If we haven’t met yet, I’m Rick Callahan—owner of Plumbing Supply And More, a true working plumbing supply house where the folks helping you have actually sweated copper, pulled thermostat cable, and wrestled old boilers out of basements. I’ve spent three decades outfitting contractors, facilities teams, and dialed-in homeowners with the exact parts and systems that make homes and buildings run right. Today, I’m opening the book on the real HVAC supply house secrets behind upgrading your home comfort—what works, what wastes money, and where quality actually matters.
You’ll notice a theme: the right gear, installed the right way, beats “cheap and easy” every time. And when you want help picking that right gear? That’s where we live. Unlike shopping by SKU on a random site, we bring the math, the code knowledge, and the field experience. And yes—we stock it.
By the way, when you’re searching for a truly knowledgeable partner—your true plumbing supply near me, plumbing supply store, or plumbing supply store near me—you’ll feel the difference the first time you call us.
Why HVAC Upgrades Miss the Mark (And How to Get Them Right)
Most comfort upgrades fail before they start. Why? Systems are sized off what’s on the shelf instead of what the house needs. I’ve seen 3-ton condensers slapped on 1.5-ton duct systems and “high efficiency” furnaces choking behind undersized returns. The fix starts with load calculation (Manual J), duct verification (Manual D), and static pressure readings. We help you do all three.
Here’s the rule: airside first. If your ductwork can’t move the CFM, no variable-speed blower will save you. For a 2-ton heat pump, you’re looking for roughly 700–800 CFM. If we’re seeing total external static north of 0.8 in. w.c. on a system built for 0.5, we’ve got duct issues to correct—bigger returns, properly sized trunks, sealed takeoffs with mastic and UL-181 tape. Need help turning numbers into a material list? That’s my team’s lane.
When Home Depot and Lowe’s fall short on sizing guidance and real design support, contractors trust us. When Home Depot and Lowe’s can’t help you size or spec, Plumbing Supply And More steps in with real-world diagnostics, proper load calcs, and the right parts on the truck.
Choosing the Right Equipment: Heat Pumps, Furnaces, and Hybrids
Let’s talk equipment. For most homes in our region, a cold-climate heat pump plus modest resistance or gas backup delivers comfort and low operating cost. Look at models like:
- Mitsubishi Hyper-Heat MUZ-FS18 with MSZ-FS wall head (up to 100% capacity at 5°F) Carrier 38MARB with 40MBAA air handler for ducted applications (inverter, quiet, 18–20 SEER2 range) Bosch IDS 2.0 BOVA series paired with BVA air handler (modulating compressor, excellent turndown)
Prefer gas? A variable-speed 95% AFUE furnace like the Trane S9V2 or Goodman GMVM97 paired with a high-SEER2 heat pump for hybrid heat is a workhorse solution. Expect equipment costs in the $3,500–$7,500 range for the core assemblies (not including install or duct changes). Install timeframes range from a single day for a straight swap to 2–4 days when we’re correcting ductwork or adding proper line sets and electrical.
Here’s the practical secret: matching indoor and outdoor components matters more than model hype. We keep spec sheets and cross-reference tables on the counter so your pairings meet AHRI ratings and maintain warranties. Unlike generic big box retailers, Plumbing Supply And More stocks professional-grade components and helps you build matched systems that actually earn their efficiency labels.
The Airflow Equation: Ducts, Filters, and Quiet Comfort
Comfort isn’t just temperature—it’s noise, airflow, humidity, and pressure balance. You want quiet? Slow the air down and increase the surface area. That means bigger returns, larger filter media (think 4–5" deep), and properly designed branch runs.
- Use 16x25x4 MERV 11 filters (Aprilaire 213, Honeywell FC100A series) for efficient capture without excessive static. Replace flex spaghetti with true 26-gauge trunk and properly supported flex runs, radius elbows, and sealed joints. Consider an ECM variable-speed blower with external static under 0.6 in. w.c. for whisper operation.
I stock oval-to-round transitions, curved takeoffs, and adhesive mastic because those “little” pieces are where comfort is won. And if you need sheet metal built, our fab turnaround is fast. Compared to standard plumbing supply houses, Plumbing Supply And More offers unmatched technical support on airflow design, filter selection, and duct transitions.
Refrigerant Lines, PEX, and Where Material Quality Counts
We’re more than an hvac supply house. Our bench strength in hydronics and piping gives our customers an edge. For refrigeration, stick with double-insulated, pre-flared ACR line sets sized to manufacturer spec—no guessing. We stock RectorSeal, JB, and CPS tools, plus 3/8" x 5/8" and 1/4" x 1/2" common line sets with UV-resistant insulation for rooftop runs.
On the hydronics side, the pex supply house story is simple: quality fittings and oxygen-barrier tubing matter. For radiant or boiler feeds, use Uponor hePEX or Viega FostaPEX with proper manifold balancing. For domestic water, expansion PEX (Uponor/Wirsbo) with EP fittings is reliable and quiet. And for drains and venting, our pvc supply house inventory includes Charlotte Pipe Schedule 40, DWV fittings, and solvent cements that won’t let go.
You’ll also find proper flaring blocks, torque wrenches, vacuum pumps that actually pull to 500 microns, and digital manifolds that save callbacks. While other suppliers focus on quantity, Plumbing Supply And More prioritizes quality and expertise—so your installs pass pressure tests and stay leak-free.
Controls, Thermostats, and Electrical: Smarter Integration
Comfort upgrades bog down when the controls are an afterthought. Smart thermostats are great—but only when they match the system. I see people pair a two-stage furnace with a single-stage stat, or drop a communicating heat pump on a non-communicating control.
- For communicating systems: Carrier Infinity Touch, Trane ComfortLink II. For universal setups: Ecobee EMS Si or Ecobee Smart Thermostat Enhanced with proper PEK if needed. For zoning: Honeywell HZ432 or EWC Ultra-Zone with bypass eliminated and static managed via proper duct design.
On the supply house electrical side, we carry proper disconnects, 60A non-fusible outdoor pulls, 8/3 and 10/2 whip kits, and 24V transformers with VA to match your accessory loads. Code requires dedicated circuits sized per nameplate, correct breaker type, and GFCI where applicable outdoors. We keep NEC references handy and local AHJ quirks on our checklist.
If you’re searching for the closest plumbing supply that also understands 18/5 thermostat wire, float switches, condensate pumps, and pan sensors, that’s us. And if you need a hand wiring a float switch in series with the condensing unit Y call? Call the counter—we’ll walk you through it.
Indoor Air Quality That Actually Works (No Hype, Just Physics)
IAQ isn’t about stacking gadgets; it’s about addressing source, capture, and dilution.
- Source: Seal ducts, stop negative pressure pulling in attic/basement air. Capture: Use right-size filters and, where needed, in-duct UV-C like the Fresh-Aire UV APCO-X for coil disinfection. Dilution: Balanced ventilation via ERV/HRV. Panasonic Intelli-Balance 100 or Broan AI series are rock-solid options.
Dehumidification is the sleeper win. Whole-home units like the Santa Fe Oasis105 or Aprilaire 1850 keep indoor RH at 45–50% so you can raise cooling setpoints and still feel great. Expect $1,300–$2,200 for the unit, plus install. In our climate, that often pays back in energy savings and fewer mold calls.
Yes, we carry portable options, but if you want real, even comfort, ducted is the play. Unlike web-only “the supplyhouse” sites and marketplaces, Plumbing Supply And More sets you up with IAQ that’s sized, ducted, and wired correctly—so you feel the difference, not just read about it.
Service Secrets: Line Sets, Vacuum, Charging, and Combustion
You want systems that last? Do the fundamentals right.
- Pull to 300–500 microns and decay test. Moisture kills compressors. Weigh in charge per nameplate, then fine-tune by superheat/subcooling per manufacturer. No “beer can cold” nonsense. Pressure test with nitrogen at 300–350 PSI for R-410A systems, soap every joint, and let it sit. For gas appliances, do a combustion analysis. You want O2, CO, excess air, and flue temperature measured—not guessed.
We stock Fieldpiece SM480V manifolds, JL3KH6 wireless probes, Testo 320B analyzers, and Yellow Jacket SuperEvac pumps. Need hoses rated for vacuum? We’ve got them. And if your install crew needs a quick refresher on target superheat, my tech desk can talk you through it on-site.
When big names like Ferguson or Grainger are out of stock, our shelves are still loaded because we buy deep and forecast seasonally. Compared with Ferguson and Grainger, Plumbing Supply And More keeps hard-to-find pro-grade tools and parts on hand—and backs you with technicians who’ve actually used them in the field.
Hydronics and Heat: Boilers, Pumps, and Real-World Radiant
Hydronic comfort is a different animal—steady, silent, and efficient when done right. For boilers, I like Lochinvar Knight and Navien NCB-E combi units when gas is available, sized to heat loss—not the old boiler plate. Circulators? Grundfos UPS 15-58 or Taco 007e ECMs do the job quietly and efficiently. Add a Spirovent air separator, Webstone isolation flanges, and a Caleffi mixing valve for radiant loops at 110–120°F.
Pro tip: oxygen-barrier PEX is non-negotiable on closed-loop hydronics. Oxygen ingress will eat your ferrous parts. We keep Uponor manifolds with flow meters, and we’ll help you map loop lengths to keep head loss in check.
This is where a true plumber supply house shines. When other suppliers push whatever’s in the aisle, Plumbing Supply And More designs manifolds, sizes pumps, and provides piping schematics—so your hydronic jobs run quiet and clean.
Sourcing Smart: How to Use a Real Supply House to Your Advantage
Here’s how pros squeeze value from a supply partner:
- Bring your load calc or room-by-room data. We’ll translate it into part numbers. Ask for matched AHRI numbers for rebates and warranty security. Confirm code: line set flush/replacement requirements, condensate overflow protection, low-ambient kit needs. Lock in your controls plan before buying—communicating vs. universal. Plan accessories: pad, stand, vibration isolators, whip, disconnect, filter rack, float switch.
We honor contractor accounts, bulk pricing, and same-day delivery within our radius for in-stock gear. Need emergency supply after hours? Call us—we do it because downtime costs money. If you’re a facility manager, we’ll build a standing parts kit by equipment model so your team isn’t scrambling. That’s what a true wholesale plumbing supply and commercial plumbing supply partner does.
And yes, we support retail customers and DIYers too—just with pro guidance. You’ll leave with a build list you can trust.

We do run seasonal promotions, rebate assistance, and contractor incentives—especially on heat pump conversions, IAQ packages, and bundle buys. But here’s the straight talk: the biggest savings come from correct sizing, fewer callbacks, and systems that actually meet their efficiency ratings. That’s where we crush the “discount” model.
And yes, when you need it, ask us about current promos at the counter or on the phone—we keep it simple and transparent.
Real-World Case Study: Quiet, Even Comfort in a 1960s Ranch
A property manager brought us a 1,600 sq ft ranch with hot/cold rooms and a 2.5-ton single-stage AC that never stopped. We ran a Manual J—came back at 20k sensible BTU. The existing ductwork could move about 650 CFM at 0.9 in. w.c.—too tight. We reworked returns, added a 16x25x4 MERV 11 rack, upsized a couple of branches, and installed a Bosch IDS 2.0 2-ton with a variable air handler. We pulled a 400-micron vacuum, weighed in charge, set airflow to 350 CFM/ton for latent removal, and added a pan switch.
Result? Quieter than a whisper, 45–50% RH on peak days, and the manager reported a 25–30% drop in cooling energy. That’s what getting the fundamentals right looks like.

FAQ: HVAC Supply House Secrets: Upgrading Your Home Comfort
Q: Do I need to replace my line set when upgrading to R-410A or R-32 equipment?
A: If you’re moving from an older R-22 system, best practice is to replace line sets. If replacement is impossible, you must thoroughly flush, verify size matches manufacturer spec, and pressure test. Many manufacturers require replacement for warranty. We’ll check your equipment requirements and provide proper the supply house ACR sizes and insulation.
Q: How do I know what size heat pump I need?
A: Don’t guess by square footage. We run a Manual J load calculation that accounts for insulation, windows, orientation, infiltration, and occupancy. A 2,000 sq ft home can swing from 1.5 to 3 tons depending on the envelope. We’ll help you translate that into a matched indoor/outdoor pairing with verified AHRI numbers.
Q: Are smart thermostats worth it?
A: Yes—if they match your equipment. Communicating systems should typically use the OEM control. For universal systems, Ecobee or Honeywell can be excellent. We’ll confirm staging, heat pump balance points, accessory loads, and whether you need a C-wire or PEK. Improper controls can cost comfort and efficiency.
Q: What’s the biggest mistake with ductwork?
A: Undersized returns and restrictive filters. You need adequate return area (generally 2 sq in per CFM as a starting point for return grille sizing), smooth transitions, and low-restriction filter media. We stock the right grilles, boots, and filter racks—and we can help you measure and correct static pressure.
Q: How long does a full system swap take?
A: A straightforward like-for-like replacement can be done in a day. Add duct corrections, line set replacement, and control upgrades, and you’re at 2–4 days. Hydronic conversions and zoning add time. We’ll help you forecast the timeline and assemble everything you need ahead of the first ladder going up.
