1. Weak Airflow from Vents If your AC is on full blast but your home still feels muggy, your system could be struggling with blocked ducts, a failing blower motor, or worse. Weak airflow is never a good sign — it's like your system is whispering, “Help me.” 2. Strange Noises You’ve Never Heard Before Grinding, banging, squealing — no, it’s not a horror movie. It's your HVAC unit crying out for maintenance. Ignoring those sounds could turn a small repair into a full-blown replacement. 3. Higher Energy Bills with No Explanation If your power bill suddenly skyrockets, your HVAC could be working overtime due to a refrigerant leak, clogged filters, or a dying compressor. You shouldn’t have to choose between staying cool and going broke. 4. Hot and Cold Spots Around the House Inconsistent temps from room to room? Your thermostat, ductwork, or even zoning system might be off. These aren’t just comfort issues — they’re signs your system isn’t running efficiently. 5. The System is 10+ Years Old Even the best units wear out. If your HVAC is a decade old and showing any of the above symptoms, it's time to start thinking about a replacement before you're forced into an emergency install. Conclusion: Don’t Wait Until It’s Too Late Tennessee heat doesn’t take breaks, and neither should your HVAC. A quick tune-up now could save you thousands later. At AVU Air, we offer maintenance plans starting at just $99 a year, with priority service and exclusive discounts. πŸ“ž Call us today at 931-842-5392 to schedule your check-up. Stay cool, stay safe — AVU has your back.
