The AC installation process with Oasis Heating and Cooling moves from an in‑home assessment to a final performance check and homeowner walkthrough. Most jobs begin by right‑sizing the system and aligning it with your comfort goals, budget, and whether central, ductless, or a heat pump is the better fit.
- Assessment and options: evaluate the home, discuss airflow, noise, and air quality add‑ons like smart thermostats or dehumidifiers; provide a clear proposal with choices and 60‑month financing with approved credit.
- Schedule and prep: set a convenient date; protect floors and work areas; for ductless, installs are non‑disruptive with only a small exterior wall opening.
- Install and connect: remove old equipment; place new indoor/outdoor units; run refrigerant/electrical/drain lines; configure controls; retrofit expertise supports homes and light commercial spaces.
- Start‑up and verification: pressure test, charge, and confirm cooling performance; review operation and maintenance plans, including our Energy Savings Program.
Our crews regularly complete installations for homeowners and small businesses across the Evanston area. Schedule a professional assessment before peak heat to avoid rushed choices.
