What's included
What our boiler installation service includes
Every boiler installation waco TX job we quote includes the work below. If something on your property needs extra attention, we tell you before we start, not after the invoice arrives.
Heat-loss sizing calculation
We measure every room, check insulation and window count, and calculate the actual BTU load. This is the step that separates a boiler that runs efficiently for 20 years from one that short-cycles and fails early.
Permit and inspection
We pull the mechanical permit with the city and meet the inspector on site. You get a documented, code-correct installation that will not become a problem when you sell the house or refinance.
Removal and disposal
We drain, disconnect, and haul away the old boiler and any failed near-boiler components. The area is left clean enough to store boxes, and we recycle the metal rather than leaving it on your curb.
Piping, venting, and controls
New supply and return piping where needed, code-correct venting, a new expansion tank, and a tested relief valve. We set the aquastat and wire the zone controls so the system runs the way it was designed.
Commissioning and walkthrough
We pressure-test, purge air, verify gas pressure at the manifold, and run a combustion analysis. Then we walk you through the settings, leave the manuals, and register the manufacturer warranty for you.
Service overview
What boiler installation waco TX really involves
Boiler installation waco TX is the process of removing or bypassing an old heat source, sizing a new boiler to the building's actual load, and tying it into the existing piping, controls, and venting so it runs safely and efficiently. It is not a swap-in-a-box job. We calculate heat loss, check gas supply and flue routing, verify clearances, and confirm the unit meets current mechanical code before a single fitting is soldered. On a typical Waco home that means a half-day to two days on site, depending on whether we are replacing like-for-like or reworking the near-boiler piping.
Local experience matters here. Waco's mix of older pier-and-beam homes, post-war ranches, and newer builds means we run into everything: undersized gas lines, corroded black-iron headers, and venting that was fine in 1985 but fails a modern inspection. If you are searching boiler installation near me waco because the current unit is limping through another winter, we can usually tell you on the first visit whether a repair buys you time or whether a new boiler installation waco TX is the smarter spend. We also handle commercial boiler installation waco for small shops, churches, and rental properties around the county.
How we workWe verify the cause, compare realistic options, and confirm the repair before we leave.
The service timeline
How our boiler installation process works
The process flexes to the condition, but these checkpoints keep decisions clear.
On-site assessment
We measure the building, count radiators or baseboard zones, check the gas meter and supply line size, and inspect the existing flue and venting. On most homes this takes 45 to 60 minutes. You get a written quote the same day with the boiler model, efficiency rating, and what is included.
Sizing and equipment selection
We run a room-by-room heat-loss calculation, then match the boiler to the load. For most Waco homes that lands between 80,000 and 140,000 BTU. We stock and install Carrier, Trane, Lennox, Rheem, and Goodman equipment, so you are not locked into one brand or one price point.
Removal and prep
We isolate the gas and water, drain the old boiler, and haul it out. Then we inspect the near-boiler piping, the expansion tank, and the circulators. Anything corroded or undersized gets flagged before we set the new unit, so you are not paying twice for the same repair a year from now.
Install and commissioning
We set the boiler, pipe it in, wire the controls, and connect the venting to code. Then we fill, purge, and pressure-test the system, set gas pressure at the manifold, and dial in the aquastat. A standard residential swap is a one-day job. More complex retrofits run two days.
Walkthrough and handoff
Before we leave, we walk you through the thermostat or aquastat settings, show you how to check the relief valve, and leave the manuals and warranty paperwork. We register the manufacturer warranty for you and schedule your first annual tune-up. If anything is not right in the first 30 days, we come back at no charge.
Tools & methods
Tools and methods behind our boiler work
Purpose-built equipment, used by trained technicians, so the job is done accurately the first time.
Combustion analyzer
Measures oxygen, carbon monoxide, and stack temperature so we can dial in the air-fuel mixture. It is how we verify a boiler is running at its rated efficiency, not just running.
Manifold gauges
Used to verify gas pressure at the manifold and check system pressures on hot-water loops. Incorrect gas pressure is one of the most common causes of poor combustion and short boiler life.
Vacuum pump
Pulls a deep vacuum on the system when we are working on related refrigerant equipment or heat pump components. It is the same discipline we apply to boiler purging and pressure testing.
Refrigerant recovery machine
Required for any job that touches refrigerant, including heat pump and AC work we often pair with boiler replacements. It keeps us EPA-compliant and keeps your system charge correct.
HVAC diagnostic tools
Multimeters, clamp meters, and thermometers that let us test controls, circulators, and zone valves in one visit instead of guessing and ordering parts.
Duct cleaning equipment
When we find duct leaks or dirty ductwork during a boiler job, we can clean and seal it the same visit. That protects the efficiency of the whole system, not just the boiler.
Use cases
When Waco property owners call us for boilers
These examples show how the service framework adapts rather than forcing every call through one repair.
Bellmead duplex, steam to hot-water conversion
A 1960s steam boiler with failed low-water cutoff and banging pipes. One tenant had been without reliable heat for two weeks, and the owner was facing a repair quote close to half the replacement cost. → We converted the duplex to a hot-water system with a new 120,000 BTU boiler and new baseboard in both units. Installation took two days, the permit passed inspection the next business day, and both tenants had heat that week.
Lacy-Lakeview church, emergency commercial replacement
A commercial boiler failed three days before a holiday service. The sanctuary was 58 degrees, and the existing unit was 24 years old with a cracked section. → We sourced a commercial boiler, installed it over two days, and had the sanctuary back to 70 degrees before the service. We also found and sealed a duct leak in the fellowship hall during the same visit.
Problems we solve
Boiler problems we solve for Waco homeowners
Most boiler calls fall into a handful of categories. Here is what we see most often in Waco and how we handle it, whether you need a repair or a full boiler replacement waco Texas job.
Boiler runs but the house stays cold
We check circulators, zone valves, and air in the lines before we blame the boiler. Often a $300 to $600 repair restores full heat. If the heat exchanger is cracked or the unit is undersized, we quote a replacement with the numbers to back it up.
Relief valve dripping or boiler losing pressure
We test the relief valve, check the expansion tank charge, and inspect the fill valve and backflow preventer. Most of these are same-day repairs, and we replace the tank with a properly sized unit rather than just topping off the pressure.
Old boiler is 20-plus years old and noisy
We do a combustion analysis and inspect the heat exchanger. If repair is throwing money at a dying unit, we quote a high efficiency boiler installation waco TX 76701 replacement with a 90% to 96% AFUE unit and a written price before we start.
Gas smell or combustion concern
We treat gas and combustion calls as emergencies. We shut the unit down if needed, test with a combustion analyzer, inspect the flue, and repair or replace the failed component before we restore operation.
Pricing process
What boiler installation costs in Waco
$4,200 - $8,500 installed for most residential replacements; commercial quotes after site visit
Boiler size and efficiency
A standard 80% AFUE boiler costs less than a 95% condensing unit, but the condensing unit usually pays back the difference in four to six winters. We quote both so you can see the math.
System type
Hot-water systems are simpler to replace. Steam systems and conversions from steam to hot water involve more piping, traps, and controls, which adds labor and materials.
Venting and gas supply
If the existing flue or gas line is undersized for the new boiler, we have to upgrade it. That is a real cost, and we flag it during the assessment rather than surprising you on install day.
Customer reviews
What Waco customers say about our boiler work
★★★★★
“Our 22-year-old boiler finally gave out in January. Waco Air Conditioning & Heating had a tech out the same afternoon, quoted a replacement in writing, and installed it two days later. They pulled the permit, met the inspector, and walked me through the aquastat settings. Gas bill dropped about $45 the first month.”
★★★★★
“I manage four rental houses in Bellmead and had two boilers on their last legs. They replaced both, handled the permits, and registered the warranties for me. What sold me was the follow-up call a month later to check the systems. That is not something I get from most contractors.”
★★★★★
“Our church boiler failed before the Christmas service. They treated it as an emergency, sourced a commercial unit, and had heat back in the sanctuary in three days. They also found a duct leak in the fellowship hall while they were there and fixed it the same visit.”
How much does boiler installation cost in waco TX?
Most residential boiler replacements in Waco run $4,200 to $8,500 installed, including permit, removal, and commissioning. High-efficiency condensing units and complex retrofits push toward the top of that range, while a straightforward like-for-like swap on a standard 100,000 BTU unit often lands near the bottom. Commercial boiler installation waco pricing depends on load and venting, so we quote those after a site visit.
How long does boiler installation take in waco?
A standard residential swap is a one-day job, typically 6 to 9 hours on site. If we are reworking near-boiler piping, adding zones, or converting from steam to hot water, plan on two days. We schedule the gas inspection for the next business day and do not leave you without heat overnight unless the old unit was already dead.
What size boiler do I need for my waco Texas home?
Most Waco homes land between 80,000 and 140,000 BTU, but the right number comes from a room-by-room heat-loss calculation, not square footage alone. Insulation, window count, ceiling height, and how much of the house you actually heat all move the number. An oversized boiler short-cycles and wears out early, so we size it properly before we quote.
Who installs boilers in waco TX?
Licensed mechanical contractors with boiler experience, current permits, and the tools to commission the system correctly. We hold EPA Certification and NATE Certification, work under a State HVAC License, and carry combustion analyzers and manifold gauges on every truck. Ask any installer for their license and permit plan before you sign, because that is the difference between a warranty and a headache.
