Common HVAC Problems: FAQs and Solutions

HVAC systems are an integral component of home life. They help keep your space warm and cozy all year round, but occasionally, issues arise that require professional help, while others can be resolved independently.

If your air conditioner always trips the circuit breaker, it could be an electrical problem leading to irreparable damage or something as straightforward as needing new air filters.

When dealing with HVAC issues, it’s essential to address them promptly – for top-quality AC repair in Thornton, CO consider reaching out to IMS.

1. Thermostat issues

Your thermostat is at the heart of your HVAC system, making its issues an immediate threat to the entire system. Issues may range from minor inconveniences to expensive repairs, depending on their cause.

If the display on your thermostat has gone dark, this could be because its batteries have run out or its fuse has blown. Replacing them and resetting the thermostat should solve this issue.

Another common thermostat issue involves sensors that don’t provide accurate readings. You can test this by comparing the thermostat display temperature with that of actual room temperatures – if one feels hotter or colder than indicated by its display, this may be indicative of inaccurate sensors.

An outdated or dirty thermostat can also pose problems, leading the system to short cycle or run continuously, diminishing energy efficiency. Therefore, cleaning its interior is advisable to keep everything running smoothly regularly.

Finally, an improperly mounted thermostat in your home can also pose problems. It is essential that it not be placed next to or directly in the path of any heat sources and should be at least five feet from the doors. If necessary, using a carpenter’s level may help correct this.

2. Water leaks

Air conditioning and furnace systems generate condensation during daily operation, which should drain through drain lines to exit the home and away from any potential hazards such as mold and structural damage to homes.

Unfortunately, if any lines become compromised, this condensation could leak back in and into homes, causing mold growth, increased water bills, and wasted energy costs.

If you suspect a water leak, it is best to seek professional assistance as soon as possible to find its source and repair it.

A qualified technician should check for damage to pipes or seals around vents and valves; in addition, they should look out for signs that indicate larger problems, such as rusty metal parts or structural flaws that indicate there is something amiss within the system.

Air filters are one of the more often ignored HVAC issues, yet many overlook it as a potential issue. A clean and fresh filter helps maintain proper airflow and reduce energy consumption, so ideally, they should be changed at least every three months – but more frequently if there’s excessive dust or smoke inside your home.

3. Uneven temperature distribution

An uneven household temperature can be a telltale sign of HVAC system issues. The heat pump, furnace, or air conditioner must circulate conditioned air throughout your entire house to be genuinely comfortable in all parts of it; otherwise, it will lead to hot and cold spots across your residence.

Uneven temperature distribution can often be resolved efficiently and effectively, and one of the primary culprits for it can be a dirty air filter, which restricts airflow and needs replacing. Make sure you change it frequently and select a model with high MERV ratings for the best results.

Another cause of uneven home heating could be that your ductwork is improperly sealed. Any cracks or leaks in your ductwork could force your HVAC system to work harder to get its job done, leading to an excessively warm or cool home environment.

Uneven home heating can also result from insufficient return air drops in your house. These drops transport any unconditioned air that enters your HVAC system for conditioning, so without enough return drops, your system may work overtime without ever even out the temperatures inside the home.

4. Noises

Sometimes, your HVAC system’s noises can reveal much about its condition. If you hear whistling, buzzing, or clanking sounds coming from it, this could indicate something is amiss with its mechanical parts – these should only be addressed by trained professionals. 

Worn bearings might cause squealing noises in an inducer or blower motor failing. A replacement should be scheduled immediately to avoid system collapse.

Rattling and banging sounds aren’t promising signs, either. This indicates a mechanical issue is present that will likely get worse quickly without immediate attention from you. It could be anything from dirty filters or access panels being present to being too small for your heating and cooling needs, forcing the unit to work harder than necessary and leading to premature wear and tear.

Preventative maintenance is, therefore, vital; this allows you to identify problems before they become major ones requiring costly repairs or replacements.
