It starts with Tammy who pleasantly works hard to ensure that your needs are are well addressed. Geoff is the technician that has provided service in our home. We suffered through a number of unexceptional service providers until we found Geoff and we have been using him exclusively for several years now, most recently for our annual HVAC service plus a humidifier replacement. If you want to shop for the cheapest, don't call Tinman but also be prepared to live with the results. If you want good value, and to get the best bang for your buck, then call Geoff and you'll get predictable results, a FAIR price, and solid advice.
