Short answer: before you order, confirm the size, the electrical requirements, what's included in the box, that the parts match, the cold-weather rating, and the warranty terms. Then send the model number to your installer.
More homeowners are buying their own air conditioners, mini-splits, furnaces, and heat pumps online or at big-box stores, then hiring a pro to install them. It can save money, but only if the unit is the right one for your home. Here is what to check first.
1. Get the size right
Square footage gets you in the ballpark, but ceiling height, insulation, windows, sun exposure, and the floor your room is on all change the answer. A unit that is too big short-cycles and leaves a room clammy. One that is too small runs nonstop. For mini-splits, start with our mini-split sizing guide for Northeast PA homes.
2. Match the electrical requirements
Every unit has a nameplate or spec sheet listing its voltage and the circuit size it needs. Check those numbers against your electrical panel and where the outdoor unit will go. Many installs also need a disconnect near the outdoor unit. Send us the model number and we'll tell you what the electrical side involves.
3. Check what's included in the box
Equipment listings don't always include everything. Line sets, wall brackets, pads, disconnects, and condensate pumps are often sold separately. Many mini-splits also ship pre-charged for a set line set length, so a long run between the indoor and outdoor units can change the install. Read the parts list before you buy.
4. Make sure the parts match
For central air, the outdoor condenser and the indoor coil need to be compatible with each other. If you're replacing only one half of a system, confirm the other half works with it. New residential equipment also uses newer refrigerants than older systems, so don't assume an old line set or component carries over unchanged.
5. Check the cold-weather rating
Lackawanna, Luzerne, and Wayne Counties have real winters. If a heat pump or mini-split will heat your home, look for a cold-climate model and check its capacity at low temperatures, not just its cooling rating. Our mini-split page explains more.
6. Read the warranty
Warranty terms vary. Some manufacturers set their own installation or registration requirements, so read yours before you buy and keep your model and serial numbers. The equipment warranty is between you and the manufacturer or seller. We can't warrant equipment we didn't supply.
7. Inspect it when it arrives
Check the unit for shipping damage as soon as it arrives, and keep the paperwork. Problems are easier to sort out with the seller before the install than after.

Frequently Asked Questions
Can I buy a mini-split online and have it installed?
Yes. Many homeowners buy their own equipment and hire a pro to install it. We install customer-supplied mini-splits, air conditioners, furnaces, and heat pumps in Lackawanna, Wayne, and Luzerne Counties.
What is the most common mistake when buying HVAC equipment online?
Buying the wrong size. Square footage is only a starting point, and a unit that is too big or too small won't keep your home comfortable. Check the size with a pro before you order.
Does buying equipment myself affect the warranty?
It can. Warranty terms vary by manufacturer, and some set their own installation or registration requirements. Read the warranty before you buy. The equipment warranty is between you and the manufacturer or seller, and we can't warrant equipment we didn't supply.
