  • Why is my air conditioner blowing warm air but the fan is running?

    Most often, this is caused by a clogged air filter or a tripped circuit breaker to your outdoor unit. Check your thermostat to ensure it’s set to "Cool" and not just "Fan On." If those aren't the culprits, you may have a refrigerant leak or a frozen evaporator coil, which requires a professional diagnostic.

  • Why is my AC unit making a loud banging noise?

    Banging usually points to a loose or broken mechanical part, like a connecting rod or piston pin inside the compressor. It can also be caused by debris (like a stick) caught in the outdoor fan. We recommend shutting down the system immediately to prevent further expensive damage to the motor or compressor.

  • How do I fix an AC unit that is leaking water inside?

    The most common cause is a clogged condensate drain line. Over time, algae and debris can block the pipe, forcing water to back up into your home. You can try using a wet/dry vac on the outdoor drain line to clear the clog, but if the leak persists, your drain pan may be cracked or your evaporator coil may be frozen.

  • How much does a standard AC repair cost in Coalinga?

    While every repair is unique, a standard diagnostic visit in Coalinga typically ranges from $180-$850. Minor repairs like a capacitor replacement or drain line flush are generally between $100-$350, while major component failures will require a custom quote. We always provide upfront pricing before any work begins. We also employ a Flat-Rate Pricing Model and do NOT charge you the typical $100-$200 Hourly Rate.

  • What is the '$5000 rule' for deciding to repair vs. replace a furnace?

    The $5000 rule is a simple formula: multiply the age of your unit by the quoted repair cost. If the total is more than $5,000, it’s usually more cost-effective to replace the unit. For example, a 12-year-old furnace needing a $500 repair ($6,000 total) is likely a candidate for replacement.

  • Can a smart thermostat really lower my monthly energy bills?

    Yes, homeowners typically save about 8% to 12% on heating and cooling costs by switching to a smart thermostat like Nest or Ecobee. These devices learn your schedule and automatically adjust temperatures when you're away or asleep, ensuring you never pay to cool an empty house.

  • How do I improve indoor air quality for someone with allergies?

    Start by upgrading to a high-MERV pleated filter (MERV 11 or 13) and scheduling a professional duct cleaning. For long-term relief, consider installing a Whole-Home Air Purifier or UV germicidal lights inside your HVAC system, which neutralize mold, bacteria, and allergens before they circulate through your home.
