Why Do-It-Yourself HVAC Repair is
Not Advisable

There are some things you can DIY. For intricate air conditioner repair, it’s best to call a trained professional. Here’s why.

In this technological age, knowledge is right at your fingertips. Maybe you’ve replaced TV screws or changed your vehicle’s oil off internet articles and videos. It’s fantastic and beneficial to learn new skills and utilize them. In certain circumstances, DIY solutions may be appropriate.

However, a few videos or internet references can never replace in-depth training and experience. Serious issues involving HVAC equipment require an experienced hand. Tim Benjamin Air & Heat offers AC repair services in Oviedo, FL, to keep you safe and your house functioning properly.

The Dangers of Do-It-Yourself HVAC Repair


Contact With Hazardous Materials

Air conditioner repair isn’t just unscrewing nuts and bolts. When working on an HVAC unit, professionals have the tools and training to deal with the hazardous equipment and materials inside of the system. Air conditioner technicians must have training, qualifications, and national certification to work legally. DIY attempts lack the same nuance, education, and legality. 

Failure to properly handle the chemicals in air conditioner refrigerants can lead to severe reactions. Moreover, it is against the law to handle hazardous AC materials without a proper license. For example, technicians must be EPA 608 certified to handle and dispose of AC refrigerants. 

Some HVAC components release toxic fumes if not handled properly, and they can filter into your circulated air. Additionally, if any DIY repairs cause hazardous leakage, it could poison you and anyone living with you. Certified technicians train to ensure you and your household stay safe. 

Inadequate Electrical Management

The electrical connection to the HVAC unit needs proper disconnection during repairs. Neglecting this vital step is dangerous. Any videos you watch may not show you each intricate part or how to deactivate it in detail. For instance, if parts of the unit regain power while removing the fan from inside, you could sustain severe (even lethal) injury.

Additionally, not properly disconnecting the unit from its power sources means you could be electrocuted at any time. The voltage powering your AC is enough to kill a grown human. If you do not have the right tools and knowledge to prevent electrocution, you are at risk of lethal harm.

HVAC Unit Damage

Sometimes, trying to fix the problem without professional help makes things worse. You may have a general idea of which parts within the unit may have issues. However, without the right equipment and knowledge, you may try to fix something that never needed tampering in the first place.

For example, your air conditioner is blowing hot air, and your DIY source advises you to check the condensing unit. Checking the condensing unit brings you in contact with AC refrigerant, and damage to the condenser will likely necessitate a new one. Moreover, the problem could have been with the air handler inside the house rather than the outside unit. 

Damaged HVAC parts increase costs. Also, many critical HVAC parts are purposefully not sold at retailers due to licensing needs. A professional would know where and how to find the actual source of the problem. They would also have access to the avenues to obtain the needed replacements.

Voided Warranties and Insurance

Your warranty or insurance won’t likely cover any damage resulting from a do-it-yourself HVAC repair attempt. If anything, it may be grounds to void either or both policies. As such, you can no longer receive any warranty-covered assistance with your HVAC unit. Your homeowners insurance will also refuse to reimburse you for repairs or replacement, meaning you must pay out of pocket.

Warranties help reduce equipment and part costs, and some homeowners insurance policies may help cover those expenses. Voiding these policies costs you money and removes protective coverage.

Legal Ramifications

Because handling parts inside the HVAC system requires certification, doing so without it puts you at the odd end of the law. You could face fines or even jail time depending on the damage caused by your DIY repair attempt. You will likely be found responsible by law for anyone harmed by the results of your repair attempts.

Professional HVAC technicians are insured and qualified to work with your system and keep it up to code. Instead of paying for a professional, you could pay hundreds or thousands in fines and bail. The risk is never worth it.

Some Things You Can Do

While do-it-yourself HVAC repair is strongly ill-advised, you can manage some minor aspects of your heating and cooling system. For example, you can change the air filter without calling in a professional every time. Having a consistent schedule for checking your air filter can improve your air quality and health. 

We also recommend cleaning around your HVAC unit. While you shouldn’t turn the unit off and clean the inside, feel free to keep the area around the outside of your system clean and free of obstructions. If your system gets clogged with debris, it won’t work properly or as long as it should.

You can also check on the thermostat. Sometimes the batteries need to be replaced, especially if the display is not turning on properly. If you have the manual, you can find what size batteries are required. 

Not everything requires a professional hand. For the little things, your initiative saves you stress and money. Let us handle the rest for you.
