The Importance Of HVAC System Efficiency

Having the right heating and cooling system in a home or business can have a huge impact on the energy costs associated with HVAC systems. Units that are too large or too small are unable to properly heat or cool a building at maximum efficiency.

AC Preventive Maintenance Checklist: What You Can Expect

Preventive maintenance is one of the air conditioning services offered by HVAC professionals. Preventive maintenance has many benefits, including better indoor air quality and comfort, improved efficiency, and reduced risk of costly repairs.

The first thing air conditioning service technicians will do is inspect your home and air conditioning system to assess what air conditioning services your system needs. For a routine maintenance check, here is what you can expect the technician to do.

Check and Replace the Filters

Your air conditioning system filters require regular replacement to help keep out the allergens and ensure maximum efficiency. The technician will want to start with this if you haven't already recently replaced the filters.

This would be a good time to ask the air conditioning contractor about the right type and size of filters to use, how frequently to replace them, and any other such questions.

Check Refrigerant Level

You don't want your AC unit to be undercharged or overcharged. If the refrigerant levels are low, you more than likely have a leak, which the technician will resolve. On the other hand, excessive refrigerant levels, as in an overcharged unit, will only strain your compressor, which in turn may cause premature breakdowns.

Tightening Gas Connections

You want all gas connections to your system to be tight and secure to avoid any leaks. These leaks pose a safety risk, and you may end up spending a lot on electricity due to these leaks.

Cleaning Condenser and Evaporator Coils

Any buildup of dust and debris on the condenser and evaporator coils will affect the efficiency of the coils and the entire unit. The technician will clean these as part of your routine maintenance check.

Check and Clean the Condensate Drain Line

The condensate line removes the condensation produced by your air conditioning unit's evaporator coils. If it is left uncleaned or not properly cleaned, mold and algae may start to grow inside the drain line. 

These are potential allergens and may lead to musty odors and interfere with the performance of your system. Cleaning the condensate drain line clears any clogs and prevents mold and algae from growing.

Lubricating Moving Parts

Your air conditioning system includes moving parts. Without proper lubrication, these moving parts will be more susceptible to premature wear and tear. The AC expert will lubricate all moving parts to maintain and improve your system's efficiency. 

Routine maintenance checks for air conditioning systems are standard. Contact a company that provides residential AC services to learn more.
