Everything We Do
HVAC Services in Oklahoma City, OK
Heating and cooling is the only thing we do, and we do it for homes and businesses across the Oklahoma City metro. Here is the full range, grouped by the part of your system it touches.
Air Conditioning
Air Conditioning Services in Oklahoma City, OK
Oklahoma City averages more than 73 days a year above 90°F, and around a dozen above 100°F. A cooling system here does not get an easy season. Serrato Heat and Air repairs, replaces, and maintains residential and commercial air conditioning across the metro.
AC Repair
Warm air at the vents, a system that runs without cooling, short cycling, ice on the line, or a breaker that keeps tripping. We find out which fault you actually have before touching a part, then explain what it takes to fix it.

AC Installation
A new system for a new build, an addition, or a first-time install. Sizing is the whole job: Oklahoma County design conditions run to 100°F, and a unit picked off the old label rather than the house tends to short-cycle and leave humidity behind.

AC Replacement
When repairs keep stacking up, ENERGY STAR suggests looking hard at any AC past ten years. We walk the actual system, tell you what we find, and lay out the options. The decision stays yours.

AC Maintenance
ENERGY STAR recommends a cooling check-up every spring, before the season makes a small fault into an emergency. Coils, airflow, drainage, controls, and the electrical side — checked while it is still comfortable enough to work outside.

Ductless Mini-Splits
For the addition the ductwork never reached, the garage shop, the sunroom that has never been comfortable. A mini-split conditions one space well without extending a duct system that may already be struggling.

Commercial Air Conditioning
Rooftop units and light commercial cooling for offices, shops, and restaurants. When cooling fails in a business, the cost is not just comfort — it is the trading day. We work around how your space actually runs.

Heating Repair, Installation, and Service in Oklahoma City
Oklahoma City winters are not long, but they are sharp. Roughly 72 nights a year drop to freezing and about 15 fall to 20°F or below, usually arriving as a front rather than a season. Serrato Heat and Air keeps furnaces and heat pumps working through it.
Furnace Repair
A furnace that will not start, blows cool air, cycles oddly, or smells wrong. Furnace repair is core work here. If you smell gas, leave the building and call 911 or your gas utility from outside first — then call us.

Furnace Installation
A new furnace, sized and vented for your house. Oklahoma County heating design conditions sit near 13°F — cold enough to matter, mild enough that oversizing is a real and common mistake.

Furnace Replacement
ENERGY STAR suggests taking a hard look at any furnace past fifteen years. We check what you have, tell you what we find, and give you the options — without using fear as a close.

Heating Maintenance
ENERGY STAR recommends a heating check-up each fall. In Oklahoma the first real cold front tends to arrive without much warning, and it is the moment every untested furnace gets tested at once.

Heat Pumps
Oklahoma City sits in genuinely good heat pump territory — January averages around 39°F. We service, repair, and install them, and we will explain what normal looks like, including the steam that alarms people every winter.

Commercial Heating
Heating for offices, shops, and light commercial spaces. Oklahoma cold arrives as a front, so the failure is rarely gradual — it is Monday morning and the space is 48°F with customers due at ten.

Indoor Air Quality Services in Oklahoma City, OK
Oklahoma sends a lot through a house: windblown red dust, cedar and ragweed pollen, storm debris, and humidity that swings from 80% in the morning to 55% in the afternoon. Your HVAC system is the only thing filtering most of it.
Air Purifiers
The EPA recommends at least MERV 13 for particle filtration. But a denser filter raises static pressure, and a system that was marginal on airflow will not thank you for it. The filter has to fit the system, not just the goal.

Humidity Control
Oklahoma City humidity averages around 80% in the morning and 55% by afternoon. Summers feel heavy; winters dry out. Often the fix is not a new box — it is an oversized AC that cools too fast to dehumidify.

UV Air Purifiers
UV air treatment gets sold with claims we will not repeat. Here is the honest version of what it is for, what it is not, and whether it makes sense on your system.

Ductwork Services for Oklahoma City Homes and Businesses
ENERGY STAR estimates that about 20 to 30 percent of the air moving through a typical duct system is lost to leaks, holes, and poor connections. In an Oklahoma City attic in July, that is conditioned air you paid for, heating your attic.
Duct Repair
One room that never gets comfortable, or vents that barely move air. Often the equipment is fine and a duct run came apart in the attic — cheaper to find than to guess at.

Duct Sealing
ENERGY STAR estimates about 20 to 30 percent of the air moving through a typical duct system is lost to leaks and poor connections. Sealing the accessible runs is some of the least glamorous, best-value work in this trade.
