Furnace Installation in San Antonio and a 100% Satisfaction Guarantee* You Can Rely On

Frequently Asked Questions

Here’s a shortcut to some answers we typically give to the people we help with home comfort. 

• Should I replace my furnace and AC system at the same time?

  It’s often less expensive to replace your heating system and AC unit at the same time. Plus, you’ll also enjoy higher energy efficiency year-round. Here’s when you should replace both systems at the same time:

  • Your furnace system and AC unit are more than 15 years old.
  • You want to install a high-efficiency air conditioner soon, which might not be compatible with an older model.
  • You want to improve your energy savings with a smart thermostat, which usually don’t work with older HVAC equipment.
  • Installation is difficult.
  • You don’t want to have to be concerned about HVAC repairs in the next several years.

• What is a Diagnostic Fee?

  A diagnostic fee, also known as a service call fee, is a typical charge levied by HVAC companies when a technician is dispatched to your home to diagnose the root cause of what’s affecting your HVAC system. A diagnostic fee covers the technician’s time, expertise and travel costs associated with determining the underlying cause of the problem. It’s basically a service fee for the technician’s professional inspection to pinpoint the cause of the malfunction.

  It’s like a doctor’s appointment. They have to do some preliminary tests or an examination to help figure out what’s wrong before recommending treatment. Similarly, the technician we send has to inspect your system to decide on the best repair or maintenance steps.
