Benefits of a Yearly Maintenance

Yearly A/C maintenance is a very cost-effective way to improve your comfort and save some money. An HVAC system not maintaned properly will work harder and develop problems that significantly reduce comfort inside the house and increase energy consumption.
Mr Rogers recommends Preventive Maintenance Contracts that include at least two visits a year from a technician in accordance with  maintenance standards. A preventitve maintenance visit should include

• An inspection of your air conditioning equipment and unit system elements to identify any defective parts that cause the unit to don't operate safely within its specifications and features.
• A detailed report on any needed corrections and findings in the unit.
• A report of tests performed such as pressure test, temperature test, superheat and subcool test.
• The detailed breakdown of prices if any repair is neccesary
• A detailed list of work performed: items that were inspected, cleaned, repaired, or replaced.

In most cases during  preventative maintenance an ac technician can find items causing the unit to not run at its peak performance, causing a accelerated wear and overconsumption, noticing this in your electric bill.
