The team at Sanders and Johnson knows how important a functioning air conditioner is on a hot Denver day, which is why you can count on us to provide quick, reliable repairs when you need them most. Learn about the common AC issues we help fix, signs it’s time to call a pro for HVAC service, and the types and brands of AC systems we repair.

Common Air Conditioning Problems We See in Denver Homes

Our Denver air conditioning repair service is here to help you address any problem you’re facing with your AC, including:

• Weak or no airflow.
• Water leaks.
• Hazardous refrigerant leaks.
• AC blowing warm air.
• Warm and cool spots throughout the home.
• AC not running at all.
• Short or long-cycling.
• Malfunctioning thermostat.
• Energy inefficiency.

In addition to the standard issues air conditioners face over their lifespan, there are a few Denver-specific considerations to keep in mind. Denver’s high elevation, dry climate, and intense sunlight can place additional strain on home cooling systems over time. This strain may not directly cause AC problems, but it often means Denver systems require more frequent service to operate properly.

Signs You Need AC Repair in Denver, CO

How do you know when it’s time to consider professional air conditioning repair near Denver? There are several key signs to be on the lookout for in your home.

Temperature trouble

One of the most obvious symptoms of an AC malfunction is temperature troubles. Air conditioners may blow warm air due to issues with the evaporator coils or the air filter, sometimes leaving your home warmer than before. You might also find that your home never reaches the temperature you set on the thermostat, even though cool air is coming from the vents. If you’re having any issues with your home temperature, call for AC repair services in Denver.

Airflow issues

If it feels like your AC isn’t putting out air at all, there’s likely an airflow issue somewhere in the system. This could be caused by problems with the outdoor AC compressor or maybe even your air filter. 

Unusual noises or odors

Some quiet humming is normal from an AC, but if you’re hearing loud, unusual noises — particularly screeching, grinding, or squealing — it’s a sign of a problem. The same goes for odors of any kind. If you notice moldy, mildew-y odors or the scent of burning dust, it’s time to have the system inspected and repaired.

Energy inefficiency

An important sign of an AC issue is rising energy bills with no change in your usage. This usually indicates the system is working too hard due to restricted airflow, damaged components, or refrigerant level issues. Contact a Denver air conditioning contractor for repair before you waste any more money on an inefficient unit.

Short-cycling

If your AC is constantly turning off and on without properly cooling your space, there’s likely an issue. Short-cycling may be caused by reduced airflow, low refrigerant levels, or an air conditioner that’s too large for your home. 

Leaks

If you notice water leaks or suspect a coolant leak, have a qualified HVAC technician inspect and repair the system right away. This is especially important for refrigerants, as they can be hazardous to handle without the right tools and training.

We repair a wide range of air conditioner types commonly found in Denver homes.

Central air conditioning

Central air conditioners, which push air throughout the home from a centralized unit via HVAC ducts, are the most common cooling method in the Denver area. Due to the large, interconnected nature of these systems, professional repair helps ensure you’re addressing the root cause of any air conditioning issues.

Packaged systems

Some homes and businesses opt for compact, packaged AC systems to reduce their HVAC footprint while receiving most of the same benefits as larger systems. Fixing these complex systems properly requires in-depth knowledge. Our team can diagnose and repair most issues with your packaged air conditioner system.

Ductless mini-split systems

Ductless air conditioning is an increasingly popular choice for efficient cooling in smaller areas, such as room additions or converted garages. They don’t require HVAC ducts, so they’re quick to install and have fewer parts that could break down in the future. If your ductless mini-split needs repairs, Sanders & Johnson is here to help.  Ductless mini-splits are highly efficient and offer some of the highest SEER ratings around!  We proudly install Mitsubishi, Midea, Fujitsu, and Kaden brands of ductless mini-splits.

Air source heat pumps

More Denver homeowners are switching from central AC to air-source heat pumps due to the amazing Xcel Energy rebates and IRS tax credits currently available to homeowners who purchase this kind of HVAC equipment. Our team can address any issues you’re experiencing with your heat pump, helping you get back to efficient, reliable home cooling.
