HVAC Contractor by PJ Mac HVAC Service & Repair

Expert Heating, Cooling, and Ventilation Solutions for Your Property

5 Highlights on HVAC Contractor Services

HVAC contractors handle complete heating, cooling, and ventilation systems from initial design through final installation and ongoing maintenance. Our certified technicians perform load calculations using Manual J and Manual D standards to properly size furnaces, air conditioners, heat pumps, and ductwork for your specific building requirements. We install split systems, package units, mini-splits, and rooftop units while ensuring compliance with local building codes and permit requirements. Every installation includes refrigerant line sets, copper tubing connections, electrical wiring for thermostats and controls, and complete ductwork fabrication using sheet metal or flex duct materials. Our EPA-certified and NATE-certified team works with all refrigerant types including R-410A and older R-22 systems, providing professional brazing, vacuum pump procedures, and leak detection services that meet manufacturer specifications.

Why Choose Our HVAC Contractor Services

HVAC contractors at PJ Mac bring decades of combined experience to residential and commercial projects. Our master technicians hold current EPA certification for refrigerant handling and NATE certification demonstrating advanced technical knowledge. We employ journeymen, apprentices, and specialized sheet metal workers who fabricate custom ductwork on-site. Every project begins with accurate load calculations to determine proper BTU requirements and tonnage for your space. We don't guess at equipment sizing.

Our estimators provide detailed quotes covering outdoor units, indoor units, air handlers, condensers, evaporators, compressors, and all necessary components. We pull permits and schedule inspections to keep your project compliant. Our installers use torque wrenches, flaring tools, swaging tools, and manifold gauges to ensure leak-free connections. We pressure test refrigerant lines and use nitrogen for purging before charging systems.

You'll receive documentation of SEER ratings, AFUE ratings, HSPF ratings, and EER ratings for your new equipment. We register warranties directly with manufacturers. Our service technicians remain available for callbacks, adjustments, and seasonal maintenance. We stock common parts like capacitors, contactors, relays, transformers, and filters to minimize downtime on repairs.

Signs You Need HVAC Contractor Services

HVAC contractors become necessary when your existing furnace, boiler, or air conditioner reaches 15-20 years of age and repairs exceed replacement costs. Older systems often use R-22 refrigerant that's been phased out, making repairs expensive and difficult. You'll notice declining performance through uneven temperatures, excessive cycling, strange noises from the compressor or blower, and rising energy bills that indicate poor efficiency.

New construction and major renovations require professional HVAC contractors to design and install complete systems. We calculate heating and cooling loads, design trunk lines and branch lines, determine proper CFM requirements, and measure static pressure to balance airflow. DIY installations void manufacturer warranties and often fail inspections. Improper refrigerant charging, incorrect ductwork sizing, and faulty electrical connections create safety hazards and performance problems.

Converting from one system type to another demands contractor expertise. Switching from a furnace and air conditioner to a heat pump requires new refrigerant lines, a reversing valve, defrost board, and modified controls. Adding zoning systems with multiple thermostats, dampers, and zone controllers requires careful planning and professional installation. Smart thermostats and building automation systems need proper integration with existing equipment.

Commercial properties need licensed HVAC contractors for rooftop units, chillers, cooling towers, VAV boxes, economizers, and energy recovery ventilators. These complex systems require engineering calculations, crane services for equipment placement, and coordination with other trades. Building codes mandate specific ventilation rates, makeup air requirements, and exhaust air systems that contractors must design and install correctly.

Ductwork problems like inadequate return air, restricted supply air, disconnected sections, and missing insulation reduce system efficiency by 30% or more. We inspect plenums, boots, elbows, tees, wyes, reducers, and transitions for air leaks. Our sheet metal workers fabricate custom fittings and install proper takeoffs, starting collars, and saddle taps. We add turning vanes in elbows to improve airflow and install fire dampers, smoke dampers, and motorized dampers where codes require them.

Our HVAC Contractor Process

HVAC contractors at PJ Mac start every project with an on-site assessment and load calculation. Our estimator measures your space, evaluates insulation levels, counts windows and doors, and determines sun exposure. We input this data into Manual J software to calculate precise heating and cooling loads. This determines the correct tonnage for air conditioners and heat pumps, BTU input for furnaces and boilers, and required CFM for proper ventilation.

We design ductwork systems using Manual D calculations. Our plans show trunk line sizes, branch line dimensions, register and grille locations, and damper placements. We calculate static pressure to ensure the blower or fan can move adequate air through the system. For existing ductwork, we use a manometer and anemometer to measure actual airflow and identify restrictions.

Installation begins with equipment placement. We position outdoor units on concrete pads with proper clearances for service access and airflow. Indoor units, air handlers, and furnaces get mounted on vibration isolators to reduce noise transmission. Our pipefitters run refrigerant lines using copper tubing, creating flared or brazed connections at the evaporator, condenser, and service valves. We insulate suction lines to prevent condensation and wrap line sets for protection.

Sheet metal workers fabricate and install ductwork, cutting ductboard or flex duct to specified lengths and sealing all joints with mastic. We hang ducts using proper straps and supports. Electricians wire thermostats, connect power to outdoor units, and install safety devices like pressure switches, limit switches, and flame sensors. We pull vacuum on refrigerant lines using a vacuum pump, then charge systems to manufacturer specifications using a refrigerant scale and manifold gauges.

Final steps include system startup, airflow balancing with volume dampers, thermostat calibration, and customer training. We test all safety controls, verify proper combustion on gas furnaces using a combustion analyzer, and check refrigerant superheat and subcooling. You receive documentation, warranty registration, and a maintenance schedule.

Brands We Use

HVAC contractors at PJ Mac install equipment from Carrier, Trane, Lennox, Rheem, Goodman, American Standard, York, Daikin, Mitsubishi Electric, and Bryant. These manufacturers produce reliable furnaces, air conditioners, heat pumps, boilers, and mini-split systems backed by strong warranties. We stock genuine replacement parts including compressors, heat exchangers, evaporator coils, condenser coils, blowers, ECM motors, PSC motors, scroll compressors, reciprocating compressors, expansion valves, and reversing valves.

Our technicians attend factory training for proper installation techniques and warranty compliance. We use Honeywell, Ecobee, and Nest smart thermostats that integrate with building automation systems. For air quality, we install Aprilaire humidifiers and dehumidifiers, HEPA filters, UV lights, and electronic air purifiers. Refrigerant comes from approved suppliers in sealed containers to prevent contamination.

Safety remains our top priority. We test for carbon monoxide leaks, verify proper venting through flues and chimneys, and install flame sensors and pressure switches that shut down equipment if unsafe conditions develop. Our combustion analyzers measure efficiency and detect incomplete burning that produces dangerous gases.
