Maintain regularly

During a tune-up, the technician will thoroughly clean all components of your AC system from the condenser and evaporator coils to the blower motor. Cleaning removes built-up debris like dirt, dust, and pollen that can impair performance and airflow. The technician will also check for refrigerant leaks, inspect the wiring, o-rings, belts, and drain lines, and ensure all connections are tight. They may lubricate parts that need it, adjust belts, and tighten loose bolts.

Another key element of a tune-up is checking refrigerant charge. Too much or too little refrigerant will reduce cooling capacity and strain your AC system. The technician can top off the refrigerant if it’s low.

A spring AC tune-up typically costs between $80 – $150 depending on the size of your home’s system and what repairs are needed. This upfront cost is well worth it to extend the life of your AC for years and keep it running at optimal efficiency. It’s much cheaper than emergency repairs if you wait until your AC breaks down mid-summer.

When to Schedule Tune-Up

Aim to schedule your air conditioner tune-up in early spring, preferably in April or May before temperatures start to rise. This gives you lead time in case any damaged components need to be replaced or there are significant issues found during the tune-up.

Trying to get last-minute AC service once it’s already hot can result in long delays as repair companies are overwhelmed with calls during peak cooling season. Early spring tune-ups also ensure that your AC is ready to keep your home cool all summer long.

2. Check Filters and Replace if Needed

Air conditioner filters play a critical role in trapping dust, pet hair, pollen, and other particles from circulating through your home. As filters collect more debris over months of use, airflow gets restricted. This causes your AC system to strain harder lowering efficiency and increasing energy costs.

Spring Air Conditioning
Ready to spring change the filters

During spring maintenance, examine your filters to see if they need replacement before summer. Check both the main filter in the air handler inside as well as any secondary filters in vent returns. The main filters should be replaced approximately every 90 days or more often if you have pets or allergies. Secondary filters can be changed less frequently.

Here are signs it’s time to swap out your AC air filters:

  • Increased cooling bills even when you’ve lowered the thermostat temperature
  • Reduced airflow from vents indicating restricted ducts
  • Visible layer of dust and debris on the filter when you hold it up to the light

Standard fiberglass filters are inexpensive, costing just a few dollars. However, upgrading to a pleated filter with a MERV rating of 13 or higher improves air quality by capturing more airborne particles. Though pricier, high-efficiency pleated filters reduce strain on your AC system since airflow isn’t obstructed.

Replacing clogged filters before summer will keep your air conditioner performing optimally all season long. Making this small investment of time and money on maintenance now will pay dividends in energy savings and preventing repairs later.

3. Clear Debris from Outdoor Unit

Your air conditioner’s outdoor condenser unit plays a key role in releasing heat from your home into the outside air. For this process to work efficiently, airflow must be able to easily pass through the condenser fins and coils. Any debris that builds up on the outdoor unit will obstruct airflow and reduce cooling capacity.

Spring Air Conditioning
Clean the outside the air conditioner unit

Take time in spring to thoroughly clean off any leaves, grass clippings, dirt or other debris that may have accumulated over the cooler months on the top and sides of the outdoor condenser. It’s best to use a garden hose set to high pressure to spray off the majority of the debris.

For caked-on dirt that doesn’t spray off, use a compressor to blow out any remaining dust between the condenser coils. You can also use a fin comb tool specifically designed to clean out AC condenser units. Avoid using a wire brush or any tool that could bend or damage the thin fins.

Proper cleaning will restore unobstructed airflow through the condenser so your AC unit doesn’t have to strain as hard this summer. The small investment of periodically washing off the outdoor unit will improve efficiency and prevent premature breakdowns.

Here are the key steps to safely clean debris from the outdoor AC condenser unit:

  1. Turn off the power to the AC system at the breaker box
  2. Hose off debris from the top and sides with high-pressure water
  3. Use a compressor or fin comb to blow out the remaining dirt
  4. Wipe down the cabinet exterior
  5. Restore power once fully dry

Keeping the condenser free of obstructions is one of the easiest DIY tasks to optimize AC performance this spring.

4. Seal Ductwork Leaks

One hidden factor that can sap your air conditioner’s cooling power and drive up electricity bills is leaky ductwork. Gaps disconnects, and kinks in your home’s ductwork system allow cooled air to escape before reaching vents. Your AC unit then cycles more frequently trying to compensate for the loss.

Spring Air Conditioning
Seal the duct tape

Take time during spring AC maintenance to inspect ductwork visually for any signs of leaks. Also, listen for any whistling sounds that can indicate gaps in duct joints or connections. Use metal HVAC tape to secure any loose sections or obvious holes. For larger gaps, apply mastic sealant to fully close the leak.

In addition to wasted energy, leaky ducts can also create humidity and condensation issues that promote mold growth. Sealing duct leaks improves efficiency, and air quality, and will save on summer cooling costs. Consider having a technician perform a full ductwork pressure test if your ducts are older or you notice your AC running consistently but certain rooms not cooling well.

Here are tips to identify and resolve the most common ductwork leakage spots:

  • Inspect under insulation for black residue indicating air escape
  • Use metal tape to secure disconnected or loose duct joints
  • Apply mastic sealant to larger gaps and holes
  • Repair kinked or crushed supply ducts restricting flow

Maintaining proper seals is essential for your cooling ducts to work effectively. Sealing any leaks now will optimize airflow and can improve your home’s energy efficiency rating by up to 20 percent.

5. Check Refrigerant Levels

The refrigerant circulating through your AC system is the essential substance that allows heat to be absorbed from your home’s air. If the refrigerant level gets too low, your air conditioner loses cooling capacity. Signs your AC refrigerant may be low including higher electricity bills and warm air coming from vents even when set to a low temperature.

As part of spring maintenance, have an HVAC technician test your refrigerant charge using gauges on the AC’s low and high-pressure lines. The technician can then top off the refrigerant if needed to restore proper levels. Any leaks should also be detected and sealed.

Keep in mind that refrigerant with the R-22 formulation is being phased out due to environmental concerns. If your AC unit is older and needs refrigerant added, a technician may recommend upgrading to a newer R-410A system for long-term sustainability. Properly recharging your AC with refrigerant each spring will keep it functioning at peak efficiency.

Here are signs refrigerant may be low and steps to maintain proper levels:

  • Higher electricity bills from AC running overtime to compensate
  • Warm air coming from vents indicating loss of cooling power
  • Have a technician test pressure levels and top off refrigerant
  • Repair any leaks detected in the refrigerant lines
  • Consider upgrading from old R-22 refrigerant systems if needed

Monitoring refrigerant levels and recharging as needed is one of the most important maintenance steps to keep your AC operating optimally.

6. Upgrade Air Filters

As covered earlier, replacing dirty air filters is crucial for proper airflow and AC efficiency. During spring preparation, also consider upgrading to a better quality air filter using thicker pleated media.

The Minimum Efficiency Reporting Value (MERV) system rates a filter’s ability to capture particles from 1-16. Standard fiberglass filters found in most homes only have a MERV rating of 1-4 and do a poor job of filtering out allergens and pollutants.

For optimal filtration and air quality, install pleated filters with a MERV rating of 13-16. The higher ratings mean they filter out tinier particulates like dust mites, mold spores, and pet dander that cheap filters miss. This keeps your AC coils and system cleaner.

While MERV 13-16 filters cost more than basic fiberglass filters, they rapidly pay for themselves through:

  • Cleaner indoor air quality leads to health benefits
  • Less strain on your AC system from particle buildup
  • Fewer repairs needed for reduced wear and tear

Here is a comparison of efficiency ratings by filter type:

Filter TypeMERV RatingFiltration Performance
Fiberglass1-4Very poor at capturing particles
Pleated13-16Excellent at removing allergens

Investing in better-quality pleated air filters is one easy way to optimize AC performance while also improving your home’s air quality. Their improved filtration protects your system from dirt buildup and reduces strain on components.

7. Weatherstrip Windows and Doors

A great DIY maintenance task to undertake before summer is checking windows and doors for any air leaks. Gaps around movable parts like sashes and frames allow cooled air to escape and hot outside air to seep in. This forces your AC unit to run overtime trying to compensate.

Spring Air Conditioning
Weatherstrip windows and doors for better protection

Weather stripping seals these cracks to prevent leaks. While especially important in older homes, it can improve efficiency in any building. Use materials like rope caulking, door sweeps, and foam tapes to seal air gaps. For windows, apply sweeps or seals between the sash and frame. Use door edge seals for any gaps between doors and jambs.

Properly weather-stripping and sealing leaks could reduce your cooling costs by up to 10% according to Energy Star. Materials cost under $10 for most DIY projects.

Here are the main steps:

  1. Inspect windows and doors for daylight gaps or hot/cold drafts
  2. Clean surfaces thoroughly where weather-stripping will be applied
  3. Apply caulk, sweeps, or foam tapes to identify leaks
  4. Make sure seals compress when windows and doors close

Take time this spring to plug any pesky air leaks allowing conditioned air to escape from your home. Combining weather stripping with the other maintenance tips will optimize your AC performance for staying cool while controlling energy costs.

8. Use a Programmable Thermostat

A final tip to maximize AC efficiency is installing an updated programmable thermostat if you don’t already have one. Models with smart technology provide greater control and convenience than old-fashioned thermostats.

Spring Air Conditioning
Use a programmable thermostat

Programmable thermostats allow you to customize temperature schedules. Set the thermostat higher when away at work, then have it automatically revert to a lower setting by the time you return home. You can also lower temperatures at night when cooling needs are less.

Smart thermostats take convenience a step further with features like:

  • Remote access to adjust the temperature from your phone
  • Voice control compatibility with digital assistants
  • Integration with home automation systems
  • Humidity and motion sensors to automatically adapt

Replacing an outdated thermostat with a smart model provides a great return on investment through summer energy savings. Units like the Nest, Ecobee, and Honeywell Home thermostats offer advanced features and are easy to program. With smart technology, convenience and efficiency go hand in hand.
