Hammond Heating & Air has been keeping south Denver homes comfortable since 1987. Same family. Same shop.
AC units work harder at altitude. We size and tune systems specifically for the Front Range—hot dry summers, cold winters, the snap from 95° to 50° in twelve hours.
Most Denver homes still run natural gas furnaces. We service every brand, install Trane and Lennox primarily, and pull permits ourselves. Heat pumps where they make sense.
Spring AC tune-up and fall furnace tune-up. Priority scheduling, no overtime charges, and 15% off any repair you do need. The plan pays for itself the first time something acts up.
Denver is dry. The Front Range gets wildfire smoke. We install whole-house humidifiers and HEPA-grade filtration that handles both—without the homeowner needing to think about it.
We don't take on big commercial—we leave that to the big firms. But we do serve small commercial buildings in our service area. Dave Hammond runs that side of the shop.
Call the shop, tell us what's wrong, and we'll tell you whether it's a repair, a replacement, or just a tune-up. No pressure, no upsell—that's the whole point.
Call (303) 555-HVAC →Most HVAC companies sell on price or fear. We sell on the promise that we'll be the only call you ever have to make.
No surprises. We explain the problem, lay out your options, and price each one up front—so you can choose what's right. The number we quote is the number you pay.
Our techs are paid hourly, not on commission. They have zero incentive to push what you don't need. If your system has another five years in it, we tell you so.
When you call us back, we send the tech who knows your system. Our average customer has worked with us for seventeen years. That's not an accident.
Three generations of Hammonds have run this shop since 1987. Five of us work here today—and one founder still drops by twice a week to drink coffee and inspect the trucks.
Founded Hammond in 1987. Semi-retired now, he still comes by the shop a couple of days a week to check in on the team and the trucks.
Bill's son. He studied business at Colorado State and spent a few years in finance before returning to lead the family business in 2015.
A CPA who oversees the shop's operations—scheduling, billing, and the systems that keep everything running on time.
A NATE-certified master technician. He leads the field team and trains every new technician the shop hires.
Leads Hammond's light commercial division, which he joined in 2018 after eight years in commercial HVAC.
A real Hammond dispatcher answers—not a call center. We'll set a time that works for your day, not ours.
Your tech calls when he's twenty minutes out. He arrives in a marked Hammond truck. You'll know him by name.
He explains what's wrong in plain language—no jargon, no scare tactics—and walks you through your options with up-front pricing on each.
No pressure, no "limited time" gimmicks. Most repairs are done same-day. We tell you the timing up front.
Two days later, a real person calls to make sure it's running right. If anything's off, we come back at no charge.
Hammond serves the south Denver suburbs and the southern edge of Aurora. We don't dispatch trucks ninety minutes from the shop—we'd rather do the work close to home and be there when our customers need us.
Most of our service area sits within forty minutes of the shop on Mineral Avenue. If your neighborhood is on the list, you're in.
"They installed my parents' system in 1998. Came out to mine in 2014. Now my daughter's place in 2024. Three generations of one family using three generations of Hammonds. Tells you everything."
"The tech who came out was the same guy who fixed our AC last spring. He remembered our dog. He remembered which room runs cold in winter. That's not customer service—that's neighbors."
"We got three quotes for a new furnace. Hammond was in the middle on price. We picked them because Tom himself walked us through what we needed instead of upselling us to a system three sizes too big."
Hammond runs a real twenty-four hour emergency line. The person who picks up is a Hammond. No call center, no overseas dispatch.
We answer the phone—and we'll get a tech to your house tonight if it's a real emergency.
📞Whether it's a system check, a repair, or a full replacement, we make it easy. Schedule online in under two minutes, or call us and a real Hammond will pick up.
