The Disadvantages of DIY HVAC Installation

HVAC installation

Did you know that 87% of homes in the U.S. have air conditioning? Even so, the demand for HVAC installation is rising by the day.

Having an HVAC installation service that you can rely on helps you stay indoors comfortably even when temperatures rise or lower to the extreme.

Buying the wrong size of HVAC unit can cause short cycling, reducing the lifespan of your air conditioning system.

You must ensure that your HVAC system is routinely maintained for maximum performance and efficiency. A well-maintained air conditioning unit can give you up to 15 years of service.

Some people call for professional repair services when maintaining or replacing their AC units. Others choose to give it the DIY approach.

Read on as we discuss the disadvantages of DIY HVAC installation.

Compromised Safety

Poor HVAC installation is hazardous and can cause a permanent injury or death. High electrical voltage and toxic combustion fumes are some of the dangers of poor AC unit installation.

You’ll not only pose safety risks to yourself but also to your family members.
Besides, you can damage the HVAC unit causing it to malfunction. This may lead to your warranty getting nullified and cost you even more in replacement costs.

HVAC wholesalers and retailers hardly sell tools or parts necessary to repair an AC unit. You should consider looking for a professional for your HVAC installation and repair even if you manage to get the required components.

Wastage of Time and Money

DIY HVAC installation can make you feel like you’re saving money, but that’s misguided. You may end up purchasing parts that you don’t need and spending more time than necessary on the project.

Most professional contractors work with parts companies and HVAC manufacturers. So they can get discounts on spare parts, repair tools, or a new HVAC unit.

Thus, it allows your repairman to offer cheaper services than it’d be when finding and buying the items on your own.

Regulations and Laws Guiding HVAC Installation

You might need to get a license when removing or installing a central air conditioner in many cities and suburbs. The process of collecting the correct paperwork and permits is time-consuming and burdensome. So it can interfere with your DIY HVAC installation guide.

It would help if you considered hiring a licensed HVAC technician that’s up to date with local laws and regulations. They will help you get the required permits quickly and fix your air condition system, thus saving you time.

Physical Labor

DIY HVAC installation requires moving heavy equipment, mixing concrete, and replacing the central thermostat. Besides, air compressors and their housing are often heavier than you may realize.

Old HVAC compressors can also be challenging to remove due to rusted bolts and connectors. You must have a specialized set of tools to remove an old air conditioning system in your home correctly.

These tools help to safely detach the refrigerant lines and compressor in your outdoor condensing unit.

Types of Refrigerant

The refrigerant liquid in your AC unit will vary depending on its age. R-22 refrigerant is common in old-aged AC units, and the non-polluting R-410A refrigerant is common in modern ones.

It’s hard to do DIY HVAC repair on an old AC unit using R-22 refrigerant. You’ll need to look for a professional when replacing to prevent the release of Ozone-Depleting Substances (ODS) to the environment.

Environmental Protection Agency Guidelines

You must pass a test and earn a certification from the Environmental Protection Agency to legally remove or install a central air conditioner. The certificate assures that you have the required skills to handle refrigerant and Ozone-Depleting Substances (ODS).

The assessment from Environmental Protection Agency is not complex. However, you must pay some fee to qualify for the exam.

It’s advisable to look for licensed HVAC installation services to avoid the risks of legal issues with a DIY HVAC installation.

Hazardous Electrical Connections

All the parts in your AC unit rely on electric power to function. You’ll have to integrate your new HVAC unit into the electrical panel in your utility closet when replacing the old air conditioning system in your home.

It’s advisable to avoid DIY HVAC installation to prevent electrocution or a house fire if you’re unfamiliar with wires and electricity.

Determining the Manual J Heat-Gain

You must be knowledgeable about the process of Manual J heat-gain calculation to perform AC installation. This process determines the suitable heat-gain rating and the size of your air conditioning system.

You can have a proper skill set as an average homeowner. But you’ll need appropriate licenses and tools to perform a DIY air conditioning installation project.

Reduced Efficiency

Poor DIY HVAC installation can lead to an air conditioning system that operates at low efficiency. Poor maintenance or repair quality affects the performance of your AC unit. Besides, the life expectancy of your air conditioner decreases.

It will also cause your energy bills to increase. This translates to an increased monthly operating cost.

Poor Air Conditioner Inspection

When performing a DIY air conditioning installation project, it’s challenging to determine if you have the right-sized AC unit. A professional technician undergoes training to determine if your AC unit is short cycling.

An HVAC unit that activates and deactivates frequently indicates it’s too big for your home. An air conditioner that’s too small for your home undergoes continuous cycles to maintain a low temperature and humidity rating.

The technician can also measure the humidity in your house and guide you to repair or replace your air conditioning system.

Hire a Professional For Your HVAC Installation

Knowing the best HVAC installation services from the many in the market is not easy. You’ll need to look for an experienced HVAC installation technician to get quality services.

Keep in mind your budget and what you wish to spend when looking for an HVAC contractor.

While you might be good at DIY HVAC installation, you’ll need a licensed air conditioning contractor for your AC installation services.

    Jessie Holloway Thanks so much for pointing out that you might need to be licensed to install an HVAC system, making hiring professionals the better solution than trying to DIY. My parents are wanting to replace their HVAC system before winter because their furnace hasn't been working properly. We've been looking into getting professionals to come to replace it because we don't know enough about the system to efficiently replace it ourselves. Reply

    completecomforthampton Proper HVAC systems are a worthy investment for any business or building owner because it gives you energy savings. HVAC systems today are automated, which means you no longer have to manually adjust the temperature settings or the time settings of each machine. Given that your entire HVAC system operates in an automated system, proper adjustments will be made right when they are needed. Reply

    Victoria Addington It captured me the most when you mentioned that most AC installation services can get discounts on spare parts for an HVAC unit. My friend needs their new AC unit to be installed. I should advise her to hire a contractor that works with parts companies. Reply
