We can expect winter to bring about a variety of HVAC issues that can cost more pennies than shivers. It’s important that you are well aware of the common HVAC issues that can plague homeowners. While a myriad of HVAC problems can develop in homes throughout the winter, you’ll be able to use your skills to identify and solve them. Here are the top HVAC winter mishaps.
Frozen Pipes
As temperatures decrease and ice accumulates, pipes and coils can eventually freeze over and begin to function poorly. Hydronic systems like hot water heaters and steam radiators can fail as frozen water prevents flowing. Homeowners can easily become frustrated when the heating breaks down due to freezing pipes.
Sometimes, frozen pipes burst due to pressure buildup. In these instances, you’ll need to teach homeowners how to turn off their home’s water and arrive promptly to repair the damage.
Malfunctioning Heat Pump
Some homes rely on warmth from exterior heat pumps. But chilly snowfalls and icy winds can damage these appliances, causing them not to perform correctly. Be aware that heat pumps suffer from a number of ills, including broken fan motors and coil blockage.
Throughout the winter, many heat pumps fail to defrost. For a heat pump to perform correctly, its coils and fan must be clear of frost. This fixture should be equipped with automatic defrost settings to melt away ice before thick layers form. If this setting is broken, you must clear away frost buildup manually.
Dirty Heater Filters
When heaters experience overuse, their filters are likely to become clogged with dust, dirt, and other debris. This blockage usually leads to decreased airflow and, subsequently, reduced warmth in the home. Ensure the motor and fans are working properly. Then, clear away any obstructions around the filter. If the filter is permanently discolored or bent, replace it with a new one. Then, check for other possible damages that could be preventing smooth running.
Uneven Airflow
Hot air falls in the winter months. Rising warm air is best circulated from floor diffusers and baseboard radiators. Knowing these trivial properties about air temperature can best optimize building heat to allow cool air to fall and the warm air rise.
Faulty Pilot Light
Some heaters fully ignite only after the pilot light turns on. This small blue flame usually stays lit at all times for better heat access. But when it fails to burn brightly or doesn’t burn at all, homeowners will face cold and uncomfortable temperatures.
The most common cause for a problematic pilot light is a dirty or damaged flame sensor. Clean the sensor and ensure a steady pilot light burn.
Carbon Monoxide Leaks
This poisonous gas is nearly impossible to detect due to its odorless and tasteless state. Many carbon monoxide leaks are due to cracked or rusted heaters. Inspect the heat exchanger for any defects.
Inadequate ventilation can block carbon monoxide gases from exiting the home. Check the chimney and above the stove for obstructions.
