Schedule Service


If you’re like most homeowners, you don’t spend too much time thinking about your HVAC equipment—until you notice a problem. Then, as the AC shuts down and your home heats up, your HVAC system is the only thing on your mind. 

Whether you’re dealing with a minor issue like a clogged filter or a major concern like a system breakdown, the expert team at Greencat can help. We offer professional HVAC maintenance and repair services to homeowners throughout all of California, including those in Los Angeles, Orange County, Western Riverside County, and Western San Bernardino County, and can get your heating and cooling system back up and running in no time, whether it needs a little TLC or full-on, emergency HVAC repair.

HVAC Maintenance

No matter what type of HVAC equipment you have in your home, it needs regular maintenance. It’s typically recommended that you schedule a tune-up twice a year. Doing so will keep your HVAC system working optimally, leading to benefits like: 

  • Increased home comfort 

  • Higher energy efficiency

  • Lower energy costs 

  • Fewer emergency repairs

  • Longer system lifespan  

If it’s been a year or longer since your last tune-up, it’s definitely time to schedule maintenance. Other signs, like weak airflow coming from your vents, a strange rattling or humming noise, or unusually high energy bills, also indicate the need for maintenance. 

HVAC Repair 

HVAC tune-ups typically include simple preventative maintenance services like cleaning coils, replacing filters, and tightening loose parts. But they are primarily diagnostic. During your tune-up, your HVAC tech will inspect your heating and cooling systems carefully and take note of serious issues, like damaged parts that need to be replaced, or leaks that need to be sealed up. 

But you don’t have to wait for your regularly scheduled maintenance visit to roll around if you’re experiencing problems with your HVAC system and think you need heating or AC repair. You should call a trusted HVAC company for help if:

  • Your system isn’t keeping your home comfortable

  • You’ve noticed strange smells coming from your vents 

  • Your HVAC system is making a screaming, grinding, or clicking noise 

  • There are high humidity levels within your home

  • Temperatures are inconsistent between different rooms and floors

  • Your system is short-cycling (turning itself on and off frequently)

  • There is water or ice accumulating on any part of your HVAC system 

  • Your energy costs are much higher than usual 

An experienced HVAC technician will be able to tell you what’s wrong with your system and recommend the necessary repairs. Taking action quickly when you notice a problem is crucial, as ignoring an issue will only make it worse. By having it checked out right away, you may be able to catch a minor problem before it escalates, saving you from expensive repairs or a system breakdown.
