Whenever something goes wrong with your A/C system, your first impulse is to call a trusted pro. But what about those other times when you're tackling basic maintenance? Keep in mind that there are certain tasks that are perfect for the average DIYer and others that require a licensed and experienced technician.
Tasks That Need a Professional's Touch
Instead of struggling with the following service tasks, you're better off leaving these tasks in the hands of a seasoned A/C expert:
A/C coil replacement – A rusted, weakened A/C coil will need professional removal to minimize damage to other components and reduce the spread of leftover debris. Expert installation is also essential for good A/C performance.
Faulty wiring repairs – Electrical issues can cause your A/C system to constantly blow fuses or trip the circuit breaker repeatedly. Given the risk of electrocution and severe equipment damage if handled incorrectly, you're better off letting a professional deal with wiring repairs.
Refrigerant replacement and leak repairs – The act of handling refrigerant isn't just dangerous – it's also prohibited unless you're properly licensed. Poor handling can also result in refrigerant being released into the atmosphere, which could have harmful effects on the ozone layer.
A/C unit relocation – Physically moving an otherwise-permanent A/C installation isn't for the faint of heart. It's a complex process that requires the knowledge and skill of a seasoned technician.
Another good time to call on an A/C expert is if you have any questions about your A/C system. If you don't feel confident about doing simple maintenance tasks, you can always have your technician take over and get the job done right.
Tasks You Can Tackle On Your Own
Parts of your A/C system may be off-limits when it comes to DIY work, but there's still plenty you can do on your own to keep unit in excellent shape. Filter changes are the perfect A/C maintenance task for any DIYer, for instance. Besides being easy to change in a short amount of time, swapping your old A/C filter for a fresh replacement also makes it easier for your A/C system to keep your home cool.
Here are a few other DIY tasks you can do:
Basic cleanup and debris removal – Thoroughly inspect the inside and outside of your A/C system and remove any debris you find.
Thermostat checks and upgrades – Make sure you're using the right settings on your thermostat and that your A/C system reaches its temperature set points. You can also upgrade to a programmable thermostat, if you haven't already.
Register and vent checks – Carefully inspect all supply and return air vents and registers for signs of dust and debris buildup. Clogged vents can block airflow, resulting in reduced cooling, increased wear, and higher utility costs.
Fuse and circuit breaker checks – Make sure your fuses are intact and accounted for inside the fuse panel. The same goes for the circuit breakers used by your A/C system.
