The winter season brings along with it harsh weather conditions that can create trouble for your HVAC system. Your HVAC unit is continuously under attack from freezing temperatures to frozen participation, resulting in potential damages. In addition, when an HVAC stops working, it can be challenging to diagnose the problem without professional help. Therefore, our Kingsport HVAC experts at Thompson Electrical Service share on the blog today seven ways HVAC units malfunction during the winter and how you can protect your HVAC unit investment from the harsh environmental elements.

1. Frozen Pipes

A drop in temperature can create ice inside pipes and coils that can cause your system to freeze over and cease to function. In addition, mechanical pieces such as hydronic systems like steam radiators and water heaters can fail when water ceases to flow through the pipes. Unfortunately, frozen pipes may burst due to excess pressure. Turn off your home’s water source and contact a professional Johnson City HVAC technician for repairs when this happens.

2. Uneven Airflow and Temperature

Homeowners who discover uneven temperatures throughout their home can quickly become irritated at their HVAC system. Unfortunately, the problem is common and requires a visit from our Tri-cities HVAC contractors to inspect your home’s ductwork and heating unit, ducts, and vents for debris and blockages so that your airflow remains unrestricted.

3. Malfunctioning Heat Pump

Homeowners with an exterior heat pump rely on them for warmth throughout the winter. Unfortunately, heat pumps can malfunction for multiple reasons, including coil blockages and broken fan motors. Furthermore, icy wind and snowfall can cause heat pump damage, resulting in a malfunction. Our Bristol HVAC experts explain that heat pumps’ coils and fans must not have frost on them to function correctly. Although many units have an automatic defrost setting to melt away ice, you may need to clear the ice manually.

4. Dirty Heater Filters

Overusing your home’s heater can cause filters to clog with dirt, dust, and other debris. In addition, the filter blockage typically decreases airflow and, therefore, reduces the warm air in your home. Many homeowners may not understand why there is less air circulation throughout their homes. Our Kingsport certified HVAC technicians can clear away filter obstructions and provide a new one if your unit’s current filter is permanently discolored or bent. Furthermore, our technicians will examine your system for any additional damages and ensure your heater runs smoothly before leaving your property.

5. Broken Thermostat

In some cases, your HVAC’s performance problem is not from unit mechanical malfunctions but in the thermostat’s electronics. Older thermostats may not correctly gauge your home’s indoor temperature, and it could cause fluctuating temperatures from room to room. Thus, our HVAC experts in Johnson City recommend replacing old thermostats for the best efficiency. If you are unsure about your thermostat, feel free to call our technicians. We can help homeowners repair faulty thermostat wiring if needed. Additionally, we can install a new thermostat and calibrate it for maximum energy efficiency.

6. Faulty Pilot Light

The pilot light is a small blue flame that remains constantly lit for easier heat access. Unfortunately, some heating units ignite after the pilot light turns on only. However, when the light dims or turns off completely, you should expect chilly temperatures indoors.  The most common faulty pilot light cases are from a dirty or damaged flame sensor. Our thorough Bristol HVAC technicians will clean the sensor and ensure the pilot light burns steadily before leaving your home.

7. Carbon monoxide leaks

As a homeowner, you do everything you can to keep your home safe and comfortable during winter. However, many homeowners are unaware of carbon monoxide dangers. Carbon monoxide is a poisonous gas that is nearly impossible to detect because of its tasteless and odorless state. Unfortunately, cracked heat exchangers or rusted heaters can contribute to carbon monoxide leaks in your home. Therefore, our Kingsport expert HVAC company recommends thoroughly inspecting your HVAC unit for damage and defects. Then, ensure your home has adequate ventilation to release carbon monoxide gases and examine your top range vent above the stove and your chimney for obstructions.
