Warning Signs That You Need a Heating and AC Repair Service

An HVAC unit will keep you cool in summer and warm in winter. Yes, we do get cold days in Garland! Several elements in an HVAC unit could go wrong and would need a heating and AC repair service. Warning signs include:

Evaporator Coil Is Frozen

A fan will remove warm air from a room and blow it over an evaporator coil. The coil contains a volatile coolant in a liquid state. As the warm air passes over the coil, it absorbs the excess heat from the air, and this turns the cold liquid into a warm gas. The warm gas is then pumped around the HVAC, first passing into a compressor and then a condenser. And then back around to the coil again.

If there is a coolant leak there will not be sufficient coolant in the HVAC unit to deliver enough cool air. A leak will need to be found, repaired and the coolant topped up. Low coolant levels will cause the evaporator coil to freeze.

The evaporator coil can also freeze if there is not enough air flowing over it. Replacing dirty air filters and cleaning the return air grill will improve airflow. Dirt and grime will accumulate on the evaporator coil can also cause it to freeze so it will need regular cleaning. The dirt acts as an insulating layer and reduces the transfer of heat from the warm air, causing it to freeze.

When the evaporator coil freezes, you should turn the HVAC off to allow the coil to thaw. Continued use will cause the rest of the components in the HVAC to work harder, increasing your energy bill and reducing its working life due to wear and tear.

Burned Out Compressor

After absorbing the heat from the warm air, the hot coolant gas passes through a compressor and is squeezed into a more compact and higher-pressure gas. The compressor can burn out if it is overworked. This is the case when the evaporator coil is frozen.

Dirty and Blocked Condensers

After passing through the compressor, the hot high-pressure gas next enters the condenser. The condenser is surrounded by cooling fins which help radiate the heat to the surrounding air. As it is located outside the home dirt or grime will settle on the condenser and cooling fins. This layer will slow the transfer of heat from the condenser, and it may burn out because it needs to work harder. Any dirt, moss, and weeds will need to be removed regularly.

Clogged AC Drain Line

Also located outside is the AC drain line. This is where any moisture from the warm air flows. Mold and mildew can grow around the drain and cause it to block. So can any wet leaves and dirt, if these gather around the line they will need to be cleaned. On a cold day, the AC drain line can freeze, if your HVAC unit stops working on a cold day, it may be worth checking the line to see if it has frozen. It could save you having to call for heating and AC repair service.

You Hear Odd Sounds

A bend or damaged fan may cause strange noises or vibrations to come from the unit. So can a worn-out belt. This may result in the fan not operating as efficiently as before, so less air can flow over the evaporator coil.

Is Your Unit Over Ten Years Old and Needs More Repairs?

If well maintained your HVAC should have a useful working life of between 10 to 15 years. If it needs to be repaired more frequently then it may be time to replace it. Over time it may be more difficult to find replacement parts and coolant for your older unit. A new model needs a large upfront investment but will be more energy-efficient and this will save money in the long run.
