When temperatures climb, you need an air conditioning contractor who responds fast and works right. PJ MAC HVAC Service & Repair delivers complete cooling solutions for residential and commercial properties throughout the area. Our licensed technicians handle everything from emergency AC repairs to full system installations with the skill and attention your comfort deserves.
Professional air conditioning contractors bring specialized knowledge to every service call. Here's what sets our team apart:
Air conditioning contractors at PJ MAC combine technical expertise with customer-focused service. Our HVAC technicians arrive on time with fully stocked service vehicles ready to diagnose and repair most cooling problems in a single visit. We've built our reputation on honest assessments and transparent pricing—no surprise charges or unnecessary upsells.
Every air conditioning mechanic on our team holds current certifications in refrigerant handling and system installation. We stay current with evolving HVAC technology through ongoing training on heat pumps, ductless mini-splits, variable-speed systems, and smart thermostat integration. Whether you need a simple capacitor replacement or a complete split system installation, we handle the job with the same attention to detail.
Our service guarantees back every repair and installation. We stand behind our workmanship because we use quality parts and follow proper procedures. Property managers and homeowners trust us for reliable cooling solutions that last. When you call PJ MAC, you're working with a local mechanical contractor who treats your property like our own.
Weak airflow from supply vents signals problems with your air handler, blower motor, or ductwork. When rooms stay warm despite the thermostat setting, your HVAC system might have a failing fan motor, clogged air filter, or collapsed duct sections restricting air circulation. An air conditioning technician can test static pressure, inspect ductwork for leaks, and verify proper fan speeds to restore cooling performance throughout your building.
Unusual sounds from your AC unit indicate mechanical problems that need immediate attention. Grinding noises point to worn compressor bearings. Squealing suggests belt issues or motor problems. Clicking sounds during startup might mean a failing contactor or capacitor. Refrigeration mechanics recognize these warning signs and address them before minor issues become expensive failures requiring complete system replacement.
Rising energy bills without increased usage reveal efficiency losses in your cooling system. Refrigerant leaks force compressors to run longer while delivering less cooling. Dirty evaporator coils reduce heat transfer. Thermostat calibration drift causes excessive cycling. A qualified HVAC contractor performs load calculations, tests refrigerant charge, cleans coils, and calibrates controls to restore efficient operation and lower your monthly costs.
Ice formation on refrigerant lines or the evaporator coil means your system can't properly remove heat from indoor air. Low refrigerant charge, restricted airflow from dirty filters, or failing expansion valves create conditions where moisture freezes on cooling components. This ice blocks airflow and prevents proper dehumidification. Service technicians locate the root cause, repair leaks, recharge refrigerant to specifications, and verify proper system operation.
Short cycling where the compressor runs briefly then shuts off damages equipment and wastes energy. Oversized units, refrigerant overcharge, dirty condenser coils, or faulty pressure switches cause this problem. Each startup stresses electrical components and reduces equipment life. Building services contractors measure runtime cycles, test electrical components, clean outdoor units, and adjust refrigerant charge to achieve proper cooling cycles that maintain comfort without excessive wear.

Initial assessment starts when you contact us for service. We ask about symptoms, system age, and recent changes to understand your cooling problem. Our dispatcher schedules a convenient appointment and sends a qualified air conditioning installer to your property with the tools and parts needed for most common repairs.
On-site diagnosis involves thorough testing of your entire HVAC system. Maintenance technicians check thermostat operation, measure supply and return temperatures, test electrical connections, inspect refrigerant lines, and evaluate airflow at registers throughout your space. We use digital gauges to verify refrigerant pressures and specialized tools to detect leaks. This comprehensive inspection identifies all issues affecting your cooling performance.
Repair recommendations come with clear explanations and upfront pricing. We show you the failed components, explain why they stopped working, and outline repair options. You'll receive a detailed estimate before we start any work. Our heating and cooling contractors never pressure you into unnecessary services or equipment replacements.
Professional repairs follow manufacturer procedures and industry best practices. We replace worn parts with quality components, evacuate and recharge refrigerant systems properly, test all safety controls, and verify correct operation before we leave. Every service call includes system performance verification to confirm your air conditioner delivers the cooling capacity and efficiency you need.
Top-rated equipment manufacturers provide the reliability and performance our customers expect. PJ MAC installs and services these trusted brands:
Carrier, Trane, Lennox, Rheem, Goodman, American Standard, York, Daikin, Mitsubishi Electric, and Bryant systems deliver proven cooling performance across residential and commercial applications. Each manufacturer offers different efficiency levels, warranty coverage, and feature sets to match your budget and comfort requirements.
We stock parts for these brands and maintain factory-trained certification on their product lines. Our air conditioning technicians understand the specific requirements for proper installation, refrigerant charging, and system commissioning that each manufacturer requires for warranty coverage.
Safety comes first on every job. We follow EPA regulations for refrigerant handling, use proper electrical safety procedures, and maintain liability insurance to protect your property. Our licensed contractors complete continuing education to stay current with evolving codes and safety standards.

An air conditioning contractor installs, repairs, and maintains cooling systems for homes and businesses. These specialized HVAC technicians diagnose compressor failures, fix refrigerant leaks, replace thermostats, clean coils, test electrical components, and perform complete system installations. They handle everything from simple filter changes to complex ductwork modifications and multi-zone climate control systems.
Contact a cooling contractor immediately when your AC stops working, blows warm air, makes unusual noises, or causes circuit breakers to trip. Schedule service calls for annual maintenance before cooling season starts. Reach out for estimates when your system exceeds 12-15 years old or requires frequent repairs that approach replacement costs.
Licensed HVAC contractors hold EPA certifications for refrigerant handling, carry proper insurance, and understand electrical codes that govern air conditioning work. They diagnose problems accurately using specialized tools and follow manufacturer procedures that protect warranty coverage. Unlicensed work often creates safety hazards, violates building codes, and voids equipment warranties.
Service call fees typically range from $75-150 for diagnosis. Simple repairs like capacitor replacement cost $150-300. Refrigerant recharge runs $200-500 depending on system size and refrigerant type. Complete AC unit replacement ranges from $3,000-8,000 based on capacity, efficiency rating, and installation complexity. Annual maintenance agreements cost $150-300 and include tune-ups, priority scheduling, and repair discounts.
Most HVAC contractors service complete heating and cooling systems. Heat pumps use the same refrigeration cycle as air conditioners but reverse the process for heating. Qualified mechanical contractors diagnose reversing valve problems, test defrost controls, and service both heating and cooling modes. Many also repair gas furnaces, electric heating systems, and boilers as part of comprehensive building services.
Annual tune-ups reduce energy costs by 15-20% through coil cleaning, refrigerant charge verification, and airflow optimization. Preventive maintenance catches small problems before they cause expensive failures. Regular filter changes and inspections extend equipment life by 5-10 years. Service contracts with scheduled maintenance prevent emergency breakdowns during peak cooling season when repair costs increase and technician availability decreases.
