Regular servicing of your HVAC and a deep clean once a year is recommended. Why? Well, it’s simple. Regular maintenance keeps your system free of dirt and debris and ensures optimum functionality. There are common winter HVAC problems that occur, regardless of regular inspections and maintenance. Let’s take a look at 5 of the most common winter HVAC problems.
1. Ice & Frozen Pipes
Snow is rarely a problem for HVACs in Athens, GA. However, low temperatures and ice can cause issues. Pipes and coils can be prone to freezing in lower temperatures as they are continuously surrounded by moisture. When pipes and coils freeze, continuous water flow can be obstructed. Ultimately, such an obstruction affects the functionality of hydronic systems, such as hot water heaters and steam radiators. Prolonged periods of ice blockages may cause damage to the unit.
In addition to this, frozen water expands and causes a build-up of pressure in the pipe. Over time, the pipe will rupture. If you think your HVAC pipes may be frozen it’s important to get it checked out by a professional immediately. By jumping on the issue, you might be able to avoid any significant damage to the system.
2. Uneven Temperature
Uneven temperatures throughout your home can be more noticeable during the winter than in warmer months. Cool spots aren’t just unpleasant, it’s a waste of energy. Some causes of uneven household temperatures may be poor insulation or old window and door seals. In some cases, blockages in the vents or ducts of the HVAC may be to blame. These can easily be cleared out by a professional who knows their way around the system.
3. Frozen Heat Pump
Heat pumps are an effective way to heat a home evenly and efficiently. The external unit of the heat pump is attached to the exterior of the house and can be prone to breakdown due to low temperatures and a build-up of ice. Like a freezer, a heat pump needs to be able to defrost completely to work efficiently. If the coil and fan become blocked by ice or frost it can stop functioning. Most heat pumps come with an automatic defrost setting. In cases of a heavy build-up of ice, however, this function may fail and ice will need to be removed manually.
4. Blocked Filters
With winter comes an increase in HVAC use. More frequent use can mean filters becoming clogged sooner. As air circulates through the HVAC, the filters are designed to trap any dust particles or dirt suspended in the air. Over time, a gradual build-up of dust and dirt will partially block the filters, reducing HVAC efficiency. If the filters become blocked completely, your HVAC may stop working altogether.
5. Damaged Thermostat
Sometimes the unit itself is working fine and the thermostat needs maintenance. A broken thermostat will not control the air temperature correctly and will reduce the efficiency of the unit. If you think your thermostat needs rewiring or replacing, it is vital that you consult a registered electrician or HVAC technician.
Many winter HVAC problems can be resolved easily by a professional. Leave it up to the experts to restore warmth and energy efficiency in your home.
