What Our Customers Are Saying

How often should I service my air conditioner or HVAC system?

It’s recommended to service your air conditioner and HVAC system at least once a year. For cooling systems, schedule maintenance before the summer season, and for heating systems, have them checked before winter. Regular maintenance helps ensure optimal performance and extends the lifespan of your system.

Common signs include:

  1. Unusual noises like banging, clicking, or hissing.
  2. Weak airflow or uneven cooling/heating.
  3. Higher-than-usual energy bills.
  4. Strange odors coming from the vents.
  5. The system is constantly running but not maintaining the desired temperature.

If you notice any of these, contact a professional technician promptly.

The duration of the repair depends on the issue. Minor repairs can take a few hours, while more complex problems, such as compressor replacement, may take longer. Our technicians strive to resolve issues as quickly as possible without compromising quality.

It depends on the age and condition of your system. If your HVAC unit is over 10–15 years old and requires frequent repairs, replacement might be more cost-effective in the long run. A new system can also offer improved energy efficiency and performance. Our technicians can assess your system and recommend the best option for you.
