With years of experience and a team of highly skilled technicians, we are committed to ensuring that your AC system operates at peak performance, keeping you comfortable throughout the hot summer months.

Comprehensive AC Repair Solutions

At Mannix Heating and Cooling, we understand the importance of a properly functioning air conditioning system. Our technicians are trained to diagnose and repair a wide range of AC issues, including:

  • Refrigerant leaks: Low refrigerant levels can cause your AC system to work harder, leading to reduced efficiency and potential damage to the compressor.
  • Faulty thermostats: A malfunctioning thermostat can cause your AC system to cycle on and off frequently or fail to maintain the desired temperature.
  • Clogged air filters: Dirty air filters restrict airflow, causing your AC system to work harder and potentially leading to freezing of the evaporator coil.
  • Electrical issues: Loose connections, blown fuses, or tripped circuit breakers can prevent your AC system from functioning properly.

Our technicians use state-of-the-art diagnostic tools and their extensive knowledge to quickly identify the root cause of the problem and implement effective solutions. We prioritize timely and efficient repairs to minimize any disruption to your daily life and ensure your comfort.

Proactive Maintenance for Optimal Performance

Regular maintenance is essential to keep your air conditioning system running smoothly and efficiently. Mannix Heating and Cooling offers comprehensive maintenance plans designed to prevent breakdowns, extend the lifespan of your equipment, and optimize energy efficiency. During a maintenance visit, our technicians will:

  1. Inspect and clean the condenser and evaporator coils: Removing dirt and debris from the coils improves heat transfer and ensures optimal system performance.
  2. Check and calibrate the thermostat: Accurate temperature control is crucial for maintaining a comfortable indoor environment and minimizing energy waste.
  3. Lubricate moving parts: Proper lubrication reduces friction and wear, extending the life of your AC system’s components.
  4. Test electrical connections and components: Identifying and addressing electrical issues early on prevents more serious problems from developing.

By investing in regular maintenance, you can enjoy the peace of mind that comes with knowing your AC system is in good hands. Plus, well-maintained systems typically have lower operating costs and a reduced risk of unexpected breakdowns.

Eric Holzworth stopped by my house the next day to go over my options. He...

We were in desperate need of a fix on our AC system during the July heatwave. The issue arose on a Saturday. Mannix came to the rescue in short order, fixed it, and at a reasonable price. Silvio G was the technician, and he was GREAT. We would definitely use Mannix again!

I’ve been using Mannix for years and have never been disappointed. They’ve replaced my HVAC, hot water heater and installed a humidifier on my furnace. Whenever I need them, they can get me on the schedule in a timely manner. All the personnel are great and I trust Jerry and his team...

Been a happy Mannix customer for a few years now, but recently had them replace our aging HVAC system.
