Why Preventative Maintenance Matters

Don’t overlook your air conditioning system when making plans for home maintenance. Your air conditioning system is a among the biggest investments in your home, and preventative maintenance is the best way for your to maximize the value of that investment. Underestimating the importance of air conditioning system maintenance can be a costly mistake.

Without AC maintenance, you may experience:

  • Excessive strain on the system
  • More frequent repair issues
  • Shorter equipment life
  • Higher home cooling costs
  • Poor indoor air quality

Neglecting maintenance can have another serious consequence related to your equipment warranty. Virtually all manufacturers require annual maintenance to keep the warranty in effect and may not cover repairs or replacement of a system that has not been maintained. Our AC maintenance in Orange County fulfills the requirements of manufacturer warranties and ensures that your system continues to provide reliable and energy efficient home cooling, year after year.

Professional Orange County AC Maintenance

A well-maintained AC unit operates more reliably, and efficiency, breaks down less frequently, and may last longer. We provide Orange County AC maintenance to help optimize cooling capacity, ensure reliable performance, increase energy efficiency, and improve your home’s indoor air quality.

When performing routine maintenance, our HVAC technicians will:

  • Carefully inspect all AC system components
  • Clean condenser coils

  • Inspect the blower motor
  • Look for signs of wear and tear
  • Check the thermostat

During your maintenance visit, our technicians will make minor adjustments and small repairs to optimize efficiency. For larger problems, we may recommend a repair to make sure the air conditioning is ready for summer. Fixing issues as they arise is the best way to avoid air conditioning system failure in the middle of a heatwave.

Frequently Asked Questions
  • Should I replace or repair my AC unit?
    A:

    Many customers ask if they should repair a broken air conditioning unit versus a full replacement. Often, a well-maintained and newer AC unit will be able to be repaired depending on the issue. If it is a part under warranty, replacement of the part is a simple fix. However, if the AC is more than 10 years old, has not been regularly serviced, or is in need of a major repair, replacement is the best option. Our team will provide all available options for homeowners to consider.

  • What's a Pre-Installation Evaluation? Does My New A/C Need One?
    A:

    In short, yes. A first step is conducting an energy audit to determine the energy load for your home. Calculating the load tells the experts at John Stevenson Plumbing, Heating & Air how much heat your house gains throughout the day & what size air conditioner will work best to keep it cool. This is critical as most A/C installation issues stem from an improperly-sized air conditioning unit.

  • Is Your Home's Ductwork & Design Able to Handle a New A/C System?
    A:

    Often your old, existing ducts can’t handle the airflow of a newly installed air conditioner. Any upgrades to accommodate a new system will likely increase the cost to install an A/C unit, but will ultimately help you avoid costly, high energy bills & hot rooms in the future.

  • What Type of Central A/C Unit Should I Install?
    A:

    Here’s where the load calculation comes into play, as you want to pick the right size A/C unit to install – either too big or too small of an A/C unit can lead to costly repair or replacement down the road. Call the HVAC professionals at John Stevenson Plumbing, Heating & Air, they’ll know which A/C unit is perfect to install in your home at the lowest price.
