Thermostat Repair & Replacement Done Right
A bad thermostat looks a lot like a bad HVAC system. Ricotta diagnoses the real cause and installs the right thermostat for your equipment.
Smart Thermostats That Actually Work With Your System
A surprising number of HVAC service calls turn out to be thermostat problems — bad batteries, miswired terminals, dead screens, or a unit that simply isn't compatible with the system it's controlling.
Ricotta installs and configures thermostats from major brands, including smart and Wi-Fi connected models. If you've installed one yourself and the system isn't behaving, we can sort it out.
- Smart and programmable thermostat installation
