An air conditioner is a cooling-only system that removes heat from indoor air using a refrigerant cycle and an outdoor condenser unit. Central AC ties into your existing forced-air ductwork; ductless mini-splits cool one or more rooms without ducts. John Sadler Plumbing & Heating installs both, and only both — we focus exclusively on new AC installs across Surrey, White Rock, Langley, Delta and Aldergrove, including South Surrey, Cloverdale, Walnut Grove, Crescent Beach, Ocean Park, Morgan Creek, Grandview Heights, Elgin, Brookswood, Murrayville and North Delta.
We are a Navien Service Specialist — recognized across Canada — and we install the complete Navien dual-fuel HVAC system, which pairs the Navien NAZ heat pump with the NAM cased coil and the NPF Hydro-furnace for cooling in summer and efficient hybrid heating in winter.
We do one thing on the AC side: we install new systems correctly the first time. Every AC job at Sadler goes to a team that does this work every day — not a service tech squeezing it between repair calls. That focus is why our installs come in clean, on schedule, and properly sized for your home’s load. If you need an AC repair, we’ll point you to a trusted local repair contractor.
Central air conditioning is the right choice when your home already has forced-air ductwork from a furnace. The outdoor condenser ties into the existing duct system and cools the entire home from one thermostat. Properly sized, a central AC is the most cost-effective way to cool a Surrey or Langley home of 1,500 sq ft or more.
Ductless mini-splits are the right choice for homes without ducts, for additions, suites, stratas, or for room-by-room comfort control. Each indoor head can be controlled independently, which makes mini-splits a strong fit for Crescent Beach and Ocean Park homes that often have additions and converted basements.
The Navien NAZ heat pump as a 2-in-1 system cools in summer and heats efficiently in winter. For most Lower Mainland homes that already have natural gas, the Navien dual-fuel pairing (NAZ + NPF Hydro-furnace) is the highest-value path because it uses the heat pump down to roughly +5 °C and the gas furnace below that — capturing the rebate dollars while staying warm during a January cold snap.
For most homes in South Surrey, Cloverdale, and Walnut Grove, a properly sized central AC paired to the existing furnace is the lowest-cost path to whole-home cooling. For White Rock, Crescent Beach and Ocean Park — where coastal salt air affects equipment lifespan — we recommend coastal-rated condensers and a slightly oversized outdoor pad. For Langley Township and Aldergrove, where lots are larger and homes often have additions or detached suites, ductless mini-splits or a hybrid central + ductless layout often make more sense than central alone.
Step one is a load calculation — Manual J — to size the system to your home, not to the old furnace. Wrong sizing is the single most common AC install mistake; it cuts efficiency, shortens equipment life, and creates humidity problems. Step two is equipment selection. Step three is the rebate paperwork — we handle the CleanBC, BC Hydro and FortisBC applications so you don’t lose money to missed deadlines. Step four is the install itself, typically one to two days depending on whether ductwork modifications are needed. Step five is the commissioning check and the warranty registration.

No — John Sadler installs new AC and heat pump systems only. We do not offer AC repair or AC maintenance. We continue to repair boilers, furnaces and hot water tanks. If you need an AC repair, we’ll happily refer you to a trusted local repair contractor.
Most Surrey homes built since the 1980s with forced-air furnaces are compatible with central AC. The two key checks are: (1) electrical service capacity — older 100A panels sometimes need an upgrade — and (2) outdoor space for the condenser pad. We confirm both during the in-home assessment.
We install all leading central AC and ductless mini-split brands and we are a Navien Service Specialist for the Navien NAZ heat pump dual-fuel system. We’re brand-agnostic on selection — we recommend whatever sizes correctly for your home and best fits the rebate program you’re applying to.
Most central AC installs are completed in one to two days. Ductless mini-split installs are typically one day per zone. Navien dual-fuel systems take two to three days because the install includes the heat pump, cased coil and Hydro-furnace.
Pure cooling-only AC does not qualify for most BC rebates because the rebate programs target heating efficiency. However, **the Navien NAZ heat pump (which cools and heats) qualifies for CleanBC, BC Hydro and FortisBC rebates** — typically $4,000–$11,000+ in combined rebates for a complete dual-fuel install. We complete and submit the rebate paperwork on your behalf.
Yes. We install AC and heat pump systems in residential stratas across Surrey, White Rock and Langley, including high-rises up to 4 stories. Strata council approval and electrical/structural review are required up front; we coordinate the documentation.
