Restore Cooling When Your System Fails

Air conditioning repair and service for homes throughout Grand Junction, Colorado.

Your air conditioner stops blowing cold air on a ninety-five-degree afternoon in Grand Junction, and indoor temperatures climb quickly while you wait for help. AC breakdowns during summer are inconvenient and uncomfortable, especially in older systems common throughout Grand Valley neighborhoods where wear on compressors, capacitors, and fan motors leads to sudden failures.

Monarch Heating and Air Conditioning diagnoses and repairs residential air conditioning systems across Grand Junction, addressing issues like weak airflow, refrigerant leaks, electrical failures, and complete system shutdowns. Service calls begin with testing thermostat signals, checking voltage at the condenser, and inspecting refrigerant pressures to identify what caused the breakdown. Repairs are made with the goal of restoring cooling quickly and preventing further damage to connected components.

If your air conditioner is not cooling properly or has stopped running, contact Monarch Heating and Air Conditioning to schedule a repair visit in Grand Junction.

Diagnosing failures before temperatures continue climbing indoors

Your repair visit in Grand Junction starts with checking the most common failure points, including the capacitor that starts the compressor motor, the contactor that sends power to the outdoor unit, and refrigerant levels that drop when small leaks develop over time. Monarch Heating and Air Conditioning uses multimeters and pressure gauges to test electrical components and refrigerant flow, identifying whether the issue is mechanical, electrical, or related to airflow blockages inside the home.

Once the repair is finished, cold air returns to your vents, indoor temperatures drop back to your thermostat setting, and the system runs without short cycling or unusual noises. Addressing failures promptly prevents secondary damage to compressors and blower motors, which can fail completely if the system continues running with underlying issues.

Repairs may include replacing worn capacitors, sealing refrigerant leaks and recharging the system, cleaning clogged condensate drains, or replacing faulty thermostats. Service does not include ductwork modifications or equipment replacement unless the existing system is beyond economical repair. Routine maintenance between cooling seasons reduces the likelihood of mid-summer breakdowns.

What homeowners want to know when cooling stops

When your air conditioner fails during peak summer heat in Grand Junction, you need clear answers about what went wrong, how long repairs will take, and whether the system will hold up for the rest of the season.

What causes an air conditioner to stop cooling?
Common causes include failed capacitors, low refrigerant from leaks, dirty evaporator coils restricting airflow, and electrical failures at the contactor or thermostat. Monarch Heating and Air Conditioning tests each component to identify the specific failure in your Grand Junction home.
How quickly can you restore cooling?
Most repairs are completed during the initial service visit, restoring cooling the same day. Repairs requiring special-order parts may take additional time, but temporary solutions are discussed to keep your home as comfortable as possible.
Why is my air conditioner running but not cooling?
Your system may be low on refrigerant, have a failed compressor, or be dealing with blocked airflow from a clogged filter or frozen evaporator coil. Diagnosis determines which issue is preventing cold air from reaching your vents.
When should I call for air conditioning repair?
Call as soon as you notice weak airflow, warm air from vents, unusual sounds from the outdoor unit, or the system failing to reach your set temperature. Prompt repairs prevent further damage to compressors and other components.
How do I know if my system needs replacement instead of repair?
Age, repair history, and the cost of fixing current issues are all considered. If your system is over fifteen years old and requires expensive compressor or coil replacement, a new installation may be more practical than continued repairs.

Monarch Heating and Air Conditioning provides air conditioning repair throughout the Grand Valley and nearby Western Slope communities, with responsive service during peak summer temperatures. If your system has stopped cooling or is not performing as expected, reach out to schedule a diagnostic visit.

Monarch over the past 2 years we have been with have always responded readily to our service needs. From the individual Sherry that answers the phone and schedules the calls to the technicians has always been a positive experience. We just had a significant issue with one of our AC units. The technician, Nathan Libby, was one of if not the most professional conscientious techs we have encountered. He kept us constantly updated, was so thorough, and had a great personality to go with it all. Extremely satisfied with the job he performed!!! , thank you

The service call on May 23 was very much appreciated. The service technician was on time and very polite and very knowledgeable about what we had scheduled him for and explained what he had accomplished while he was here. I would recommend Monarch HVAC to anyone looking for service on AC & furnace equipment.

Mike B.

I have used Monarch for close to 10 years for all of my HVAC needs. I have come to know their staff and they are exceptional people with integrity, honesty and great work ethic. When they are done with a job, you can count on it being correct and them standing behind their work if something ends up not working the way it should. I would give them 10 stars if I could.

Russell F.

We had a swamp cooler and needed to get an AC system that would work for our house and be energy efficient. We shopped pricing and service from several HVAC contractors. Natalie from Monarch came a did an in depth review of our house and provided pricing and pros and cons for several different systems. She took the time to answer all of our questions and provide a detailed estimate. Once we choose a system, Jon managed the installation and kept us informed of the progress and made sure we were happy with the installation. The project was done on budget and two weeks ahead of the schedule Monarch gave us. It was a pleasure working with Monarch and I would highly recommend them!

Amy B.
