Reliable Air Conditioning Services in St. Paul, MN

There are several common reasons your AC unit may still run but fail to produce cold air, including electrical issues, compressor problems, refrigerant leaks, or a frozen evaporator coil. McQuillan Home Services technicians diagnose the root cause during your service visit and provide a transparent assessment of the issue and repair options before any work begins. Call (651) 292-0124 or schedule online to get a licensed technician to your home.

McQuillan Home Services technicians provide upfront, transparent pricing after diagnosing the issue so you know the full cost before authorizing any work. We charge by the job, not by the hour, and there are no surprise fees for after-hours or weekend emergency calls.

We offer 24/7 emergency AC service with no overtime fees.

AC service costs vary based on the type of work needed. Maintenance and tune-ups are typically a flat fee, while repair costs depend on the specific part that failed and the labor required to access and replace it. New installations are priced based on the system’s SEER2 efficiency rating, cooling capacity measured in tons, and any modifications required to your ductwork or electrical connections. McQuillan Home Services provides upfront pricing after diagnosing the issue so you know the full cost before authorizing any work.

The decision depends on your system’s age, the cost of the repair relative to a new system, and how frequently it has needed service. AC units older than 12 to 15 years with major component failures such as a compressor or evaporator coil are generally better candidates for replacement, especially if they use R-22 refrigerant, which is no longer manufactured. McQuillan Home Services technicians will give you an honest assessment and walk you through both options with clear pricing so you can make an informed decision without pressure.
