What Sets Us Apart
Heat pumps aren't a commodity purchase, and neither is who installs one. Here's what makes us the option worth calling.
Authorized Lennox dealer.
Lennox only extends dealer status to companies it trains and certifies directly, and we're one of them, along with being authorized for Carrier and Green equipment. That backing goes into every heat pump recommendation we make.
Family-owned since 2009.
We've run this as a family business in Chicago and its suburbs for more than fifteen years now. Call us and you'll reach our team directly, not a dispatch center.
EPA certified technicians.
Every technician on staff carries EPA certification, which matters most for the refrigerant work heat pumps require.

Why an Authorized Lennox dealer Matters
Not every HVAC company can call itself an authorized Lennox dealer, since Lennox only extends that status to companies it has trained and vetted directly. That backing carries over to every heat pump we install, which means your warranty stays intact and the parts going into your system are genuine, not aftermarket substitutes.

Heat Pump Repair, Cost & Maintenance FAQ
Is D's Air & Heating an authorized Lennox dealer?
Yes. Lennox certifies dealers directly rather than letting anyone claim the title, and we hold that certification, along with authorization for Carrier and Green equipment. We've been doing this work in Chicago and the surrounding suburbs since 2009. See what our Lennox dealer status means for you.
Do heat pumps actually work in Chicago winters?
Yes, a properly sized modern heat pump can keep a Chicago home warm through winter, and many homeowners pair one with a backup system for the coldest stretches. The right setup depends on your home and your comfort priorities. Book a free estimate and we'll help you figure out what fits.
Why is my heat pump covered in ice or frost?
A light layer of frost during a defrost cycle is normal, but a heavy buildup of ice usually points to low refrigerant, a fan problem, or a stuck defrost control. Ice that isn't melting off on its own is worth a call. Book a heat pump repair and we'll take a look.
Why won't my heat pump switch between heating and cooling?
This is often a thermostat setting issue, but it can also mean a reversing valve isn't working correctly. A stuck reversing valve won't fix itself and typically gets worse over time. Schedule a repair so we can diagnose it properly.
Why does my heat pump run constantly without shutting off?
A heat pump that never cycles off may be undersized for the home, low on refrigerant, or working against a thermostat set too aggressively. It's also a common sign of rising energy bills before anything else looks wrong. Book a heat pump service visit to have it checked.
How much does heat pump installation cost in Chicago?
Cost depends on the size of the heat pump, its efficiency rating, and whether you need a backup heat source for winter, so it varies from home to home. We'll give you a free, itemized estimate before any work begins, and financing is available if you qualify. Book your free estimate.
What should I do if my heat pump stops working?
Call us or book online right away. A heat pump that won't heat or cool is treated as an emergency, and our EPA certified technicians will diagnose the issue and recommend the most cost-effective fix.
