HVAC Installation, Repair & Maintenance in Birmingham, AL

Heating and air is the one system in the house you only notice when it stops. Precision Services has kept Birmingham-area homes and businesses comfortable for 35+ years — repair, replacement, installation, and maintenance on every kind of system we run into here. One licensed, insured, in-house crew out of McCalla. We service all major brands, we quote before we work, and the phone gets answered at 2 a.m.

Full-Service HVAC for Birmingham Homes & Businesses

We handle the whole system, start to finish: HVAC repair when something quits, HVAC installation when a unit is past saving, and the seasonal maintenance that keeps you from needing either. Residential and commercial, and we work on whatever is already in the building — heat pumps, gas furnaces, straight-cool air conditioners, dual-fuel systems, package units, and ductless mini-splits.

Because we’re a multi-trade shop, one call covers it. If the problem on your HVAC service call turns out to be electrical — a dead breaker, a bad disconnect, failed wiring at the condenser — we don’t hand you a second phone number. That’s the same crew. The same goes for the rest of the property: electrical work, plumbing, and septic service all run out of the same shop in McCalla.

What a service call looks like

Our service call fee is $79. That covers getting a licensed technician out to you and a real diagnosis — not a guess and not a sales pitch. You get the problem explained in plain English and an upfront price before any work starts, with no hidden costs. If a repair isn’t the right answer, we’ll say so and show you the replacement numbers instead. Financing is available through Wells Fargo.

Heat Pump Repair & Installation in Birmingham

Most homes around Birmingham run on a heat pump, and for good reason — our winters are mild enough that one handles them efficiently without the running cost of a furnace. It also means the heat pump is doing something nearly every day of the year, and when it fails it usually fails in the middle of a cold snap.

We repair every common heat pump failure: refrigerant leaks, failed reversing valves, bad capacitors and contactors, iced-up outdoor coils, defrost-cycle faults, blower and fan motor failures, and thermostats that never hand off to auxiliary heat. We diagnose first and tell you straight whether a repair makes sense or you’re better off replacing.

Heat pump not heating?

Before you call, check two things: whether the outdoor unit is actually running, and whether the thermostat is stuck on emergency heat. Running on auxiliary heat alone will double an Alabama power bill in a week. If the outdoor unit is iced over, don’t chip at it — that’s how coils get punctured. Shut it down and call us.

New heat pump installation

We size the system to the house — not to whatever came out of it. An oversized unit short-cycles, never pulls the humidity out of an Alabama summer, and wears itself out early. We walk you through efficiency ratings, single-stage versus two-stage, and what the operating cost actually looks like on a real power bill here. Financing available through Wells Fargo.

Heating Repair, Installation & Furnace Service

Whether you heat with a heat pump, a gas furnace, or a dual-fuel system, we repair and replace all of it. The calls we run most: no heat at all, short cycling, a blower that runs but never warms the house, pilot and ignition faults, cracked heat exchangers, and thermostat failures.

Anything involving a cracked heat exchanger or a suspected gas leak is a safety issue, not a comfort issue. Shut the system down, get everyone out if you smell gas, and call us immediately. We’re licensed for gas work and we don’t cut corners on it.

Replacing a furnace or heater

When a system is past saving, we give you the honest comparison for your house — heat pump, gas furnace, or dual-fuel — including what each actually costs to run in this climate, not a national average. Most Birmingham-area homes do well on a heat pump; some don’t. We’ll tell you which one you have.

Heating with gas? Cracked heat exchangers, ignition faults, short cycling and gas safety are covered in depth on our furnace repair and replacement page.

Air Conditioning Repair & Installation

An Alabama summer is no place to be without air conditioning. We repair, replace and install AC systems for homes and businesses across the Birmingham metro, from refrigerant leaks and failed capacitors to frozen coils and clogged condensate lines. For what to check first, the failures we fix most, and how to decide between repair and replacement, see our AC repair page.

Ductless Mini-Split Service & Installation

Mini-splits are the right answer for the rooms central air was never run to — additions, garages, workshops, sunrooms, and bonus rooms over the garage — and for older homes with no ductwork at all. We install, repair, and service ductless mini-split systems for both heating and cooling.

Common mini-split problems we fix: indoor head units that won’t respond to the remote, water dripping from the indoor unit, refrigerant line and line-set issues, and outdoor units that won’t start. We also service mini-splits somebody else installed — you don’t have to track down the original company.

Thermostat Installation & Smart Thermostats

A bad thermostat imitates a broken system, and a smart thermostat wired wrong to a heat pump will quietly run your auxiliary heat all winter while you wonder why the power bill doubled. We install and correctly configure programmable and smart thermostats, including the heat-pump-specific wiring most DIY installs get wrong.

HVAC Maintenance & Seasonal Tune-Ups

Most of the emergency calls we run were preventable. A seasonal tune-up covers coil cleaning, a refrigerant check, electrical connections and contactors, the condensate drain, filters, and a full safety inspection — keeping the system efficient, holding most manufacturer warranties valid, and catching the small failures before they become the 2 a.m. call.

Best timing in Alabama: a cooling tune-up in spring, a heating tune-up in fall. Ask us about scheduling both so you’re not thinking about it.

24/7 Emergency HVAC Service

No heat on the coldest night of the year, or no AC in an August heat wave, is a genuine emergency — especially with young kids, elderly family, or pets in the house. Our line answers 24/7, and because our crews are in-house, one call gets you the diagnosis and the fix. Call (205) 807-6319.

Heating your water rather than your house? That’s a plumbing job — see our water heater services.

Serving Birmingham, McCalla, Bessemer & Hueytown

Our shop is in McCalla, which puts our trucks minutes from Bessemer, Hueytown, Bucksville and the Tannehill area, and straight up the I-459 / I-20/59 corridor into Birmingham. Closer trucks mean faster response on the days when everybody’s system fails at once — the first hard freeze, the first 95-degree afternoon — and those are exactly the days it matters.
