HVAC tune-ups for furnaces, heat pumps, and AC

Quick answer

An HVAC tune-up is a yearly check-up where a technician cleans, tests, and inspects your furnace, heat pump, or AC so small problems get caught early. ENERGY STAR recommends pre-season check-ups: cooling in spring and heating in fall. You'll hear about anything that needs repair, with the price, before any work.

What is an HVAC tune-up?

An HVAC tune-up is a yearly visit where a technician cleans, tests, and inspects your heating or cooling system while it's still working. The point is to find worn parts and small problems before they turn into a no-heat or no-cooling call.

ENERGY STAR compares it to a car tune-up: a yearly check of your heating and cooling system can improve efficiency and comfort. It won't stop every breakdown, but it gives you a clear picture of your system's condition.

What should a tune-up include?

A tune-up should follow a written checklist, not just a quick look. ENERGY STAR lists these items in a typical maintenance check-up for any system. Before you book any tune-up, ask for the checklist and compare it to this one.

Ask for the findings when the visit is done, too. A good tune-up ends with a plain answer to one question: is anything here likely to cause trouble this season?

  • Check thermostat settings so the system keeps you comfortable at home and saves energy while you're away.
  • Tighten electrical connections and measure voltage and current on motors. ENERGY STAR notes that faulty connections can make a system run unsafely and shorten the life of major parts.
  • Lubricate moving parts. Parts without lubrication cause friction in motors and use more electricity.
  • Check the condensate drain on a central AC, furnace, or heat pump. A plugged drain can cause water damage and affect indoor humidity.
  • Check the system's controls, and check that it starts, runs, and shuts off properly.

Not sure what's wrong yet?

Start with the safe checks. Many problems are a setting, a breaker, or a filter.

What's included

What a visit includes

  • A technician's check of your system
  • A plain explanation of anything we find
  • The price of any repair before work starts
  • Your decision: no repair starts until you say yes
  • Testing the system and cleanup before we leave

What you won't get

  • Repairs you haven't approved

  • Adding refrigerant without looking for a leak

What gets checked on a furnace tune-up?

For gas furnaces, ENERGY STAR says a check-up should cover gas connections, gas pressure, burner combustion, and the heat exchanger. It notes that faulty gas connections are a fire hazard, and a dirty burner or cracked heat exchanger can make the furnace run less safely and less efficiently.

A technician will usually also look at the parts that cause many winter calls: the igniter, the flame sensor, the safety switches, the blower, the filter, and on high-efficiency furnaces, the vent pipe and condensate drain.

Fall is a good time for this because the furnace may have sat unused all summer. A slow start, a weak flame, or a worn blower part is easier to deal with on a mild day than on the first cold night.

What gets checked on an AC or heat pump tune-up?

For cooling, ENERGY STAR lists three items: clean the indoor and outdoor coils, check the refrigerant level and adjust it if needed, and clean and adjust the blower for proper airflow. It says airflow problems can cut a system's efficiency by up to 15 percent, and dirty coils make the system run longer.

ENERGY STAR also notes that too much or too little refrigerant makes a system less efficient and can shorten its life. A level that's low usually points to a leak, so a good tune-up reports it instead of quietly topping it off.

A heat pump does both heating and cooling, so its tune-up covers the cooling items plus how it heats. That includes the defrost cycle, the outdoor fan, and how the thermostat brings on backup heat. Any refrigerant work is done only by certified technicians, as EPA Section 608 requires.

Ductless systems get the same kind of check. A technician will usually also clean or check the filters in each head, look at each drain line, and check that the outdoor unit has room to breathe.

When should you schedule a tune-up?

Schedule cooling check-ups in spring and heating check-ups in fall. That's ENERGY STAR's advice, because contractors get busy once summer and winter arrive. It suggests planning check-ups around the spring and fall time changes so they're easy to remember.

A heat pump works all year, so time its check-up before the season you lean on it most. In our region, that may mean before the wet, cool months, or before summer heat waves and smoke season if you rely on it for cooling.

If you have both a furnace and a central AC, you can check each one before its season, or ask whether both can be looked at on one visit. Either way, book while the weather is mild and the system isn't under strain.

What can you do yourself between tune-ups?

The biggest thing you can do is keep the filter clean. ENERGY STAR says to check it every month, change it if it looks dirty, and change it at least every three months. A dirty filter slows airflow and makes the system work harder.

A few other habits help too. None of them need tools, and none of them mean opening up the equipment.

  • Check the filter more often during heavy use and wildfire smoke season
  • Keep leaves, grass, and stored items away from the outdoor unit
  • Keep supply vents open and return grilles clear
  • Look at the condensate drain area for standing water
  • Replace thermostat batteries when the screen dims or shows a low-battery sign

Is a tune-up worth it if nothing seems wrong?

A tune-up is most useful when nothing seems wrong, because that's when small issues are cheap to catch. ENERGY STAR says maintenance helps prevent future problems and unwanted costs.

We won't tell you it prevents every breakdown. It doesn't. Parts can still wear out between visits. What a tune-up does is lower the odds of a surprise and give you time to plan if something is near the end.

And a tune-up isn't a sales visit. If a technician finds something that needs repair, we explain it and give you the price. If your system is near the end of its life, we tell you straight and show you why. The choice is yours, and nothing gets done until you say yes.

What happens on a tune-up visit?

A tune-up visit follows five steps.

  1. 1Tell us what you have. Say which systems you want checked and anything you've noticed.
  2. 2A technician checks the system. They clean, test, and inspect it and look for early signs of trouble.
  3. 3You hear what we found. We explain anything that needs attention and what it takes to fix it.
  4. 4You decide. No repair starts until you say yes.
  5. 5We test and clean up. We run the system, check that it works, and leave the space clean.

Common questions

How often does an HVAC system need a tune-up?

Once a year, before the season it works hardest. ENERGY STAR recommends annual pre-season check-ups, with cooling in spring and heating in fall.

Is a tune-up the same as a repair visit?

No. A tune-up checks and cleans a system that's working. A repair visit finds and fixes a problem. If a tune-up turns up a problem, you get the repair price and decide.

Can a tune-up lower my energy bill?

It can help. ENERGY STAR says a yearly tune-up can improve efficiency and comfort, and that airflow problems alone can cut efficiency by up to 15 percent. We can't promise a set amount of savings.

Will you try to sell me a new system during a tune-up?

No. A tune-up is for checking and cleaning. If your system is near the end of its life, we tell you straight and show you why, but there's no pitch and the choice is yours.

Does my equipment warranty require maintenance?

It might. Some equipment warranties include maintenance terms. Check your warranty papers, and keep records of each tune-up.

Is adding refrigerant part of a normal tune-up?

Checking the level is. ENERGY STAR lists checking refrigerant and adjusting if needed. A system that keeps needing refrigerant usually has a leak, and that should be found and fixed.

Not sure what's wrong yet?

Start with the safe checks. Many problems are a setting, a breaker, or a filter.
