The Three Most Common “End of Summer” Air Conditioning Service Calls

This entry was posted in Blog on by .

As they say in Arizona, there’s hot news and there’s bad news. The hot news is summer is starting to wind down, and temperatures are slowly dropping into the 90s. Fall weather, cooler nights and moderate temperatures are not far off. The bad news is, your air conditioner has been working overtime, and even though we are close to the end of the season, many air conditioners may require service due to the extreme running conditions over the last four months.

Your Air Conditioner Deserves a Break

By mid-September, your air conditioner has been running full blast since late spring. This puts a strain on all the parts of your AC system. Throw in a few major monsoon thunderstorms, which bring driving rains, high winds, lightning and power outages, and you have plenty of opportunities for electrical issues and worn-out components in your AC unit.

Here’s a list of some of the more common end-of-summer repairs we see this time of year:

  • Blown Capacitors, Faulty Contactors

    Electrical repairs are very common at the end of summer. The intense heat, fluctuating power grid, and extreme wear and tear take a toll on electrical parts, such as capacitors and contactors. Capacitors are one of the most common replacement items on AC units. Not surprisingly, we see an increase in electrical problems after big storms.

  • Refrigerant Leaks

    Refrigerant is a key element in cooling. Forced through pressurized lines as it transfers heat from inside your home to the outside, the refrigerant is contained in a closed system. After four or five years of service, pressurized lines can develop tiny pinholes due to rust or corrosion, allowing small amounts of refrigerant to escape. Once refrigerant starts leaking, it will never stop. Professional hvac service is required to fix this vexing problem.

  • Dirty Air Filters, Clogged Condenser Coils

    One of the most important aspects of effective air conditioning is the free flow of air throughout your entire system. Air from your home is constantly being circulated through your air conditioner and whether it’s air filters or condenser coils, these components need to be cleaned or replaced regularly. Dirt, grime, pet hair and dander, dust and other particulates will accumulate on air filters or coils and negatively impact the cooling process. Air filters should be changed at least six times per year and condenser coils should be cleaned as part of your spring and fall service calls.

When Summer Turns to Fall, Remember to Give Us a Call

We recommend two service calls per year, in spring and fall, to keep your HVAC unit running smoothly. Scheduling a fall service ensures your air conditioner will be checked for any problems that may have occurred during heavy summer use, and we will also inspect your furnace to make sure you are ready for the change of seasons. If your air conditioner is giving you headaches, give a call to Chandler Air, Inc.
