Heating and Air Conditioning FAQ
Do you offer emergency heating and air conditioning service?
Yes. We're available 24/7 across McKinney and Collin County. Call after hours, and a real person picks up and gets a technician headed your way.
Should I repair or replace my heating system?
It comes down to the system's age and the cost of the fix. Under 10 years old with a minor issue usually means repair; older or breaking down often means replacement pays off. We break it down further in our guide on whether to repair or replace your heating system, and we'll give you a straight answer in person.
Why does my heater smell like it's burning?
Usually, it's just dust burning off the first time you run the heat for the season, and it fades within a few minutes. If it keeps up or smells electrical, shut it off and call us. Here's a full rundown of what a burning smell from your heater can mean.
How can I lower my air conditioning bills?
Regular maintenance, a clean filter, and a smart thermostat make the biggest difference. We put together some practical tips on how to save money on air conditioning.
What's the best thermostat for my home?
A good Wi-Fi thermostat pays for itself in comfort and savings, and the right one depends on your system. We compared options in our post on the best Wi-Fi thermostat for your home, and we can install it during any service visit.
What brands do you install and service?
We work on every make and model. As a Trane Comfort Specialist and Mitsubishi-authorized dealer, we're factory-trained on those specifically, and we won't turn down a job over the brand.
