Notice These Common AC Problems?

  • Your AC is blowing hot air: A clogged filter may be restricting airflow, or the unit may be leaking refrigerant or experiencing other parts failures. A detailed diagnostic is your first step toward a solution.
  • The AC won’t turn on: It could be as simple as a blown fuse or as troublesome as a worn-out compressor. We can do a diagnostic and provide an upfront repair estimate. If you need major repairs, we’ll walk you through your repair and replacement options.
  • Your energy bills are spiking: If your electric bills are going through the roof, an inefficient AC could be to blame. Your AC can become less efficient over time – especially without annual maintenance. As a result, it must work harder to cool the home, driving up your utility bills.
  • The AC is short-cycling: An AC that’s turning on and off repeatedly without running a cooling cycle may have electrical problems, frozen coils, a refrigerant leak, or other issues.
  • The AC is making weird noises: All ACs make some noise, but if you hear thumping, clanging, whistling, or buzzing while running the AC, you may have a faulty part, a dirty filter, or an electrical issue.

Expert Air Conditioning Repair

At Comfort Zone Service, our air conditioning repairs are designed to address issues efficiently and enhance the overall performance and longevity of your system. Our experienced technicians provide thorough diagnostics and repair options, ensuring your AC operates at its best.

Common AC issues we resolve include:

  • Clogged air filters: When air filters are clogged, airflow is restricted, which reduces your system’s efficiency. This can lead to increased energy consumption and strain the system more.
  • Refrigerant leaks: Leaks in the refrigerant lines decrease the system’s cooling performance and make it work harder to maintain the desired temperature.
  • Faulty thermostat: A malfunctioning thermostat can lead to incorrect temperature readings and inconsistent cooling. This results in discomfort and inefficient operation, as the system may run too much or too little.
  • Dirty coils: Dirty evaporator or condenser coils hinder the heat exchange process, making the system work harder. This reduces cooling efficiency, increases energy costs, and can lead to premature wear and tear on the system.

AC Repair FAQs

How often should I get my AC serviced?

Schedule professional AC maintenance once a year, ideally before summer. Regular checkups keep your system running smoothly and help prevent major issues.

How long does it take to repair an air conditioner?

The time it takes to repair an air conditioner can vary depending on the issue. Minor issues can take a couple of hours, while most major issues and extensive repairs can take up to a day.

Can I fix my AC myself?

While you can handle simple tasks like changing filters, repairs should be done by a professional. DIY fixes can sometimes make problems worse or be unsafe and void system warranties.

How can I improve the efficiency of my air conditioner?

Routine maintenance, such as cleaning or replacing filters, checking for leaks, and ensuring proper insulation, can improve your AC’s efficiency. Keeping the area around your unit clear and scheduling professional checkups also helps.

Very quick response time! I noticed the failure of my hot water heater at 7 pm one evening and had a new hot water heater installed and ready to go by 11 am the next morning. Great communication, clear recommendations, and took the time to explain details about the equipment that was ultimately installed.

Ryan H.

We have worked with Comfort Zone for about 4 years and are completely satisfied with the quality of service they provide. They recommended and installed a new AC unit, and provide us an annual furnace and AC cleaning and inspection service. We highly recommend this company for residential heating and cooling needs.
