Home Checkup
No obligation. Same lead path as our contact form — owner-run follow-up, not a PE call center.
By type of home
Choose your home type — I’ll show you which system works best
A 1920s Carnegie brick house with a boiler and a 1990s Mt. Lebanon two-story need different answers. Pick the home that sounds like yours and we’ll show what genuinely fits a Pittsburgh winter — then confirm it with a Manual J load calculation on site.
Pick the home that sounds like yours
Showing guidance for Brick Victorian / Craftsman.
Brick Victorian / Craftsman: what actually fits
- Usable ductwork is rare — forcing oversized central equipment through plaster is invasive and expensive.
- Many still run hydronic heat (boilers/radiators) that neighbors love when it’s maintained.
- Cold Allegheny winters punish undersized electric-only gear that was designed for mild climates.
Best fit for most
Ductless multi-zone heat pump (cold-climate)
The standard retrofit when ducts don’t exist: indoor heads need only a small wall penetration, each zone gets its own control, and cold-climate models are sized for real Pittsburgh design temperatures — not Sun Belt averages.
Ductless & heat pump optionsWorth comparing
Keep / modernize the boiler + add cooling zones
If the hydronic system is healthy, preserving it and adding ductless cooling (or a high-efficiency boiler swap) is often smarter than ripping out radiators homeowners still prefer.
Boiler & heating servicesPittsburgh reality: we design for your house, not a spreadsheet tonnage label. Expect a signed 26-point install standard on replacements and flat-rate diagnostics before anyone sells you a truckload of equipment.
Ranch / Cape / Split-Level: what actually fits
- Where ducts exist they’re often 50+ years old — leaky, undersized runs waste the air you paid to condition.
- Upstairs/downstairs splits and finished basements create uneven comfort the original furnace never solved.
- Single-story and split layouts make both ducted upgrades and multi-zone ductless practical.
Best fit for most
High-efficiency furnace + AC (or dual-fuel)
If ducts test out, a properly sized furnace/AC or dual-fuel heat pump reuses them for whole-home comfort. We measure before we swap — 1960s ductwork feeding new equipment is where bad installs go wrong.
Heating & cooling servicesWorth comparing
Ductless multi-zone heat pump
When ducts are a lost cause — or you want room-by-room control without a full duct rehab — cold-climate ductless is the clean retrofit path for ranches and splits.
Ductless optionsPittsburgh reality: Peoples Gas and Duquesne Light incentives can change the net math. We verify what’s current for your address at quote time — see our rebate finder — instead of quoting expired federal credits.
Suburban Two-Story: what actually fits
- You already own the expensive part: a complete duct system.
- Upstairs-hot / downstairs-cold is usually airflow and stratification — not “buy a bigger furnace.”
- Many were built with weak cooling for today’s humid Pittsburgh summers.
Best fit for most
Dual-fuel heat pump (or high-efficiency furnace + AC)
Dual-fuel keeps gas as cold-snap backup while a heat pump carries milder days — a strong fit for Allegheny winters and rising summer humidity. Manual J sizing stops the short-cycling that oversized swaps create.
Heat pump & dual-fuel optionsWorth comparing
Right-sized furnace + AC with duct balancing
If you’re staying on gas, a modern furnace plus properly sized AC fixes comfort now — duct sealing and balancing are what actually tame the upstairs/downstairs split.
Furnace & AC servicesPittsburgh reality: Synchrony financing (including 0% up to 60 months on qualifying equipment) can pair with utility rebates. We publish Pittsburgh price bands so you can budget before the visit.
Boiler / Radiator Home: what actually fits
- Boiler work is a specialty — many PE call-center brands quietly avoid it or push a forced-air rip-out.
- Near-boiler piping, venting, and circulators matter as much as the boiler badge.
- Cooling still needs a plan: ductless zones or a separate AC path without destroying the radiators you like.
Best fit for most
High-efficiency boiler replacement (when justified)
When the boiler is at end of life, a properly piped high-efficiency replacement preserves the comfort character of the home. We diagnose first — sometimes a circulator, zone valve, or safety fix beats a full swap.
Boiler servicesWorth comparing
Keep the boiler + add ductless cooling
Hydronic heat + ductless cooling is a classic Pittsburgh combo: radiators for winter, heads for sticky summers, no forced-air conversion required.
Ductless cooling optionsOwner-run reality: Six Star still does boilers. If another quote only offers “rip it out for a furnace,” bring it for a free second opinion — we’ll say so if the other bid is fair.
Townhome / Condo: what actually fits
- Mechanical space is tight — full-size equipment often doesn’t fit.
- Outdoor-unit placement may need HOA or association sign-off.
- Quiet operation and compact footprints matter more than brochure tonnage.
Best fit for most
Compact ducted or slim ductless heat pump
Slim-duct and wall-mounted systems are built for tight closets, small side yards, and shared-wall noise limits — heating and cooling from one cold-climate package.
Compact system optionsWorth comparing
Single- or dual-zone ductless
For wall-heater or under-served units, one or two heads deliver comfort without chasing ducts through party walls — usually the least invasive HOA path.
Ductless optionsPittsburgh reality: we document equipment placement and sound levels so association boards get paperwork they can actually review — not a sales flyer.
One Problem Room: what actually fits
- Rooms outside the original design — over garages, attics, additions — rarely get fixed by “a bigger furnace.”
- Oversizing the whole house to chase one room makes comfort worse.
- Sometimes the honest answer is airflow (returns, sealing, one new run) — not new equipment.
Best fit for most
Single-zone ductless for that room
Purpose-built for the one-room problem: its own thermostat, its own capacity, quiet — and it stops the rest of the system from overworking.
Ductless for problem roomsWorth comparing
Airflow fix on your existing system
Duct sealing, balancing, or a properly sized new run can rescue a starved room without a full replacement. We measure first — if the fix is equipment-free, we’ll say so.
Diagnostics & repair pathPittsburgh reality: South Hills two-stories and brick colonials throw this problem constantly. Tag it on our interactive home checkup, then we’ll confirm on site.
Every Pittsburgh home is different — this is honest general guidance, not a system specification. The right answer comes from an on-site evaluation and a Manual J load calculation when sizing matters. Six Star quotes flat-rate after diagnosis — no PE call-center script.

Our standards
How we got our stars
Six principles that shape every service call, maintenance plan, and commercial partnership—from reliability on the schedule to the culture behind the crew at your door.
RELIABILITY
“If we say it's handled, it's handled.”
We show up when we say we will.
Commercial clients depend on predictable response times. Homeowners depend on follow-through. Reliability is non-negotiable and it is the foundation of our service agreements and block hour programs.
CONSISTENCY
“Consistency beats intensity.”
We focus on planned service, maintenance, and long-term system care instead of emergency-driven chaos.
Consistent systems create consistent results. That's why we lead with block hours and service agreements.
ACCOUNTABILITY
“We own the outcome.”
Before, during, and after the job, we take responsibility.
No finger-pointing. No disappearing after the invoice is paid.
We don't just install systems — we support them.
PROFESSIONALISM
“Prepared. Respectful. Organized.”
Our crews operate with training, structure, documentation, and clear communication.
Professional service isn't optional — it's expected.
LONG-TERM PARTNERSHIP
“We think in years, not invoices.”
We're not chasing transactions.
We help clients plan ahead, control costs, and avoid surprises.
That's why commercial service agreements and block hours are central to how we operate.
PEOPLE FIRST
“Take care of the team. The team takes care of the customer.”
Great service starts internally.
By prioritizing training, culture, and work-life balance, our team shows up focused and engaged.
We don't run a burnout model — and our clients benefit from that stability.
