What Makes the RunTru A951X Furnace Different
An 80% furnace sends a good share of its heat up the flue as hot exhaust. The A951X adds a secondary heat exchanger that pulls so much heat from the combustion gases that water vapor condenses out. That is how it reaches 95% AFUE: roughly 95 cents of each fuel dollar warms your rooms.
The trade-off is plumbing. Cool exhaust leaves through PVC vent pipe instead of a metal flue, and the furnace produces acidic condensate that needs a drain, just like the AC coil sitting on top of it. Floridians already understand condensate lines, but a furnace adds one more to keep clear.
When a 95% Furnace Earns Its Keep in Florida
Because heating hours are limited here, the case for condensing heat is situational. It tends to make sense when:
- The old metal flue is deteriorated or does not meet current code
- You are moving the furnace and a new chimney route would be awkward
- The home runs on propane, where every fuel dollar counts
- Someone in the household keeps the house warm all winter
- You plan to stay long enough to recover the higher upfront cost
- A qualifying rebate narrows the price gap (see current offers)
Converting From an 80% Furnace to the A951X
Route new venting
We plan intake and exhaust PVC runs through a wall or roof with proper slope back to the furnace.
Retire the old flue
If a water heater shares the old vent, we confirm it still drafts correctly on its own.
Add drainage
The condensate trap and drain are tied in, often alongside the AC coil's existing line.
Commission and test
Gas pressure, temperature rise and drain flow are verified before we leave.

Common Questions
RunTru A951X Furnace Installation & Service — FAQs
What affects RunTru A951X price?
The biggest variables are furnace size, how far the new PVC venting must run, condensate drain routing, and whether the AC coil is replaced at the same time. Converting from an 80% unit costs more than a like-for-like swap. We quote a firm flat rate after visiting, and financing is available on approved credit.
Is the RunTru A951X worth it in Florida?
Sometimes. If your existing flue is in good shape and you rarely run heat, an 80% model like the A801X is often the smarter buy. The A951X makes more sense with a failing flue, propane fuel, a relocated furnace, or a household that keeps the heat on through every cold spell.
What maintenance does a condensing furnace need?
Everything an 80% furnace needs, plus attention to the condensate trap, drain line and PVC vent terminations. Algae and debris that clog AC drains can affect furnace drains too. A yearly inspection through our maintenance program covers both.
How long does an A951X installation take?
A direct replacement of an existing condensing furnace often takes a day. Converting from an 80% furnace can take longer because of new vent routing and drain work. We schedule the job with the timeline spelled out in your quote.
Why is my A951X blowing cold air?
Common causes include a clogged condensate trap tripping a pressure switch, a dirty flame sensor, or a failed igniter. Check the filter and thermostat first, then call our repair team at (941) 417-4848.
