With the number of do-it-yourself video tutorials and articles available online that pertain to heating, ventilation, and air conditioning repair, it might be tempting to resolve some issues yourself to save money. While there are certainly minor problems you can fix on your own, there are also emergencies that still require the skills and experience of a licensed HVAC contractor. Listed below are some of them.

3 Issues When You Must Call an HVAC Contractor 

1. Clogged Lines

Your air conditioner is equipped with a drain line that leads water formed by condensation away from the evaporator coil. This line has a U-shaped trap, not unlike that under your sink, which prevents air from entering the closed system. However, this bend, combined with the warm, moist air under your air conditioner, is also an ideal breeding ground for algae. Left unchecked, this algae buildup can clog the condensate drain line and lead to leakage and overflow. Cleaning this line requires skill and knowledge of the system, so hiring an HVAC contractor to do it is much safer for you and your unit.

2. Electrical Problems

Any electrical issue is risky to troubleshoot. It could potentially be even more damaging when it involves your HVAC unit. Whether it’s your air conditioner, heater, boiler, or furnace, all of these are high-wattage appliances that could cause serious shock if mishandled. If your unit is not turning on, the only troubleshooting step you should do is to make sure that it is plugged in and to reset the circuit breaker. If it still doesn't run, you should call an HVAC contractor and let them fix the issue.  

3. Gas Leak

Even more so than electrical problems, gas leaks can lead to disastrous accidents, such as an explosion that can lead to a house fire. If you’re using natural gas for heating, you should keep your nose out for the distinct smell of gas or rotten eggs, which is a sure sign of a gas leak if it doesn’t go away. An HVAC contractor will be able to trace the leak and patch it up before anything unfortunate happens.
