Heating and Air Conditioning questions, answered by experts

If you know how to identify supply and return ducts, you’ll find that only the supply ducts will have dampers. Although your return ducts can have dampers, it’s not common. If you have one return duct that is pulling in too much air, adding a damper to it can help with overall system performance. However, dampers on return ducts are not a necessary addition for most homes.

When a compressor gets overheated in central air systems or heat pumps, it can still cool your home for a while until it eventually gives out. If the compressor is chronically overheated and no one addresses the root cause, it will create an incredibly expensive problem when your entire HVAC system breaks down and stops working altogether.

For most systems, an annual HVAC system service is more than enough. Some homeowners prefer a twice-a-year visit to ensure the system is ready for the upcoming summer and winter seasons. If you need to call an HVAC pro more often than this, it may be time to check if your system is getting old enough for a replacement.

The simplest indicator is how long it’s been since your last tune-up. You should schedule an annual AC tune-up each spring. Beyond that, there are multiple signs that your AC needs a quick check by a professional. These issues include higher-than-average energy bills, decreased air flow from vents, higher indoor temperatures, and an air conditioning unit that stays on all the time or frequently turns on and off.

There are many signs of a bad AC fan motor, including if the fan blades don’t spin when the AC kicks on or if they keep spinning when the AC is off. The AC fan cools down the condenser coil, so a faulty motor can also cause the system to overheat. Unusual noises in the exterior AC unit, including grinding or rattling sounds, may also be a sign that the AC fan motor is worn out.
