RS Andrews: Atlanta's HVAC Maintenance Experts

Every HVAC system needs regular maintenance to ensure that it performs efficiently, and that the system enjoys a long life. At RS Andrews, we help people all over Atlanta maintain their HVAC systems every single day. If you need HVAC maintenance call us today, and we will take some of the mystery out of your HVAC system, and make sure it runs efficiently for many years to come.

The expert HVAC technician we send to your house will help you decide on what HVAC preventative maintenance you require, which may include changing your air filter regularly, tuning up your HVAC machinery on an annual basis, or ensuring that your HVAC unit has a proper refrigerant charge. HVAC maintenance costs do not have to be high, if they are done properly, and ultimately HVAC maintenance from RS Andrews saves you money by decreasing your energy bills and by extending the life of your HVAC system.

Most people neglect the proper changing of their heating, ventilation, and air conditioning air filter. In truth, these air filters should be changed, or at least cleaned, one time every month during peak season use in order to maintain maximum efficiency and performance of the heating, ventilation, and air conditioning system unit. In off peak seasons like fall and spring, you might get away with changing or cleaning the filter only once every three months.

An annual HVAC equipment tune up is another important element in HVAC maintenance procedures and RS Andrews offers the most thorough, comprehensive HVAC tune up in Atlanta. Typical items to go through on the annual equipment tune up include tightening up the various electrical connections, as well as measuring current and voltage on the motors, which is important as poor electrical connections when present will create potentially dangerous system operation or at the least, the life expectancy of the major parts will be lessened, if this is not properly done; oiling all the important moving parts, which is necessary to prevent excess friction which causes premature wear and tear; investigating the condensation drain on your unit, since a drain that is blocked up might lead to water damage inside the house, and will at least impact the humidity level inside; and inspecting the system controls to make sure that they are working correctly and safely, to ensure that the start up cycle equipment is starting up, running, and turning off properly.

Making sure that your HVAC unit has proper levels of refrigerant charge is another critical component of our HVAC Maintenance program. Such a well charged unit will run more efficiently and last longer. In order to ensure that your Heating, Ventilation, and Air Conditioning unit has the proper refrigerant charge levels present, your RS Andrews HVAC expert technician will test and verify that the unit is correctly charged to the optimum level.

The bottom line is that regular service on your HVAC system by an RS Andrews HVAC technician will save you time, money, and hassles, and will keep your HVAC system running reliably for a long, long time.
