How Lion Stacks Up Against Other AC Companies
We remove the installed system and refund 100% if you’re not satisfied. No conditions and no fine print
Once installation is complete, most companies treat your satisfaction as your responsibility
A live person answers every call around the clock so you get answers when your system fails at night or on a weekend
Most companies send after-hours calls to voicemail, leaving you without support at the worst possible time
Every technician completes ongoing training and meets our internal quality standards before entering your home
Training levels vary widely, and many companies dispatch subcontractors who answer to no one on-site
We run a load calculation on every job and match the system to your home’s actual cooling demand
Many companies skip the calculation and install what’s easiest to source, which causes short-cycling and high monthly bills
Shoe covers and protective tarps on every job, every time, guaranteed
Cleanup is an afterthought for most crews, and damaged surfaces rarely get addressed
We donate a portion of profits to Northern Colorado organizations because Fort Collins is our home
Most companies treat this market as a revenue opportunity and reinvest nothing locally

Get Your Questions Answered
How do I know when to replace instead of repair?
If your system is 10 to 15 years old and needs repairs more than once a season, you’re paying to keep a failing system alive. We assess your unit honestly and tell you exactly what we’d do if it were our own home.
What determines the right system size for my home?
Square footage is only one input. Your home’s ability to hold temperature depends on factors specific to your structure. Duct condition matters. So does insulation. So does how much sun exposure your home gets. A wrong-sized unit short-cycles, driving up your monthly bill. We run a Manual J load calculation for every job to ensure sizing is right.
How long does installation take?
Most jobs are complete in one day. We confirm the timeline before we start and stay until the system runs correctly.
Do you offer financing?
Yes. Ask about financing when you schedule. We don’t want cost to keep you in an uncomfortable home any longer than necessary.
What warranty do I get?
Coverage depends on the system you select. We walk you through the manufacturer warranty and our own workmanship guarantee at the final walkthrough, in plain language.
