Warnings Sign That There May Be Problems

A service will give the HVAC a good spring clean and ensure that any minor issues do not become major ones. Without one, you will increase the risk of needing a visit from a heating and AC repair company.

Potential HVAC problems could show themselves in many ways.

  • Larger than anticipated energy bills.
  • Reduced airflow.
  • The HVAC not supplying enough hot or cold air.
  • You notice odd smells coming from the HVAC.
  • Hearing strange noises emerging from the HVAC.

You Start to See Frost and Ice and Frost Forming on the Evaporator Coils

Frost and Ice forming on the coil is not a good sign. The evaporator coils are a vital component in your HVAC, as it absorbs the excess heat and humidity from the air in your home. Fans blow the warm air from your home over the coil.

The heat is extracted from the warm air by the coolant in the coil. The coolant is pumped around the HVAC by the compressor unit, passes through the condenser and cooling fins located outside your home. Here the heat is radiated to the outside air and the coolant continues its journey back to the coils.

Any restriction of the warm air been blown over the coils could cause frost and ice to form. These restrictions can be due to dirty filters or faulty fans not blowing enough warm air.

Low coolant levels can also cause frost and ice to form as well as dirt layers forming on the coil. Ignoring the frost and ice building up could lead to a call to a heating and AC repair company.

The Condenser and Cooling Fins Are Dirty

When the coolant reaches the condenser and cooling fins the excess heat from inside your home is radiated to the outside air. As they are located outside a layer of dirt and grime will accumulate on them. This dirt acts as an insulating layer and reduces the rate at which heat is radiated. This will reduce the cooling effect of the HVAC.

The condenser and cooling fins need to be cleaned regularly, and this is also part of a regular service. Moss and weeds can grow on the condenser and fins. These will also need to be removed as they restrict the flow of outside air over them, further reducing the cooling effect. Without cleaning, the condenser could overheat and burn out, leading to a visit from a heating and AC repair company.

Uncalibrated and Poorly Positioned Thermostat

An uncalibrated thermostat or poorly positioned one will increase your energy bills. One placed in direct sunlight or near an open window will miscalculate the temperature and cause the HVAC unit to work harder than it needs.

Close Windows and Doors

The best way to keep your home cool in the summer with the air conditioner on is to keep your windows and doors closed. It is also the best way to keep your room warm in the winter. Open windows and doors will create different temperature regions in your home and cause the HVAC to work harder to compensate.

Heating and AC Repair Company May Need to Check the AC Drain Line

People often forget the AC drain line, if it is blocked for any reason, it may cause the HVAC to shut down. Any water from the warm humid air is collected in the drip pan. This then flows outside via the AC drain line. Moss and Mildew could grow inside the line and block it.

The water now has nowhere to exit the HVAC, it builds up in the drip pan and then overflows into the HVAC and then onto your floor. Any increased humidity and even the smell of mold may be explained by this. Before you ring a heating and AC repair company it may be worth checking to see if the drain line is blocked.

As you can see a problem with one component can impact others. A faulty component will cause the other components to work harder to compensate. Overworked components use more energy and are more likely to overheat, burn out, and need a visit from a heating and AC repair company.
