One room is freezing. Another feels like August.

AC Warning Signs: Know When to Call a Pro

Your AC is usually giving you warning signs before it stops working.

If your system is running nonstop, blowing warm air, making unusual noises, leaking water, or showing ice on the unit, it is time to take a closer look. Start with the simple, safe checks: confirm the thermostat is set to COOL, replace a dirty filter, and clear debris from around the outdoor unit.

If the problem continues, shut the system off and contact a qualified HVAC professional. Continuing to run an AC with ice, loud noises, or poor cooling can turn a smaller issue into a larger repair.

Demers Heating & Cooling provides fast, honest AC service throughout Harrison Township, Mount Clemens, and Macomb County. Call (586) 290-2665 or visit demersheating.com to book service.

𝗥𝗲𝗽𝗮𝗶𝗿 𝗼𝗿 𝗥𝗲𝗽𝗹𝗮𝗰𝗲?

Is it worth putting another repair into an older AC?
Sometimes, yes. Sometimes, that “cheap” repair just delays the inevitable.

Demers Heating can help you look at the age, condition, repair cost and efficiency of your system so you can make the choice that actually makes sense.

No pressure. Just an honest assessment.

When dirt, grass and debris clog the condenser, your system has to work harder — which can mean higher energy bills and more wear on your AC.

Keep the area around your unit clear, and if those coils are looking rough, give Demers Heating a call.
