Houston Preventive Maintenance Contracts

Major HVAC equipment manufacturers design products that will provide exceptional comfort and efficiency through countless heating and cooling seasons. While modern furnaces and air conditioners are very reliable, stress and wear on moving parts accumulates over time. Regular preventive maintenance is a service that maximizes system efficiency while reducing the chance of an unexpected equipment breakdown.

At P & M Air Conditioning and Heating, we offer seasonal maintenance plans developed to identify potential problems before they can negatively impact the performance of your equipment.

Our Maintenance Services

Routine HVAC maintenance will help ensure that your air conditioning and heating system will consistently conform to the manufacturer’s performance guidelines.

Our maintenance programs were developed to address the critical issues that commonly affect central heating and air conditioning systems.

Benefits of Preventative Maintenance

Routine maintenance provides many benefits when the work is performed by a licensed, professional contractor like P&M Air Conditioning and Heating. Some of the benefits include:

  • Improved Comfort: Minor performance problems often remain hidden as they degrade indoor comfort and raise annual utility costs. Our mechanics have serviced and repaired every major brand of equipment, and they have an advanced knowledge of the refrigeration cycle. We can maximize the performance of your system so that your home stays comfortable with less equipment cycling.
  • Reduced Repair Costs: Our maintenance plan customers receive a 15 percent discount on all service calls and they receive priority service.
  • Energy Savings: When we service your equipment, the system is calibrated back to the manufacturer’s original specifications. If an air conditioner is compromised, it will need to cycle more frequently in order to meet the indoor load requirement. This will raise utility costs and further stress other components in the unit.
  • Longer Equipment Life: When a HVAC system is properly maintained, it accumulates fewer runtime hours. Internal parts that are obstructed, clogged or dirty must work longer and harder to meet the thermostat call. Seasonal maintenance reduces stress on vital components, which will substantially enhance the lifecycle of your equipment.
