Different than most! Four Seasons Heating and Cooling is not only family owned but also owner operated. That means the owner will be answering the phone, greeting you at your home and looking over every detail of your project until it is 100% complete. Aaron is a 2nd generation HVAC journeyman with over 25 years experience in the HVAC industry. Much of his time was spent working for large commercial contractors in the Seattle area. Looking for a more family oriented lifestyle Aaron started the business in 2013. Shortly after the business started Aaron and his wife moved their family to Whatcom County and found Lynden to be the best place to raise a family. Aaron and his wife proudly serve the community they live, work and raise children.

"i would give them a 10, very trustworthy and responsive "

Heating Oil questions, answered by experts

HVAC systems usually last between 10 and 30 years, with most having a lifespan of around 20 years. Factors that impact a unit’s life expectancy include which brand you choose, how often you use it, and how well you maintain it. To make sure yours lasts as long as possible, make sure to keep it clean and schedule an annual service with an HVAC technician.

While it's generally safe to stay in a home with a coolant leak if your home is properly ventilated, it's important to have a professional come out to assess the situation right away. You should evacuate your home if you notice any powerful fumes. Additionally, you should leave your home if you are experiencing headaches or dizziness.

For most systems, an annual HVAC system service is more than enough. Some homeowners prefer a twice-a-year visit to ensure the system is ready for the upcoming summer and winter seasons. If you need to call an HVAC pro more often than this, it may be time to check if your system is getting old enough for a replacement.

There are three main types of heat pumps. An air-source heat pump system is the most common and has two parts—an indoor air handler unit and an outdoor heat pump unit. A ductless heat pump system functions similarly to an air-source heat pump system but doesn’t need ductwork to distribute the air. A geothermal heat pump system pulls heat from the ground to help heat your home.

The most obvious downside is the high upfront cost of buying and installing one of these systems. Additionally, sometimes the system can take a longer time to heat than alternatives like a boiler. Also, if something goes wrong with the geothermal pump, repairs are often significantly more expensive than repairing traditional, above-ground heat pumps.
