Hvac Repair Man Doing His Job

If it’s time for your annual HVAC checkup, you might be wondering about the process of HVAC repair and what an HVAC contractor can do for you. In this article, we’ll outline the basics of HVAC repair and why it plays an important role in reducing your energy costs. 

What is an HVAC System? 

HVAC is an abbreviation for Heating, Ventilation, and Air Conditioning. An HVAC system moves hot or cool, filtered air throughout your home or building to keep you comfortable when the temperature outside is not ideal. 

HVAC Repair and Maintenance Requirements

Most HVAC contractors recommend getting an annual HVAC checkup for maintenance and basic repairs. Depending on the level of use, age of the unit, size of the unit, and season, your maintenance requirements may vary. It’s important to stay on top of maintenance, otherwise you put yourself at risk for a sudden and expensive emergency. 

What Does a Typical HVAC Repair Service Include? 

A standard HVAC tune-up focuses on three phases: inspection, cleaning, and service. If problems are detected in your air conditioning or heating system during the service, the technician will correct them on the spot. 

Heating Service

The HVAC technician inspects the equipment, searching for signs of basic wear and tear in addition to broken parts. For heating elements, a technician may: 

  •  Inspect the ducts, vents, cabinets, refrigerant lines, and the area surrounding the unit for debris, leaks, or mold. 
  • Clean the condenser and evaporator
  • Wash drain lines and pans
  • Clean or replace filters 
  • Check humidity levels
  • Check thermostat controls 
  • Inspect the electrical components of the thermostat, replace batteries if needed
  • Lubricate moving parts 
  • Inspect fan, blowers, and blades
  • Replace worn pulleys and belts 
  • Examine the compressor and motor for signs of wear and tear  

Cooling Service 

In the heat of summer, the cooling elements of your HVAC system get a lot of use. A technician will begin their repair service by: 

  • Inspect the heating elements such as the heat exchanger, heat pump, ignition system, and burner
  • Clean or replace filters to allow for better airflow
  • Wash pans and drain lines
  • Test the thermostat and its controls for accuracy
  • Check for gas leaks if applicable
  • Replace worn-out parts, such as belts or pulleys 
  • Replace batteries in electric components 

Of course, any time of year is appropriate for an HVAC inspection. The most important thing you need to remember as an HVAC owner is that, like any appliance, an HVAC system will last longer and work more efficiently if you keep up with regular maintenance. Fixing basic repairs as they come up is preferable to an overdue system crash that requires heavy repairs or a full replacement.
