Ask Dirk: What happens during my HVAC maintenance service?
Your HVAC system is a mechanical system with lots of moving parts. Without regular maintenance and care, its performance will start to decline and eventually the entire system will just plain fail. A heating and cooling system replacement costs thousands of dollars, so regular maintenance can extend its lifespan and protect your wallet.
What does the technician do?
Inspect and Change Your Filters
We’ve talked about how important clean filters are regularly in this column, and we’ll probably keep talking about it – it’s that important. In our dusty climate, filters need frequent changing because they trap all kinds of dust, debris, germs. Dirty filters can cause inefficient heating or cooling, and poor indoor air quality.
Visual Inspection of the Entire System
A thorough visual inspection can identify problems before they happen, and it’s a good idea to get it done before peak cooling or heating season begins. Addressing minor problems found during regular maintenance service can greatly reduce potential emergencies.
Clean and Remove Debris
While filters help with dust and debris, particulates also collect on blowers, moving parts, condensing units, and other system components, interfering with smooth operations and potentially causing corrosive damage to internal systems.
Check the Condensate Drain
A clogged condensate drain in your air conditioner and heat pump can obstruct water flow, causing moisture to accumulate in the system. This can potentially lead to mold, water damage, uneven temperature regulation, bacteria, and compromised air quality.
Check the Electrical Connections and Voltage
HVAC connections and systems can come loose or break over time. Frayed and damaged wires should be replaced to minimize the risk of fire and component failure.
Inspect Exhaust Outlets
Gases like carbon monoxide escape through exhaust outlets. Clogs can lead to dangerous build-up, and possibly compromise your safety. Your technician will check for signs of corrosion, leaks, and backdraft in the system, chimney flue and vent stack.
Check Fuel Lines and Connections
Leaking gas and fuel lines in your system can be a fire hazard, and disconnected fuel lines, accumulated soot in the burners and cracked heat exchangers can impact on the system’s efficiency.
Check the Refrigerant Levels
If your air conditioner doesn’t have enough refrigerant in it to cool the air efficiently the compressor will have to work harder to achieve the desired level of temperature, which can damage the system. Losing refrigerant often means leaks, which need to be detected and repaired.
A final note
Regularly servicing your HVAC system is beneficial in many ways, with improved reliability, lower energy bills, longer equipment life, and a safer, healthier environment. Additionally, a thorough examination by a trained technician will help to ensure the whole system is healthy, and if it’s not, your technician will advise you of any needed repairs.
With summer rapidly approaching, it may be a good idea to get your system serviced early to make sure you’re covered before it gets too hot, so you have ample time to enjoy your air conditioner.
