VanDiermen and Sons Heating and Air Conditioning is proud to provide the following residential and commercial services in Langley, Aldergrove, Walnut Grove, Fort Langley, and all of Langley’s neighbourhoods and communities:

We are fortunate in Langley to experience all four seasons, which means both heating and cooling are essential for maximum comfort! Winter comes with cold winds, plenty of rain, and sometimes snow. Summer brings us warm, balmy days.  We want you to look forward to coming home to a warm, cozy vibe during those cold winter months, or to a refreshing oasis during those dog days of summer. We can help ensure you are ready to live in comfort through any weather in any season, by providing service, repair and installation of furnaces, heat pumps, water heaters, and air conditioning units.


Service and maintenance can help prevent costly repairs

Many of us take having temperature controlled homes for granted – until something isn’t working. Unfortunately, this often happens during the seasons that furnaces or air conditioners are needed the most. This also means, many breakdowns occur during our busiest seasons! You can prevent delays in service, and often costly repairs, by having your furnaces, boilers, water heaters and air conditioning units serviced on a regular basis. Many units have a service schedule sticker placed on the unit during installation. This schedule should indicate manufacturer recommended service intervals. If your heating or cooling appliance does not have a service schedule indicated, one of our knowledgeable technicians will be able to help.


To repair or replace your heating or cooling appliance, that is the question

Even with regular service and maintenance, nothing lasts forever. When a furnace, heat pump, water heater, or air conditioning unit does fail, the big decision becomes whether to repair it or replace it. The expected life of each appliance will have been estimated by that appliance’s manufacturer. Our VanDiermen and Sons technicians are able to complete a series of diagnostics to help you determine whether you have exceeded the life expectancy of your unit, recommending replacement, or whether a repair will be the correct choice for you.

We are a family owned company and have been serving Langley and area customers for three generations. All of our technicians are licensed and insured, with current gas tickets, and are ready to take care of all your heating and cooling needs.

VanDiermen & Sons Heating and Air Conditioning is an American Standard dealer, and a Fortis BC contractor (under our umbrella company, Fraser Valley Plumbing Services).

Fortis BC often has rebate programs available. Ask your VanDiermen & Sons Heating and Air Conditioning technician today which rebates are available for Langley residents. They can help walk you through your options, and any application required.
