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 and Air Conditioning questions, answered by experts

If you’re trying to buy a new AC unit, there are a few crucial factors to consider. Look at the cooling capacity, the available warranty, the energy efficiency, and the type of unit. A ductless unit will cost more up front but may be a more viable option if you don’t already have ductwork. Additionally, a unit with better energy efficiency will cost less to run overall, saving you money on your monthly energy bill. 

Evaporator coils last between 10 and 15 years before they need to be replaced—as long as you stay up-to-date with routine maintenance. This is roughly the same life span as most AC units. So, if you have an older air conditioner and the evaporator coil goes out, it might be more cost-effective to replace the whole unit rather than just the coil.

Indications of an HVAC problem include inconsistent heating or cooling throughout your home, unpredictable temperature changes, or inadequate air flow from vents. Abnormal sounds such as grinding, banging, or hissing, and unpleasant smells like mustiness or burning are also potential warning signs. A rise in energy costs without an increase in usage may also imply decreased efficiency. An HVAC system that frequently cycles on and off or cannot maintain a stable temperature is malfunctioning.

You should clean your air conditioner at least once per year, but you may need to clean your whole HVAC system (including the air ducts) more often. According to the National Air Duct Cleaners Association, you may need to clean them more frequently depending on factors like whether you smoke, have pets, or have allergies.

Some HVAC systems tend to use R410A refrigerant, although if you have an older model it may be using R22. R22 is banned due to its harmful environmental and health impacts, and it is a sign that your AC unit is old enough to consider a replacement and the significant efficiency gains that could come with it.
