What factors affect the cost of a thermostat repair?

When it comes to repairing your thermostat, there are 4 main factors that will affect the cost, including:

  • The kind of thermostat you have: There are several different kinds of thermostats, and some are more complex than others. The more "complex" your thermostat is, the more your repair will likely cost. For example, repairing a smart thermostat will likely cost more than repairing a non-programmable thermostat.
  • The specific issue you're facing: The cost of your thermostat repair will depend on the specific issue you're facing. For example, if your thermostat is malfunctioning because it needs to be cleaned or has dead batteries, it will be much less expensive than if there's an issue with your thermostat's wiring.
  • Repair or replace: Depending on the specific issue you're facing, your thermostat may need to be replaced rather than repaired. Replacing a thermostat will typically cost more than repairing it due to the cost of the thermostat itself, but it can be the most cost-effective option in the long term. The cost of the replacement can also depend on whether the old wiring is compatible with the new thermostat.
  • The contractor you hire: The price of a thermostat repair can vary based on your technicians’ years of experience and hours of training. It may be cheaper to go with a less reputable company, but the peace of mind that comes with knowing a highly trained, CT-licensed technician is performing your repair makes it worth spending a little extra. At Aiello we only allow the best CT-licensed HVAC technicians in your home.
