Denver Heating and Air Conditioning: Troubleshooting Tips for Your AC

You’re probably working your air conditioning system to the hilt now that warm weather is in full swing. However, as you very well know, overworking your system makes it prone to defects and inefficiencies. If you notice your AC system is less cool than usual, here’s what you need to do before you call in a Denver heating and air conditioning professional:

Replace your filters

Replacing your AC system’s filter is one of the easiest ways to ensure optimal performance. Ideally, you should replace them once every month during the warm seasons. If it’s been a while since you’ve done so, that could be the reason your AC is not hitting the desired temperatures. Check the filter model in the unit, and buy the same type.

Check for debris

After replacing the filter, go to the AC’s external unit and check for obstructions in the system. Remove any leaves or debris caught in the grate, if there are any. Trim plants that may be blocking airflow to the unit, making sure that there’s two feet of clear space around it.

Check the drain tray

Condensation occurs in an AC unit when warm air hits the cooling coil. This condensation typically drains to a tray under the unit, so if your AC has a drain tray, you need to empty it as it gets full. Some systems have a sensor switch that turns the unit off when there’s too much water in the tray.

Check the breakers

Sometimes, an AC unit will cease to function completely. Check the 240-volt circuit breaker controlling the AC unit and the 120-volt breaker controlling the furnace blower and confirm that they are in their ‘on’ positions. Reset the breakers or replace the fuse as necessary.

If none of these tips work, that’s a sign that you may have a more serious problem in your hands. In that case, it’s time to call a professional Denver heating and cooling technician. Low cool is often a symptom of coolant that needs to be recharged, and only a certified technician will be able to do this properly. Likewise, wiring problems can be easily located and fixed by such a professional.
