However, Fieldpiece meters tailor their features sets directly to routine testing HVAC techs conduct. Let’s examine additional factors like durability, ease of use, pricing, and warranties where choices become less obvious. Durability Comparison In regards to physical construction and weatherproof/drop standards, both brands rate closely for models targeted at HVAC field work. The mid-tier Fluke 116, high-end 179, and leading Fieldpiece HS36 all meet 6.5+ foot drop tests and at least an IP54 rating against dust and water ingress per IEC inspection standards. As a result, expect reliable mechanical performance for years of accidental drops into truck beds or on rough commercial job sites. Slight advantages do exist however: The Fluke 179 flagship earned an IP67 rating meaning it’s fully dust tight and can withstand 30 minutes immersions in water up to 1 meter deep. The HS36 is only IP54 rated. Fieldpiece test leads feel slightly less rugged - being thinner and more prone to kinking from twisting compared to durable Fluke test leads. Replacement leads are readily available however. For the vast majority of heating and cooling service calls under typical conditions, both brands stand evenly when it comes to physical construction. Fluke simply provides extra assurance for max weatherproofing and outright abuse. Also Read: Differences Between Fieldpiece SC480 And SC680 Multimeters. Ease of Use Comparison Multimeters balance wide measurement capabilities with ease of operation via their user interfaces. When evaluating Fluke vs Fieldpiece models for HVAC applications, preferences emerge: For broad varied usage across electronics troubleshooting fields, most technicians would rate Fluke meters as easier to use. Their larger displays with clear auto-ranging readouts, smooth rotary dials, and standard labeling simplify interpretation. The pocket-sized 116 for example excels here. For users concentrated almost exclusively on HVAC service, Fieldpiece meters provide streamlined operation thanks to: Dedicated buttons for activating Superheat, Subcooling, and other pre-configured modes essentail to heating/cooling work. Simplified button clusters with built-in ranges as opposed to complex rotary dial selection on Fluke units. So technicians crossing over between various specialties may find Fluke units work better out of box. But for those squarely focused on HVAC, Fieldpiece meters offer efficient ergonomics and measurement activation. Pricing & Value Comparison When making any buying decision, cost invariably factors into the calculation. Given their reputation for high-end accuracy and ruggedness earned across industries, Fluke units universally cost more than Fieldpiece models with similar functionality. As prime examples: The flagship Fluke 179 retails around $450, while the Fieldpiece HS36 costs roughly $150 - a $300 premium for the 179. The compact 116 Fluke sells for approximately $190 vs $90 for the budget-oriented Fieldpiece HS33. There’s no question you pay a sizeable mark-up for proven Fluke quality. However, the adage holds true: you get what you pay for. While Fieldpiece meters offer respectable value matching functionality to lower price tags, Fluke models deliver greater measurement range/accuracy, advanced features, reliability, warranties, and long working lifespans worth price premiums to serious technicians. Paying $300+ more for a 179 over an HS36 buys peace of mind and high-end capability difficult to replicate at consumer price points. For homeowners, entry-level HVAC mechanics, or techs on tight budgets, Fieldpiece meters offer your most affordable path to essential voltage/current/Superheat testing in compact form factors. Just expect to compromise certain accuracy, power user features, and long term robustness compared to a 179. Warranty Comparison When gauging expected working lifespan before replacement, warranty coverage provides useful insight into how confidently the manufacturer stand’s behind their reliability claims. Here as well, Fluke outpaces Fieldpiece. While Fieldpiece meters as a whole perform respectably for years when following operating limits, their standard warranty only covers manufacturing defects for 1 year after purchase. Extensions to 2 and 3 years are offered with product registration. In contrast, Fluke’s industry-best Lifetime Warranty guarantees repair/replacement for ANY failures outside excessive abuse across all 177/179 calibration specifications. Demonstrating confidence even small resin components and switches won’t degrade for decades, this remains uncommon for compact handheld electronics exposed to field conditions. For budget-focused buyers less expectant of 10+ years reliable operation, Fieldpiece’s standard 1 years coverage should suffice though. Pay the Fluke premium if seeking a meter to use continuously across your entire career. Also Read: Comparison of Fluke 101 And Klein MM400 Multimeters. Closing Remarks Given the detailed functionality and specification comparison between popular Fluke digital multimeters and Fieldpiece alternatives tailored for HVAC applications, which brand wins out as most ideal for heating/cooling technicians? For Apprentice and Home HVAC Owners If launching an HVAC career or requiring basic system troubleshooting as a homeowner, I recommend the Fieldpiece HS33 as the best value multimeter. Priced below $100, it includes fundamental measurement modes like voltage, Resistance, Continuity, Superheat calculations, and CO monitoring in a compact, intuitive format. Downsides of lower accuracy, durability, and 1 year warranty are minimized if used gently across residential maintenance needs - not subjected daily to commercial equipment abuse. For Residential and Light Commercial HVAC Technicians Technicians earning a living primarily across residential service calls, light commercial sites, or basic HVAC installations should strongly consider the Fieldpiece HS36 stick multimeter for $150. With True RMS, superheat/subcool modes, durable IP54 rated body, and sensible button layout, the HS36 simplifies daily tasks like diagnosing bad compressor windings or plotting expansion valve performance. DC voltage, microamp, and continuity cover standard circuit debugging as well. Unless you require advanced measurement ranges or cross-disciplinary versatility, the HS36 delivers capable performance and special HVAC functions that speed up work compared to generic Fluke models in the sub $200 range. For Commercial/Industrial HVAC Technicians For licensed technicians servicing complex commercial equipment, large-scale HVAC systems across hospitals, industrial facilities, etc - the Fluke 179 truly earns its place as the industry gold standard multimeter for HVAC. Unmatched accuracy and advanced True RMS flexibility combined with extremeruggedness to withstand decades of daily abuse makes the $450 Fluke 179 the perfect investment. Alternative models like the Fieldpiece HS36 frankly lack the high-end capability necessary for balancing air handlers, testing motor windings, precision sensor measurement, and adjustment of variable frequency drives found across commercial sites. The same applies to sophisticated electronics technicians regularly debugging circuit boards or troubleshooting HVAC controller logic where rock-solid precision and advanced features prove essential. For these demand applications, the Fluke 179 stands alone as the de facto HVAC multimeter for anyone earning income dependent on accurate system
