How quickly can you respond to repair calls?

We prioritize repair scheduling based on urgency and attempt to provide same-day or next-day service for most situations. During extreme weather when call volume peaks, response times may extend to 2-3 days for non-emergency situations. Customers on our maintenance plans receive priority scheduling advantages.

What are typical package unit repair costs?

Repair costs vary dramatically based on the specific problem, required parts, labor complexity, and equipment age. Simple repairs cost significantly less than major component replacements. 2B COOL Services provides clear upfront pricing before beginning any work. Contact us for a detailed quote specific to your situation.

Do you repair all brands of package units?

Yes, our 40 years of experience covers all major package unit brands including Armstrong, Samsung, Carrier, Trane, Lennox, Goodman, Rheem, York, Coleman, and others. While we specialize in Armstrong equipment as a ProTeam Dealer, we're fully equipped to diagnose and repair any brand professionally.

Why is my package unit freezing up?

Package units freeze for several reasons including restricted airflow from dirty filters or blocked returns, low refrigerant charge from leaks, failed blower motors or capacitors, stuck-closed expansion valves, or operation in excessively low outdoor temperatures. Ice formation requires immediate attention because continued operation can damage compressors.

Should I repair or replace my old package unit?

This depends on equipment age, repair costs, overall condition, and your budget. Generally, if repair costs exceed 50% of replacement cost and equipment is over 12-15 years old, replacement makes better sense. 2B COOL Services provides honest guidance specific to your situation based on 40 years of experience.

System Won't Start or Power On

When package units fail to start, the problem typically involves electrical components, safety switches, or control systems. Common causes include failed capacitors that prevent motors from starting, tripped circuit breakers or blown fuses, defective control boards that don't send startup signals, faulty contactors that won't energize, thermostat wiring problems or incorrect settings, and tripped safety switches from previous system problems.

Our diagnostic approach begins with verifying electrical supply to the unit, testing all safety switches and their operation, checking capacitor condition and microfarad ratings, measuring control voltages and signals, inspecting all electrical connections for corrosion or looseness, and testing thermostat operation and wiring integrity. This systematic process identifies the actual cause rather than guessing at solutions.

Electrical problems can be intermittent and temperature-dependent, making diagnosis challenging without proper testing equipment and experience. Our technicians carry comprehensive electrical testing tools and understand how package unit control systems operate, enabling accurate diagnosis even for complex electrical failures.

Runs But Produces No Cooling

Package units that run but don't cool properly often have refrigeration system problems, airflow restrictions, or failed cooling components. Common issues include refrigerant leaks that reduce system capacity, failed compressors that can't circulate refrigerant, frozen evaporator coils from airflow or refrigerant problems, clogged or restricted expansion devices, dirty condenser coils that prevent heat rejection, and failed cooling contactors or relays.

Our cooling system diagnosis includes measuring refrigerant pressures and temperatures, testing compressor operation and amperage draw, checking airflow across both indoor and outdoor coils, inspecting coils for cleanliness and damage, verifying expansion device operation, and testing all cooling-related electrical components. This comprehensive approach identifies root causes rather than symptoms.

Refrigerant problems require specialized equipment and EPA certification to diagnose and repair properly. Our technicians are fully certified and equipped to handle all refrigerant-related repairs, from leak detection and repair to proper system evacuation and recharging procedures that restore optimal performance.

Inadequate Heating Performance

Package units with heating problems may have gas heating components, electric heat strips, or heat pump systems that require different diagnostic approaches. Gas heating issues include ignition system failures, gas valve problems, heat exchanger concerns, or venting problems. Electric heating problems typically involve failed heat strips, sequencer failures, or electrical supply issues. Heat pump heating problems include reversing valve failures, defrost control issues, or auxiliary heat problems.

Our heating system diagnosis varies by heating type but includes testing ignition systems and gas supply (gas units), measuring heat strip amperage and operation (electric units), checking reversing valve operation and defrost controls (heat pumps), inspecting heat exchangers for damage or restrictions, verifying proper combustion and venting (gas units), and testing all heating-related safety controls and their operation.

Heating system problems can create safety concerns, especially with gas-fired equipment. Our technicians are trained in proper safety procedures and carry combustion analysis equipment to ensure safe, efficient operation after repairs. We never compromise on safety when servicing heating equipment.

Short Cycling On and Off

Package units that cycle on and off frequently waste energy, provide poor comfort, and experience accelerated wear. Common causes include oversized equipment that satisfies thermostat settings too quickly, thermostat problems including incorrect settings or faulty sensors, refrigerant charge problems that cause pressure switch cycling, dirty coils that cause overheating and safety shutdowns, failed pressure switches or other safety controls, and electrical problems that cause intermittent operation.

Our cycling problem diagnosis includes monitoring system operation through complete cycles, measuring run times and cycle frequency, testing thermostat operation and calibration, checking refrigerant pressures during operation, inspecting all safety switches and their settings, and verifying proper electrical supply and connections. This detailed analysis identifies why the system cycles improperly.

Some cycling problems result from improper system sizing or installation issues that require different solutions than component repairs. Our experience helps distinguish between repairable problems and situations that might require system modifications or replacement for optimal performance.

Excessive Noise During Operation

Unusual noises from package units often indicate mechanical problems that require prompt attention to prevent major failures. Common noise sources include failing motor bearings that create grinding or squealing sounds, loose panels or components that rattle during operation, compressor problems that cause knocking or grinding noises, debris in blower assemblies that creates scraping sounds, and refrigerant flow problems that cause hissing or bubbling noises.

Our noise diagnosis involves listening to the system during operation to identify noise sources, inspecting all mechanical components for wear or damage, checking motor bearings and lubrication, tightening loose panels and fasteners, removing debris from blower assemblies, and testing compressor operation for internal problems. Different noises indicate different problems, and our experience helps identify issues accurately.

Some noises indicate imminent component failure that could cause secondary damage if not addressed promptly. We prioritize noise-related repairs that could prevent more expensive failures and help customers understand which noises require immediate attention versus those that can be monitored.
