Regular maintenance might not sound exciting, but it’s the difference between a comfortable home and costly repairs. Most homeowners in Stilwell, OK don’t think about their heating and cooling system until something goes wrong. But here’s the thing: seasonal HVAC maintenance checkups can save you hundreds of dollars and keep your home comfortable no matter what Mother Nature throws at you.
Your HVAC system works hard every single day, dealing with Oklahoma’s scorching summers and chilly winters. Without proper care, that equipment starts breaking down faster, driving up energy costs and leaving you stuck without heating or cool air when you need it most. That’s where a solid seasonal maintenance checklist comes in.
At Girdner Heat and Air LLC, we’ve seen countless furnace failures and AC breakdowns that could have been prevented with simple seasonal upkeep. This guide walks you through exactly what your system needs during each season to keep running smoothly.
Why Seasonal HVAC Maintenance Actually Matters
Think of your HVAC system like your car. You wouldn’t skip oil changes and expect it to run forever, right? The same goes for your heating and cooling equipment.
Regular maintenance keeps your system running efficiently, which translates directly to lower monthly utility bills. A well-maintained system uses less energy to heat or cool your home. Beyond the money you’ll save, seasonal maintenance catches small problems before they turn into expensive emergency repairs that require urgent furnace repair or AC replacement.
Key Benefits of Regular Maintenance:
- Improved indoor air quality through clean air filters and proper airflow
- Protection of manufacturer’s warranty with documented professional inspection
- Prevention of unexpected breakdowns during peak heating and cooling seasons
- Extended lifespan of your HVAC equipment
- Peace of mind knowing your system is ready for extreme weather

Spring HVAC Maintenance: Preparing Your HVAC System
Spring is the perfect time to get your air conditioning system ready for summer. Start by replacing your air filters, which should be done every 1-3 months depending on your system and household conditions.
Head outside and inspect your condenser unit. Clear away any leaves, grass clippings, or debris that accumulated over winter. Make sure there’s at least two feet of clearance around the unit for proper air flow.
Essential Spring Tasks:
- Clean or replace air filters throughout your home
- Remove debris from outdoor cooling unit
- Check thermostat settings and replace batteries if needed
- Inspect visible ductwork for gaps or damage
- Clear condensate drain lines to prevent water damage
- Test your air conditioner before the first hot day arrives
This is also the ideal time to schedule a professional inspection with Girdner Heat and Air. Our HVAC technician checks refrigerant levels, tests electrical connections, and spots potential issues before they become major problems. Loose electrical connections are a fire hazard that only a licensed technician should handle. We also offer thermostat installation if you’re looking to upgrade to a programmable or Energy Star model.
Summer HVAC Care: Peak Performance
During summer’s heavy-use months, your air conditioning system needs extra attention. Check your filters monthly and replace them if they look dirty. A dirty filter forces your system to work harder, wasting energy and money while reducing airflow.
Keep an eye on your outdoor unit throughout the season. Trim back any vegetation that’s grown too close, and hose off the exterior fins gently if they’re covered in dust or pollen.
Summer Monitoring Points:
- Monthly filter checks during peak usage to maintain indoor air quality
- Keep outdoor cooling system clear of plants and debris
- Watch for leak signs around refrigerant lines
- Listen for unusual sounds like grinding or squealing
- Monitor indoor temperature consistency across all rooms
If your system struggles to keep up with the heat or your energy bills spike unexpectedly, call Girdner Heat and Air for air conditioning service. Our team provides emergency HVAC service when you need it most.

Fall HVAC Maintenance: Getting Your Heating System Ready
Fall hvac maintenance focuses on your heating system. Before temperatures drop, you need to make sure your furnace is ready to keep your family warm and safe. This is the time to prepare your HVAC system for months of continuous operation.
Start by replacing your air filters with a fresh one. Test your thermostat by switching to heat mode and making sure the furnace fires up properly.
Essential Fall Heating Preparations:
- Replace air filters before heating season begins
- Test furnace startup and listen for odd noises
- Check carbon monoxide detectors and replace batteries
- Reverse ceiling fan direction to clockwise for better heat circulation
- Inspect visible ductwork for gaps that affect air quality
- Schedule a professional tune-up to ensure proper operation
Professional fall hvac maintenance from Girdner Heat and Air includes checking your heat exchanger for cracks, testing safety controls, and inspecting your flue system. These aren’t tasks homeowners can safely check themselves, but they’re critical for both efficiency and safety. Our licensed technician can also lubricate moving parts and check gas pressure in your gas furnace to ensure it runs efficiently.
Winter HVAC Maintenance: Keeping Your System Running
Winter hvac maintenance is less intensive but still important for keeping your system running smoothly. Keep up with regular filter changes every month during heavy furnace use to maintain proper airflow and prevent breakdowns.
Pay attention to how your heating and cooling system performs. Cold spots in certain rooms, unusually high heating bills, or strange smells when the furnace runs all warrant professional attention.
Winter Care Essentials:
- Monthly air filter replacements during peak heating season
- Inspect vents to make sure everything is clear and unblocked
- Monitor system performance to catch issues before they become costly repairs
- Protect outdoor AC unit from winter weather and debris
- Schedule professional HVAC maintenance if you notice any problems
Professional HVAC Maintenance Tips vs. DIY Tasks
Homeowners can handle certain tasks safely, like changing air filters and keeping outdoor units clear. But professional inspection catches the problems you can’t see or safely check yourself.
A comprehensive annual maintenance plan from an HVAC technician includes inspection of electrical connections, refrigerant levels, heat pump operation, evaporator coil cleaning, and condensate drain line checks. These preventative maintenance checklist items help you stay ahead of problems and extend the lifespan of your equipment.
