Reasons Why You Shouldn’t DIY HVAC Installation and Maintenance

DIY projects are a fun way to use your free time and challenge yourself to new experiences. However, among the thousands of DIY projects in this category, there are some projects you shouldn’t attempt unless you are a professional.

HVAC installation and repair are among those projects. Even if you are a skilled DIY enthusiast, you should think twice before repairing your HVAC unit. Modern units have complicated hardware and technologies that non-professionals cannot engineer. Consider working with heating and cooling experts for the following reasons:

1. Requires Special Equipment

Installing, maintaining, and repairing HVAC systems requires special tools and equipment that professionals can only handle. Unfortunately, simple tools such as a screwdriver and pliers won’t be of any help. HVAC manufacturers produce complicated, high-end tools specifically designed for HVAC units.

2. Potential Health Problems

HVAC units directly affect your indoor air quality. Therefore, assuming the role of HVAC maintenance and repair means you directly influence the quality of your indoor air. For starters, improper installation of heating and cooling units decreases their efficiency by 30%.

Additionally, it has lasting effects on indoor air quality and your general family’s health. Poor indoor air quality causes respiratory issues, including asthma, due to inhalation of polluted air. Even experienced DIY people are not sufficiently trained to perform what installation experts can do.

3. It Is Illegal

The drawbacks of DIYing your HVAC installation and maintenance also extend to legal fronts. Most homeowners perceive HVAC installation and repairs as simple tasks that don’t need certification or permission. Like any other household installation or maintenance tasks, you should be permitted by the government to conduct HVAC installation and maintenance.

The EPA (Environmental Protection Agency) requires that anyone handling refrigerant, which is found in air conditioners, should have EPA 608 certification. You can only obtain this certification after specific rigorous training programs.

4. HVAC Repairs are Dangerous

Unlike other simple home maintenance tasks, HVAC installation and maintenance come with plenty of safety issues. For starters, HVAC units are very technical and use large amounts of electric currents. You should avoid such electricity levels if you don’t have sufficient knowledge.

Heating and cooling systems also use chemicals and refrigerants. While you may know about these chemicals, handling them is risky if you don’t follow the right precautionary measures. Safety gear and adequate training are important to ensure that you or other family members aren’t exposed to these deadly chemicals.

5. Minor Issues Can Lead to Costly Problems

What appears to be a small HVAC issue may indicate a serious impending problem. What’s more challenging is making an accurate diagnosis of the small problem. If your unit has an issue, you should have it checked out by a qualified technician. Patching the issue without thorough expert assessment can lead to costly repairs and inconvenience.

Handling HVAC installation and maintenance on your own is not a good idea. Apart from the possible consequences mentioned above, you will also void your warranty. Heating and cooling units are costly, and voiding your warranty means the manufacturer won’t be liable for future replacements.
