Our Services

Heating and air conditioning services for Oklahoma City

Oklahoma City systems have to handle demanding summer heat, abrupt cold fronts, wind, dust, and hard seasonal swings. These are the services that keep homes and businesses ahead of it.

Technician diagnosing an air conditioner at an Oklahoma City home

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.

Technicians installing a residential air conditioning system

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.

Seasonal air conditioner maintenance at an Oklahoma City home

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.

HVAC technician inspecting a residential furnace in Oklahoma City

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.

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.

HVAC Maintenance

ENERGY STAR recommends annual pre-season check-ups — cooling in spring, heating in fall. Two visits a year, timed so problems surface before the weather makes them urgent.

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.

Local Climate

HVAC built around Oklahoma City weather

Central Oklahoma runs roughly 73 days a year above 90°F and about 72 nights at or below freezing, and the changes tend to arrive fast. A simple seasonal rhythm keeps a system ahead of it.

  1. Early spring

    Cooling inspection and a check for storm debris in the outdoor unit before the first heat.

  2. Late spring

    Filters, airflow, and thermostat set for the season ahead, while it is still comfortable to work.

  3. Summer

    Watch cooling performance and keep the outdoor unit clear — OKC runs 73 days a year above 90°F.

  4. Fall

    Heating inspection before the first cold front, which tends to arrive without much warning.

  5. Winter

    Furnace or heat-pump readiness and safe operation through freeze-and-thaw swings.

Honest Guidance

Repair the system or consider replacement?

Repair may make sense when…

  • The system is relatively young.
  • The problem is isolated to one part.
  • The repair history is limited.
  • Comfort and efficiency are still acceptable.

Let's look at it together

The right call depends on the system in front of us — its condition, its age, and your home. We will tell you what we find and lay out the options, and the decision stays yours.

Request a System Evaluation

Replacement may be worth discussing when…

  • Breakdowns are becoming frequent.
  • Energy use keeps climbing.
  • Major components are failing.
  • Comfort stays uneven no matter what.
  • The system is near the end of its typical service life.
  • Repair cost is high relative to replacement value.

General guidance only. A recommendation depends on the system's condition, age, and your home — which we confirm on site.

Neighborhoods

HVAC service across Oklahoma City neighborhoods

From the older brick homes around Lake Overholser and the Meridian corridor — where the original ductwork is often still up in a vented attic — to the newer builds pushing out toward Deer Creek and Yukon, west and northwest Oklahoma City covers a lot of housing eras. We have worked most of them, and the age of a home usually tells us more about its comfort problems than the brand on the equipment does.

FAQs

Questions Oklahoma City homeowners ask

Straight answers — including the ones most HVAC sites dodge.

We handle heating and air conditioning service and installation — AC repair, furnace repair, maintenance, and replacement systems for both older and newer equipment. Serrato Heat and Air has been doing this for more than ten years in Oklahoma City, and HVAC is all we do. You can see the full list on our services page.

Yes. Serrato Heat and Air is a locally owned company serving residential and commercial customers across Oklahoma City. That covers houses, rental properties, offices, shops, and other small commercial spaces. Commercial equipment is often larger and sits on a roof, but the approach is the same: find out what the system is actually doing, then explain your options.

Home AC systems here run hard through long, humid summers, so we see a lot of the same things: dirty coils and filters choking airflow, worn capacitors, failed contactors, low refrigerant from a leak, clogged condensate drains, and outdoor units packed with cottonwood and grass clippings. Heat and storm debris are tough on equipment.

First, this is about home central air, not a car. Check that the thermostat is set to cool, the filter is not clogged, and the outdoor unit is clear of grass and debris and actually spinning. If those look fine, the cause is usually inside the sealed system or the electrical side — leave that to a technician. Call (327) 210-5999 and describe what you are hearing and feeling.

Common causes include a thermostat set to "on" instead of "auto" — which runs the blower between heating cycles — a dirty filter restricting airflow, a flame sensor or igniter problem, or a safety switch shutting down the burners. Check the thermostat setting and the filter. Do not open gas components or try to relight anything yourself.

Yes, furnace repair is core work for us. Before you call, check that the thermostat is on heat and calling for it, the furnace switch is on, and the breaker has not tripped. If you smell gas, leave the building, then call 911 or your gas utility from outside before calling anyone else. Otherwise, reach us at (327) 210-5999.

It depends on the system, not a rule of thumb. Repair often makes sense when the unit is relatively young, the fault is isolated, and it has a limited repair history. Replacement is worth discussing when breakdowns repeat, energy use keeps climbing, major components are failing, or comfort stays uneven. We will tell you what we find and let you decide.

Yes. We install replacement air conditioners, furnaces, and heat pumps for homes and commercial properties. Sizing matters more than most people expect — a unit that is too large short-cycles and handles humidity poorly, which shows up fast in an Oklahoma summer. We look at the property, not just the old unit label.

A common approach is twice a year — cooling checked in spring, heating checked in fall — so problems surface before the weather makes them urgent. If you have one system doing both, such as a heat pump, two visits a year still fits. Between visits, change filters on schedule and keep the outdoor unit clear.

Uneven temperatures usually trace back to airflow rather than the equipment itself: closed or blocked registers, leaky or undersized ductwork, poor attic insulation, or a system that no longer matches the home after a remodel. Upstairs rooms in Oklahoma City run hot in summer for exactly these reasons. Zoning or duct work can help.

We are based in west Oklahoma City and serve the OKC metro. Coverage depends on the address and what is on the schedule, so the honest answer is to ask rather than assume. Browse our service areas for the communities we list, and contact us to confirm availability at your address. If we are not the right fit, we will say so.

Call (327) 210-5999 or send the form on our contact page. Either way, the details that help most are: what type of property, what the system is doing (or not doing), roughly how old it is, and the best way to reach you. The more specific you are, the better we can prepare before we arrive.

Serrato Heat and Air is based at 1509 Oakhill Ln, Oklahoma City, OK 73127, on the west side of the metro. We are a locally owned shop, not a national chain branch. You can get directions from our contact page, or call (327) 210-5999 if you would rather just talk through what your system is doing.

Breakdowns don't wait for business hours, and we know it. What we won't do is post a 24/7 promise we haven't confirmed, because a call nobody answers at 1am helps no one. Tell us what your system is doing and we'll tell you straight what we can do and when. Availability can vary. Call (327) 210-5999 to ask about the fastest available appointment.
