Our Guarantee

We’re not satisfied until you are.

We guarantee it.

We prioritize your total satisfaction at Donnelly’s. That’s why we offer not just one, but four industry-leading guarantees. How can we offer multiple guarantees of such breadth and depth? Because as much confidence as we have in our capabilities, we want to instill in you, our customer. 

No matter the size of the job—from routine preventive maintenance to full-system overhauls—you can rest assured that we’ve got you covered.

Comprehensive 100% Satisfaction Guarantee

If you’re not 100% satisfied with our work, the performance of the equipment or components we install, the energy savings we promise, the value we deliver, the convenience we offer or even our people, we’ll immediately do what’s necessary to change that.

Until we achieve your full satisfaction, we don’t consider our job finished. That means we’ll make any modifications needed to complete the work to your standards. This guarantee is so comprehensive, it completely frees you from risk. You simply can’t lose with Donnelly’s!

Customer Experience Guarantee

Call Donnelly’s and you’ll be speaking with a courteous human from the start. That’s right. We answer our phones! Forget voice messages, confusing menu options and missed callbacks. Instead, experience the difference more personal—and available—customer service makes.

Transparent Pricing Guarantee

There’s nothing worse than a final bill riddled with hidden costs and obscure charges. That’s why Donnelly’s will always stand by our fully transparent, upfront pricing. We’ll carefully explain all costs to you before you approve the total price and work begins. And you won’t be blindsided by a higher-than-expected bill!

Cleaner Home Guarantee

Part of earning your respect means showing you and your home respect. For this reason, we’ll always leave your home as clean—or cleaner—than it was when we arrived for service. It’s as simple as that!
