Our winters may not bring harsh freezing temperatures, but a functional heating system is still a must for those chilly nights. At the same time, your air conditioning system plays a vital role year-round in our warm and humid climate. As an HVAC contractor serving locals with everything from heating repair to AC maintenance, we know how inconvenient and uncomfortable a system breakdown can be. In this post, we’ll cover key warning signs that your HVAC system—especially your heater—may be on the brink of failure. Spotting these issues early can save you from a total collapse and an unexpected repair bill.
Weak or Uneven Heating
One of the first indications of a struggling heating system is uneven heating throughout your home. If some rooms are cold while others are warm, your heater might be losing its efficiency. This could stem from problems with:
- A clogged air filter restricting airflow.
- A malfunctioning thermostat.
- Leaks in the ductwork.
These issues may seem minor, but if left unaddressed, they can strain your HVAC system and lead to more serious damage.
Frequent Cycling On and Off
Does your heater or air conditioner seem to run in short bursts, turning on and off repeatedly? This is called short cycling, and it’s a major red flag. For heaters, it can indicate issues such as a dirty flame sensor or an overheating furnace due to clogged filters or restricted airflow.
Strange Noises Coming From the System
Unusual sounds coming from your HVAC system are never a good sign. Keep an ear out for:
- Banging or clanging: This could mean a loose part in the furnace or blower.
- Whistling or hissing: This may indicate an air leak in the ducts or a refrigerant issue.
- Squealing or screeching: These noises often point to worn-out belts or motor bearings.
While occasional noises might be harmless, persistent or loud sounds usually signal deeper mechanical problems that need professional attention.
Rising Energy Bills
An unexplained increase in your energy bills is often a subtle indicator that your HVAC system isn’t performing efficiently. For heaters, this could mean the furnace is working harder to produce the same amount of heat due to issues like dirty burners or a failing heat exchanger. If your energy bills are climbing and your comfort is declining, your system may be nearing the end of its lifespan.
Age of the System
Even the best-maintained HVAC systems have a limited lifespan. Furnaces typically last 10-15 years, while heat pumps can last around 10–15 years in our coastal climate, where salt air and humidity can accelerate wear. If your system is approaching these benchmarks and experiencing frequent repairs or inefficiencies, it might be time to consider a replacement before a complete failure occurs.
