A cooling system engineered, not swapped.
Most installs are box swaps. Ours start with measurements — Manual J load calc, duct evaluation, static pressure baseline — then we recommend the right Daikin or equivalent system for your home.
Start with a Performance Assessment.
The HVAC Performance Assessment is how every install at RJM starts. We come out, measure what your current system is actually doing, calculate what your home actually needs, and walk you through a flat-rate quote — no high-pressure sales tactics, no “box swap” surprises.
Regularly $279 — currently complimentary for a limited time for qualified Chester County homeowners.
We measure your home — not your old system. Right-sized for actual load.
Static pressure, CFM, and refrigerant charge measured and documented.
Real homeowners, real installs. Reviewed on Google.
For the ultimate peace-of-mind for as long as you own your home.
