When to DIY & When to Call an HVAC Professional

When your HVAC system breaks down, it can make living conditions unbearable. In the height of summer, your home or office will feel like an oven and during the cold winter months, it will be like living inside a refrigerator. Having your heating, ventilation and air conditioning system fixed can also be a costly affair, which is why many people choose to do the repairs by themselves.

Some minor problems can also be fixed without the intervention of an expert, but if you’re embarking on a DIY endeavor to fix your malfunctioning HVAC system, there are few key steps to follow:

Get a Filter Replacement

HVAC units come with filters that need changing on a regular basis. If the recommended time to change your filter has elapsed and your heating system is not working properly, then it might be time to get a replacement. Worn out or damaged filters can cause your system to overheat, which then causes it to shut down in order to protect the electrical components. Other systems simply go into ‘safe mode’ by leaving the fans running but with no effect on air temperature.

Check the Fuse

This is perhaps the easiest and least expensive fix when it comes to repairing HVAC units on your own. There is a good chance that your system has just blown a fuse during a power surge. If this happens to be the problem, simply replace the fuse in your circuit breaker box. Make sure to purchase a fuse with the same Ampere rating as the previous one, to prevent the problem from reoccurring.

Inspect the Ductwork for Obstructions

All kinds of debris can get into the ductwork of your central HVAC system. This includes items like drapes, curtains, bed sheets, tree sap, leaves and branches. These obstructions can disrupt airflow and heat circulation while the HVAC systems are running, thus rendering them ineffective. As a result, you may want to check your ventilation and heating unit for blocked vents to clear any obstructions that are within reach.

Test Your Thermostat

Having problems with erratic temperature fluctuations? You might just have a malfunctioning thermostat in the HVAC system. To test the thermostat, simply take temperature readings with a thermometer - any disparity means that your thermostat requires recalibration. If this occurs, then you can call a professional to recalibrate your system or follow the instructions in the manufacture’s manual if you want to do it yourself.

Did None of the Above Steps Work? Call a Professional!

If the handyman in you is not up to the task when facing a highly technical problem, then it is advisable to call in the experts rather than trying to tackle the issue on your own. In addition, it makes sense to call a HAVC expert to perform repairs when you are pressed for time, or are afraid that any DIY fixes could void your warranty.

How will the Previous DIY Tricks Help You When a Professional Checks Your HVAC system?

By following the steps mentioned above, you can gain more knowledge about your HVAC system and make an informed choice on whether to seek professional help. Perhaps more importantly, you may have taken care of smaller repairs or maintenance that cuts down your bill when you call a professional for help with the rest.

You can also be sure you’re paying the correct charge for service, parts and other functions, since the knowledge you’ve gained will provide more insight on the overall cost of repairing the system!
