Central AC Installation in Spokane, WA
Central AC installation means putting in a split system — an outdoor condenser, an indoor coil that mounts to your furnace, and connecting everything through your existing duct system. It's the most common way to add whole-home cooling to a Spokane house that already has forced-air heat. The ducts do the distribution work; we provide the cooling equipment.

When to Call
When You Need Central AC Installation
- Your home has a gas furnace with ductwork but no cooling equipment was ever installed
- You replaced window units every summer and want a permanent, cleaner solution
- Your existing ductwork was already sized for AC but the equipment was never added
- You're selling the home and buyers expect central cooling in the Spokane market
- Your allergies are aggravated by the dust that portable and window units push around
- You want one thermostat controlling temperature throughout the entire house
How It Works
Our Process for Central AC Installation
- 1
Duct assessment
We inspect your existing duct system first. Ducts that worked fine for heating sometimes need minor adjustments to handle airflow for cooling. We check before we commit.
- 2
Equipment sizing
We do a proper load calculation — square footage, ceiling height, window area, insulation quality. Guessing on size causes problems for years afterward.
- 3
Coil and condenser selection
The indoor coil has to match your furnace brand and the outdoor condenser. Mismatched equipment underperforms. We spec a matched system, not just whatever's available.
- 4
Installation
We mount the outdoor condenser, install the evaporator coil inside the furnace cabinet, run refrigerant lines, and connect to your electrical panel. Typically a one-day job.
- 5
Refrigerant charge and startup
We charge the system, verify pressures at both high and low side, check airflow at the registers, and confirm supply and return temperatures are in range.
- 6
Thermostat check
We confirm your existing thermostat supports cooling mode or install a compatible one. We program it and make sure you know how to use it.
What's included
- Manual J load calculation to properly size the equipment for your home
- Matched evaporator coil installation inside the existing furnace air handler
- Outdoor condenser installation on a new pad or existing concrete surface
- Refrigerant line set installation between indoor and outdoor equipment
- Electrical disconnect and wiring from panel to outdoor unit
- System startup, refrigerant charge verification, and airflow testing at registers
What's not included
- Duct repairs or modifications if the existing system has leaks or undersized runs
- Concrete pad installation if the outdoor unit location requires new ground prep
- Furnace replacement if the existing air handler is incompatible with modern AC equipment
Real Situations
Common Scenarios in Spokane
A homeowner in the Spokane Valley has a 1990s home with a functioning gas furnace but the AC condenser was removed years ago by a previous owner.
We check if the original coil is still in the furnace cabinet and whether it's compatible with current equipment. If it is, we just need a new outdoor unit and refrigerant lines. If the coil is gone or degraded, we quote a matched coil and condenser together.
A homeowner near Liberty Lake wants central AC installed before July and mentions their furnace is only three years old.
A newer furnace is usually straightforward to match. We identify the furnace model, spec a matching coil and condenser, pull the permit, and schedule installation. Newer furnace cabinets almost always have the coil slot already built in.
A homeowner in Spokane's Perry District has a 1960s home with original ductwork and wants central AC for the first time.
Older duct systems sometimes have leaks or undersized return air runs that cause problems with cooling. We assess the duct condition before recommending equipment. If the ducts need work first, we tell you and quote it separately so you can make an informed decision.
Spokane Context
Why this matters in Spokane
Spokane saw a lot of housing construction in the 1970s through 1990s where builders ran ductwork for heating but left the AC installation as an afterthought. That means a significant number of Valley and South Hill homes have all the ductwork already in place but no cooling equipment. Central AC installation in those homes is often simpler and faster than people expect.
Straight Talk
About pricing & scope
The main variables that change the cost of this job are duct condition, how far the line set needs to run, and whether the electrical panel has a circuit available for the condenser. We can't always know all of this until we're on-site. If we find something during installation that changes the scope, we stop and talk to you — we don't just add it to the bill at the end.
