What’s Included in Professional HVAC Plumbing Maintenance

Comprehensive HVAC plumbing maintenance from Burkhardt Heating & Cooling is designed to keep your systems running safely, efficiently, and reliably through Milwaukee’s demanding seasons. During a typical maintenance visit, our technicians inspect and clean the condensate drain pan and lines, verify proper traps and venting, and ensure that all drain piping is free of algae, sludge, and debris that can cause clogs and overflow. We also examine boiler and hydronic piping for corrosion, leaks, air accumulation, and proper insulation, making adjustments and minor repairs before they turn into costly emergencies.

Our maintenance service also includes checking water pressure and flow rates in hydronic heating systems, inspecting zone valves and circulator pumps, and confirming that expansion tanks and pressure relief valves are functioning correctly. For homes with radiant floor heating, we verify loop balancing, manifold integrity, and the condition of mixing valves to ensure even, comfortable heat. If your home uses a tankless or traditional water heater as part of your comfort system, we check for scale buildup, test temperature settings, and confirm proper venting and condensate removal. Scheduling regular HVAC plumbing maintenance with our Milwaukee team helps you avoid leaks, water damage, and efficiency loss while extending the life of your equipment.

Condensate Drain Lines, Leaks, and AC Drain Issues

In our climate, high-efficiency furnaces, air handlers, and air conditioners generate significant condensate, making proper drain line maintenance essential. As a general rule, condensate drain lines should be cleaned at least once per year, ideally at the start of the cooling season in Milwaukee. In homes with high humidity or where past clogging has occurred, we often recommend semiannual cleaning to prevent algae, mold, and sediment from building up in the line. During this service, our technicians flush the line, treat it with appropriate cleaning agents, and ensure that the condensate pump, if present, is operating correctly.

If you notice water leaking from your furnace or air handler, the most common causes are a clogged condensate drain line, a cracked or misaligned drain pan, improper slope of the drain piping, or a failed condensate pump. In high-efficiency furnaces, leaks can also result from improperly drained flue gases or blocked PVC venting. Because these components are integrated with your HVAC system and involve both plumbing and electrical controls, you typically need an HVAC technician rather than a general plumber for AC drain issues. Our team at Burkhardt Heating & Cooling is trained to diagnose both the mechanical and refrigerant side of your equipment, ensuring that the root cause of the leak is resolved, not just temporarily cleared.

When in doubt, contacting a dedicated HVAC contractor in Milwaukee ensures that your warranty stays intact and that system performance is properly evaluated. If you are experiencing repeat condensate drain clogs, nuisance float switch trips, or water damage around your indoor unit, schedule an inspection so we can recommend lasting improvements such as drain line rerouting, trap redesign, or upgraded pumps.

Hydronic Heating, Low Water Pressure, and Frozen Pipe Prevention

Hydronic heating systems rely on properly balanced water pressure and flow to deliver stable, even comfort to your home. Low water pressure in hydronic heating systems can be caused by air trapped in the lines, failing or undersized circulator pumps, partially closed isolation or balancing valves, clogged strainers or filters, or scaling inside older pipes and heat exchangers. In Milwaukee homes with older boilers, mineral buildup from hard water is a frequent contributor to restricted flow and noisy operation. Our technicians diagnose these issues by checking system pressure, bleeding radiators or manifolds, testing pump performance, and inspecting expansion tanks and pressure-reducing valves.

Wisconsin winters make frozen pipes in HVAC and boiler lines a serious concern, especially in poorly insulated areas like basements, attics, garages, or exterior walls. To prevent frozen and burst hydronic lines, we recommend proper pipe insulation, sealing air leaks around penetrations, and maintaining appropriate thermostat settings even when you are away from home. In some systems, using the correct glycol antifreeze solution is essential, especially for radiant floor loops or hydronic lines that pass through semi-conditioned spaces. Our team can assess your system, recommend the right level of freeze protection, and ensure all components are rated and set up correctly for Milwaukee’s subzero temperatures.

If you hear banging, gurgling, or notice cold spots in your radiators or radiant floor zones, it may indicate circulation and pressure problems that could worsen in freezing weather. Scheduling a preventive hydronic heating inspection with Burkhardt Heating & Cooling before winter is the most effective way to address pressure issues, protect your pipes, and maintain consistent comfort throughout your home.

Boiler Plumbing: Repair vs. Replacement Decisions

When your boiler or its associated plumbing begins to show signs of age—repeated leaks at fittings, corroded pipes, inconsistent heating, or rising energy bills—it is natural to wonder whether to repair or replace. In many Milwaukee homes, older boilers and piping were installed decades ago and may no longer meet modern efficiency expectations or safety codes. Generally, if your boiler is more than 15–20 years old, requires frequent repairs, or has major issues like a cracked heat exchanger or severely corroded distribution piping, replacement is often the more cost-effective, long-term solution.

On the other hand, isolated leaks at valves or joints, failing circulator pumps, air vent issues, or minor control problems can typically be repaired economically, especially when the boiler itself is still in sound condition. Our technicians will evaluate not only the boiler but also the plumbing network—supply and return lines, manifolds, expansion tanks, and zone controls—to determine whether targeted repairs can restore reliable operation. We also consider energy efficiency gains from new high-efficiency boilers, which can significantly reduce fuel use for Milwaukee homeowners.

During a consultation, we provide clear recommendations, cost comparisons, and expected lifespans so you can make an informed choice between repair and replacement. If a full system upgrade is the better path, we also review options for integrating new boiler equipment with existing radiant floor heating, baseboard radiators, or indirect water heaters. To discuss the best approach for your boiler plumbing, contact Burkhardt Heating & Cooling and schedule an in-home assessment.

Water Heaters, Tankless Systems, and Your HVAC Setup

Water heaters play an increasingly important role in modern HVAC designs, especially in homes that use indirect water heating, radiant floor systems, or combination boiler-water heater setups. Many homeowners in Milwaukee ask whether tankless water heaters are compatible with existing HVAC systems. In many cases they are, but proper sizing, piping, and venting are crucial. Tankless units can support domestic hot water and some hydronic applications, but they must be selected and installed with attention to flow rates, temperature rise, and distribution design. Our technicians can evaluate your current furnace, boiler, or radiant system and determine whether a tankless solution is appropriate or if a dedicated boiler or indirect tank would perform better.

Determining what size water heater you need for your home HVAC setup depends on your household hot water demand, the number of fixtures and bathrooms, the presence of large tubs or multi-head showers, and whether the water heater will support any space heating loads. For example, a family in Milwaukee with two bathrooms and a hydronic heating loop will typically require a higher-capacity tank or a higher-BTU tankless unit than a household using hot water only for fixtures. We perform detailed load calculations, considering peak demand times and your preferred usage patterns, to recommend a properly sized system that avoids both shortages and unnecessary energy waste.

Properly integrated plumbing design also has a direct impact on the efficiency of radiant floor heating
