Heating and Cooling for Keys and the Tenkiller Lake Community

Keys is a lakeside Cherokee County community where life runs at its own pace. Some homeowners live here year-round and depend on their heating and cooling systems every day. Others own waterfront cabins or weekend getaway properties that see heavy use in the summer and sit empty through the colder months. Both types of homes need HVAC service they can count on, and finding a company that will make it out to the lake without charging a premium or taking two weeks to schedule has not always been easy.

Girdner Heat and Air is based in Stilwell, just 20 minutes from Keys. We are a Cherokee County company, and the Tenkiller Lake corridor is part of our home turf. We service full-time residences, seasonal cabins, and everything in between. Our technicians understand the specific challenges that come with lakefront properties — humidity that pushes systems harder, condensation issues in homes that are opened and closed with the seasons, and outdoor equipment exposed to weather and wildlife year-round. We handle it all, and we do it at a fair price.

Complete Heating and Cooling Services in Keys, OK

We offer complete HVAC services to keep your Keys home comfortable and efficient throughout the year.

We repair and install central air systems, packaged units, and ductless mini-splits. Lakefront properties deal with higher humidity loads that make air conditioning systems work harder, and we make sure your equipment is up to the task. New installations include a load calculation for proper sizing.

Gas, electric, and propane furnace service. Many Keys homes run on propane, and we service every fuel type. We repair ignitors, thermocouples, pressure switches, and blower motors, and we install new systems matched to your home and fuel source.

Heat pumps are an efficient choice for the Keys area, providing year-round heating and cooling from one system. We install, repair, and maintain all types. We also service mobile home HVAC systems with the specialized equipment manufactured housing requires.

Whole-home air purifiers, UV germicidal lights, humidifiers, and dehumidifiers. Lakefront homes are especially susceptible to mold and mildew due to sustained high humidity, and properties that are closed up between visits can develop musty air quality that affects both comfort and health.

Prevent Issues With HVAC Maintenance

Regular maintenance is critical for homes in the Keys and Tenkiller area, where lake humidity, seasonal use patterns, and outdoor exposure put extra wear on HVAC equipment. Our maintenance services keep your system reliable no matter how you use your property.

System Performance Check and Cleaning — We inspect, clean, and test your full system to make sure it is ready for use. For seasonal lake homes, we recommend a system check before the first visit of the season to avoid unpleasant surprises.
Electrical Component Testing and Safety Inspections — We test capacitors, contactors, wiring, and safety controls. Lake-area humidity accelerates corrosion on electrical connections, making regular inspection critical for preventing unexpected shutdowns.
Airflow and Efficiency Optimization — We verify refrigerant charge, measure airflow, clean coils, check duct connections for leaks, and calibrate your thermostat for efficient operation.
Early Problem Detection — We catch corrosion on copper refrigerant lines, pest nesting in outdoor units, failing condenser contactors, and mold growth on evaporator coils before they lead to costly repairs or unhealthy indoor air.

Our maintenance plan includes two seasonal tune-ups per year, 15% off all repairs, priority scheduling during peak season, and an annual loyalty credit toward a future system replacement. Plans start at $17.91 per month.

What Keys Homeowners Say About Us

Whitney M. Warrior-Deerinwater

Had a great experience, especially the consultation! The information was as they presented, no hidden extras, it was a successful home project and the boys were so great to talk to and ask questions. All were knowledgeable and all worked efficiently. They also seemed to enjoy their work and how they happily carried one with each other. They needed to take more of the snacks but they were such a great representative of Girdners to have on our home projects! Highly recommended. Owner is also great to work with. Looking forward to working with the company again!!
