Air Conditioning

There are lots of critical parts responsible for keeping your A/C unit in proper working condition. If any of them malfunction or break down, the entire system is likely to fail! If you’re experiencing any of the following problems with your cooling, call us 24/7 for all emergency situations:

  1. Turning on but doesn’t blow cool air into your home
  2. Doesn’t turn on, despite proper thermostat readings
  3. Cycles quickly and for just a few minutes at a time
  4. Lights flicker or breakers trip when kicks on
  5. Strange noises or smells accompany the on function

All these problems and more signal the need for a technician to call on you. Rest assured, we’ll get to the bottom of the issue and restore integrity to your home’s air conditioning. Our process is simple and thorough, ensuring we don’t miss anything. Our multi-point system check includes, but is not limited to, the following:

  1. Visual inspection of the unit, connections and thermostat
  2. Air conditioning diagnostics, which involves running the cooling (if possible)
  3. Manual inspection of moving parts, filters and connections
  4. Part-specific testing and troubleshooting
  5. Diagnosis of the problem and a scope of work to correct it

Through our evaluative approach, we solve problems quickly and promptly. We don’t leave until there’s cool air blowing throughout your home once again. We stand behind our work as well. So in the rare event of a replacement part failing or the initial failure was misdiagnosed, we’ll make it right.

HVAC Maintenance

To prevent breakdowns, inefficiencies and other problems with your air conditioner nothing beats routine maintenance and tune-ups. JMB A/C & Heating offers complete heating and air conditioning maintenance services, designed to ensure the operational reliability and efficiency of your cooler and heater. Acting proactively keeps you from running into a variety of unnecessary headaches, including:

  1. Breakdowns that leave you without cool air during high-temp summer days
  2. Major malfunctions that affect your entire unit, costing more to resolve
  3. There are strange smells or noises when the heat kicks on
  4. Premature failure of your air conditioner and the expense that comes with a brand-new one
  5. Your heater cycles rapidly or not often enough

A/C tune-ups and bi-annual maintenance cost very little, especially in comparison to repairs, and take almost no time. Schedule yours before and after peak cooling season to make sure your air conditioner gets the care and attention it needs! Tune-ups will help extend the cooling system’s life, improve efficiency, prevent breakdowns, and minimize problems.
