Services
What we do
- 01
System replacement
A full AC or furnace replacement, sized to your house and ductwork rather than to the biggest unit on the truck.
- 02
AC repair
Refrigerant checks, compressor and capacitor diagnosis, and airflow troubleshooting for units that are short-cycling or blowing warm.
- 03
Heating repair
Furnace and heat pump troubleshooting — pilot lights, cracked wires, control boards, and airflow issues that keep rooms uneven.
- 04
Preventive maintenance plans
Seasonal checks on refrigerant charge, electrical connections, and airflow so small issues get caught before a system fails outright.
- 05
Ductwork & airflow
Sealing, resizing, and repairing duct runs so conditioned air actually reaches the rooms it's supposed to, instead of leaking into the attic.
- 06
Mini-split systems
Ductless heating and cooling for additions, converted garages, and home offices that were never on the main system.

Gauges before guesses
We check refrigerant pressure and airflow with instruments before naming a cause.
Sized to the house
Replacement equipment is sized to your ductwork and load, not to the largest unit available.
One crew, start to finish
The technicians who quote the job are the ones who install it.
We test the system before we talk about replacing it
SDAC works out of Lakeside, in the inland heat where an AC that quits in August is not a minor problem. A visit starts with gauges and airflow checks, not a sales pitch — we want to know what the system is actually doing before anyone says the word 'replace.' Some houses out here were never ducted right to begin with, and stucco walls hide a lot. We go through the attic, the plenum, the sheet metal runs, and tell you plainly what we found. If the fix is small, we say so.
Should I repair my AC or replace it?
That depends on what's actually failing and what the system's condition is otherwise. We check the compressor, coil, and refrigerant charge first and tell you honestly whether a repair holds up or whether you'd be pouring money into an aging unit.
How soon can someone come look at my system?
Call and we'll go over what's happening and get you on the schedule — no-cool and no-heat calls get worked in ahead of routine maintenance, so tell us what's going on when you call.
My addition doesn't have ducts. What are my options?
A mini-split is usually the fix for a room that was never tied into the main system. It runs on its own line set, heats and cools that space independently, and doesn't require opening up the existing ductwork.
How a job runs, start to finish
Say what's going on
A call or a text — photos help if they're easy to take.
Agree on the work first
Scope and price settled before anything starts. If something changes mid-job, it gets agreed the same way.
The work gets done
On the day you set, in the way you agreed.
Walk it before it's done
Point at anything that isn't right while the tools are still out — that's what the walkthrough is for.
Before you hire anyone
Four flags worth knowing — whoever you call
Ask these of anyone bidding your job — us included. A good answer costs nothing; a bad one saves you the whole mistake.
A price before anyone's seen the job
Real quotes come after eyes on the work. A number over the phone is a number that changes.
Nothing in writing
Scope, price, and who buys materials — settled before work starts, on paper or in a text thread.
Pressure to start today
Good operators are booked. Same-hour availability with a discount attached is its own answer.
No paper trail on payment
However you pay, there should be a record of what was agreed and what was done.
