Heating ventilation and air conditioning (HVAC) is one of the essential systems in your home, especially if you live in an area with extreme temperatures. A breakdown of this system can be costly and inconvenient. Financing your HVAC system through a home warranty can help alleviate some of the financial burdens of repairs.

There are many reasons an HVAC system can break down, but some causes are more common than others.
1) Clogged Filters
Air filters are essential to your HVAC system because they help remove dust, dirt, and other airborne particles. If the filters are clogged, it can cause the system to work harder than it needs to and eventually break down.
Some reasons for filter clogging include:
- Not changing the filter often enough
- Using the wrong type of filter
- Having pets that shed
To prevent this from happening, check and clean your filters regularly. Depending on your filter type, you may need to replace it every few months.
2) Malfunctioning Thermostat
Thermostats are designed to last for many years, but they can malfunction. A broken thermostat can cause your system to run constantly, leading to a breakdown. You can prevent this by having your thermostat serviced regularly.
Some types of thermostats include:
- Manual thermostats
- Programmable thermostats
- Smart thermostats
When a thermostat malfunctions, it can cause your system to run constantly, leading to a breakdown. You can prevent this by:
- Regularly servicing your thermostat
- Installing a new thermostat
- Using a smart thermostat
Smart thermostats have features like:
- Remote access
- Automatic adjustments
- Energy-saving modes
These features can save money on your energy bill and prevent a breakdown.
3) Leaking Refrigerant
Refrigerants are what make your air conditioner cool your home. So, it’s no surprise that a refrigerant leak is one of the most common causes of AC breakdowns. A leaking refrigerant reduces the cooling power of your AC unit and can cause long-term damage to other parts of the system.
Some ways to identify and fix a refrigerant leak:
- Check all connections and hoses for leaks
- If you see ice on your AC unit, that is a sign of low refrigerant levels
- Clean the coils and evaporator pan to remove any dirt or debris build-up
4) Blower Motor Issues
The blower motor is vital for circulating air throughout your home. If the blower motor isn't working correctly, your HVAC system won't be able to do its job effectively.
There are a few things that can cause blower motor issues.
One is a problem with the electrical supply to the motor. Another is a mechanical issue, such as a broken belt.
If you're having problems with your blower motor, it's best to call a professional HVAC technician. They may diagnose the problem and get your system up and running again quickly.
Blower motor issues can be prevented by:
- Regularly changing the air filter
- Make sure there is no debris around the blower unit
- Keeping the area around the HVAC system clear of obstacles
5) Lack of Preventive and Routine Maintenance
Preventive maintenance involves cleaning the coils and filters, checking the Freon levels, and more.
Routine maintenance is a service agreement between the homeowner and an HVAC company.
It’s typically an annual visit where the technician thoroughly inspects the system and makes any necessary adjustments or repairs. Not only does preventive maintenance help keep your system running smoothly, but it can also extend the life of your equipment.
