If you live in Murrieta, you already know that your HVAC system is the backbone of home comfort. When it breaks down, everything stops. Whether it is the middle of a summer heatwave or a cold morning in December, knowing the most common HVAC repairs can help you spot issues early and save money before they turn into major headaches.
At Airtime Heating & Cooling, we have seen it all. Here are the top HVAC problems that show up in homes across Murrieta and how to handle them before they hit your wallet.
1. Dirty Air Filters
This is the easiest fix on the list, yet one of the most common reasons for service calls. A clogged air filter restricts airflow, forces your system to work harder, and can cause uneven cooling or heating throughout your home. Changing your filter every one to three months keeps your system efficient and helps your air stay clean.
2. Leaking Refrigerant Lines
If your AC is running but not cooling, you could have a refrigerant leak. Refrigerant is what allows your system to remove heat from the air, and even a small leak can tank performance. Not only does this reduce cooling power, but it can also damage the compressor over time. Only a licensed HVAC technician can safely locate and repair these leaks.
3. Dirty Condenser or Evaporator Coils
Murrieta’s dust and pollen can build up fast, and your coils are prime targets. Dirty coils reduce your system’s ability to transfer heat, which leads to poor cooling and higher energy bills. Routine maintenance, including professional coil cleaning, keeps your system running like it should.
4. Electrical Problems
From loose connections to faulty capacitors, electrical issues can cause intermittent performance or complete system failure. These problems are not just inconvenient; they can be dangerous. If your HVAC system is tripping breakers or not turning on, schedule a professional inspection right away.
5. Issues with the Ignition System or Pilot Light
If you have a gas furnace, ignition problems are common. A dirty sensor, worn igniter, or faulty pilot light can all keep your furnace from firing up. This is not something you should attempt to fix on your own. A trained technician can safely diagnose and repair these issues before they leave you without heat on a cold night.
6. Thermostat Problems
Sometimes the issue is not your HVAC system at all. A faulty thermostat can give inaccurate readings, cause short cycling, or prevent your system from turning on. Upgrading to a smart thermostat can improve temperature control and efficiency, especially during Murrieta’s unpredictable seasonal swings.
7. Tripped Breaker or Blown Fuse
If your HVAC suddenly shuts off, check the breaker box first. A tripped breaker is often the result of an overworked system or a dirty filter. Resetting it may get you by temporarily, but recurring trips mean something deeper is wrong. An inspection will determine whether your system is drawing too much power or if there is a wiring issue that needs attention.
8. Blower Motor Problems
The blower motor moves air throughout your home, and when it fails, airflow drops to almost nothing. Common causes include worn belts, debris buildup, or electrical issues. Early warning signs include weak airflow or strange noises. Regular tune-ups can help prevent blower failures before they happen.
9. Drainage Issues
Your air conditioner produces condensation as it cools the air. That moisture drains through a small line, which can become clogged over time with algae or debris. When that happens, water can back up and cause leaks inside your home. Clearing the drain line during regular maintenance is an easy way to avoid this mess.
10. Worn Out Parts and General Wear
Over time, even the best HVAC systems experience wear and tear. Bearings, belts, and motors wear down. When that happens, efficiency drops and noise levels rise. Preventive maintenance keeps your system from reaching the point of failure, saving you from costly emergency repairs.
Why These Repairs Happen So Often in Murrieta
Murrieta’s hot summers and mild winters put year-round stress on HVAC systems. Dust, high pollen counts, and long cooling seasons mean your system rarely gets a break. Routine maintenance is not just recommended; it is essential for keeping your unit efficient and avoiding expensive breakdowns.
At Airtime Heating & Cooling, we recommend two seasonal tune-ups each year: one before summer and one before winter. That schedule gives you peace of mind that your system will start up strong when you need it most.
