Tandem supports Northampton restaurants, property managers, retail, offices, multifamily buildings, and commercial facilities with plumbing, HVAC, drain, and mechanical service.
Refrigerant Leak Diagnosis for AC, Heat Pumps & Ductless Systems
Refrigerant is the lifeblood of any vapor-compression cooling system. When a leak develops — whether at a flare fitting, brazed joint, Schrader valve, or within the coil itself — system capacity drops, efficiency suffers, and the compressor is put at risk of damage from running in a low-charge condition. Tandem Mechanical's technicians are EPA Section 608 certified and equipped with electronic leak detectors, UV dye inspection equipment, and nitrogen pressure-testing capabilities to locate leaks in split systems, package units, ductless mini-splits, and heat pumps. We document findings clearly and walk you through repair options, code-compliant refrigerant handling, and whether a repair or system replacement makes the most sense given your equipment's age and condition. Proper leak diagnosis is not just about recharging refrigerant — topping off a leaking system without finding the source only delays the problem and may violate EPA regulations. Our goal is to find the root cause, restore proper system operation, and ensure your equipment runs safely and efficiently.
Common Signs You May Need This Service

Hissing or bubbling sounds near the indoor or outdoor unit
Visible oil staining around refrigerant line fittings or coil connections
Frequent short-cycling or compressor shutting down on high-pressure lockout
Humidity levels inside the building feel higher than normal during cooling season

Repair vs. Replacement
Minor leaks at fittings, valve cores, or small brazed joints are generally cost-effective to repair, particularly on systems less than eight to ten years old using currently available refrigerants. However, evaporator or condenser coil leaks caused by formicary corrosion often recur elsewhere in the same coil, and on older R-22 equipment the combined cost of coil replacement and refrigerant can make system replacement the more economical long-term decision. Tandem Mechanical will provide an honest assessment of both paths — including equipment age, refrigerant availability, repair cost relative to system value, and efficiency gains available from a modern replacement — so you can make an informed choice.
HVAC Maintenance
Annual cooling system maintenance should include a check of operating pressures and a visual inspection of all accessible refrigerant circuit components. Catching a developing leak early — before the system loses enough charge to affect performance or trip a low-pressure safety — can prevent compressor damage and avoid a mid-season emergency. If your system uses R-22 (Freon), proactive leak detection is especially important given the limited and costly availability of that refrigerant. Tandem Mechanical recommends that systems showing any symptoms of low charge, or those with a history of repeated recharges, undergo a thorough leak diagnosis rather than a simple top-off.
System Performance
Refrigerant charge is one of the most critical factors in air conditioning system efficiency and capacity. A system operating at even 10–15% below its design charge can lose a disproportionate share of its cooling capacity while the compressor works harder and consumes more energy. Accurate diagnosis — not just a visual check, but quantified pressure and temperature measurements — is the only way to determine whether a system is operating at its designed charge level. Tandem Mechanical technicians use calibrated manifold gauge sets and digital temperature probes to evaluate superheat and subcooling values against manufacturer specifications, ensuring that any recharge is precise rather than approximate.

“I am a first time home buyer and not familiar with the boiler/heating system in my home and was apprehensive about finding a service provider to service my boiler. I def. made the right choice choosing Tandem Mechanical to service my boiler system. I needed my boiler serviced and Josh and Sam arrived today and serviced the boiler in a professional manner. Josh explained everything they were going to do before they started work. They were punctual, professional and went above and beyond. They also addressed questions I had on two other issues, one which could have been a problem later on if not addressed. I was very impressed with these guys and also the lady I spoke with re: setting up the appointment. Thank you TM! Much appreciated.”
