Complete Boiler and Hydronic Heating Service

Scott HVAC and Home Service provides comprehensive maintenance, diagnostics, repair, replacement and installation for gas-fired boilers and hydronic heating systems. We work on traditional cast-iron boilers, modern high-efficiency condensing boilers, combination heating and domestic-hot-water systems, multi-zone baseboard systems, radiant heating and commercial hydronic applications.

Whether a boiler needs routine maintenance, an accurate diagnosis, a modern control upgrade or complete replacement, our goal is to restore safe, dependable and efficient operation while protecting the entire heating system—not only the boiler itself.

High-Efficiency Gas Boiler Installation

A successful boiler replacement begins with proper system evaluation. We consider the building’s heating load, radiation, zoning, water temperature requirements, domestic hot-water demand, venting route, combustion-air requirements, gas supply, condensate disposal and existing near-boiler piping before recommending equipment.

Our installation scope may include removal and responsible disposal of the existing equipment, new near-boiler piping, primary-secondary piping or hydraulic separation when required, pumps and zone controls, gas-piping modifications, venting and combustion-air connections, condensate drainage and neutralization, electrical and thermostat connections, system flushing, purging, startup, combustion analysis and final commissioning.

We install and service equipment from leading manufacturers, including Lochinvar, Navien, Weil-McLain, Viessmann, NTI, Triangle Tube, Burnham/U.S. Boiler and other respected boiler brands. Equipment is selected for the needs of the property rather than by brand name alone.

Taco High-Efficiency Hydronic Upgrades

The boiler is only one part of a hydronic heating system. Outdated circulators, failing zone valves or poorly configured controls can reduce comfort and efficiency even when the boiler is operating correctly. Scott HVAC and Home Service installs and upgrades Taco hydronic components designed to improve circulation, zoning, control and serviceability.

Hydronic System Improvements

We can evaluate the complete system and recommend corrections when the boiler room contains outdated, unreliable or inefficient components. Improvements may include air separators, expansion tanks, pressure-reducing valves, backflow preventers, isolation valves, purging stations, circulators, zone controls, outdoor-reset controls, low-water cutoffs, condensate neutralizers and piping corrections.

Proper water flow, air removal, pressure control and zoning are essential to dependable hydronic heating. Correcting these conditions can improve comfort, reduce noise and make future maintenance easier.

Professional Startup and Commissioning

Every qualifying installation is started, tested and commissioned. We verify system pressure, purge air from the heating zones, confirm circulator and zone-valve operation, test safety controls, check venting and condensate drainage, perform combustion analysis, review control settings and confirm proper operation before completion.

Manufacturer warranties apply according to the manufacturer’s terms and registration requirements. Qualifying installations are also supported by our three-year workmanship warranty covering installation-related defects under normal operating conditions.

Frequently Asked Boiler Questions

How often should a gas boiler be maintained?

Gas boilers should generally receive professional maintenance once each year, ideally before the heating season. Annual service helps verify combustion, venting, safety controls, water pressure, pumps, valves and overall operating condition.

Can an older boiler system be upgraded without replacing the boiler?

In many cases, yes. Replacing inefficient circulators, unreliable zone valves, outdated relays or poorly arranged controls can improve system reliability and control. The existing boiler and distribution system must be evaluated to determine which upgrades are appropriate.

When should a boiler be replaced instead of repaired?

Replacement may be appropriate when the heat exchanger is compromised, repair costs are excessive, critical parts are unavailable, breakdowns are becoming frequent or the existing equipment no longer fits the property’s heating and efficiency goals. We explain the condition of the system and provide practical repair-versus-replacement guidance.
