DIY Mini Split Installation: Should You Try It?
Installing a ductless mini split system can seem like an easy DIY win for Wichita, Andover, Maize, Augusta, or El Dorado homeowners — but should you really do it yourself? PD Plumbing, Heating & Cooling breaks down what you need to know.
🔧 What Makes DIY Mini Splits Tricky?
Many brands like MRCOOL DIY advertise ductless systems you can install yourself — but most installs still require drilling through walls, pouring a pad, wiring a dedicated 220V circuit, and handling refrigerant lines. Mistakes can cost you more than hiring a pro in the first place.
📏 Sizing & Cost: Don’t Guess
Sizing a mini split is not one-size-fits-all. Square footage, sun exposure, insulation, and layout all matter. Installing the wrong size means poor comfort, high bills, and early breakdowns. Our team does proper load calculations as part of every HVAC service.
🧰 DIY vs. Reality
Many YouTube installs are filmed by pros — not average DIYers. DIY kits can still miss essentials like wiring to a shut-off switch, line set vacuuming, or city permit sign-offs. Also, a DIY install may void your warranty.
💡 Good Spots for Mini Splits
- Sunrooms that get too hot
- Bonus rooms, garages, workshops
- Old window AC replacement
- Spaces far from ductwork runs
📋 Financing & Next Steps
Some homeowners try DIY to save money — but mistakes can mean hiring a pro later anyway. Instead, check our financing options. We make mini split installs affordable, safe, and done right the first time.
✅ Fixy’s Tips for DIYers
What if I buy my own system?
Some HVAC companies won’t install homeowner-bought units. Always check first — and know that manufacturer warranties often require pro installation.
Should I do the electrical work myself?
DIY mini splits still need proper electrical. If you’re not licensed, plan to hire an electrician and budget extra cost.
Where can I buy DIY mini splits?
Kits like MRCOOL DIY are popular for homeowner installs — but read the fine print!
