AC Installation & Replacement in St. Johns

Our HVAC installation teams can install central air conditioning systems, ductless mini-splits, swamp coolers, and single-room window units. We will calculate your unit's appropriate size and help you select the ideal system for your comfort. 

Of course, even the best-built air conditioner won't last forever. When your old system has stopped delivering the cool comfort you desire, we will help you identify the best replacement option. We will remove the old unit and dispose of it, so all you have to do is sit back and relax as your new system cools your home. The benefits of a new AC system can include:

  • Reduced energy consumption
  • Lower utility costs
  • Quieter operation
  • Improved comfort and air quality

AC Tune-Ups & Maintenance in St. Johns

Regular AC tune-ups help ensure your system will deliver the comfort you desire. An annual tune-up helps optimize the performance of your air conditioner. This has the added benefit of reducing wear and tear on your system. In turn, this extends the life span of your system and reduces your long-term repair and replacement costs. 

Our AC tune-ups include the following and more:

  • Check refrigerant pressure
  • Leak inspection
  • Clean condenser coil
  • Check fan motor and pressure amperage
  • Test safety switches
  • Test defrost controls
  • Inspect and tighten electrical connections
  • Inspect blower wheel
  • Test and calibrate the thermostat

Similarly, scheduling regular maintenance is something you don't want to skip. In fact, many warranties require proof that the unit is properly maintained by a licensed and certified HVAC professional. Our team of specialists has a thorough understanding of air conditioners and their maintenance requirements. We perform a thorough inspection of each unit and ensure that the unit is primed for optimal performance. From checking for leaks to testing for tightness, we inspect every bolt, nut, coil, fan blade, and more.

Contact David Gray Heating & Air at (904) 605-8190 to schedule AC tune-ups or maintenance. It's our pleasure to schedule an appointment that fits comfortably within your schedule.
