5 Common Air Conditioner Issues in Winter

Autumn leaves are now appearing and winter is quickly approaching.

Homes, offices and retail spaces all benefit from air conditioning all year round and research has proven that productivity improves with quality air conditioned spaces. Workers perform better and customers feel better as we all like to be cool in the summer and warm in the winter.

If the worst should happen and you need assistance with your AC unit, RCL are available and offer a comprehensive 24 hour call out service. We come out and instruct our clients how to use your system and ensure the air-conditioning is balanced and working at optimal output.

Some common issues for you to look out for and hopefully prevent throughout the winter include:

1. OBSTRUCTION

Always keep your units free from obstruction to ensure your system doesn’t have to work any harder than necessary. This is important for both outdoor and indoor units.

Make sure nothing is blocking the indoor vents or air discharge points to enable your systems to run as efficiently as possible.

2. THERMOSTAT

Set your thermostat controls to a reasonable level (even when you first turn on your system!). 23ºC is a reasonable temperature for homes and offices. A temperature of 30ºC for example is excessive and strains units unnecessarily.

When temperatures are cold, it’s important to position the louvers on the indoor units vertically (or as vertically as is possible) to force the heat down into the room and achieve maximum efficiency from your unit.

If a fault code does appear, the common solution of switching it off and back on is often the answer. Be sure to leave the system off for 10 seconds before restarting. The manual reset is the first thing any engineer will try when called out so save yourself some money by trying it yourself first.

3. FALSE ALARMS

When running in heating mode, air conditioning units stop producing heat from time to time. This allows the system to enter defrost mode, which is necessary to prevent ice and frost building up in the condenser coil. If you are not sure what is happening, wait to see if they start producing heat again before calling someone out.

4. SENSORS

Room air conditioner units feature a thermostat sensor. It’s located behind the control panel and measures the temperature of air coming into the evaporative coil. If the sensor is knocked out of position, the air conditioner could cycle constantly or behave erratically. The sensor should be near the coil but not touching it; adjust its position by carefully bending the wire that holds it in place.

5. DIRTY FILTERS 

If you’re using your air conditioning unit a lot during the winter months you’ll tend to find your filter gets a lot dirtier. This build up of dirt can cause a restriction in the air flow causing a knock on effect that makes the furnace have to work twice as hclean_and_dirty_ac_filter_magnificent_airard to maintain the right temperature. Simply check your filters at the very least once a month and replace them when necessary.

 

 

EXTRA TIP: LEAKING

People often see water leaking from their outdoor condensers and assume that something is wrong. However, often when the condensers are surrounded by melting snow and ice, it’s completely normal for that to happen when in heating mode.ac-leaking-water

CAUTION: Is there a public walkway or footpath beneath the condensers? The leaking water can turn into a slipping hazard if it freezes. Divert the water and allow it to drain into a safe area.
