AC maintenance FAQ

Why is seasonal AC service necessary?

Air conditioners have many different parts that require regular maintenance to run efficiently during the service life of the equipment. Depending on the brand, you may be required to get a yearly AC tune-up to comply with the manufacturer's warranty program.

How often do air conditioners need maintenance?

Ideally your air conditioner housing, coils, vents, fins and ducts get cleaned once at the beginning and again at the end of the season.

Pre-season tune-ups

Most people get their AC tuned up once a year in the spring so it's ready to go when summer arrives.

End-of-season tune-ups

It’s also a good idea to do some end-of-season maintenance on your outdoor AC unit. Also known as ‘winterizing,’ the basic maintenance done in autumn helps keep your air conditioner in better shape for longer.

End-of-season AC unit tips:

air conditioning preventive maintenance Milwaukee WI

A little prevention goes a long way toward extending the service life of your AC.

  • Remove any debris on or around your AC (grass clippings, weeds, leaves, bugs, dirt, etc)
  • Clean or replace the filter
  • Inspect and clean the evaporator coils
  • Examine the coil fins for damage
  • Test for any refrigerant leaks that may have developed over the summer (better taken care of sooner than later)
  • Inspect electronic connections; tighten or repair if needed
  • Clean and lubricate the motor unit if needed

It’s also a good idea to cover your outdoor AC unit before winter arrives. Outdoor units are designed to withstand severe weather, but it never hurts to provide added protection. If water gets on the condenser coils and freezes it can cause damage.

Whether or not you choose to cover your air conditioner, it’s best to clear snow and ice buildup from on top, and monitor for rodent hibernation.

What does an AC tune up include?

A technician will thoroughly inspect and evaluate your air conditioner and cooling system.

During your AC tune-up we’ll:

  • Assess the overall condition
  • Check refrigerant levels & pressure
  • Look for any leaks
  • Examine all electrical parts & connections
  • Tighten or lubricate mechanical parts if necessary
  • Observe operation of blower motor & belt
  • Clean blower components if needed
  • Measure airflow
  • Measure air temperature at supply & return
  • Check oil & air filters
  • Test startup function
  • Examine & clean condenser/evaporator coils

Don’t wait for a heatwave to test your air conditioner – call Prompt Heating & Air Conditioning to book preventive maintenance and stay cool all summer long.

How long does an A/C tune up take?

It depends on the state of your air conditioner and what we find during the inspection, but generally around an hour. If repairs, replacement parts or refilling refrigerant is needed it could take longer.

What happens if you skip AC maintenance?

air conditioner maintenance service Milwaukee WI

We service air conditioners for single-family homes, rental properties & small businesses.

Skipping the yearly tune-up means a steady decline in performance and a steady rise in energy consumption.

More dust and dirt builds up in the filters, which means the air conditioner has to work harder to cool your home. So you'll probably have higher energy bills, it can get noisier, and parts can wear out faster.

Skipping the annual tune-up also gives minor issues a chance to become bigger, more expensive problems to fix later. Over time, if AC maintenance is neglected, the unit will have a shorter lifespan.

Can I use a pressure washer on my air conditioner?

This is a bad idea. Power washers spray much harder than a garden hose spray setting and can damage the coil.

Should outdoor AC units be kept in the shade?

Outdoor central air conditioners are built to operate in extreme weather, so there’s no need for shade. In fact, plants and shrubs too close to your AC unit can restrict airflow, making things worse. If you’re planning yard work or landscaping updates, it’s a better idea to increase the amount of shade on your home itself. This will help keep it cooler indoors so your AC doesn’t have to work as hard.

How do I know if my evaporator coil is dirty?

The main sign is poor airflow. If your system is blowing cold but not blowing strong enough, it could be a dirty evaporator coil reducing air pressure.

Can I move my outdoor air conditioner myself?

It’s better to call a professional for help. Reason being, relocating an outdoor AC unit involves pumping out refrigerant from the system before moving it, and reconnect the lines/refill refrigerant once it’s in the new position. EPA regulations require a certified technician to handle refrigerant.

A qualified HVAC contractor will also consider things like:

  • Making sure the unit isn’t on an incline that works against refrigerant circulation
  • Taking care the refrigerant lines do not have severe angles (which leads to leaks)
  • Lines may need to be replaced or extended depending on how far you need it moved

If you need help relocating one or multiple outdoor air conditioners, give us a call and we’ll make sure it gets done correctly the first time.
