveway. We quote the job in writing, set an install date, and handle the rebate paperwork for you. See Heat Pump Installation in Des Moines for equipment options and installed pricing.

Furnace Repair in Des Moines
Most furnace breakdowns in Des Moines happen on the first cold snap of November, when a system that sat idle since April finally gets asked to work. Ignitors, flame sensors, and pressure switches are the usual culprits, and we keep the common parts stocked so a weekday call is often a same-visit fix. If your furnace is blowing cold air or cycling off early, the Furnace Repair in Des Moines page covers typical repair costs and what the written guarantee covers.

Pricing for HVAC Company in Des Moines, WA
| Service | Typical range in Des Moines |
|---|---|
| AC repair | $150 – $650 |
| Furnace repair | $150 – $700 |
| AC installation | $3,500 – $7,500 |
| Tune-up | $80 – $200 |
What pushes a repair toward the top of those ranges is usually the part itself. A failed compressor or blower motor costs more than a capacitor or pressure switch. Homes near the waterfront also tend to need more electrical work due to salt corrosion on wiring and terminals. Whatever the number, you see it in writing before we start, and every repair is guaranteed for a full year.

Yes, and it is measurable. Outdoor coils and electrical connections near the water corrode faster than inland systems. Regular maintenance and coil cleaning help, and we recommend a tune-up at least once a year for any Des Moines home within half a mile of the shoreline.
