Colorado summers hit hard. Your air conditioner works overtime when temperatures soar past 90 degrees in Denver. Nothing ruins a sweltering afternoon like your A/C shutting down because it keeps tripping the circuit breaker.
You reset the breaker once. It trips again. You reset it a second time. Same result.
This cycle signals serious electrical problems that demand immediate attention. The issue isn’t with your A/C unit itself—it’s with the electrical system powering it. Your A/C tripping the breaker repeatedly puts your home at risk and leaves you sweating through another scorching Colorado heat wave.
What Causes Your A/C to Trip Circuit Breakers
Overloaded Electrical Circuit
Your air conditioner draws massive power when it starts up. Central A/C units pull 15-20 amps during normal operation. Window units need 8-15 amps. Add other appliances to the same circuit and you create an overload situation.
Circuit breakers trip to protect your wiring from overheating. When electrical demand exceeds the circuit’s capacity, the breaker shuts off power automatically.
Signs of circuit overload include:
- Multiple appliances losing power simultaneously
- Lights dimming when the A/C starts
- Warm outlet covers or switch plates
- Burning smells near electrical panels
Short Circuit in A/C Wiring
Short circuits occur when hot wires touch neutral wires or ground wires inside your air conditioning system. This creates an immediate surge of electricity that trips breakers instantly.
A/C short circuits develop from:
- Damaged wiring insulation
- Loose electrical connections
- Water damage to electrical components
- Rodent damage to wires
- Age-related wire deterioration
Short circuits are dangerous. They generate heat and sparks that can start electrical fires.
Ground Fault Issues
Ground faults happen when electricity flows through unintended paths. Your A/C unit sits outdoors where moisture creates ideal conditions for ground faults.
Common ground fault causes:
- Water infiltration in electrical connections
- Damaged outdoor wiring
- Corroded electrical components
- Faulty GFCI protection
Ground fault circuit interrupters (GFCIs) detect these problems and shut off power to prevent electrocution.
Electrical Component Failures
Electrical components within your A/C system can fail and draw excessive current. These failures create electrical faults that trip circuit breakers for protection.
Electrical component issues show these symptoms:
- A/C struggles to start
- Humming sounds from outdoor unit
- Intermittent power loss to the unit
- Higher electricity bills
Electrical components typically last 10-15 years. Colorado’s extreme temperature swings accelerate electrical component failure. While HVAC technicians handle the A/C components themselves, licensed electricians diagnose and repair the electrical supply issues that cause these problems.
Undersized Electrical Wiring
Older homes often have undersized wiring that cannot handle modern A/C systems. Wire gauge determines current capacity. Undersized wires overheat under high electrical loads.
14-gauge wire handles 15 amps maximum. 12-gauge wire supports 20 amps. Central air conditioning systems often require 30-50 amp circuits with 10-gauge or larger wire.
Signs of undersized wiring:
- Frequent breaker trips
- Warm electrical panels
- Flickering lights during A/C operation
- Reduced cooling performance
Why Repeatedly Resetting Breakers Creates Danger
Breakers trip for protection. Resetting tripped breakers without fixing underlying problems puts your family at serious risk.
Fire Hazards
Electrical fires start when wiring overheats. Bypassing breaker protection by constant resetting allows dangerous heat buildup in walls and electrical panels.
The National Fire Protection Association reports that electrical problems cause 13% of home fires annually. Faulty wiring kills more than 400 Americans each year.
Equipment Damage
Your air conditioner suffers internal damage when operating on compromised electrical systems. However, the root problem lies in the electrical supply, not the A/C unit itself. Poor electrical conditions cause A/C components to fail prematurely.
Electrical problems that damage A/C equipment cost thousands in repairs. Professional electrical system repairs cost hundreds and prevent expensive equipment replacement.
Code Violations
Colorado electrical codes require proper circuit sizing for air conditioning equipment. Operating A/C systems on inadequate electrical circuits violates local building codes.
Code violations complicate insurance claims and create liability issues during home sales.
When to Call a Licensed Electrician
Some electrical problems require immediate professional intervention. Never attempt DIY repairs on high-voltage electrical systems that power A/C equipment.
The electrical issues causing your A/C to trip breakers require licensed electrician expertise. HVAC technicians handle the air conditioning equipment itself, but electricians diagnose and repair the electrical supply problems.
Emergency Situations
Call ElectriCall at 720-879-2253 immediately if you experience:
- Burning smells from electrical panels

Colorado-Specific A/C Electrical Challenges
Altitude Effects on Electrical Equipment
Denver sits 5,280 feet above sea level. High altitude affects electrical equipment performance. Thinner air provides less cooling for electrical components, causing overheating and premature failure.
A/C electrical systems work harder at altitude. Electrical components rated for sea level may underperform in Colorado’s thin air, creating electrical load issues that trip breakers.
Temperature Extremes
Colorado experiences dramatic temperature swings. Summer days reach 100+ degrees while nights drop to 60 degrees. These extremes stress electrical connections and components.
Metal wiring expands and contracts with temperature changes. Repeated thermal cycling loosens connections and creates resistance hot spots.
Seasonal Electrical Demands
Colorado’s intense summer heat creates peak electrical demands. Air conditioners run continuously during heat waves, stressing electrical systems beyond their design limits. Older electrical systems struggle under sustained high electrical loads.
Peak electrical demand periods reveal electrical system weaknesses that remain hidden during mild weather.
Professional Electrical Solutions for A/C Power Issues
Circuit Capacity Upgrades
Modern central air systems require dedicated 240-volt circuits. Upgrading electrical panels and installing proper circuits eliminates overload problems permanently.
Dedicated A/C circuits provide:
- Adequate current capacity
- Stable voltage supply
- Reduced interference from other appliances
- Code compliance
- Enhanced safety
Electrical Panel Modernization
Older electrical panels lack capacity for modern A/C systems. Panel upgrades provide additional circuit spaces and increased amperage capacity.
Modern panels include:
- Arc fault circuit interrupters (AFCIs)
- Ground fault circuit interrupters (GFCIs)
- Surge protection devices
- Smart monitoring capabilities
Wiring Infrastructure Improvements
Undersized wiring creates bottlenecks in electrical systems. Professional rewiring eliminates voltage drops and overheating issues.
Proper A/C wiring includes:
- Correctly sized conductors
- Proper grounding systems
- Weather-resistant connections
- Code-compliant installation methods
Arvada’s Rich History and Modern Electrical Needs
Arvada, founded in 1870, began as a farming community along Clear Creek. The city’s name honors Hiram Arvada Haskin, an early homesteader. Historic Olde Town Arvada preserves the community’s agricultural heritage while embracing modern residential development.
Today’s Arvada homeowners face unique electrical challenges. Many homes date to the 1950s-1970s when air conditioning was uncommon. Original electrical systems lack capacity for modern A/C power demands.
The electrical infrastructure in these older homes cannot support today’s high-efficiency A/C systems without upgrades.
The Ralston Creek Trail and Clear Creek Trail provide recreational opportunities for Arvada residents. These greenways follow historic waterways that powered early mills and attracted settlers to the area.
Arvada’s location between the Rocky Mountain foothills and Denver’s urban core creates microclimates that challenge electrical systems powering HVAC equipment. Elevation changes within the city affect electrical loads and power demands.
