Central Heating and Air Conditioning in Chilliwack, help maintain the comfort of our homes. We experience all four seasons in our valley, with hot summer days, and cold winter nights. Nothing beats cozying up with a book or a new show, in your nice warm house on a cold, chilly day, or walking into a fresh, cool kitchen on a sweltering afternoon. However, while heating and air conditioning are comfortable home features, they are also essential to safety during extreme weather events.

At VanDiermen and Sons Heating and Air Conditioning, we provide installation, service, and repair of furnaces, boilers, hot water tanks, and air conditioning units in Chilliwack homes. Our technicians are certified and hold current natural gas fitting certificates. We guarantee that they are trained, skilled, and experienced when it comes to working with your natural gas appliances.

Heating and Air Conditioning Service

You can help prevent heating or cooling emergency situations by having your heat and air conditioning appliances serviced at regular intervals. Most installers will include a service schedule recommendation for each appliances, and often place a maintenance sticker on your furnace, water heater, or boiler unit. If you don’t have one of these stickers and don’t know when your appliance was last serviced, give us a call, and we will send a technician out to your home in Chilliwack. He will complete a service, provide a recommended service schedule, and place a sticker on your appliance to help you track your heating and air conditioning services.


Heating and Air Conditioning Repair

Even with consistent service, parts on your heating and cooling appliances will wear down over time. Our VanDiermen and Sons Heating and Air Conditioning technicians here in Chilliwack, have years of experience in diagnosing issues and repairing all necessary parts to get your appliance in great working condition again.


Furnace, Boiler, Water Heater, and Air Conditioning Replacement

Each heating and air conditioning appliance does come with an expected lifetime. Often, once a unit reaches the end of its expected useful life it makes more sense to replace the appliance than to repair it. Your technician will be able to help you determine which is the best, most cost efficient option for you. If a replacement is recommended, your heating and cooling technician will be able to walk you through the options that will work best for your home.
