Premise:

Preventative maintenance of residential air conditioning units is known to restore performance capacity, improve comfort and lower energy costs.

Summary of Study:

• Restore capacity by 1/2 to 3/4 tons
• Improve humidity control
• Reduce running time

All of these lower energy costs

Good maintenance programs with residential air conditioning is profitable for the homeowner. These demonstrations showed an average savings of $32.76 / month based on $.08/kwh. Run time was reduced by an average of 1.70 hours per day. Even though it was not included in the scope of this study preventative maintenance extends the life of air conditioning equipment.

In conclusion, air conditioning maintenance benefits the consumer by lowering his operating costs, increasing his comfort control capacity and extending the life of the equipment.

Recommendation:

Data collected and observations made during this series of demonstrations implies strongly the need for preventative maintenance. The economic payback will be highly beneficial to the consumer.
