Heating and Air Conditioning questions, answered by experts

There are a few reasons your AC is running but not cooling your room. Thermostat issues and dust and debris, which can clog your system, are common problems. It could also be a broken component, such as a compressor, blower fan, or evaporator coils. You’ll need to call a pro to diagnose the issue.

In many cases, replacing the entire AC system is a better investment than replacing a condenser or evaporator coil, as the labor and part prices can add up to a significant portion of the cost for a new system. Consult a licensed HVAC technician for an accurate diagnosis and recommendation.

An air conditioner’s watt usage depends on multiple factors, including the type of AC unit, its size, and how often you use it. With that said, most central air conditioners consume between 3,000 and 3,500 watts. Meanwhile, window AC units use 900 to 1,400 watts, and portable air conditioners consume 2,900 to 4,100 watts.

To extend your HVAC system’s lifespan, it’s crucial to keep up with maintenance. This includes changing filters and thermostat batteries, keeping the outside unit clean and clear of clutter, and lubricating moving parts. Watch out for leaks, mold buildup, and blockages to ensure your unit stays in good working order. Spotting these issues early can be the difference between a simple, wallet-friendly repair and an expensive replacement.

Yes, a mini split AC system can replace central air—and quite easily, too. Since mini splits don’t require ductwork, homeowners can convert their central air system to a mini split to save money and energy. Consult with an HVAC professional to learn more about the process of replacing your central air with a mini split.
