our story -
a friend in your home
Β
The Owner’s of Donaldson Heating & Air Conditioning, Jamie and Anna Donaldson, have been in HVAC for over 13 years.Β
It all started with cold early mornings in their backyard where Jamie would make ductwork on a their picnic table. As Donaldson Heating & Air Conditioning grew, they realized how much families didn’t know about the impact HVAC can have on their home and their health.Β After one too many times of seeing homeowners being taken advantage of by predatory business practices, low-quality products and not being offered ongoing support, Jamie and Anna knew they wanted to do something about it. Before they knew it,Β True Care was born!
As a local family-owned business, we provide above-and-beyond service, install reliable brands, offer ongoing support, explore and go over all options with you and protect you byΒ sharing the information you need to make informed decisions about your home comfort.Β Long story short, we will always be a friend in your home!
