How often should I have my HVAC system serviced?

For optimal performance and longevity, it’s recommended to have your HVAC system serviced twice a year—once before summer and once before winter. Regular maintenance helps prevent unexpected breakdowns and increases energy efficiency.

What are the signs my air conditioner needs repair?

Common signs include weak airflow, strange noises, unpleasant odors, increased humidity levels, and higher energy bills. If you experience any of these issues, contact ACS for an inspection.

What’s the average lifespan of an HVAC system?

With proper maintenance, most HVAC systems last 10 to 15 years. If your system is over a decade old and frequently needs repairs, it might be time to consider a replacement.

Do you offer financing for new HVAC systems?

Yes, ACS provides financing options to help make upgrading or installing a new HVAC system more affordable. Contact us to learn more about our flexible payment plans.

How do I know what size HVAC system I need?

An HVAC system’s size depends on your home’s square footage, insulation, and climate conditions. ACS can perform a load calculation to ensure you get the right-sized system for maximum efficiency and comfort.

How can I make my HVAC system more energy efficient?

Regular maintenance, cleaning air filters, using programmable thermostats, sealing ductwork, and upgrading to a high-efficiency system can all improve your HVAC’s energy efficiency. ACS can assess your system and recommend improvements.

Is ACS available for emergency HVAC repairs?

Yes, ACS offers 24/7 emergency HVAC repair services in Tucson. Whether it’s a breakdown in the middle of the night or on a weekend, our team is ready to restore your system’s function quickly.

What is ThuroTech?

ThuroTech is an exclusive ACS standard, made up of training processes, certifications, technician pride, and accountability. The ThuroTech process ensures optimal unit capacity, performance, and efficiency.

The HVAC industry is full of mainstream mistakes. Here’s a statistic from ENERGYSTAR, “recent field studies suggest that approximately 75% of installed cooling equipment may have an incorrect amount of refrigerant. Incorrect refrigerant level can lower efficiency by 5 to 20% and can ultimately cause premature component failure, resulting in costly repairs that could have been prevented.”

ACS put ThuroTech in place to uphold the proper techniques and practices on a CONSISTENT basis. Unfortunately, even when an HVAC company gets customer service, culture, and reputation correct, it doesn’t mean they are giving a proper installation. ACS doesn’t want your proper installation to depend on which Technician goes to your home, or how someone is feeling on the particular day they are at your home installing your new system.

Our goal is simple, to get you the system you paid for!

ACS is aiming to serve you with amazing customer service while providing an exclusive standard made of training, process, accountability, and pride. It’s called ThuroTech!
