7 Reasons Your HVAC System is Freezing Up | Heating and AC Repair in Fort Worth, TX

There are many reasons why your HVAC system could become faulty overtime. They may have suffered from structural damage or glitches due to problems in external temperatures. If your AC isn’t blowing cold air and is making plenty of noise,  then it’s probably freezing up. And while you should call someone for heating and AC repair in Fort Worth, TX immediately, read up here on some possible issues with your HVAC system that could be the culprit.

The following list will do sufficiently to help you stay informed on what your HVAC system does and doesn’t do. After all, it’s always a good idea to acquire some machine learning.

1.   Clogging Due to Dirty Filters

Clogged air filters are probably the main cause of any faulty HVAC system. Some HVAC issues in this list could actually just be due to a clogged system. Dust and debris could collect in the filters, which may cause a huge strain on the HVAC and block out cold air.

If you’re wondering why your energy bills are so high, your HVAC system could be the reason as it may be putting more effort into heating/cooling your room. The fans will have to work harder to retain cool air. Apparently, inoperative machines in the house can increase utility bills up to 15%.

You will have to contact someone for heating and AC repair in Fort Worth, TX to get your furnace fixed in time. If you don’t take action, clogged filters could possibly spread dust allergies and other bacteria in the room because the dust that should’ve been filtered out is being blown into the room. Poor indoor air can weaken your lungs overtime, causing serious health concerns like asthma.

You should immediately take your HVAC system for heating and AC repair in Fort Worth, TX because if the furnace suffers any more damage, it will cost you a fortune to get fixed.

2.   Refrigerant Leak

The refrigerant in your HVAC system is responsible for temperature and pressure changes. A leak in the AC coils can cause the system to freeze over. Refrigerant leaks can come from evaporator coils – which rub against each other, condenser coils – due to holes in the U-bends, and refrigerant line sets that may leak because of broken joints in the HVAC system.

However, refrigerant leaks are rare because your AC system doesn’t actually consume the refrigerant. If you’re adding a new refrigerant every now and then, the real problem is a leak somewhere, for which you need to get in touch with heating and AC repair in Fort Worth, TX.

 3.   Malfunctioning Thermostat

There could be a glitch in the thermostat or room sensors that may cause your HVAC system to overwork. The controls of your HVAC system are responsible for heating, cooling, and humidity in the room. A faulty thermostat can cause your air conditioner to work constantly despite of low temperatures.

Your room sensors may not be giving the right signals to your HVAC to turn off even when the indoor temperature doesn’t need heating/cooling. If the AC runs constantly, the condenser coils can freeze up shutting down the whole system. You should get your thermostat either replaced or recalibrated for which, you should check out a heating and AC repair in Fort Worth, TX.

4.   Drain Blockage

Without a proper drainage, all the condensed water remains trapped in the HVAC system, and may freeze overtime because of the cooling process. A drain takes away the vapor-turned-liquid water from the coils and out into a drain pan.

If the coils end up freezing, the entire drain can become clogged, which may cause major freeze damages. More and more ice collects on the coils and freezes the entire system. Before that happens, make sure you get help for heating and AC repair in Fort Worth, TX. Additionally, debris like twigs and leaves, and in rare cases even pest activity can block your AC drainage.

5.   Low Outdoor Temperature

This may sound surprising but sudden coldness and hotness in outdoor temperatures can put even more strain on your HVAC system. It will have to diligently pull in air and maintain optimum indoor temperatures. The outdoor temperature should be around 70-100 degrees and indoor should be under 80 degrees. If it’s too low, the evaporator coils of the HVAC system may freeze up. At times, your AC will shut off completely and you will have to restart the whole system.

However, installing a thermostat with a lower set point may give you good cooling inside but the walls may start sweating from the exterior, which can cause molds to grow. You can open your curtains and doors for ventilation or use your AC on fan mode for a temporary fix. However, to maintain the temperature above 70 degrees, it’s best to call up a contractor for heating and AC repair in Fort Worth, TX to resolve the problem.

6.   Fan Problems

The fan attached to the evaporator unit might not be working properly. If there is no airflow and very little cooling by the HVAC system, then the fan motor may be damaged, burnt, or may have loose connections. If the air around the evaporator is blocked or clogged, the fan will not function either. Make sure you don’t have anything placed too near your evaporator.

Additionally get your evaporator coils cleaned and washed. For a full service, call up a consultant for heating and AC repair in Fort Worth, TX.

7.   Reversing Valve Problems

Reversing valves rarely have problems. Still, if there is a problem, there could be 3 possible reasons; the coils are broken, there is an internal leak in the valve, or the valve is jam-stuck in cooling/heating position. For any of these reasons, you should call in someone for heating and AC repair in Fort Worth, TX to fix the coils and the compressor.

This detailed guide will help you diagnose precisely why your HVAC system is acting up. Once you know what’s wrong with your HVAC unit,  get in touch with a contractor for heating and AC repair in Fort Worth, TX for further assistance.
