AfterFast, Reliable AC Installation Across Des Moines
AC installation in Des Moines runs $3,500 to $7,500 for most homes, and the job usually takes one to two days once equipment arrives. We serve the Highline plateau, the bluff streets above the marina, Woodmont, Zenith, and every neighborhood between. Call (747) 966-3037 for a written quote before any work starts. Luis Serrano leads our installation crews, and every job includes the Cedarwell Care Promise: a set price, shoe covers and drop cloths inside your home, and a photo of the clean-up before we leave.
Older Des Moines homes present a specific challenge: many were built in the 1950s and 1960s with oil heat or electric baseboards, no ductwork to speak of, and panels that were sized for a different era. We plan installs around those realities, not around them. Whether you’re on Marine View Drive or up in the Highline neighborhoods, we’ll tell you what your house can actually support, what it will cost, and how long it will take.
Key Takeaways:
- Full AC Installation in Des Moines runs $3,500-$7,500, with a written quote before any work begins.
- Heat pump conversion is the defining job here: post-WWII homes with no ducts need real planning, not a like-for-like swap.
- Salt air near the marina corrodes outdoor coils faster than inland King County. We quote coil-guard coating and marine-grade fasteners on waterfront-adjacent installs.
- Shoe covers, drop cloths, and a clean-up photo are included on every job. Not an add-on.
Why Meadowsweet Heating & Air Is Des Moines’s Preferred AC Installation Company
Homeowners along Redondo Beach Drive, 216th Street, and the bluff-side streets around Des Moines Marina call us for the same reason: we show up when we say we will, and we leave the house the way we found it. Meadowsweet Heating & Air is part of the Cedarwell family of HVAC companies, founded in 2004. Luis Serrano runs our installation work personally. Every technician is background-checked, uniformed, and follows our C.A.R.E. values code: clean up like it’s their own home, ask before moving anything, respect the family’s time, and explain the price before the work starts.
We work across nine equipment brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. That matters in Des Moines because no single brand fits every house. A 1962 split-level off the bluff has different duct realities than a 1978 rambler up on the plateau. We quote the equipment that fits the house, not the equipment we happen to have in the truck.
Every job carries the 365-Day Done Right Promise. If it’s not done right, we make it right. No runarounds, no fine print. And a live person answers our phone 24 hours a day, seven days a week, including nights and weekends. No voicemail queue.
HVAC Installation in Des Moines
HVAC Installation in Des Moines typically means one of two things: replacing an aging furnace-and-AC setup, or retrofitting a house that never had central air at all. The second is far more common here. The bulk of Des Moines’s residential streets, from the Highline plateau down to the bluff above the Sound, were built in the 1950s through the 1970s with oil furnaces or electric baseboard heat. Those systems left no duct infrastructure for a modern forced-air system. Our AC Installation team sizes every job with a full load calculation, not a rule-of-thumb guess based on the square footage of the old system.
Full HVAC installation in Des Moines runs $3,500 to $7,500 for most homes. The number moves based on whether we’re working with existing ductwork, adding duct runs, or switching to ductless mini splits. We give you that number in writing before any work starts, and it doesn’t change unless the scope changes and you approve it first.
Ducted furnace-and-AC replacement
When a home already has forced air, we can often reuse the duct trunk and focus on sealing leaks, re-balancing runs, and correcting static pressure before the new equipment goes in. Older Des Moines ducts leak at the joints. Sealing them is usually cheaper than replacing them and makes the new system quiet in every room.
Ductless mini split installation
Homes with no ducts, or homes with additions that never got proper airflow, often do better with ductless mini splits. We install single-zone and multi-zone systems that let you cool one room or the whole house. The outdoor units are compact enough for tight bluff-side lots where a traditional condenser pad would eat half the yard.
Heat Pump Installation in Des Moines
Heat Pump Installation in Des Moines is the fastest-growing HVAC job in the city. Washington State’s electrification mandates are pushing homeowners off oil and electric-resistance heat, and this city has a lot of both. The marine climate is mild enough that a heat pump runs efficiently year-round. Add the 2021 heat dome, which pushed temperatures past 100°F across the region, and the shift toward cooling-capable heat pumps went from gradual to permanent.
A heat pump install here runs $3,500 to $7,500 for most homes. Ductless systems and ducted central heat pumps both live in that range. The difference comes down to the house: attic clearance, crawl space access, panel capacity, and how many rooms need conditioned air.
Central ducted heat pump retrofits
If your home already has working ductwork from a furnace, a ducted heat pump can replace the whole heating-and-cooling side in one job. We run a full load calculation and static pressure test before quoting. The original 1950s duct trunk in a Des Moines home was often undersized even for the oil furnace it shipped with. Dropping a modern heat pump onto it without correction means the blower motor overworks and the far rooms never catch up.
Cold-climate heat pumps for bluff-side homes
Homes near the marina deal with two realities at once: salt-laden air and winter damp that never quite freezes. A cold-climate heat pump rated for marine air conditions handles both. We coat the condenser coil and use marine-grade fasteners on any install within a few blocks of the water. It costs a little more up front and saves a replacement coil five years later.
Trusted Brands We Service in Des Moines
We install and service Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Des Moines homes near the water, we often recommend Bryant or Daikin heat pumps with factory coastal-protection options, or a York unit paired with our coil-guard coating and marine-grade fasteners. Rheem remains a strong value choice for plateau homes where salt air is not the dominant factor. We keep common parts stocked for all nine brands, which cuts days off repair and install timelines for Des Moines customers. When a compressor fails in the middle of a summer week, waiting on a regional parts depot is not a plan; it’s an inconvenience you didn’t sign up for.
Common AC Installation Problems We See in Des Moines Homes
- Undersized original ductwork choking modern equipment. The 1950s and 1960s homes that dominate Des Moines neighborhoods were built for oil heat and gravity airflow. A modern heat pump needs a tighter, more balanced duct system. When static pressure spikes, the blower motor works harder, runs louder, and dies early.
- Electrical panels that cannot carry the load. Many Highline-plateau and bluff-area homes still run 100-amp service or fused panels. A heat pump with a backup heat strip draws more than that panel can safely deliver. An install quoted without a panel review stalls at inspection, and the homeowner pays for a surprise service upgrade.
- Salt-air coil corrosion near the marina. The same onshore air that makes the Des Moines waterfront so pleasant pits condenser coil fins and corrodes electrical contacts years before their rated service life. This doesn’t show up in inland jobs in Kent or Burien. Without coil-guard coating and marine-grade fasteners, a waterfront-adjacent unit fails early and often.
- Single-zone systems fighting an unbalanced floor plan. Many split-level and rambler homes here were built with one thermostat for the whole house. The south-facing rooms bake while north-facing rooms stay cold. A proper load calculation and zoning solve what a bigger unit never will.

FAQs About AC Installation in Des Moines
Because the old equipment wasn’t sized for heat pump operation, and the ductwork that came with the house was built for oil heat. A 1960s oil furnace in a Des Moines home moved air differently than a modern heat pump needs to. The duct trunk was typically undersized, joints leak, and static pressure spikes when a heat pump’s blower pushes through. We run a load calculation and a static pressure test before quoting so the new system actually works in every room, not just the hallway by the thermostat. Call (747) 966-3037 for a full assessment.
Yes. The salt-laden onshore air off Puget Sound corrodes outdoor condenser coils and electrical contacts faster than the inland air in Kent or Burien. Bluff-side homes near Des Moines Marina routinely show pitted coil fins and rusted contactors years before their rated service life. We include coil-guard coating and marine-grade fasteners on any install within a few blocks of the water. It’s standard practice for us here, not an upsell.
Many won’t, not without a service upgrade. Homes in the Highline plateau area commonly run 100-amp service or fused panels. A modern heat pump with a backup heat strip needs 40 to 60 amps by itself. If your panel can’t carry that, the install stalls at inspection. We check panel capacity before we quote, and if an upgrade is needed, we tell you the exact cost up front. No surprises after the permit is pulled.
SEER2 is the new federal efficiency standard for heat pumps and air conditioners, and it’s a slightly tougher test than the old SEER rating. For Des Moines homeowners, the practical meaning is this: a SEER2-rated heat pump from 2024 or later uses less electricity than older equipment, which matters if you’re converting from oil or electric baseboard heat. Washington’s electrification mandates and utility rebates also reward higher SEER2 equipment. We’ll show you the rebate paperwork and the annual operating cost difference for every option we quote.
Because the condenser is only half the system, and in a Des Moines home built between 1950 and 1975, the ductwork is usually the weak half. A new heat pump on leaky, undersized ducts will run louder, use more power, and leave the far rooms uncomfortable. Duct sealing and a proper load calculation cost a few hundred dollars and make the difference between a system that works and one that disappoints. We’ll show you the static pressure readings before and after so you can see what your money bought.
