All Seasons Heat and Air in Oklahoma City: Licensed Contractor With Load Calculations and Maintenance Plans

All Seasons Heat and Air is a licensed HVAC contractor serving Oklahoma City residential and light commercial properties, operating since the mid-1990s with a focus on air conditioning and heating system installation, replacement, and maintenance.

What All Seasons Heat and Air actually does

The company handles full-system replacements, new installations, repairs, and preventive maintenance for homes and small commercial spaces across the Oklahoma City metro. They are Oklahoma Construction Industries Board licensed, a requirement for any contractor installing or replacing HVAC systems in the state. The business operates from a single location and dispatches technicians to job sites rather than maintaining a showroom.

Services and pricing

All Seasons offers three main service tiers:

System replacement and installation. New unit pricing depends on the SEER rating (Seasonal Energy Efficiency Ratio) and tonnage required for the property. A standard 3-ton unit with a SEER rating of 14 to 16 typically runs $4,500 to $6,500 installed, though pricing varies based on ductwork condition and whether the job requires a permit (Oklahoma City requires permits for new installations and most replacements). The contractor performs a load calculation on the home before quoting, a step that determines the correct system size; undersized or oversized units waste energy and money. Ask whether a load calculation is included in the estimate.

Repairs. Service calls start at a diagnostic fee of approximately $75 to $100, applied toward the repair cost if you proceed. Common repairs like refrigerant recharge, capacitor replacement, or thermostat fixes range from $200 to $600. Emergency or after-hours service (nights and weekends) carries an additional charge; confirm current rates when calling.

Maintenance contracts. Annual plans typically cost $150 to $250 per year for two seasonal tune-ups (spring for air conditioning, fall for heating), filter changes, and priority scheduling. Some contracts bundle a discount on repairs.

Prices change periodically. Contact All Seasons directly to confirm current rates and any seasonal promotions.

How it compares to other Oklahoma City HVAC providers

All Seasons competes primarily with larger regional chains like Comfort Systems USA and Turner Heating & Cooling, as well as smaller independent contractors. Comfort Systems USA operates multiple service centers across Oklahoma City and offers 24/7 emergency service, making it the choice for customers who prioritize immediate after-hours availability; however, it is part of a national chain, which can mean less continuity with individual technicians. Turner Heating & Cooling similarly emphasizes rapid response and has been in the market longer (since 1973) with more brand recognition. All Seasons sits between: smaller than the major chains, with less brand visibility but often closer relationships with homeowners who value working with an independent, locally rooted contractor. Choose All Seasons if you prefer a smaller operation and are willing to book service within standard business hours; choose Comfort Systems or Turner if you need a large operation with extended emergency availability and faster same-day dispatch options.

Who it suits and who it does not suit

All Seasons works well for homeowners in Oklahoma City who need a system replacement, are interested in detailed load calculations, and prefer to work with a licensed contractor they can speak with directly. It is a fit if you plan to stay in your home long enough to benefit from a maintenance contract, which reduces the risk of unexpected failures during Oklahoma's hot, humid summers and occasionally cold winters.

It does not suit customers who require 24/7 emergency HVAC service or expect same-day dispatch during peak seasons; those should contact a larger regional operation. It is also not the right choice if you need only minor repairs at the lowest possible price point, as smaller jobs may not be cost-effective given diagnostic and trip fees.

What the first visit involves

Call for a quote. The contractor will schedule a technician to inspect the system, assess ductwork, and take measurements. For replacements, the technician performs a load calculation to size the unit correctly. The estimate will itemize equipment, labor, permit fees (if required), and any ductwork modifications. If you approve, scheduling typically happens within one to two weeks unless it is peak summer cooling season, when the wait may extend longer.

Hours, parking, and logistics

All Seasons operates during standard business hours. Confirm current hours when you call, as they vary seasonally. The company is dispatch-based; technicians arrive at your home for estimates and service calls. Parking is not a factor.

All Seasons Heat and Air has maintained steady operation in Oklahoma City by handling the core HVAC work reliably and without the overhead of a large chain, making it a solid option for homeowners who prioritize accuracy in system sizing and continuity with their contractor.
