This essential HVAC tune-up checklist covers your heating and cooling system’s essential maintenance care needs. Routine HVAC Maintenance aids with:

  • Better energy efficiency
  • Saving money on utility bills
  • Improving the performance of the heating system
  • Better indoor comfort
  • Solving minor issues to help avoid breakdowns during extreme weather.
  • The overall safety of the heating system and risks to air quality
  • Increases the HVAC system’s service life
  Schedule an air conditioner tune-up soon because you may have forgotten how hard your HVAC unit works to keep you comfortable all year. You may feel like it’s an unnecessary expense, especially if your air conditioner is new; however, the cost of replacing multiple components or a whole AC unit is hefty. Preventive maintenance is an investment in your overall comfort and aids in keeping your energy bills low. This blog will explain the benefits of preventive maintenance and its importance to your air conditioning system’s long-term health. We’ll also go over what happens in an air conditioner tune-up and how you can save money on this and other services.

What’s A Tune-Up?

A pre-season tune-up is when a certified technician evaluates your HVAC system to ensure any HVAC issues are corrected. Your technician will begin with a physical inspection of your indoor and outdoor units. This list of tasks includes some of the following tests and treatments:
  • Testing pressures and diagnosing leaks
  • Checking refrigerant levels or leaks. 
  • Tightening loose fittings
  • Lubrication of components
  • Inspecting and cleaning coils and condensate pan
  • Inspecting ductwork 
  • Testing the thermostat 
The pre-season tune-up is when technicians will bring any problems to your attention and recommend any part replacements or repairs needed to complete your HVAC system optimization.

The Benefits of HVAC Tune-Ups

Why is an air conditioner tune-up so important? If you want the AC to perform at its best, it should receive regular annual service. There are several reasons to request a tune-up.  It’s important to have your system serviced each spring to perform the best. Air conditioning systems work extra hard to beat the heat of Summer and manage the humidity. It’s best to have an air conditioner tune-up every spring.  We also recommend a tune-up for furnaces in the fall before the heating season begins. If you have a heat pump, you need two tune-ups yearly because they work year-round and require extra care.

Tune-ups can aid with:

  • Lengthening your AC unit’s lifespan
  • Reduction in repair costs
  • Improved efficiency 
  • Lower energy bills
  • Increase home air quality
  • Increasing home comfort during the Summer.
  • Professional advice about the care of your HVAC system
  • Help in planning for your upgrades of equipment
If you’ve never had a tune-up before, you may want to put it off and limit expenses as much as possible. However, pay attention to signs that things aren’t working properly and schedule service to avoid serious damage in the future.  Read some of the issues to watch for below because they may indicate that there’s a problem in your HVAC equipment; a system tune-up will provide a solution:

Signs of Malfunction:

  • Poor airflow through your ducts
  • Air temperature inconsistencies.
  • Freezing of coils.
  • Unusual sounds from your units.
  • Continuous running of fan.
  • An unexplained spike in energy bills  
A tune-up helps address these issues and provides the opportunity to have an overall inspection of your equipment. If you experience a system failure, Reliability Heating & Air Conditioning provides emergency repair service.

Maintenance Checklist

After you’ve decided to conduct maintenance, it’s important to know what will be involved. This furnace tune-up checklist will cover essential care for all heating system components. The inspection also allows the HVAC tech to note any excess wear and tear signs. They may recommend repairs or changes in air conditioner usage to prevent further wear and tear. Ensure your trained HVAC professional:

Basic Care

  • Lubricates all moving parts
  • Tests and calibrates your thermostat, if necessary.
  • Changes the air filters.
  • Inspects ductwork to check for leaks of conditioned air
  • Checks lines for signs of leaks or oil.
  • Testing carbon monoxide levels
  • Cleans components.

AC Units

  • Checks the refrigerant levels
  • Checks your blower belt and blower motor performance
  • Checking and adjusting the fan belt tension
  • Inspecting and cleaning condensate drain
  • Cleaning the indoor and outdoor units


  • Inspecting the heat exchanger 
  • Testing the exhaust system
  • Inspecting and cleaning the burners
  • Verifying and adjusting gas pressure
  • Testing the ignition system
  • Checking connections to gas or oil lines
  • Inspecting and cleaning condensate drain
  • Cleaning the furnace


  • Tightens and tests all electrical switches and controls
  • Checks electrical wiring.
  • Checking the electrical Voltage and current
  • Tightening any electrical connections

Do You Need a Tune-Up Every Year?

The HVAC tune-up checklist is often an overlooked part of regular home maintenance. You may wonder if performing a tune-up each year is necessary. This thought is a common question, especially if their furnaces seem to operate just fine or if they’re relatively new. Your furnace experiences wear and tear during a heating season. Operation stresses components and hinders performance. Wear and tear decreases your system’s reliability and efficiency. Don’t skip maintenance if you didn’t notice any issues from last year! You may have new issues when turning your furnace on again. Unmaintained furnaces typically require more repair and don’t last as long as those receiving annual furnace tune-up care. Neglected furnaces risk frequent repair bills, high energy bills, and low air quality.  Some manufacturers require regular maintenance by a qualified HVAC technician as a warranty condition. You could be in danger of losing coverage due to equipment neglect! Consider furnace replacement if your furnace is more than ten years old or has had many repairs. Maybe you moved into a home and didn’t know whether you have a heat pump or a furnace. It’s the former owners who may have neglected routine maintenance.
