You’ll Need to Handle Refrigerant
Cracking open the walls and fishing wires through may not be difficult for the savvy DIYer, but handling refrigerant? That’s another story. Only EPA-certified technicians are able to purchase refrigerants, since they are ozone-depleting substances. If you do get your hands on refrigerant, you’ll need to be careful. The rules and regulations for managing it are complex.
You May Pay More
Botched ductless air conditioning installation do-it-yourself projects aren’t uncommon. And a failed DIY project can cost double what you would have spent to hire an expert in the first place. Hopeful home installers may become overwhelmed by the cost and time it takes to complete an installation project. Calling in an expert at this point can be more expensive than going with one from the start.
You Need the Right Size
Choosing the proper ductless air conditioner for your project is far more complex than just measuring square footage. You might have two rooms with the same footprint, but if one has a gas stove and picture windows, you’ll need a bigger HVAC. A certified technician can perform Manual J load calculations to take climate, windows, and other factors into account so your system works properly.
Small Errors = Big Consequences
Many people choose ductless air conditioners because they offer significant benefits. They’re less expensive to install (even when you aren’t taking a DIY approach). ENERGY STAR certified ductless mini-split heat pumps can cut cooling costs by 30%. They also use 60% less energy than other heating systems. That’s a real savings…
…if they’re properly installed. You won’t see those benefits if your ductless air conditioner isn’t affixed well. Small gaps and cracks let that air – and those cost savings – leak out.
