Boiler Repair and Installation in Tempe, Arizona – Hydronic Heating Expertise You Can Trust
We are Tempe Heating and Air Pros, and we are the trusted local boiler repair and installation experts in Tempe. Boilers are not the most common heating system in Tempe homes, but the properties that have them need a service team that actually understands hydronic heating — not one that treats a boiler like an unusual furnace with different plumbing. We work on boiler systems with real technical depth, from diagnosing circulator pump failures in older Tempe properties to installing complete hydronic heating systems in custom homes and specialty applications throughout the area.
Boilers appear in Tempe properties across several contexts: older commercial-to-residential conversions near downtown Tempe, custom homes where radiant floor heating was specified for comfort and efficiency, specialty historic properties with original radiator systems, and some condominium buildings with central hydronic heating distribution. Each of these installations is different, and the approach to servicing them should reflect that. We evaluate every boiler system as its own configuration, understand how the complete hydronic loop is designed to work, and diagnose problems from that whole-system perspective.
If you have a boiler in your Tempe property that needs repair, maintenance, or replacement, you are dealing with a system that deserves specific expertise. That is what we provide.
Our Boiler Repair and Installation in Tempe Arizona
Boiler Repair
When a boiler in a Tempe property stops heating correctly, the diagnostic process is different from what a forced-air furnace repair involves. A boiler operates as part of a complete hydronic system — the boiler itself, the circulator pump or pumps, the zone valves, the expansion tank, the pressure relief valve, and the distribution network of pipes, radiators, or radiant loops. A problem anywhere in that system can manifest as a lack of heat, and identifying the actual source requires evaluating all of it, not just the boiler cabinet.
Common Problems We Fix
- No heat from radiators or radiant floor zones despite the boiler appearing to fire normally
- Pressure relief valve leaking, dripping, or discharging water onto the floor near the boiler
- Circulator pump running but producing little or no water flow through the hydronic system
- Air trapped in the hydronic lines causing banging, gurgling, or uneven heat distribution between zones
- Expansion tank failure causing system pressure to spike or drop outside the normal operating range
- Zone valve that will not open or close correctly, leaving one area of the home without heat
- Pilot or electronic ignition failure on a gas-fired boiler preventing the burner from lighting
- Leaks at pipe fittings, boiler connections, or through the heat exchanger itself
- Low water cutoff malfunction preventing the boiler from firing as a safety protection measure
If you smell gas or suspect a gas leak, go outside immediately and call 911 – this is a serious emergency that needs urgent attention from the gas company.
Boiler diagnostics in a Tempe property start with a full system evaluation — not just the boiler. We check system pressure and its behavior during operation, evaluate the expansion tank pre-charge to determine whether it is functioning correctly, test circulator pump flow, check zone valve operation zone by zone, and inspect the boiler’s heat exchanger and burner assembly. In older Tempe properties with hydronic systems that have been running for decades, we commonly find multiple contributing issues — a partially failed expansion tank that has allowed pressure to climb, combined with a circulator pump bearing that is near the end of its life, and a zone valve that is hanging open instead of controlling properly. Finding and addressing all of the contributing factors in a single service visit is how we prevent a pattern of recurring calls. Boiler repair done correctly is a complete system evaluation, and that is how we approach it in every Tempe property we service.
Boiler Installation
Installing a new boiler in a Tempe property — whether replacing an aging system, upgrading to a higher-efficiency unit, or installing a complete hydronic system in a new construction or major remodel — requires the same whole-system thinking that drives our boiler repair work. The boiler itself is only part of the installation. The pump sizing, zone valve configuration, expansion tank selection, and the integration of all of these components into a working system that heats the space as intended are equally important to the outcome.
Common Problems We Fix
- Aging boiler with declining efficiency and increasing frequency of service calls across recent winter seasons
- Heat exchanger deterioration or cracking in an older boiler making continued operation inadvisable
- Existing boiler that was never correctly sized for the building’s actual heat load
- Complete boiler failure requiring an urgent replacement to restore heat to the property
- Homeowner upgrading to a high-efficiency condensing boiler to reduce operating costs
- New construction project requiring a complete hydronic heating system design and installation
- Radiant floor heating installation in a remodel where the boiler and distribution system must be built from scratch
- Older systems using obsolete components or discontinued equipment that can no longer be properly serviced
- Properties converting from one boiler fuel type or heat distribution method to a more appropriate modern system
If you smell gas or suspect a gas leak, go outside immediately and call 911 – this is a serious emergency that needs urgent attention from the gas company.
Every boiler installation in a Tempe property begins with evaluating the building’s heating load — the amount of heat required to maintain comfort under the coldest conditions this area experiences. For replacement installations, we assess whether the existing boiler was correctly sized and correct it if not. For new system installations, we calculate the load from the structure’s characteristics and design the system around that number. The circulator pump must be correctly sized for the system’s flow requirements and pressure drop. The expansion tank must be properly calculated for the system volume. Zone valves must be selected and wired to provide correct flow control through each heating zone. We commission every installation by filling and purging the system of air, setting the operating pressure, verifying circulator pump performance, confirming zone valve operation, and running the system through heating cycles to verify that each zone reaches design temperatures. A boiler installation completed to this standard in a Tempe property will deliver reliable, efficient performance through many winters of service.
Why Tempe Homeowners Choose Tempe Heating and Air Pros
We Understand Hydronic Systems, Not Just Boilers
The most common failure in boiler service is a technician who diagnoses the boiler in isolation without evaluating the full hydronic loop. A circulator pump that appears to be running may have lost its impeller and is producing no actual flow. An expansion tank that looks intact may have lost its pre-charge and is no longer protecting the system from pressure swings. Zone valves that appear to operate may be partially stuck open, creating flow imbalances across zones. We evaluate the complete system on every boiler call in Tempe because that is the only approach that actually solves the problem rather than patching one symptom while leaving the root cause in place.
We Have Worked in Tempe’s Specialty Boiler Properties
The properties in Tempe that have boilers tend to be the more distinctive ones — older downtown conversions, custom builds in South Tempe, historic properties near the original city center. We have worked in these properties and know the specific challenges they present: older pipe configurations that have been modified multiple times, custom radiant systems with non-standard zone layouts, and buildings where the original installation documentation no longer exists. Navigating these installations requires the willingness to evaluate what is actually there rather than what a standard installation should look like.
We Treat Gas and Combustion Safety as Non-Negotiable
Every boiler service call in Tempe includes inspection of the burner, combustion quality, and venting. For gas-fired boilers, we verify gas pressure, evaluate combustion through visual inspection and temperature measurement, and confirm that the flue venting is clear and properly removing combustion products from the building. A boiler that is firing on a partially blocked flue or at incorrect gas pressure creates both safety hazards and efficiency losses that compound over time. We do not skip these checks on any service visit.
We Provide Honest Assessments of Repair vs Replacement
A boiler that has been running for 25 years in a Tempe property presents a different repair-versus-replacement calculation than one that is 8 years old. We give you a straight assessment based on the system’s actual condition — heat exchanger integrity, efficiency at current operating conditions, and the cost of the repair relative to the system’s expected remaining service life. We will recommend repair when it makes sense and replacement when it does not, and we explain our reasoning clearly in both cases.
We Commission Every New Installation Completely
A boiler installation that is not properly commissioned — meaning the system was not purged of air, the pressure was not correctly set, the circulator pump was not tested under load, and the zone valves were not verified — will underperform and develop problems faster than one that was set up correctly from the start. We complete the commissioning process on every installation in every Tempe property, regardless of how long it takes, because a system that works correctly from day one is what a Tempe homeowner or property owner deserves for the investment they have made.
Our Service Process
Step 1: Contact Us and Describe What Your Boiler System Is Doing
Reach out to Tempe Heating and Air Pros and share what you are experiencing — no heat in certain zones, unusual pressure readings, sounds from the system, pilot or ignition failures, or visible leaks. For installation projects, tell us about the property and what you are trying to accomplish. The more detail you share, the better we can prepare for the service visit.
Step 2: Complete Boiler and Hydronic System Evaluation
We arrive at your Tempe property and evaluate the full hydronic system — not just the boiler. We check pressure, flow, expansion tank function, circulator pump performance, zone valve operation, burner and combustion quality, and venting integrity. For installation projects, we assess the property’s heat load and the existing system configuration that the new installation must work within or replace entirely.
Step 3: Clear Explanation of Findings and Recommendations
We explain what we found in plain terms — what is causing the problem, what needs to be done, and what the expected outcome is. For installation projects, we present the system we recommend with the reasoning behind each component selection. We answer all questions before any work begins, with no pressure and no jargon designed to confuse.
Step 4: Quality Repair or Installation, Fully Verified Before We Leave
We complete the work with correct parts and careful workmanship throughout. For repairs, we verify that the problem is resolved and that the complete system is operating within normal parameters before we leave. For installations, we complete the full commissioning process — air purge, pressure setting, pump verification, zone testing, and multi-cycle heating confirmation — before the job is done.

Professional Boiler Repair and Installation vs DIY Attempts
Hydronic boiler systems present a combination of safety and technical complexity that makes them genuinely inappropriate for DIY repair or installation attempts. We want to be straightforward about the specific reasons, because the risks here are real and consequential.
Gas-fired boilers involve combustion, pressurized gas lines, and flue venting that require specific training, tools, and testing procedures to work on safely. Attempting to adjust a gas valve, inspect a heat exchanger, or modify a venting configuration without proper training and equipment creates risks that can affect the health and safety of everyone in the building. If you smell gas or suspect a gas leak, go outside immediately and call 911 – this is a serious emergency that needs urgent attention from the gas company.
Hydronic systems operate under pressure. A pressure relief valve that is opened or removed without properly depressurizing the system first can cause serious injury. Expansion tanks that are replaced without understanding the system volume and the correct pre-charge pressure will either leave the system underprotected against pressure spikes or overpressurized in ways that stress fittings and seals throughout the loop. Bleeding air from a hydronic system incorrectly can introduce more air into the system or create pressure drops that require multiple correction attempts.
Circulator pump replacement seems straightforward but involves isolating the pump from the system correctly, verifying that the replacement pump matches the original’s flow and head specifications, and restarting the system without introducing air into the loop. A pump that is undersized for the system’s actual flow requirements will produce inadequate heat distribution that can be mistaken for other problems. An oversized pump creates pressure imbalances and noise issues throughout the system.
Boiler installation involves all of these considerations simultaneously, plus the proper sizing of the boiler itself for the building’s heat load. An improperly sized boiler in a Tempe property — particularly in the custom and specialty homes where boilers are most common here — will either short-cycle continuously or fail to meet heating demand on the coldest days. The commissioning process after installation is as important as the installation itself, and it cannot be properly completed without the tools and knowledge to verify every system parameter.

Frequently Asked Questions
What types of boiler systems do you service in Tempe?
We service gas-fired hot water boilers in residential and light commercial applications throughout Tempe, including standard efficiency and high-efficiency condensing boiler systems. We work on systems with radiator distribution, radiant floor heating loops, and combination systems with multiple zone types. We handle both repair of existing systems and complete new installations. Contact us today to discuss your specific system type.
Why is my boiler pressure too high or too low?
System pressure that is consistently outside the normal range — typically 12 to 25 PSI in a residential hot water boiler — usually indicates an expansion tank problem. If the tank has lost its pre-charge, it can no longer buffer the pressure increase that occurs when water heats up, causing pressure spikes. If it is waterlogged, system pressure may drop erratically. A faulty pressure reducing valve can also cause fill issues that affect system pressure. We diagnose the specific cause and address the right component.
Why is my boiler running but some rooms are not getting heat?
Zone-specific heat loss in a Tempe property with hydronic heating almost always points to a zone valve that is not opening properly, air trapped in the distribution pipe serving that zone, or a circulator pump that is not producing adequate flow to that part of the system. We evaluate each zone independently to identify which component is failing and repair it correctly.
What is a pressure relief valve and why does it matter?
The pressure relief valve is a critical safety device that opens to release pressure if the system exceeds its safe operating limit. If this valve is dripping, leaking, or discharging water regularly, the system pressure is reaching its limit too frequently — typically due to an expansion tank failure. A relief valve that has been manually opened or that is dripping constantly may need replacement as well. Never cap or block a pressure relief valve — contact us today if yours is discharging.
Can a boiler near me in Tempe be repaired instead of replaced?
In many cases, yes. Boilers are durable systems and many components can be replaced individually to extend the system’s life significantly. The decision depends on the age of the boiler, the nature of the current failure, and the condition of the heat exchanger. We give you an honest assessment of whether repair or replacement makes more sense for your specific Tempe property and situation.
How do I know if my boiler heat exchanger needs replacement?
Heat exchanger deterioration in a boiler can show up as water leaking from within the boiler cabinet, a significant unexplained drop in system water level, combustion gas contamination in the hydronic water, or visible corrosion during internal inspection. We inspect the heat exchanger as part of every boiler service visit. If we find evidence of heat exchanger failure in a relatively young boiler, replacement of that component may be practical. In an older system, a failed heat exchanger is typically the decision point for full boiler replacement.
What is radiant floor heating and do you install it in Tempe?
Radiant floor heating circulates hot water through tubing embedded in the floor, warming the floor surface and radiating heat upward into the living space. It provides exceptionally even, comfortable heat and is highly valued in custom Tempe homes where it has been specified. We install and service radiant heating systems, including the boiler, circulator pump, manifold, and tubing distribution components. For new installations, we handle the full system design and commissioning.
How often should a boiler be professionally serviced in Tempe?
Annual service is the right cadence for a boiler in a Tempe property, ideally in the fall before the heating season begins. Annual maintenance for a boiler covers burner and combustion inspection, pressure and expansion tank check, circulator pump evaluation, zone valve testing, and heat exchanger condition. Given that Tempe boilers — like all HVAC systems here — sit dormant through a long cooling season, the fall startup inspection catches problems that developed during the off-season before they cause mid-winter failures.
What causes a boiler to make banging or gurgling sounds?
Banging sounds in a hydronic system are most commonly caused by air in the distribution lines — air pockets that disrupt water flow and create pressure fluctuations as the pump tries to move water through them. Gurgling is also typically air-related. Banging in the boiler itself may indicate a phenomenon called kettling, where scale buildup on the heat exchanger causes localized boiling. We purge air from the system correctly and evaluate the heat exchanger condition to address these symptoms at their source.
Do you install high-efficiency condensing boilers in Tempe?
Yes. High-efficiency condensing boilers offer significant operating cost advantages for properties with meaningful heating loads. These systems require specific installation considerations including condensate management and appropriate venting, which we handle as part of every condensing boiler installation in Tempe. We will evaluate whether a condensing boiler is the right fit for your specific property and system configuration.
My Tempe boiler was installed years ago by someone who is no longer available. Can you take over service?
Absolutely. We evaluate systems regardless of who installed them. We will assess the boiler and the full hydronic system, document what we find, and provide honest feedback about its current condition. If records or documentation about the system are not available, we work from what we can observe and test directly. Reach out to us for assistance and we will get your system properly evaluated.
What is the typical lifespan of a boiler in a Tempe property?
A well-maintained boiler in a Tempe property can reasonably be expected to last 20 to 30 years, particularly because our heating season is short and the system does not accumulate run hours as quickly as in colder climates. Cast iron boilers in particular are known for longevity when properly maintained. Annual service and prompt attention to developing issues are the primary factors in achieving the upper end of that lifespan.
