Understanding HVAC Guidelines

Understanding HVAC Guidelines

Once I purchased my first home, I realized that I needed to do my part in caring for my home appliances. In addition to reading the user manuals for my kitchen appliances and state-of-the-art plumbing system, I realized that I also needed to do a little research about HVAC. Because I had no experience with HVAC systems, I called out a professional to teach me a thing or two. It was fascinating to talk with him, and I was able to take notes about all kinds of important topics, such as maintenance, troubleshooting, and even shopping for a new system. This blog is all about understanding HVAC guidelines.

What Can You Expect From Air Conditioning Tune-Up Service?

Is your air conditioner ready for the summer? You can only be sure after a thorough tune-up by a professional AC technician. This type of AC servicing aims to identify any emerging issues and fix them to return the AC to peak efficiency. It has several benefits, among them ensuring your AC works as expected and your power bills remain low. What can you expect when AC services come for air conditioning tune-up?


The first step is inspection. The technician inspects different elements closely using sight and tools. They work to check if:

  • Electrical connections are intact and have not been dislodged by vibrations. 

  • The refrigerant line is free of damage and cracks. 

  • Indoor coil and blower assembly are cooling and moving air in the expected volumes. 

  • The fan blade is rotating and well-balanced to avoid falling off or cutting into other components. They will also check the blade bearings for wear and tear.

  • Duct supply and return are moving air in and out of the house as expected. 


Air conditioning systems become less efficient when dirt and grime build up in different components. It impedes airflow, making the AC work harder and use more power. During a tune-up, the technician will:

  • Clean the condenser coil that is outdoors and exposed to dust and debris. 

  • Change the HVAC filters. Clogged air filters are the biggest cause of AC inefficiency. You should replace them at least twice a year.

  • Unclog the condensate drain. They flush the drain line free of the dust and debris to avoid spillovers from the line.

  • Clean the outside condenser. The technician can also wax the condenser to give it a better look.

Testing and Measuring 

AC services test and measure components that work with fine calibration to ensure their original installation and settings. The AC services will:

  • Test the electrical wiring for correct current flow.

  • Test the thermostat is tested for correct temperature reading. They also check if the battery has enough power. 

  • Test the thermal expansion belt (TXV) for the proper regulation of refrigerant flow. 

  • Test the service valve for refrigerant leaks. 

  • Evaluate the pressure of the refrigerant coming into the condenser to ensure the condenser is handling the right volumes.

  • Check the state of the primary and secondary motors. 

  • Test and measure the electric current running in the fan motor is at expected voltage and amperage.

  • Measure the temperature difference at the supply and return to ensure the whole AC works as expected. 

Would you like to see your air conditioning working at peak performance in summer? Talk to AC services about a tune-up. A company like Turner Services Co. can provide more information.
