Air Conditioning: 5 Parts That Need Prompt Repair and Upkeep

January 23, 2018

As a responsible homeowner, it’s important to pay attention to all aspects of your living space, especially your air conditioning system. Just like your roof and gutters, it requires timely repair and maintenance to improve its efficiency, prolong its service life, and reduce the risks of breakdowns.

While every part of the unit is essential to keep it running smoothly, certain components need more care than others. Here are five of those.

5 Air Conditioning Components to Look Out For

Performing visual inspections frequently can help you determine if your air conditioning unit needs cleaning and tune-ups. Keep an eye out on these five components:

  • Evaporator and Condenser Coil. While having a clean filter will keep the evaporator coil from soiling fast, it will still amass dirt. This minimizes airflow and insulates the coil, weakening its ability to absorb heat. It’s essential to inspect this every year and clean it as needed. The outdoor condenser coils can also become mucky if the environment is dusty or if there are plants nearby. Make sure to remove debris and trim foliage back at least two feet to allow airflow.
  • Air Conditioner Filters. Clogged, dirty filters keep air from flowing freely through the system, which impairs the efficiency of your air conditioner. That said, it’s important to change them with clean ones every four to six weeks. If you have pets or if you use your unit constantly, the filters may require more attention.

You can clean and reuse some types of filters, while others need to be replaced. The filters of room air conditioners are usually located on the grill that faces into the room. For central air conditioners, their filters are typically secured somewhere along the length of the return duct.

  • Condensate Drains. This component carries the excess moisture out of your home so you don’t have to deal with a puddle of water on your floor. However, they can become clogged over time due to mold and mildew buildup. That said, have your technician clean them occasionally.
  • Coil Fins. These are a part of the condenser that helps improve heat transfer. The problem, however, is they can bend easily and block airflow through the coil. Using “fin combs” can help restore them to a near-pristine condition.
  • Window Seals for Room Air Conditioners. Excessive moisture can damage the seal, causing the cool air to leak. Your unit should be secured to your window frame to avoid energy loss.

We had the pleasure of having Brody Pennell Technician, David Mares, perform our annual Comfort Club heater inspection. David’s review found carbon monoxide levels at the heating units and vent locations. He called his field supervisor, Kyle Rudolf, and requested his presence to further assess our system. Kyle performed a thorough inspection of the heater interiors with a digital borescope and captured images of locations that showed where leakage was occurring. He recommended replacing our system due to its age and explained our options. Both David’s and Kyle’s thorough information, explanations and politeness made our choice of replacing our system an easy one.

The crew of Frank Trejo, Jesus Farias and Edwin Cabra performed our installation. They were extremely diligent about keeping our residence clean and placed protection tarps
along the entire flooring leading to the attic installation entrance. The installation is outstanding and immaculate. Also, the operation of the system was explained at the end of the job. All the crew were extremely polite, and their work was outstanding.

It was a pleasure to have Brody Pennell perform our installation with their great crew. We feel fortunate having such an outstanding company taking care of our HVAC system.

Anthony Manzo Daniel B completed an exemplary job. They arrive a little early, walked through the process and I brought them to the roof. They were very respectful of our home with appropriate covers to the floor and transit areas. The installation was spot on, the new is a little smaller and we discussed Brody Pennel minor touch. Given I painted the entire home, I thanked them and noted I complete the touch up. The new a/c is amazing - quiet, purifies the air, changes the room temperature in less than ten minutes and I suspect the energy use will be substantially less because of the attached information. Thank you for Anthony and Daniel. The best!
Response from the owner:Thank you so much for acknowledging Anthony Manzo Daniel's great work!
They were polite, professional, and knowledgeable. They showed up on time and were easy to communicate with.
Response from the owner:Thank you, Haley, for your kind words; we're glad you found our team polite and knowledgeable, and we appreciate your feedback on our communication and punctuality.
The technician (Giovanny) was terrific— very knowledgeable about our problem and our complicated heating/AC system. He finished the job quickly and.the charge was reasonable. If we have problems again, this is the company I will call. They have interesting subscription plan that ensures regular maintenance and lower costs in case of trouble. We’re giving serious thought to sign signing up for that.
Response from the owner:Thank you, Art, for your kind words about Giovanny and our services; we're glad to hear he was able to resolve your heating/AC issue quickly and that you're considering our subscription plan for added peace of mind.
