If your air conditioner seems to be running nonstop, your home won’t cool below 75 degrees, or your energy bill has suddenly skyrocketed, you’re not alone.
During extreme heat waves across Chicagoland, HVAC systems are pushed harder than at any other time of year. When temperatures climb into the 90s with high humidity, even healthy air conditioning systems have to work overtime to keep homes comfortable.
At Alltech HVAC, we’ve been helping homeowners throughout Chicago’s North Shore and Northwest suburbs stay cool for years. As a family-owned and operated HVAC company, we understand the unique challenges our climate presents and proudly back every service with the Alltech Guarantee.
Whether your AC needs a simple repair, preventative maintenance, or it’s time for a replacement, knowing what your system should—and shouldn’t—do during a heat wave can save you money and prevent costly breakdowns.
One of the most common questions we receive every July is:
“My AC never shuts off. Is something wrong?”

During an extreme heat wave, it is perfectly normal for a properly functioning air conditioner to run for long periods.

Turn the system off and call a professional before damage becomes worse.
None of these sounds are normal.
Homeowners can dramatically improve cooling performance by:
Small improvements reduce strain on your HVAC system and improve energy efficiency.
Humidity is just as important as temperature.
If your home feels sticky even though the thermostat says 72°, your system may not be removing moisture effectively.
Proper humidity control:
