Neighbors A/C Do-It-Yourself Tips

The following Do-It-Yourself tips are simple measures that will safeguard the life of your unit, reduce energy costs, and improve overall system efficiency.


You should replace your air filter every two months. However, it is important to check your filter every month especially if you have pets or allergies. A dirty filter can restrict your AC’s airflow requiring it to work harder than necessary, cause your evaporator coil to freeze up and send dust and other pollutants right back into your air! If you have a washable filter, make sure it’s completely dry before you place it back inside your unit to avoid any mold growth.

Neighbors A/C can custom make any size filter to meet your comfort needs. We also have standard sized filters. Give us a call, we will be happy to assist you!


There are two ways that you can confirm your filter size without us coming out to your home, all you need is a tape measure. If you currently have a filter in your unit, take it out and measure the dimensions of your filter. If you don’t have a filter to measure, slide the tape measure into the filter cavity until it hits the back of the cavity, this is your filter length. Then measure how wide the opening is to get your filter width. It’s as easy as that!


Your condensing unit emits the hot air extracted from inside your home. Having debris (leaves, branches, grass clippings, etc.) stuck in the condensing coils acts as a blockade that will cause your unit to work harder to expel the hot air.

You can clean your condensing unit by using a brush, broom or a vacuum cleaner with a soft brush attachment to clean the surface. A quick wash with the garden hose works too!


Periodically check the base pan under the inside air handler and remove any dirt and mildew that have accumulated. You may need a wet vacuum to do this. You should also connect the vacuum to the outside drain line to clear out the natural build-up of grime.

Making sure your base pan and drain line are clean will help your unit drain properly and increase system efficiency. It will also prevent unnecessary and costly service calls to your HVAC contractor.


You can clean your garbage disposal by grinding up ice cubes and salt to remove tough residue that has built up inside the disposal. You can also grind citrus fruits (e.g., oranges, limes, grapefruit, lemons, etc.) to get rid of foul odors and freshen things up!


You can avoid moisture and mildew buildup by:

  • Use a dehumidifier to dry the air and walls and keep extra moisture out
  • Don’t hang damp clothes in closets
  • Periodically air-out your bathroom and kitchen sink cabinets
  • Install vents with ventilating fans in your kitchen and bathrooms
  • Choose shower curtains that dry and clean easily to avoid soap residue
  • Keep your showers and tubs clean of soap-scum so that they dry quickly


Clean your humidifier at the beginning of every heating season. To ensure cleaning is done properly, review your owner’s manual for instructions on how to clean the evaporator pad and external components. Or, you can call the experts at Neighbors A/C and we will be happy to help!


Check the seals around windows and doors to ensure that air is not escaping. Faulty seals or weather strips can decrease the efficiency of your AC and have you paying more money a month than you should! Seal these areas using a high quality caulk or add weather strips around moving parts of windows and doors to prevent air loss.


If you have a mechanical thermostat, making the simple upgrade to a digital thermostat will help maximize your AC unit’s efficiency. Not only will you save money on your monthly utility bills, but digital thermostats are more accurate and easy to program. Be sure to preset your desired temperatures for specific times of the day to fulfill your comfort needs.


Maintaining your dryer can help prevent house fires, reduce energy costs, and preserve the quality of your clothes. We recommend you clean your lint filter after every dryer load and have your dryer vent checked annually by a professional. Be sure that the outside vent flaps open properly and are not blocked by dirt and debris.

The following signs are indications that your dryer vent is blocked and requires cleaning:

  • Heavy clothing, such as towels and jeans, take longer than usual to dry.
  • The laundry room feels overly humid and clothing feels hotter than usual at the end of a cycle.
  • There is a burning smell when using the dryer.
  • The outside vent hood flaps do not open properly
