Temperature changes in your home can contribute to many adverse health effects ranging from discomfort and irritability to sometimes serious illness. The indoor air quality of your home is greatly affected by the care and maintenance of your HVAC system. Your HVAC is a complicated system with many components working together to keep your home at the optimal comfort level. Here are the top 6 reasons that your HVAC system may break down and the maintenance necessary to run an effective and efficient system.
- Tripped Breakers
Breakers are sometimes tripped by excess electrical usage which can cause your HVAC system to shut off. If your system stops running due to the breaker being tripped often, then consult a professional HVAC expert to diagnose the problem.
- Thermostat Issues (Broken or Wrongly Programmed)
Older thermostats that are not able to hold a setting correctly may be broken and need to be replaced to run more efficiently. Be sure to first check your batteries to make sure a new one isn’t needed to easily resolve the problem. Additionally, thermostats can sometimes be placed on the incorrect setting; you may have wanted “cool” but accidentally put the system on “heat”.
- Obstructed Condenser Unit or Clogged/Dirty Filters
If your system is obstructed by leaves, dirt or debris, then it may have a difficult time running efficiently. Extra strain placed on the operating system may lead to extra expenses and repairs. Keep the condenser unit free of any obstructions and also change out clogged or dirty filters according to the manufacturer’s instructions to keep your HVAC running to its optimal level.
- Refrigerant Leaks
A slow refrigerant leak can cause reduced cooling and a gradual decline in your HVAC system. Over time, the leak may release toxic gases or cause a complete system breakdown. HVAC experts are able to test for leaks and repair them to keep your home safe.
- Blown Capacitors
A blown capacitor can cause your HVAC system to stop cycling. You may have a capacitor problem if you notice your A/C is humming but the fan is not running. A blown capacitor is a common and usually easily fixed problem by an HVAC technician.
- Oversized or Undersized Unit or Outdated Design
If a unit installed in your home is too large or too small, it will run inefficiently for the space. The unit may cycle on or off too frequently or work overtime causing unnecessary expense and an uncomfortable air quality. Likewise, if you have done any remodeling or additions to your home, you may need to update your HVAC system to properly heat and cool your home effectively. It’s best to consult an HVAC design expert for possible system upgrades or ductwork changes. We recommend the professionals at Nelson Comfort for any HVAC questions or new installs.
Although there are many causes of HVAC problems, you can prevent almost all with regular system maintenance. Preventative maintenance is key to keeping your HVAC system running well and averting system failure.
