Air Conditioning Installation

A comfortable, efficient home starts with the right system and a careful installation. We design and install central air, ductless mini-splits, and heat pumps with proper sizing, clean workmanship, and a full commissioning so your new AC delivers quiet, even cooling for years.

What You Get with a Proper Install

Load calculation (Manual J). We size equipment to your home’s actual heat gains—insulation, windows, shading, and occupancy—not rule-of-thumb guesses.

Duct evaluation (Manual D). Static pressure, return sizing, and leakage checks to ensure the blower can move air quietly and efficiently.

Right equipment match. Single-stage, two-stage, or variable-speed options with compatible indoor coils and blower motors.

Lineset & drain work. New or flushed linesets, proper traps and fall on condensate drains, and overflow/float protections.

Electrical & safety. Code-compliant disconnect, whip, fusing, and surge considerations for sensitive electronics.

Commissioning. Nitrogen pressure test, deep vacuum to target microns, charge by weight and fine-tune by subcool/superheat, and a documented start-up report.

System Types We Install

  • Central split systems — classic whole-home comfort with a matched indoor coil/air handler and outdoor condenser.
  • Ductless mini-splits — efficient zone cooling without ductwork; great for additions, attic spaces, or multi-family.
  • Heat pumps — year-round comfort with electric heating and cooling; excellent humidity control and efficiency.

Sizing & Efficiency — Getting It Right

Bigger is not better. Oversized units short-cycle, waste energy, and leave humidity behind. We size to the load and match blower performance to your ducts. For efficiency, we discuss SEER2/EER2 ratings, staging, and smart controls, then balance first cost with operating cost and comfort. If incentives or tax credits are available, we’ll outline options.

Our Installation Day, Step by Step

  1. Protect floors/work areas and remove old equipment.
  2. Set pad or hanger supports; place and level new equipment.
  3. Install/flush refrigerant lines; pressure-test and evacuate.
  4. Connect drains with proper slope, trap, and safety float switch.
  5. Wire low/high voltage; install new disconnect and fusing as required.
  6. Charge and verify with manufacturer specs (subcool/superheat).
  7. Commissioning: temperature split, static pressure, and airflow checks.
  8. Walkthrough on operation, filter changes, and maintenance schedule.

Options to Improve Comfort & Air Quality

  • Media filters or cabinet upgrades for cleaner air and longer filter life.
  • UV or polarized air cleaners for coils and recirculated air.
  • Dehumidification/ventilation strategies for muggy summers.
  • Zoning or duct improvements to fix hot/cold rooms.
  • Smart thermostats and sensors for better control.

After the Install: Care That Protects Your Investment

Plan on a spring check each year (AC tune-up). Clean coils, correct charge, and a healthy drain line prevent efficiency loss and mid-season breakdowns. Most manufacturers offer up to 10-year parts coverage with timely registration; we’ll help you with the paperwork.

AC Installation FAQs

How long does an AC installation take?

Most single-system projects take one day. Duct changes, attic/roof access, or multiple systems can extend the timeline.

Do I need to replace my air handler or furnace?

Not always. We test blower performance and compatibility. If the existing air handler can’t deliver airflow or uses incompatible refrigerant components, we’ll recommend updating it.

What size AC do I need?

We run a Manual J load calculation and verify duct capacity. Correct sizing improves comfort, humidity control, and efficiency.

Do you pull permits and meet the inspector?

Yes, where required. We install to code, handle permits, and provide commissioning data at inspection.
