Most homeowners know at some level that HVAC tune-ups are something they are “supposed” to do. However, many people delay an HVAC tune-up because they do not entirely understand what it is and why it’s so important. In this article, we will explain some of the critical elements of an HVAC tune-up, why it’s necessary, and what maintenance procedures it includes.



An HVAC tune-up gives homeowners the benefits of an HVAC system that is working optimally. In the summer, that means their home is cool and comfortable, and the air conditioner is working as efficiently as possible. Regular HVAC tune-ups can provide homeowners with peace of mind and reduce the chance of a breakdown or costly repairs.

Think of an HVAC tune-up as being similar to a regular dental checkup or wellness exam. Consistent HVAC tune-ups address any issues before they turn into significant, expensive repairs or worse. In fact, regular maintenance can extend the life of your HVAC system. When a professional technician conducts your HVAC tune-up, there are numerous things they will be checking and looking for simultaneously.


Good home maintenance dictates that your HVAC system should go through a thorough HVAC tune-up, ideally twice per year (at the beginning and end of the air conditioning season). We’ll begin with the two tasks you should be performing the most — the others are best left for HVAC professionals during the tune-up.

Change the Air Filter: You probably know that you need to change your air filters regularly to maintain the air quality in your home and the proper functioning of your HVAC system, especially if you have pets

Clean the Condenser Coils:  Dirty condenser coils are an inefficiency in your unit, making your utility bills skyrocket and your air conditioner work that much harder. 

Air conditioner condenser coils are responsible for moving warm air from your home to the outside. In Arizona, condenser coils are typically located outdoors in the condenser unit. The outdoor location makes the condenser coils susceptible to dirt, debris, and dust that can interfere with their proper function, especially during the monsoon season. Check the condenser coils yourself in-between HVAC tune-ups to be sure they’re clear of dirt and debris.


Lubricate Moving Parts: Lubrication is one of the most critical parts of an HVAC tune-up. Lubrication reduces friction and heat build-up, improving the energy efficiency of your air conditioner. 

Check All Belts: During an HVAC tune-up, the motors are evaluated and lubricated.  The HVAC technician will also check the condition of the belts on belt-driven motors. If a belt is suffering from wear and tear, a simple replacement that will go a long way toward preventing potential HVAC trouble and more complicated repairs in the future.

Check Coolant Levels: Checking the coolant levels during your HVAC tune-up serves multiple purposes. The professional will add coolant if necessary. Lower levels can indicate a potential leak in pressure ports, tubing or connections. If there is indeed a leak, it must be repaired properly to ensure the efficient and continued functioning of your HVAC system.

Check AMP Drawer: Electric bills during the Arizona summer can soar, which is why. checking the amp drawer is critical to making sure that the HVAC system is working efficiently. This check helps eliminate unnecessary energy consumption and lower utility bills while maintaining the well being of the air conditioning unit. During your HVAC tune-up, a technician will use a special instrument to check that all electrical components of your system — big and small — are working correctly.

This is by no means a comprehensive list of all of the things a technician will be doing and checking for over the course of your HVAC tune-up, but hopefully it is enough to give you a good idea of the types of issues that can be addressed and the importance regular HVAC tune-ups to extending the life of your HVAC system.
