You depend on the HVAC system to efficiently cool the home during the hottest times of the year. However, when it suddenly stops operating normally, call a professional immediately to prevent the problem from worsening. Here are a few signs that indicate your unit needs air conditioning repairs.

When to Schedule HVAC Repairs

1. Strange Noises

The only noise an air conditioner should make is a low hum as it cools the house – any other type of sound can indicate an underlying problem. For example, banging may mean that there’s a loose part in the compressor, and rattling noises may warn you that there’s debris present in the outside unit. High-pitched squeals suggest a possible refrigerant leak, which can pose a serious threat to the unit’s long-term health and reduce its cooling ability.

2. Higher Bills

If your energy bills suddenly skyrocket, it can be because the unit is strained. The culprit is typically a dirty filter, which forces the system to work harder than necessary to cool the house. The strain can also stem from a failing part, such as a dying motor in the condenser. A lack of regular maintenance can also impact the unit’s efficiency, and it may need a quick tune-up.

3. Warm Air

If the unit starts blowing warm air, make sure the filter is clean, and the outdoor unit is clear of plants and debris. If these solutions don’t work, the evaporator coil or the return ductwork is likely dirty or damaged. ACs can also blow warm air when the refrigerant level declines. Low refrigerant indicates a leak, and it’ll need to be addressed by an air conditioning repair specialist immediately to prevent a worse problem.
