When it’s time for a new AC or heating system, Sinclair Air Systems handles the full installation — from helping you choose the right equipment to making sure everything runs perfectly on day one. We serve homeowners across La Verne, Covina, Glendora, and the San Gabriel Valley.
We install central air conditioning, furnaces, heat pumps, and ductless mini splits. Every install starts with a proper size calculation so your new system matches your home — not too big, not too small.
A complete residential installation covers the condenser, evaporator, air handler, thermostat, and any ductwork modifications needed. We handle permits, disposal of old equipment, and a full system test before we leave.
Most AC systems last 15-20 years with proper maintenance. If yours is approaching that age, needs frequent repairs, isn’t cooling evenly, or your energy bills keep climbing — it’s worth getting a quote on a replacement. We’ll give you an honest assessment.
Even cooling throughout your home, lower energy bills with high-efficiency equipment, quiet operation, and a system that’s properly sized to last. We install all major brands including Carrier, Lennox, Trane, Rheem, Goodman, and Daikin.
We start with an in-home visit to assess your space and discuss your needs. You’ll get a written estimate with no hidden fees. Most installations are completed in one day. We test everything, walk you through your new system, and make sure you’re comfortable before we leave.
