Whether it’s painting your home of crafting a wall art, DIY projects are always an adventure. That said, despite the excitement, there are some projects that you should not even attempt doing unless you are an expert.

DIY HVAC repairs and installations are some of those projects.

You probably want to understand why you should pay someone else to do something you can possibly learn online and carry out yourself, right? After all, the internet is riffle with DIY guides for just about any project so what could possibly go wrong?

Well, a whole lot of things and that’s exactly what we’ll be discussing in this post.

HVAC units are highly technical appliances that use high voltages of electricity, making HVAC projects some of the most dangerous jobs in the US.

Unless you know the ins and outs of dealing with such power, this is a do it yourself HVAC project you should simply avoid.

These appliances also use refrigerants and chemicals that you are possibly unfamiliar with. These chemicals may turn out to be deadly if proper precaution is not followed.

You need adequate training and the right safety gear to pull off such a delicate project. We can all agree that a high utility bill would be preferable to an injury or fatality to you or a family member.

2. Possible Health Problems for You and Your Family

Talking about injuries and fatalities, heating and cooling appliances come with substances such as carbon dioxide and carbon monoxide.

With one careless mistake, these fatal gases could be released into the air, risking the health of your entire family. Carbon monoxide poisoning is highly dangerous, so a DIY HVAC repair project is something you must stay away from.

In addition to this, faulty DIY HVAC repairs could compromise the efficiency of the appliance, increasing humidity and failing to filter out contaminants effectively.

These consequences can leave lasting effects on you and your family members by causing respiratory illnesses due to inhalation of unclean air.

3. HVAC Projects Require Specialized Equipment

HVAC professionals spend years studying and perfecting their trade before qualifying to service heating and cooling appliances.

This is not something one can learn from an internet tutorial and certainly not something to second-guess.

HVAC projects require trained and skilled individuals with the right tools. Carrying out an HVAC DIY repair project will be tricky if you don’t have the specialized equipment necessary to identify and rectify the problems. There is a high risk of creating an even bigger issue with the wrong tools while trying to fix it.

4. Small Repairs Can Easily Turn Into Major Ones, costing You More

Talking about bigger problems, you may misdiagnose your HVAC problems.

A problem may seem small and insignificant to you, but what you don’t know is that it may be a symptom of a much larger problem. You may be patching an issue that will eventually be more dangerous and more expensive in the long run.

When you hire an expert, on the other hand, you’ll be assured of the fact that they will diagnose the actual problem and solve it. They also have troubleshooting experience, and they may detect other problems that you may not notice during the repairs.

Besides this, they are likely to have more access to replacements parts that you may not find directly in the market.

5. DIY Repairs May Void Your Warranty or Lead to Legal Consequences

Most HVAC warranties require professional maintenance and repairs performed on the appliances.

Once you decide to do the project yourself, you’ll run the risk of voiding your warranty. Apart from this, there is a high chance that carrying out DIY HVAC projects may be illegal in your state.

The EPA, or Environmental Protection Agency, requires any person working with refrigerant to have the 608 certificates, which you don’t have and can only obtain through training. So apart from the health risk you face by dealing with refrigerant, you may also break the law while at it.

Purchasing refrigerant without these certifications may be illegal as well, and working on the HVAC system without proper training may lead to a fine or worse legal consequences. Professional technicians know to refill or dispose of refrigerant, and hiring one is a wise idea in this case.

6. You May Reduce Your HVAC Efficiency

Fixing heating and cooling appliances is quite tricky.

Your unprofessional diagnosis may leave it operating at a substandard rate. It’s easy to mess things up without the right knowledge, and these mistakes will lead to reduced efficiency and higher monthly operational costs.

A DIY HVAC repair project may seem financially savvy since you are trying to save on the professional costs, but it may compromise on your appliance capability.

7. You May Start a Fire

One of the primary reasons why you should opt for your local HVAC expert technician is the fact that you may cause a house fire. If you get a gas leak, an overheated unit, or even a short circuit, there’s a chance a fire could break out.

The appliance could even explode, leaving you with fatal injuries. You may feel that you are quite handy around your home and handle DIY projects quite like the pro, but in this case, saving a little money will not be worth the risk.

What Should You Do Instead?

Lack of skills and knowledge could leave your family in grave danger should you decide to embark on a DIY HVAC repair project. Working with a licensed and reputable HVAC technician will not only ensure your safety but guarantee successful repairs. You’ll avoid incurring extra costs with more repairs or possible replacements in the near future.

If you are considering purchasing a new unit, then a DIY HVAC installation should also be done by a professional. Installing a unit is just as delicate as repairing one, so just stay away from this one and let the pros handle it.
