When temperatures climb into the upper 90s and heat indexes push well over 100°, even a healthy air conditioner has to work harder to keep your home comfortable.
If your AC seems like it’s running nonstop but your house still feels warm, you’re not alone. Here are five of the most common reasons your system may be struggling during a Midwest heatwave.
- Your Air Filter Is Dirty
A clogged air filter restricts airflow, making it harder for your system to circulate cool air throughout your home. This causes your air conditioner to run longer, use more energy, and put additional wear on the equipment.
Tip: Check your filter monthly during the summer and replace it when it’s dirty.
- Your Outdoor Unit Needs Room to Breathe
Your outdoor condenser releases heat from your home. If it’s surrounded by weeds, bushes, grass clippings, or debris, it can’t do its job efficiently.
Keeping at least two feet of clearance around the unit helps improve airflow and overall performance.
- Your System Is Working Overtime
On extremely hot days, it’s completely normal for your air conditioner to run longer than usual.
However, if your home never reaches the temperature you’ve set, your system may need service. Low refrigerant, dirty coils, or worn components can all reduce cooling performance.
- Your HVAC System May Be Showing Its Age
Most air conditioning systems last around 12–15 years with proper maintenance.
If your system is older, you’ve had multiple repairs recently, or your energy bills continue to climb, it may be time to start thinking about replacement rather than another repair.
Our team is always happy to provide honest recommendations and help you decide which option makes the most sense for your home.
- Your Home May Be Working Against Your AC
Sometimes the problem isn’t your air conditioner at all.
Poor insulation, air leaks around doors and windows, direct sunlight, or high indoor humidity can all make your home feel warmer and force your system to work harder.
Simple improvements around the home can often make a noticeable difference in both comfort and energy costs.

Frequently Asked Questions
Is it normal for my AC to run all day during a heatwave?
Yes. During extreme heat, it’s common for your air conditioner to run longer than usual to keep your home comfortable. However, if it never reaches the temperature you’ve set or starts blowing warm air, it may be time to have it inspected.
What temperature should I set my thermostat in the summer?
Most homeowners find 72–78°F comfortable. Setting your thermostat dramatically lower won’t cool your home faster—it will only make your system run longer.
How often should I change my air filter?
Check your filter once a month during the cooling season. Most filters should be replaced every 1–3 months, depending on your home, pets, and allergies.
How do I know if I should repair or replace my AC?
If your system is under 10 years old and the repair is minor, repairing it is often the best choice. If it’s 15 years or older, requires frequent repairs, or struggles to keep your home comfortable, it’s time to explore replacement options. Envirotech is committed to providing honest recommendations based on your system and budget.
How can I help my AC run more efficiently?
Keep your air filter clean, make sure furniture isn’t blocking vents, keep the outdoor unit free of debris, and schedule annual maintenance to keep your system running efficiently.
Why is my upstairs so much hotter than my downstairs?
During extreme heat, it’s common for second-story rooms to feel warmer because heat naturally rises. Poor insulation, blocked vents, ductwork issues, or an aging HVAC system can all make the difference more noticeable. If the temperature difference is significant, it’s worth having your system evaluated.
Does Envirotech offer emergency AC service?
Yes! We have technicians on call 24/7 to help when your air conditioning stops working. If your system isn’t keeping up with the Kansas heat, give us a call — we’re here to help.
