Reviews for Allegiance Heating & Cooling

Feb 2024

Allegiance was great to work with this week when our furnace shutdown. Their team responded to our call over the weekend sending someone out on Sunday. The service tech Ronnie was professional, knowledgeable and communicated the issues/work that needed to be done. Great to have a trusted and respectable team in our home.

The whole team at Allegiance is top notch. From the office to their technicians. The monthly membership is totally worth the investment.From servicing our AC unit to replacing our furnace when our old one died on the coldest weekend of the year- Allegiance has been there for us.As first time homeowners it can be nerve wracking trying to find companies to trust with key parts of your home- Allegiance has more than earned that trust from us with their quick responses, honest quotes/advice, and fair prices.If you’re trying to find an HVAC company that’s right for you- look no further.

Donnie came by same day we had furnace issues right before that last sub-zero weekend. Control board went bad and he replaced it. The scheduler (forgot her name) was also very helpful.Would recommend.Sidenote: Don’t use Nest thermostats over Ecobee
