Comfort should not depend on which room you are standing in. Master Construction is an HVAC contractor serving all of Ventura County, handling AC installation and replacement, furnace replacement, ductless mini splits, and the ductwork behind all of it. Family owned since 1994, our licensed team (Lic. #1027281) sizes equipment to your actual home instead of guessing, so it runs quieter, cheaper, and longer.
Right Sized Beats Oversized Every Time
The most common mistake in an AC replacement is stuffing in a bigger unit than the house needs. Oversized systems short cycle, wear out early, and leave rooms clammy. We calculate the real load based on your square footage, insulation, and windows, then match equipment to the number. It is the unglamorous math that separates comfort from complaints.
Installation details decide how long the equipment lasts. Line sets get brazed with nitrogen flowing so scale never enters the refrigerant circuit. The charge is weighed in and checked against manufacturer subcooling targets, not topped off by feel. Condensate lines get a proper trap and a float switch that shuts things down before water reaches your ceiling. Static pressure gets measured at the end, because a system that cannot breathe will not perform no matter what the sticker says.
What to Expect From Your HVAC Contractor
From evaluation to comfortable:
- Load calculation. We measure what your home actually needs before recommending anything.
- Options and pricing. Clear choices at different budgets, explained without jargon.
- Installation. Equipment, ductwork, and controls installed clean and to code.
- Commissioning. Airflow balanced, refrigerant charged to spec, and performance verified room by room.
- Walkthrough. We show you the system, the filters, and the thermostat until you are comfortable running it.
Ductwork, the Half of the System Nobody Sees
A new unit pushing air through crushed, leaky, thirty year old ducts is money out the register. We inspect, seal, repair, and replace ductwork as part of every changeout conversation, and as remodel contractors we route new ducts cleanly through attics and additions where standalone HVAC companies often will not go.
Coastal air is hard on condensers. Within a mile or two of the water in Ventura and Oxnard, salt eats coil fins and cabinet fasteners, so we spec coated coils and place units where rain can rinse them instead of tucked under an eave collecting spray. Permits matter too. Ventura County changeouts require Title 24 paperwork and third party HERS duct testing, and we pull the permit and schedule the test rather than leaving it for you to discover at resale.
