Summer Energy Saving Tips for Colorado Homeowners

Summer on the Front Range is stunning and relentless at the same time. The sun that makes this place so livable nine months of the year becomes a legitimate heat management problem in July and August. Most homes are not built to handle it gracefully, and most homeowners are paying for that gap every month without realizing it.

The good news is that a lot of it is fixable for Colorado homeowners, some of it for free, most of it without a contractor. Here is what I have found actually works.

What Does a Home Energy Audit Actually Tell You?

Before I get into the habits, I want to mention something a lot of homeowners skip, Xcel Energy's Home Energy Squad. For a relatively low cost, they send someone to your home for a two-hour visit, conduct a full energy audit, check for air leaks with a blower-door test, inspect insulation and mechanical systems, and give you a customized list of recommendations. Income-qualified customers can get the visit at no cost. Either way, it is genuinely useful because it tells you where your home is actually losing energy, not just where you assume it is. I have seen audits reveal things the homeowner never would have guessed, drafts coming from places that had nothing to do with windows.

Is the Xcel Energy AC Rewards Program Worth It?

Yes. This one surprises people when I tell them about it. Xcel has a free program called AC Rewards where you install a qualifying smart thermostat and let them make small adjustments to your settings during peak demand periods, usually the hottest stretches of summer afternoons when the whole grid is stressed. You can opt out of any event at any time right from your phone. No penalties.

In exchange, you get a $75 instant rebate on your thermostat purchase (up to two devices), a $50 installation incentive when you enroll, and a $25 bill credit every year you stay in the program. If you were going to buy a smart thermostat anyway, this is free money on top of something you were already going to do.

To qualify, you must be a Colorado residential Xcel electric customer with central AC, a WiFi network, and a single-family home. Apartments and condos are not eligible. Visit xcelenergy.com/acrewards for eligible thermostat models and enrollment.

Six Free Things That Actually Make a Difference

None of these require a contractor.

Close south and west-facing blinds between 10am and 4pm. Solar heat gain through glass is real and your AC pays for every bit of it.

Open windows at night. Colorado nights cool down beautifully. Let the house breathe and you may not need the AC until noon.

Run your dishwasher, dryer, and oven after 8pm. Heat-generating appliances during the day make your AC work harder than it needs to.

Flip your ceiling fan to counter-clockwise. It pushes cool air down and makes a room feel several degrees cooler without touching the thermostat.

Change your AC filter before peak season. A clogged filter can reduce efficiency by 15 percent and most people forget until something sounds wrong.

Unplug what you are not using. Chargers, TVs on standby, older appliances. Phantom loads add up across a summer.

The Longer Game: Plant for Shade and for Life

I have been slowly replacing parts of my yard with native plants and trees, and the energy angle is only part of why. Strategic shade on the south and west sides of a home can reduce cooling costs by up to 25 percent over time. But the bigger reason I do it is what those trees support.

My favorite is the oak. Not because it is the flashiest tree, but because it might be the most generous one. Oaks support more species of insects and birds than almost any other tree in North America. We are talking hundreds of species of caterpillars, which are the backbone of the food web for nesting birds, pollinators, beetles, and everything up the chain. When I plant an oak, I am not just adding shade. I am adding habitat. And on the Front Range, where development pressure on native ecosystems is real, that matters.

If you can plant one tree near the west or south side of your home, make it an oak. Your utility bill and about 500 other species will thank you.

For Front Range native plant resources, Colorado State University Extension is a great starting point. Local native plant nurseries can help you match the right species to your soil and sun exposure.

Why Energy Efficiency Shows Up in Real Estate

I talk about this with buyers and sellers constantly. Homes that have been audited, upgraded, and thoughtfully maintained sell better, not just because the numbers look good, but because buyers feel it. A well-insulated, efficient home is quieter, more comfortable, and less expensive to run month to month.

If you are thinking about selling in the next year or two, a Home Energy Squad visit and a few targeted upgrades could be one of the better investments you make before you list. And if you are staying put, the same logic applies. A home that costs less to cool in summer is simply a better place to live.
