The deposit is fully refundable if we do not go forward with the installation. There are some homes, however rarely we can’t install standard units.
We prefer the deposit only in the unlikely event we do need to refund its simpler for us and you the customer.
Additional fees are rare but this is why we do a site visit so there are no surprises when we do the install. Each home can be a bit different.
If you need a thermostat, humidifier, or anything else, the person that comes out to do the site visit and measure up, can make recommendations for a more comfortable system.
