How Often Should I Have My System Inspected?

Just like your car requires regular oil changes and inspections to keep running, your heating and air conditioning systems need routine inspections to keep your home comfortable.


What Can I Expect from a Maintenance Appointment?

During maintenance appointments, your service professional will thoroughly inspect your entire system, run a safety check, change any filters, lubricate all moving parts, clean dirty components, check the thermostat, test the airflow and ductwork, and identify any problem areas with your system.


Benefits of Regular Maintenance

While it is often forgotten, routine maintenance is crucial to maintaining healthy heating and air conditioning systems.

The benefits of regular maintenance include:

  • Increased efficiency: Dirty, overworked HVAC systems have to work much harder and use much more energy to adequately cool a home. By maintaining all necessary components, your HVAC systems don’t need to work nearly as hard, which means they consume less energy.

  • Lower energy bills: Routine maintenance increases your systems efficiency, which lowers your energy bills.

  • Reduced chance of breakdowns: Maintenance allows a service professional to identify and take care of any problem areas with your system, so you don’t have to worry about any unexpected breakdowns in the future.

  • Longer lasting equipment: Routine maintenance can double the lifespan of your HVAC systems by keeping them in the best condition possible.

  • Improved air quality: Improved airflow, clean ducts, and new filters all make for a home full of fresh, clean air.

  • Enhanced comfort: Say goodbye to reduced airflow, malfunctioning parts, and leaking ducts when you have a service professional maintaining your system. Maintenance ensures each room in your home is evenly cooled or heated.

  • Peace of mind: Knowing that your HVAC systems are properly cared for and prepared to keep your home comfortable all year long helps you rest easier.

The benefits of preventative maintenance are far too good to ignore. Don’t put off scheduling an appointment any longer.

Called in this morning when I found out my AC is not blowing cool air. Our business can not go without running air conditioning all the time. I explained this to Sasoun and he told me they're in the area and will be checking out as soon as they are done with the other job. He came and fixed our AC in no time. He was honest and friendly. I'd definitely recommend their business for their services and good price.

Excellent service and quality workmanship!!! I called Sasoun in desperation as the AC unit for one of my customers stopped functioning while we were doing some work at their house. It was a Friday night at 4:30pm when I called him. He was already home, but made it a point to leave the comfort of his home and meet me at 7:30pm at the client's home to get the job done! He saved me that night and I was so impressed by his knowledge and clean/efficient work. I would highly recommend Sasoun and his team! Give them a call!!! Very reasonable and honest guys!

Calstar's owner was very responsive and did a thorough inspection of my AC. Before him, I had an inspector come from my home warranty and did a horrible job of not finding the cause of the AC blowing air and spent more time selling me a brand new AC. I had to seek second opinion and Calstar was first to respond. He found the broken part which was the capacitor and that I was low on freon. He also gave me an honest assessment of the life of my AC. I appreciate his thorough inspection and quick turnaround to fix the problem. My AC instantly worked and it's been over a week and it's working perfectly fine. I'm glad I called them and will use them again for any AC repair or assessment needs.
