Signs Your HVAC System Needs a Professional Inspection

December 2, 2024

The health of your HVAC unit will determine how comfortable you are in the cold winter months and the hot summer months. That being said, HVAC units have a lot of parts and can be tricky to understand. Here are a few warning signs your HVAC system needs repair or replacement:

High Energy Bills: If your electricity bill has spiked for no apparent reason, it might be due to an HVAC system that is working too hard.


Weak Airflow: When your unit is running, the airflow from your vents should be a consistent even breeze. If you notice air is barely coming from your vents, your HVAC system needs to be inspected by your local HVAC technician.


Warm Air: Air temperature from vents should either be cold (when AC is running) or heated (when heat is running). Warm air won't heat or cool your house and is a sign of a damaged unit.


Unpleasant Smells: The air coming from your vents shouldn't have any type of smell. Musty air is likely from mold in your unit and a strong burning smell could indicate exposed electrical wiring. Both should be addressed immediately.


Age of System: If your HVAC unit is 15-20 years of age and you notice any of the above issues, your system has likely reached its limit and now is the time to replace your unit.


To ensure your HVAC unit lasts as long as possible, be sure to schedule a routine inspection once every six months. Call Davis HVAC Experts today to make sure your HVAC system is ready for the season ahead!

As we approach the hottest season of the year in Kentucky, homeowners start thinking about switching on their air conditioner for the first time in months. If your system has been unused all winter, now is the time to make sure it is ready for the demands of summer. Preparation can help avoid unexpected issues when you need your cooling system the most. There are a few steps every homeowner can take to ensure their system's longevity. There are a few things you can check before firing up your system for the year's first heat wave. Start by replacing your air filter to improve airflow and system efficiency. Check that vents are open and not blocked by furniture or dust buildup. Take a look at your outdoor unit and remove any debris, leaves, or overgrowth that may have accumulated over the winter months, as this could restrict airflow. These small adjustments can help your system run more smoothly as temperatures climb. Even when you check in on your unit at the start of the season, it is recommended to have professional HVAC inspections every year.

Rising energy bills can be frustrating, especially when your daily routine has stayed consistent. Many homeowners assume it is just the weather, but your heating and cooling system is often the real reason behind those higher costs as the weather shifts. When your HVAC system is not running efficiently, it has to work harder to maintain comfort, which leads to increased energy use month after month. Small system issues can have a big impact on the effectiveness and lifespan of your HVAC. Dirty filters restrict airflow, worn parts reduce performance, and unnoticed duct leaks allow conditioned air to escape before it ever reaches your living space. Over time, these problems put unnecessary strain on your equipment and drive up utility bills. At Davis HVAC Experts, we help homeowners get to the root of the problem. Our HVAC services are designed to evaluate your system as a whole, not just treat surface-level issues. During a professional HVAC system service, our team checks airflow, system efficiency, and key components to identify what may be causing your energy costs to rise. If needed, we provide honest HVAC repair recommendations to restore proper performance. If your energy bills continue to climb, it may be time to take a closer look at your system.
