Why Rheem? (Insider Comparison vs. Base 14 SEER2 Equipment from Other Brands)

We’ve been selling HVAC parts in Dallas-Fort Worth since 1998 — long enough to see which brands hold up and which don’t. This isn’t a marketing comparison; it’s what we see at the counter when those brands break and customers come in for replacement parts. We’re comparing apples to apples here: only the entry-level 14 SEER2 equipment of each brand, the same tier as our Rheem Select.

Two Tiers: Rheem Select (Affordable) vs. Rheem Classic (Premium)

Rheem Select 14 SEER2 condenser — the workhorse of the Select line, R-454B compliant, hailguard standard.

Most of our customers go with the Rheem Select line — it hits the DOE 2025 efficiency minimums, it’s the most affordable complete system you can buy that’s still Rheem-quality, and it pairs with the Rheem Classic furnace and coil for a balanced system that lasts. The pricing tables below are for Rheem Select condensers paired with Classic furnace/coil/air handler.

Heat Pump or Gas Furnace? Which Setup Is Right for Your Home

The single biggest decision when picking a complete system is whether the heating side runs on natural gas or on electric (heat pump). Here’s the honest take from selling these in DFW for 27 years:

Our take: if your house has a gas line, the gas furnace + condenser combo is the cheaper-to-operate choice every time. Heat pumps make sense when there’s no gas service, in newer all-electric subdivisions, or for solar-equipped homes that can offset the higher heating cost. Both setups are priced below in the Rheem Select line.

Pricing — Rheem Select 14 SEER2 Complete Systems

All prices below are walk-in, equipment-only, pre-tax. “Total Taxed” includes Texas sales tax. R-454B refrigerant compliant (the new DOE 2025 standard replacing R-410A). Pickup at our Dallas counter only — we don’t ship and don’t deliver. Hours: Mon–Fri 10 AM–7 PM, Sat 10 AM–3 PM.

Gas Systems — AC + 80% Gas Furnace + Evaporator Coil

The most common setup in DFW for homes with existing gas lines. Pairs a Rheem Select condenser with a Classic 80% AFUE upflow gas furnace and matching cased coil.

Electric Systems — AC + Air Handler + Heat Kit

For homes without natural gas (all-electric). Pairs the Rheem Select condenser with a Classic air handler and the appropriate heat kit (10kW or 15kW based on tonnage).

Heat Pump Systems — All-in-One Heating + Cooling

A heat pump replaces both your AC and your furnace — one outdoor unit handles cooling and heating. Most efficient in mild Texas winters. Pairs the Rheem Select heat pump condenser with a Classic air handler and electric backup heat kit for the few really cold days.

How to Pick the Right Tonnage

“Ton” in HVAC isn’t weight — it’s a measure of cooling capacity. 1 ton = 12,000 BTU/hour. For older, poorly-insulated DFW homes, the working assumption is 400 sq ft per ton. Better insulation pushes that number up — every improvement to the building envelope reduces the heat load and lets a smaller system keep up.

What raises your home’s R-value (and lowers the tonnage you need): insulated attic, properly ventilated attic, sealed/insulated walls, weatherstripped doors, dual-pane windows, and radiant barrier on the roof deck. A tight, well-insulated 2,000 sq ft home in Dallas can often run on 3 tons. The same 2,000 sq ft in a 1970s or 80s build with original single-pane windows and thin attic insulation legitimately needs 5 tons — the maximum size of a single residential system. Beyond that, you’re looking at zoning or a second system.

Here’s the Dallas-area sizing range — same square footage, very different answers depending on the building envelope:

Residential single-system equipment maxes out at 5 tons. Anything beyond that — or a poorly-insulated home over ~2,500 sq ft — needs zoning or two separate systems. A 2,000 sq ft 1970s/80s home in Dallas with original windows and minimal attic insulation legitimately needs 5 tons; the same square footage in a 2010+ build with R-38 attic insulation and dual-pane windows runs fine on 3 tons.

Insulation matters more than square footage. Two homes the same size in DFW can need very different tonnage depending on insulation, ceiling height, sun exposure, and window count. If your existing system has been keeping up fine, match its tonnage. If it has always struggled in July/August, go up half a ton or look at insulation upgrades first.

The fastest way to know for sure: bring us a photo of your existing condenser’s data plate (the metal sticker on the side of your outdoor unit). The first two digits of the model number after a letter — like “036” or “048” — tell us your current tonnage in thousands of BTU. A 36 = 3 ton, 48 = 4 ton, 60 = 5 ton. We’ll match it or recommend an upgrade if your current system was undersized.

A complete Rheem system: outdoor condenser, indoor furnace or air handler, and matched evaporator coil — everything you need from us in one purchase.

The Buying Process — What to Expect

1. Confirm the size you need by phone or in person. Bring photos of your current outdoor unit data plate and your indoor air handler/furnace. Call (214) 340-9421.
2. We’ll quote the exact components for your situation — Select condenser + matching Classic furnace/AH/coil — and confirm in-stock availability.
3. You pay and pick up at the Dallas counter (10226 Plano Rd, Suite 104). Most systems fit in a pickup truck or small trailer. Larger sizes may need a flatbed or two trips.
4. You install yourself or have your installer install. We don’t do installation — we sell the equipment. If you’re not doing it yourself, your handyman or HVAC tech can install a complete system in 4–8 hours.
5. Bring back the old equipment if you want — we don’t take trade-ins, but we can recommend disposal options.
6. Register the warranty within 60 days at Rheem.com/warranty for full 10-year parts coverage.

Installation Site Prep — What You’ll Also Need

The complete system gives you the AC, furnace, coil, and any required heat kit — but a real installation needs more than just the major components. Most installers (or DIYers) also need these supplies, which we keep in stock:

Picking Up Your System — What to Bring, What to Expect

We’ve got an untraditional warehouse and a tight crew, so here’s how pickup actually works at our Dallas counter:

• Bring a pickup truck or trailer. A full residential system (condenser + furnace + coil + heat kit if applicable) won’t fit in a sedan or small SUV. The condenser alone runs from ~150 lbs (1.5 ton) to ~250 lbs (5 ton). The indoor unit is similar in weight.
• We load you up. We use a scissor-lift table at the counter — same idea as a forklift, but tighter for our space. You don’t need to bring help; we handle the heavy lifting onto your vehicle.
• Bring tie-down straps. Once we load it, you’re on your own for securing the load. We don’t supply straps. Pick a couple up at any auto parts store if you don’t have them.
• Have your model numbers ready. If you’re matching to an existing system or replacing a specific size, bring photos of the data plates from your old condenser and furnace/air handler. Saves time at the counter.
• Plan for the same-day install (or storage). If you’re not installing immediately, the indoor unit needs to stay dry and indoors. The condenser is fine outside but should be covered.
• Cash, debit, credit all accepted. Net-30 available for established commercial accounts.

Hours: Mon–Fri 10 AM–7 PM, Sat 10 AM–3 PM. Closed Sunday. Showing up 30 minutes before close is fine — we won’t rush you.

Frequently Asked Questions

Why Buy Direct From Us Instead of Calling an HVAC Company?

A typical full-service HVAC company charges $7,000–$12,000 for a complete 3-ton system replacement in Dallas. Their cost on the equipment is usually around $3,500–$4,500 (close to our retail). The other $3,500–$8,000 is installation labor, overhead, financing markup, and profit margin.

If you’re handy or know an installer, buying the equipment from us and paying a separate installer for labor cuts the total cost roughly in half:

• Equipment from us (3-ton gas): $3,448
• Install supplies (pad, whip, disconnect, line set, brazing, PVC): $200–$400
• Independent installer labor (1 day): $400–$1,200
• Total DIY-with-installer cost: ~$4,500
• Same job through a full-service HVAC company: $9,000–$11,000

The $5,000+ difference is real — and it’s the same equipment with the same warranty either way.
