Common Air Conditioning Failures We Resolve
Our technicians diagnose and repair a wide range of air conditioner problems to keep your home cool and refreshed all summer long.
Warm Air From Vents
System blowing unconditioned air due to low refrigerant levels, dirty coils, or failed compressor capacitors.
Frozen Evaporator Coils
Ice accumulation along indoor refrigerant lines caused by restricted system airflow or dirty air filters.
Frequent Short-Cycling
The outdoor condenser turning on and off rapidly every few minutes without cooling your home evenly.
Water Leaking Indoors
Clogged condensate drain lines or cracked drain pans causing water pooling around your indoor furnace or air handler.

Warning Signs That Demand Professional AC Service
Vents blowing lukewarm air while the thermostat is set to cool.
Loud buzzing, screeching, or clicking noises from the outdoor unit.
Sudden, unexpected spikes in summer electric utility bills.
Puddles of water forming near the indoor mechanical unit.
Persistent high indoor humidity levels despite continuous cooling.
Weak or restricted airflow coming from supply air registers.
Constant system cycling without reaching the set temperature.
Deciding Between Air Conditioning Repair and Replacement
Choosing whether to repair your air conditioner or invest in a new system depends on equipment age, repair history, and overall energy performance. If your cooling system is under ten years old and experiencing a minor mechanical fault, a targeted repair is generally the most economical choice. However, if your air conditioner requires constant maintenance, relies on obsolete refrigerant, or causes rapidly rising electric bills, replacing it with a high-efficiency model offers greater long-term savings. Qualifying instant Xcel Energy rebates can also significantly offset your initial replacement investment.
Frequently Asked Questions About AC Repair and Service
Why is my air conditioner running but not cooling the house?
An air conditioner that runs without cooling is usually suffering from a dirty air filter blocking airflow, a clogged outdoor condenser coil, low refrigerant levels from a leak, or a failing compressor capacitor. Checking and changing a clogged air filter is a good first step before scheduling professional diagnostics.
What causes an air conditioner evaporator coil to freeze up?
Evaporator coils freeze when airflow across the coil is severely restricted by dirty filters, blocked vents, or a failing blower motor. Low refrigerant levels can also drop coil temperatures below freezing, causing moisture in the air to turn into ice along the coil fins and copper lines.
How often should my air conditioner be professionally serviced?
Your air conditioner should be professionally serviced once a year, ideally in early spring before hot summer weather begins. Regular tune-ups clean dirt from condenser coils, verify proper refrigerant charge, inspect electrical contactors, and ensure energy-efficient operation during peak cooling months.
How long does a typical AC repair visit take?
Most air conditioning repair visits take between one and two hours to complete, depending on the complexity of the diagnostic testing and component replacement required. Our technicians carry common replacement parts to resolve most mechanical or electrical faults during the initial visit.
Are utility rebates available for air conditioner repairs or upgrades?
While routine maintenance and repairs generally do not qualify, upgrading an older, inefficient air conditioner to a new high-efficiency model makes you eligible for instant Xcel Energy rebates. We process qualifying instant rebate savings directly on your replacement invoice to lower your upfront costs.
