Is It Time to Replace?
-
10–15+ years old or frequent, costly repairs
-
R-22 legacy equipment (obsolete refrigerant) or major refrigerant leaks
-
Poor comfort: hot/cold spots, high humidity, or short-cycling
-
Rising energy bills vs. previous seasons
-
Noisy outdoor unit or failing compressor/fan motors
We’ll provide a repair vs. replace comparison with lifecycle costs so you can decide confidently.

-
In-Home Assessment & Sizing
Room-by-room Manual J, duct inspection, return/supply balance, electrical review, and line-set routing. -
Equipment Matching
Good/Better/Best options with SEER2/EER2 ratings, sound levels (dB[A]), coil match, and furnace/air-handler compatibility. -
Code-Compliant Installation
Pad or wall mount, new or flushed line-sets, condensate management, electrical disconnect, and permits. -
Refrigerant Best Practices
Nitrogen pressure test, deep vacuum to ≤ 500 microns, factory weigh-in charge, and superheat/subcool verification. -
Commissioning & Training
Airflow & static-pressure checks, temperature drop across the coil, thermostat/app setup, owner walkthrough, and cleanup. -
Protection & Support
Manufacturer warranties + our workmanship guarantee, optional Air Conditioner Protection Plan, and priority service.
-
Ducted Central AC
Whole-home comfort with your existing furnace/air handler; excellent with 4–5″ media filtration and smart controls. -
Ductless Mini-Splits (Single/Multi-Zone)
Ideal for homes without ducts, room additions, or targeted cooling; whisper-quiet indoor heads and high efficiency. -
Inverter/Variable-Speed vs. Single/Two-Stage
Inverter systems modulate capacity for superior humidity control, quieter operation, and lower energy use.
-
Smart Thermostats (ecobee) for schedules, geofencing, and energy insights
-
Filtration: MERV 8–13 media cabinets for cleaner coils and air
-
Humidity Control: Whole-home dehumidifiers/humidifiers for year-round comfort
-
Ventilation: HRV/ERV systems bring in fresh, filtered outdoor air
-
Good: High-efficiency two-stage AC, ECM blower, quiet outdoor fan
-
For: Solid performance, improved comfort vs. builder-grade
-
-
Better: Inverter AC with higher SEER2/EER2 and enhanced dehumidification
-
For: Lower bills, steadier temps, quieter operation
-
-
Best: Premium inverter with ultra-low sound, advanced humidity control, smart bundle
-
For: Maximum comfort, efficiency, and noise reduction
-

How long does replacement take?
Most replacements are completed in one day, including removal, installation, testing, and cleanup.
Do I need new ducts?
Not always. We test airflow/static and recommend only the duct changes (e.g., added returns or sealing) that improve comfort and protect your new system.
Will an inverter AC really lower bills?
Inverter systems modulate capacity for longer, quieter cycles and better dehumidification—often reducing energy use versus single-stage units.
Can I reuse my existing line-set?
Sometimes. We inspect, flush, or replace as needed to meet manufacturer specs and protect the compressor.
Do I need a new thermostat?
Your current thermostat may work, but smart thermostats unlock better scheduling, comfort, and insights—especially with multi-stage/inverter systems.
Are rebates available?
Yes—programs change periodically. We confirm eligibility and submit applications on your behalf.
Keep it running like new
Add our Air Conditioner Protection Plan for annual tune-ups, priority service, repair discounts, and refrigerant/condensate system checks. Preventive maintenance extends equipment life and keeps cooling efficiency high.
