Colorado summers are known for sunny days and relatively cool evenings, but a prolonged heat wave can change that pattern quickly. Several days of intense heat can make it difficult for your home to release stored warmth, especially when overnight temperatures remain high.
Your cooling equipment may run longer than usual, upstairs rooms can become uncomfortable, and electrical demand may increase. Preparing before the hottest weather arrives can improve comfort, reduce unnecessary strain on your equipment, and help prevent an inconvenient breakdown.
Start Preparing Before Temperatures Climb
It is much easier to identify a cooling or electrical problem on a normal summer day than during a stretch of extreme heat. Complete a basic home check before the forecast calls for several consecutive days of high temperatures.
- Test your cooling system: Run it early in the day and make sure cool air reaches every important room.
- Check your air filter: Replace a visibly dirty filter with one that matches your system’s requirements.
- Inspect supply vents: Make sure furniture, rugs, curtains, and storage boxes are not blocking airflow.
- Check the thermostat: Confirm the displayed temperature seems accurate and the system responds to adjustments.
- Clear the outdoor unit: Remove leaves, weeds, cottonwood debris, and other loose material around the equipment.
- Listen for changes: Grinding, rattling, buzzing, or unusually loud operation should be investigated before the heat arrives.
A system that already struggles during mild weather is unlikely to perform better under a heavier cooling load. Early attention gives you more time to make a practical decision instead of reacting to an emergency.
Help Your Cooling System Work Efficiently
During a Colorado heat wave, an air conditioner may operate for longer cycles than it does on an average summer day. Longer operation is not automatically a problem, but the system should still produce cool air and maintain a reasonable indoor temperature.
If your air conditioner is not cooling properly, Brothers offers professional cooling services for Denver-area homes. A trained technician can determine whether the problem involves airflow, electrical components, refrigerant, controls, maintenance, or the condition of the equipment.
Check Airflow Before Assuming the Worst
Restricted airflow is one of the most common reasons a cooling system appears to be underperforming. It can also contribute to frozen coils, longer operating cycles, uneven temperatures, and unnecessary wear.
- Install a clean filter in the correct size and airflow direction.
- Keep return-air grilles open and free of dust or household items.
- Open supply vents rather than closing multiple vents in unused rooms.
- Make sure interior doors are not preventing air from returning to the system.
Keep the Outdoor Equipment Clear
Your outdoor unit must release heat collected from inside the house. Plants, grass clippings, leaves, and windblown debris can restrict that process.
Keep the surrounding area clear without opening the cabinet or touching electrical components. If the unit is buzzing, repeatedly shutting off, or failing to start, turn the system off and arrange for professional service.

Use Your Thermostat as a Heat Wave Tool
Your thermostat cannot create additional cooling capacity, but it can help your system operate more predictably. A programmable or smart thermostat can also make it easier to manage temperature changes throughout the day.
A sudden, extreme temperature adjustment will not make an air conditioner cool faster. Instead, choose a reasonable setting and allow the system to work steadily. Homeowners who need better scheduling, more accurate control, or a replacement device can learn about professional thermostat installation and service.
- Avoid extreme setbacks: Letting the house become excessively hot can create a difficult recovery period later.
- Use scheduled adjustments: Make gradual changes based on when your household is home, asleep, or away.
- Keep heat sources away: Lamps, televisions, direct sunlight, and hot appliances can affect thermostat readings.
- Watch for short cycling: Frequent starts and stops may indicate a thermostat, airflow, electrical, or equipment problem.
Do not judge performance only by whether the system reaches an unusually low setting. On an extreme afternoon, the more useful questions are whether the system produces cool air, controls humidity, and keeps the home within a safe and reasonable range.
Reduce the Amount of Heat Entering Your Home
Your cooling equipment has an easier job when less heat enters the building. Simple changes involving windows, doors, lighting, and appliance use can make a noticeable difference during the hottest part of the day.
- Close blinds or curtains on windows receiving direct afternoon sunlight.
- Use ceiling fans in occupied rooms to improve comfort without lowering the thermostat.
- Turn fans off when rooms are empty because fans cool people, not the surrounding air.
- Run ovens, clothes dryers, and dishwashers during cooler morning or evening hours.
- Keep exterior doors closed and limit repeated trips in and out of the house.
- Turn off unnecessary lighting, computers, televisions, and other heat-producing electronics.
Check weatherstripping around exterior doors and look for obvious gaps around windows. These small openings allow hot outdoor air to enter and conditioned air to escape.
Exterior shade is often more effective than trying to manage sunlight after it passes through the glass. Properly placed awnings, shade trees, or exterior coverings can reduce direct solar heat without blocking ventilation around mechanical equipment.
Pay Attention to Upstairs Rooms and Additions
Heat naturally rises, so upper floors often become uncomfortable before the rest of the house. Finished attics, sunrooms, home offices, additions, and converted garages may also lack adequate ductwork or receive limited airflow.
Before purchasing a larger central air conditioner, determine why the affected room is overheating. The cause may involve insulation, sun exposure, air leakage, duct design, equipment sizing, or the way the room is used.
- A home office with computers and monitors may produce more internal heat.
- A west-facing bedroom may receive intense late-afternoon sunlight.
- A remodeled addition may not have enough supply or return airflow.
- A converted garage may have different insulation and ventilation needs.
For certain hard-to-condition areas, a ductless mini-split installation can provide targeted comfort without extending traditional ductwork. Mini-splits can be especially useful for offices, additions, sunrooms, finished basements, garages, and other individual zones.
A ductless system should be properly sized for the room and installed according to the home’s electrical and comfort needs. Bigger is not automatically better, and an oversized unit can create its own comfort and efficiency concerns.
Protect Your Home From Summer Power Surges
Colorado heat waves are often interrupted by afternoon or evening thunderstorms. Lightning, utility disturbances, and sudden changes in electrical demand can send voltage spikes through a home’s electrical system.
Plug-in surge strips can provide a layer of protection for certain electronics, but they do not protect every circuit or permanently connected appliance. A professionally installed whole-house surge protector is installed at the electrical panel to help manage surges before they spread throughout the home.
- Air-conditioning equipment contains sensitive electrical controls.
- Modern appliances frequently contain circuit boards and digital displays.
- Internet equipment and home-office devices can be damaged by voltage spikes.
- Televisions, gaming systems, chargers, and smart-home devices add to the home’s exposure.
A surge protector cannot prevent every type of electrical damage, and it does not replace proper grounding, bonding, or electrical repairs. Whole-house protection is best viewed as one part of a layered electrical safety plan.

Know When Your Cooling System Needs Attention
Longer operating cycles can be normal during extreme weather, but certain symptoms deserve attention. Do not ignore a problem simply because the outdoor temperature is unusually high.
- Warm air from the vents: The system runs, but the air does not feel noticeably cooler than the room.
- Little or no airflow: One or more vents have weak output even after the filter is checked.
- Ice or frost: Ice appears on refrigerant lines, the indoor coil area, or nearby equipment.
- Electrical odors: You notice a burning, smoky, or hot-plastic smell during operation.
- Repeated breaker trips: The cooling circuit will not remain on or trips shortly after startup.
- Unusual sounds: The equipment begins grinding, squealing, banging, buzzing, or rattling.
Turn the equipment off if you smell burning, see smoke, find damaged wiring, or experience repeated breaker trips. Do not repeatedly reset a breaker or open an HVAC electrical compartment.
Professional diagnosis is often less expensive than allowing a small electrical, airflow, or mechanical problem to cause additional damage. Clear explanations and honest options should always be part of the service process.
Create a Household Heat Wave Plan
Home preparation is not limited to mechanical equipment. Families should also decide how they will stay comfortable if the cooling system stops working or a power outage affects the neighborhood.
- Identify the coolest room in the house and keep it shaded during the day.
- Keep drinking water available for family members, guests, and pets.
- Charge phones and portable power banks before severe weather arrives.
- Make a backup plan for children, older adults, pets, and anyone sensitive to heat.
Know where you could go if indoor temperatures become unsafe. Family members with medical concerns should follow guidance from their healthcare professionals regarding heat exposure.
Never rely on an oven, grill, vehicle, or outdoor cooking appliance as a backup power or cooling solution. Generators and fuel-burning equipment must remain outdoors and away from windows, doors, and air intakes.

How early should I prepare my home for a Colorado heat wave?
Begin checking your cooling system as soon as extended high temperatures appear in the forecast. Testing the system several days early gives you time to replace a filter, address airflow problems, or schedule service before demand increases.
Is it normal for my air conditioner to run continuously during extreme heat?
Longer cycles can be normal when outdoor temperatures are unusually high. However, the system should still produce cool air, maintain airflow, and keep the home within a reasonable temperature range.
Should I set my thermostat much lower to cool the house faster?
No. Setting the thermostat much lower does not usually make the air conditioner cool faster. Choose a reasonable setting and allow the system to operate steadily instead of making extreme adjustments.
How often should I check my HVAC filter during a heat wave?
Check the filter before the heat wave and inspect it periodically during heavy use. Replacement frequency depends on the filter, household conditions, pets, indoor air concerns, and the manufacturer’s recommendations.
Can ceiling fans reduce the strain on my air conditioner?
Ceiling fans can help people feel cooler, which may allow for a slightly higher thermostat setting. Fans should be used in occupied rooms and turned off when the room is empty.
Would a ductless mini-split help an upstairs room that stays hot?
It may, particularly when the room lacks adequate ductwork or has unique comfort demands. The room should first be evaluated for insulation, air leakage, sun exposure, airflow, and proper equipment sizing.
Why should I consider whole-house surge protection during summer?
Summer thunderstorms and electrical disturbances can create voltage spikes that affect HVAC equipment, appliances, and electronics. Whole-house surge protection adds a broader layer of protection at the electrical panel, although it cannot prevent every type of damage.
When should I turn off my air conditioner and call for service?
Turn the system off if you smell burning, see smoke, find ice buildup, hear severe mechanical noises, or experience repeated breaker trips. Call (303) 468-2294 for professional assistance rather than repeatedly restarting the equipment.
