What Steps are involved in the Preventive Maintenance of HVAC Systems?

HVAC systems are a prominent part of all businesses and require maintenance services like all other systems. Improper and poor maintenance could lead to a 5% loss in working efficiency each year! The advantages you can get through regular inspection and maintenance of your HVAC system could be smooth operation, its lifespan increases, reduced energy bills, and the best air quality you can get, among other benefits. Most manufacturers suggest performing maintenance to your HVAC system twice a year, once before the winter season and once before the advent of summer, as it increases the lifespan of your HVAC system and avoids malfunctioning!

Components of HVAC Preventive Maintenance Process:

Whenever a competent technician visits you to perform HVAC Preventive Maintenance in Kansas City, MO, he will perform several tasks. Let us guide you about the details of all these tasks in particular: 

Checking refrigerant leaks and fixing them:

Refrigerant is an integral part of cooling in an HVAC system. If it is leaked, its cooling is compromised, and the energy bill is also increased. Upon identifying leakage in the coil, the expert technician uses two methods to fix it: applying the patch to the single small hole of the loop and replacing the lock if there are several holes.  

Cleaning the condenser coils to ensure adequate airflow:

Condenser coils are an essential part of an HVAC system. Their efficiency might be lowered because they can be contaminated by dust, dirt, or airborne substances. The technician will clean them thoroughly to ensure adequate airflow.

Checking gas connections for any leakages:

Gas leaks could be very lethal. These can result in malfunctioning of the HVAC system and severe health consequences, as inhaling them could be deadly. During preventive maintenance, the technician inspects the gas connections, tightens them, and performs maintenance if needed to ensure the system works smoothly without any leakages.

Inspection and tightening of all electrical connections

Checking safe electrical connections by a qualified technician is required during HVAC System Installation and during performing maintenance services. A faulty electrical connection not only threatens the HVAC system’s functionality but also poses serious electrocution hazards. During the preventive maintenance service, the technician wearing insulated safety gloves thoroughly checks the electrical connections and tightens them to ensure the system works perfectly and all the electrical hazards are nullified. 

Lubrication of all the moving parts:

The HVAC system comprises several moving parts. There appears to be friction between these moving parts with time, which can cause wear and tear. The maintenance technician lubricates all these moving parts to ensure smooth operation and nullify wear and tear.

Inspecting and calibrating the thermostat:

The thermostat is integral as it maintains the temperature in a workplace or a house. If it malfunctions, it results in sudden shutting off and on of the system resulting in poor functionality of the HVAC system and higher energy costs. The technician will thoroughly inspect and calibrate it, ensuring it works properly!

Cleaning or replacing the air filter:

A professional technician checks the air filters of an HVAC system thoroughly. These are often blocked by dust, pollen, and dirt. It is, therefore, necessary to clean and replace them; otherwise, the performance of the HVAC system is compromised. The technician performing the maintenance service will clean these air filters and, if needed, replace them, ensuring the smooth operation of the HVAC system.


The points mentioned above show the need and benefits of regular HVAC system maintenance. It ensures smooth operations and increases efficiency, reduced bills, healthier air quality, and increased lifespan of your system. Maintenance performed by a professional technician ensures that your HVAC system operates safely and efficiently throughout the year.

Hiring a professional technician for maintenance services is beneficial; he has all the necessary expertise and carries all the tools needed. Also, he can check electrical connections and calibrate your HVAC system’s thermostat, which you can’t. It is highly recommended that maintenance of an HVAC system must be performed twice a year. Once before summer and before winter, it adds longevity to your HVAC system.
