Biermann heats Western Mass homes and buildings across every common system type: gas furnaces, oil furnaces, gas and oil boilers, hot water baseboard, cast iron radiators, hydronic distribution, and heat-pump heating. Our licensed crew services both residential equipment in single-family homes and commercial-grade boilers in apartment complexes, office buildings, and municipal facilities.
Service-first is the operating philosophy. Keeping an existing furnace or boiler running safely and reliably is the core work, and replacement and new construction follow naturally from there. We run the full phrase, Plumbing, Heating & HVAC, under one roof with one crew, so the plumber who ran your gas line is the same team that sized your boiler.
Coverage is all of Western Massachusetts (Hampden, Hampshire, and Berkshire counties) plus Enfield and Suffield, Connecticut. Forty-two years in business, MA Master Plumber #16160 and CT Master Plumber #PLM.0288365-P1, fully licensed and insured, with a 1-year labor warranty on every installation. Free consultations for service planning; a flat $65 fee applies to formal project estimates.
Fast response for existing customers. New callers served during normal business hours (Mon-Fri 7am-3pm).

Four buckets that cover almost every heating call we take. If your situation doesn’t fit one of these neatly, call us, that’s what consults are for.
A furnace moves heated air through ductwork to the rooms in your home. When a furnace stops working, the usual suspects are a failed igniter or flame sensor, a clogged filter choking the blower, a bad inducer motor, a draft-pressure switch stuck open, or a blower motor on its way out. We diagnose, source the part, and get you warm again, on residential gas furnaces and light-commercial gas furnaces in small offices, retail, and multi-res common areas.
Oil-fired furnaces are still common across the Pioneer Valley and Berkshires, and we still service them (nozzle replacement, pump and filter changes, burner tune-ups, tank and line work). On replacement decisions, our rule is simple: if the repair is more than half the cost of a new unit and your furnace is past its mid-life, start the replacement conversation. Right-sizing matters more than brand; an oversized furnace short-cycles and wears itself out.
Important note: Biermann does not self-perform sheetmetal and ductwork. We coordinate the full forced-air system and partner with trusted sheetmetal specialists on duct fabrication, modifications, and ties-ins. Fall tune-ups are the cheapest way to catch problems before a January no-heat call.
A boiler heats water and moves it through baseboard, cast iron radiators, or in-floor loops. We service both cast iron boilers in older Western MA homes and high-efficiency condensing boilers in newer buildings and retrofits. Common failure points we see all winter: circulator pumps that seize, zone valves that stick, expansion tanks that waterlog, air in the lines making baseboard bang, and heat exchangers at end of life. Many older homes still have original cast iron radiators, and we keep those systems running when others won\’t.
On commercial and multi-residential properties, boiler work is a core part of the business: apartment buildings, condo associations, offices, banks, and dental practices where the boiler also feeds domestic hot water through indirect tanks or tankless coils. We handle mixing valves, anti-scald controls, and near-boiler piping as part of the system. For public schools and municipal boiler projects, see municipal & prevailing wage.
On replacement, we install and stock Crown, NTI, HTP, and Lochinvar. For product specs and tank options on boiler-fed domestic hot water, see water heaters & boilers.
Air-source heat pumps and ductless mini-splits have come a long way for cold-climate heating. Cold-climate-rated units now run efficiently down well below zero, which covers the bulk of Western MA winters. Berkshire homes see real single-digit and sub-zero stretches, though, so we plan accordingly. For most homes we recommend a hybrid: the heat pump carries the load most of the year, and your existing gas boiler, oil furnace, or a factory-integrated electric strip kicks in on the coldest nights.
Our framing is neutral. Heat pumps are a great fit for some homes and buildings and a poor fit for others. It depends on electrical capacity, existing infrastructure, the room layout, and what you already own. We\’ll walk your home and lay out the real options without pushing any single fuel type.
For full install scope, sizing, indoor and outdoor unit selection, and commissioning, see heat pump installation & service. For A/C and cooling-mode work more broadly, see HVAC and A/C installation & replacement.
Fall tune-ups are the lowest-cost, highest-leverage heating service we offer. A proper furnace or boiler tune-up includes combustion analysis, limit and flame-safety checks, a venting inspection for CO risk, filter replacement where a filter is on-site, and a circulator and zone-valve check on hydronic systems. We catch the small failures (a weak flame sensor, a stuck zone valve, a failing inducer) before they become a 2am no-heat call in January. Tune-ups are available as a single visit or bundled into a year-round plan with a spring cooling visit at HVAC maintenance plans.
24/7 emergency heating service is available to existing customers only. That policy lets us respond fast for homes and buildings we already know, with our techs and our history on that system. New callers are served during normal business hours (Mon-Fri 7am-3pm). The simplest way to become a customer ahead of winter is to schedule a tune-up now.
Call (413) 547-2970 for no-heat calls, boiler lockouts, burner failures, or CO alarms. If your issue is a leak rather than a heat problem, see emergency plumbing repair.
Four things we bring to every heating job, from a single-family boiler swap to an occupied-building furnace run.
Keeping your home or property running safely is our core business. We build long-term relationships, not one-off transactions.
Two trades, one dedicated crew. From an emergency call at your house to a ground-up commercial build, you never juggle multiple contractors.
Four decades of working in active homes, apartment complexes, dental offices, and banks. Clean worksites, low noise, and respect for your space.
Prevailing wage, certified payrolls, public bidding, and strict documentation. Most small shops won't touch public projects. We welcome them.
Existing Biermann customers get first priority for same-day response on no-heat calls, and our dispatch team will triage your call when it comes in. New callers are scheduled as quickly as possible during normal business hours (Mon-Fri 7am-3pm). Before you call, check three things: is the thermostat set to heat with fresh batteries, is the furnace switch in the utility room turned on, and is the filter so dirty it’s choking airflow. If none of that solves it, call us at (413) 547-2970 and we’ll get you on the schedule.
Typical service life runs 15 to 20 years for a gas furnace, 20 to 30 years for an oil-fired furnace with good maintenance, 15 to 20 years for a high-efficiency condensing boiler, and 25 to 40 years for an older cast iron boiler. Our rule of thumb: if a repair costs more than half the price of replacement and the unit is past its mid-life, you’re usually better off replacing. We offer free consultations to walk your system, and formal written estimates are a flat $65.
It depends on what you already have. Homes with natural gas at the street and a newer boiler or furnace usually stay gas. Homes with an old oil tank facing replacement anyway sometimes swap to gas, propane, or a cold-climate heat pump. In the Berkshires and colder parts of the Pioneer Valley, we often recommend a hybrid setup: a cold-climate heat pump for most of the year, with your existing boiler or furnace as backup on the deep-cold days. We’ll walk your home, look at your infrastructure and budget, and lay out the real options.
24/7 emergency heating service is available to existing customers only. That policy lets us respond fast for the homes and buildings we already know. New callers are served during normal business hours (Mon-Fri 7am-3pm). If you’d like to become a customer ahead of winter, the simplest path is a fall tune-up visit or a maintenance plan; after that your property is in the rotation for after-hours response.
Yes. Many contractors won’t touch older hot-water and cast iron radiator systems, but we work on them all the time. Common issues we fix include banging and clanking from air trapped in the lines, leaking valves at the radiator, failed or noisy circulator pumps, and rusted zone valves. Cast iron systems heat beautifully and often have decades of life left if the near-boiler piping and controls are kept in shape. Worth keeping running, and worth keeping running right.
Yes. Gas piping is part of our licensed scope. We install black iron and CSST, size lines correctly for high-efficiency equipment (undersized lines are a common reason new condensing boilers short-cycle), pressure-test, and pull the required permits. If you’re adding a new heating appliance, a unit heater, or a generator feed, see gas line installation & repair for the full scope.
We don’t self-perform sheetmetal and ductwork. We coordinate the full heating system, specify the ducted equipment, and partner with trusted sheetmetal specialists for duct fabrication, modifications, and tie-ins. One project, one point of contact, and the ductwork gets done right by people who do nothing else.
Combustion analysis on gas and oil equipment, safety-control check (limit switches, flame sensor, pressure switch, rollout switches), venting and CO-risk inspection, filter replacement if a filter is on-site, circulator and zone-valve check on hydronic and boiler systems, and a thermostat calibration and operation check. Available as a single visit or bundled into a year-round plan with a spring cooling visit. See HVAC maintenance plans for plan details.
Yes. Multi-residential and commercial boiler work is a core part of what we do, from replacement in occupied apartment buildings to maintenance contracts for office buildings, condo associations, and healthcare facilities. We’re also experienced with prevailing-wage public boiler projects. See property services for ongoing service programs and municipal & prevailing wage for public work.
