When your air conditioning system fails, Murphy’s Law states that it will be on the hottest day of the year. Before you call us, here are a few troubleshooting tips that might get you back up and running. While there are problems only a professional can fix, it may just be a simple problem that’s causing the malfunction, particularly if your system is relatively new and has not had any issues in the past.
1. Set your thermostat to the lowest possible temperature then set it well above the current room temperature. Listen for the system to turn off. If it does not, there are two possibilities — the breakers or fuses have blown, or the thermostat may be malfunctioning.
2. Check the breakers or fuses for the air conditioning unit. For a breaker box, open the panel up and check to see if any of the breakers have tripped to the “off” position. Move these back to the “on” position, and have someone else turn the temperature to below room temperature. If the breaker throws again while you’re standing there, there may be an electrical issue with the air conditioner. If you have fuses, these will typically be located in a fuse box outside, next to the unit. Turn the fuse switch to the off position, then examine the fuses. If any appear burnt, or if they make a noise when you shake them, replace the fuses. Turn the switch back to the on position and then turn the thermostat to a temperature below room temperature.
3. Check the air flow to the system. Blocked air flow is a common reason why air conditioners suddenly quit working. Go outside and check around the unit. If there are weeds or grass around it, trim these away and try the unit again. If the filter in the inside unit has not been changed in a while, take it out of the unit, then turn the system back on. Don’t forget to replace the filter with another – pleated are best.
4. Examine the unit for any visible signs of problems. If all of the above steps have failed and your unit still will not function, look for issues such as ice build-up inside the indoor unit, water leaking from the unit, or oil that has spilled from the outside unit’s casing. These are signs that you will need to contact us.
While a general HVAC company can typically solve any issues you’re experiencing, if your system is still under warranty, you definitely want to pick the right company so that you don’t void your warranty.
Check with online review services, such as Angie’s List, to get an idea of the ratings for the residential HVAC companies in your area. You can also check with the Better Business Bureau, or ask your friends in the neighborhood who they have worked with in the past. In larger areas, you can also use Google maps or places app to get reviews of local companies. These can be very useful in narrowing your search.
Keep in mind that on severely hot days or stretches where the weather is very hot, you may not be able to get a service tech out to your location immediately. If you or someone in the home has health issues that could be worsened by high temperatures, let the residential HVAC company know — they’ll make an extra effort to get you taken care of.
