HVAC Maintenance Plans

Maintenance Plans

Assured Quality Heating & Cooling, LLC offers maintenance plans to keep your equipment running smoothly year round. With regular cleanings and preventative maintenance checks you’ll be more likely to experience uninterrupted heating and cooling throughout the year.

Some of our customers have asked us over the years, “If I sign up for a maintenance plan, does that mean I won’t need any repairs?” Unfortunately, the answer is “You will still need some repairs.” The good news is that, just like with your vehicle, if you perform routine maintenance and preventative checks you can avoid costly and catastrophic failures – meaning a lot less stress in your life.

Call us today at 704-492-1165 to learn more about options for maintenance plans and service agreements.

What Makes Us Different? We take our time and put care into everything we do. One of the most common mistakes we’ve found our competitors make is to ignore proper airflow. It’s one of the things we do on every job, because it is half the battle of getting your HVAC systems running properly.
