Sometimes you need an HVAC professional for an unavoidable air conditioning repair. However, there are four simple things you can try before calling in a pro to take over:
1. Replace the Batteries in the HVAC System's Thermostat
No matter what brand or type of electronic thermostat your home's HVAC system uses, it has batteries powering it. Even if the thermostat isn't indicating the battery needs to be changed, this should always be one of the first things you do when troubleshooting a system that's not working correctly.
Just as rebooting your phone or computer often solves its random problems, replacing thermostat batteries often solves random HVAC system problems.
As the battery gets low, weird things can sometimes happen. So, before you call out a pro or troubleshoot further, simply change the thermostat batteries.
If it solves the problem, fantastic! If not, keep troubleshooting.
2. Check the HVAC System's Breaker
Your home's HVAC system has an electrical breaker dedicated to it. If the breaker tripped due to a power fluctuation or other momentary issue, then it will not allow the air conditioner to draw power.
Find the HVAC breaker in the main electrical panel and determine if it has been tripped. If so, resetting the breaker will solve the problem. If it isn't tripped or doesn't solve the problem, then keep troubleshooting.
3. Change the HVAC System's Filter
Many residential HVAC system problems can be solved by changing their filter. As furnace filters clog with dust, hair, and grime, it blocks airflow into the system. Even a small restriction in the airflow can greatly affect overall system performance.
Changing the filter is inexpensive and simple to do. However, it is vital to note you must use the right size filter and should avoid overly restrictive HEPA filters unless they are approved by the manufacturer of the HVAC system.
4. Melt Built-Up Ice Formation
When it is very humid or excessively hot, condensation can become trapped around the evaporator coils in an HVAC system and freeze. The resulting ice buildup prevents the air conditioner from working correctly.
If ice has formed, then simply turning off the HVAC system for an hour or so will melt it. Once melted, your air conditioner will work as designed.
However, if the system continues to freeze up, or none of the other suggestions have solved the current problem, then it is time to call a pro.
