Residential · Mohave & Yavapai County
Your house is not a brochure. We size the system for the house you actually have.
Repair, replacement, and maintenance for homes, manufactured homes, and casitas across two counties, with the number quoted before anyone opens a panel.

Most of what goes wrong in a desert house is predictable.
Dust that packs a condenser coil. A capacitor that gives up at 112°. Ductwork in a 140° attic leaking a third of the air you paid to cool. A system somebody sized by matching the sticker on the old one instead of running the numbers. We see the same handful of failures over and over, and most of them are cheaper to prevent than to fix.
Air-Exx works on houses, manufactured homes, casitas, additions, and converted garages , and manufactured homes matter here, because plenty of contractors would rather not deal with the duct, clearance, and roof-curb realities that come with them. We do.
You get the service call price on the phone. The diagnostic is credited toward the repair when you approve it. You get the repair price before we start.
Plenty of our work is a small repair on a system somebody else told the customer to replace. We would rather have you for fifteen years than for one oversized invoice.
How we quote residential workWhen replacement really is the better money, we say so and show you why: the age, the repair history, and what the next three years realistically look like. Then we quote three tiers side by side so the tradeoff between price and performance is visible before you choose.
What we handle
AC Repair
Not cooling, short cycling, tripping the breaker, or water on the floor. We diagnose it and show you the reading before we touch anything.
Capacitors and contactors, condenser fan motors, compressors, refrigerant leaks found with a real leak search rather than a top-off, blower motors, control boards, and thermostats. We measure superheat, subcooling, and static pressure and show you the numbers.
AC & Heat Pump Replacement
Sized on a Manual J load calculation for your house, not by matching the tonnage of whatever is out there now.
Right-sizing matters twice: an oversized system costs more up front and then short-cycles every month after, which means worse humidity control and a shorter life. We quote three Trane tiers side by side, with the efficiency and staging differences spelled out.
Heating & Furnace Service
Furnaces, heat pumps, and auxiliary heat, including the altitude derate that gas equipment needs above about 4,000 feet.
Heating repair → Furnace & heat pump replacement →
Igniters, flame sensors, heat exchangers, gas valves, reversing valves, and defrost boards. Higher-elevation homes get the manufacturer's derate checked, because it is skipped often enough that we look for it every time.
Mini-Splits & Ductless
The right answer for a converted garage, a guest house, a casita, or a room the original ductwork never reached.
Single-zone through multi-zone, with line-set routing planned so it does not look like an afterthought on the side of your house. Heats and cools, no duct run required.
Ductwork & Airflow
In a hot attic or under a manufactured home, sealing the ducts is often cheaper than a new system and fixes the whole complaint.
We test static pressure to find restriction, inspect accessible runs for disconnects and crush points, and seal at the joints where most leakage happens. It is unglamorous and it is frequently the best money you will spend.
Preventative Maintenance
The visit that keeps you off the emergency list in August. Coil cleaning, refrigerant check, electrical, drain line, and a written condition report.
Cooling before summer, heating before the first hard freeze. Desert dust and hard water are the two things that shorten equipment life here, and both are maintenance problems rather than repair problems.
Upfront pricing, before we start
You get the service call price on the phone, before anyone heads your way. Once we have found the problem, you get the repair price before any work starts, and the diagnostic is credited toward the repair when you approve it. Commercial calls are quoted the same way. We install Trane, quoted in three tiers side by side.
Questions we get asked
What does a service call cost?
My AC runs but the house will not cool. What is wrong?
How long should a system last in this climate?
Do you work on manufactured homes?
Should I repair or replace?
Do you service evaporative (swamp) coolers?
Where we work
No cooling? Call before the house heats up.
