8 Best Heating contractor in Milwaukee for SameDay Service

J.M. Brennan, Inc. is a mechanical contracting firm headquartered at 2101 W St Paul Ave in Milwaukee's Menomonee Valley, combining plumbing with HVAC contracting, fire protection, and industrial piping. Its listed scope covers boilers, chillers, air handling units, exhausts and ventilators, sanitary sewers, food-grade and industrial-gas piping, compressed air systems, and sheet metal work, with design and engineering staff alongside steam and refrigeration fitters. Review and business-record themes point to a commercial clientele rather than residential service. Reviewers describe rooftop unit service, office build-outs, kitchen and conference-room additions, and round-the-clock repair and maintenance arrangements. Named staff include Kris for service coordination and Matt and John on project work, with reviewers characterizing the company as thorough, responsive, and a long-term partner for construction, maintenance, and emergency response. The business is listed as open 24 hours, positioning emergency repair as a core offering. This is a fit for facility managers, property owners, and general contractors needing a mechanical contractor that handles plumbing, HVAC, and fire protection under one contract. The Menomonee Valley location suits southeastern Wisconsin commercial sites, and the firm's service-and-repair positioning makes it relevant for buildings that need continuous mechanical coverage rather than a single residential plumber.

O & W Heating and Cooling and Furnace, boiler, water heater install & repair is a Milwaukee heating and plumbing contractor at 4379 S Howell Ave in the Town of Lake neighborhood, specializing in gas furnaces, boilers, air conditioners, heat pumps, and water heaters including tankless units from brands like Navien, Bradford White, Bryant, and Lennox. It keeps unusually long hours — 6 AM to 9 PM weekdays and Saturdays, to 9:30 PM Sundays — and provides emergency service even on weekends, positioning itself around availability when other shops are closed. The review record centers on owner-operator Omer, who is repeatedly credited with answering initial calls within minutes, arriving at homes within the hour, and completing full water heater replacements within a day when other services quoted multi-day waits. Customers describe him explaining each step, providing temporary space heaters during breakdowns, and delivering fair pricing. Reviewers also note quick responses to after-hours online requests, including a storm-related water heater call answered within half an hour. This is a fit for south-side Milwaukee homeowners whose furnace or water heater fails on a weekend and cannot wait until Monday, and for anyone who wants the same technician from diagnosis through installation. The tankless and heat-pump expertise suits buyers modernizing older heating systems. Expectation-setting is easy here: the record is essentially one person's responsiveness, so service quality tracks the owner-operator directly.

Heiden Plumbing, Heating & Cooling is a dual-trade contractor at 1100 W Bruce St in Milwaukee's Walker's Point neighborhood, covering plumbing, sewer and water, and HVAC. On the plumbing side its specialties include sewer line clearing and camera inspection, sewer pipe relining, water heater installation and repair, and emergency repairs; the HVAC side handles furnace outages, AC repair, and replacements. The company serves the Milwaukee area with emergency service availability alongside weekday office hours. The review record is richest on sewer work: one customer describes a line two other companies couldn't fully clear being reopened when Heiden found roots rather than the collapse they had feared, saving a full lateral replacement; another describes a sewer relining job on an old pipe completed politely and promptly; a third recounts a significant line repair dug eight feet down in minus-twenty weather. Named technicians include Adam, Jason, Andy, Scott, Gary, and Jared. A balanced note: a few reviews mention communication or scheduling snags, including one customer who found a water heater consultation dismissive. This is a fit for homeowners facing scary sewer-line diagnoses who want a second opinion before committing to a full replacement, and for anyone needing a sewer relining on an older Milwaukee home. The flood-response story — a crew working daily on a basement with six feet of water — marks it for disaster-recovery calls. HVAC customers get the same shop for furnace and AC work, which suits anyone who prefers one contractor for the whole house.

Austin Plumbing, Heating, Air & Electric — known as Team Austin — is a southeast Wisconsin multi-trade contractor with locations in Hartland, Germantown, and Milwaukee at 11414 W Park Pl #202. Its trades span plumbing, heating, cooling, electrical, and duct cleaning: water heater replacement, furnace repair and installation, leak repairs, drain and clog clearing, fixture work, sump systems, water softeners, and full-home duct cleaning. The company serves Lake Country, Waukesha County, Washington County, Milwaukee County, and surrounding communities, with emergency service availability. The review record emphasizes honesty over upselling: the company states its technicians earn the same on a small fix or a big repipe, so no one nudges the scope upward. Customers describe techs like Don tracing a water leak to two toilet tank valves rather than selling new toilets, Pete explaining water heater options step by step, and Todd catching dangerous carbon monoxide leaks during a tune-up. Recurring themes include punctual arrivals, knowledgeable explanations, clean work sites, annual maintenance plans with reminders, and same-week installations. A water heater replacement reportedly went from call to hot water in under six hours. This is a fit for homeowners who want one shop covering plumbing, heating, cooling, and electrical, and for anyone wary of sales pressure: the no-salespeople positioning is the company's defining claim. The duct cleaning and maintenance-plan offerings suit buyers of whole-home air quality. Customers in higher-end homes get a record of techs presenting honest options instead of assuming a bigger budget.

Malone's Plumbing & Heating Inc is a Milwaukee contractor at 6515 N 40th St in the Graceland area covering plumbing, heating, and air conditioning, with bathroom remodeling and furnace repair also in the mix. Its listed services span central air installation, duct cleaning, drain cleaning, drain repair, and emergency plumbing, alongside residential plumbing work. The business keeps weekday hours, Monday through Friday, 8 a.m. to 4:30 p.m. Customer commentary clusters on water heaters and furnaces: one customer describes technicians Greg and Nick replacing a failed water heater right away, arriving on time and verifying the system was leak-free before leaving; another praises Vince and Nick for explaining a water heater install step by step and cleaning up fully. A long-time customer reports using the company for plumbing, boiler, and air conditioning issues, citing clear communication about arrival times. Next-day availability comes up repeatedly in reviews. This is a fit for a Milwaukee homeowner who wants one contractor covering both plumbing and HVAC — a furnace replacement, a failed water heater, a drain backup — without juggling separate trades. The weekday-only schedule suits planned replacements and repairs rather than late-night emergencies. For anyone comparing quotes on a water heater or furnace, the review pattern points to careful, communicative installers.

Uttke Heating, Cooling & Plumbing is a heating, cooling, and plumbing contractor at 4209 S Howell Ave on Milwaukee's south side, serving the metro area with both HVAC and plumbing work. Its listed scope includes furnace and air-conditioner installation and replacement, indoor air quality products, and plumbing repairs such as fixture and faucet fixes, with the business describing itself as an HVAC service shop that has expanded into plumbing. Review themes are consistently strong on responsiveness and communication. Customers name owner Jen for fast, clear office coordination and Mark, Tristan, Noah, and TJ for field work, describing prompt arrivals, itemized quotes, and crews that leave work areas clean. A late-Friday shower-faucet emergency got a technician on site within 20 minutes, and several customers report replacing furnaces and air conditioners after comparing quotes, describing Uttke's pricing as competitive with solid warranty terms. One customer calls pricing a tad high but worth the peace of mind. This is a fit for south-side Milwaukee and metro-area homeowners who want one company covering both heating and cooling and plumbing, especially for time-sensitive failures like a faucet that will not shut off or a failed furnace during a cold snap. The pattern of same-day emergency response and thorough quote explanations suits owners comparing options before a major HVAC or plumbing investment.

Burkhardt Heating, Cooling, Plumbing & Electric is a multi-trade contractor at 8232 N Teutonia Ave in Milwaukee, covering HVAC, plumbing, and electrical across Greater Milwaukee. Its HVAC work includes furnace and air conditioner installation and replacement, combi boilers, duct cleaning, air quality solutions, and ductless systems; the plumbing side handles garbage disposals, leaks, clogs, water heater replacement, and camera drain inspection; the electrical side takes on service calls and installations. The company advertises same-day service on most calls and 24/7 emergency dispatch for no-heat, burst-pipe, and electrical emergencies. The review record is volume-heavy and mostly positive: a furnace replacement scheduled the day after the call and installed the next, a combi boiler installed over three days with thorough communication, and a same-day water heater replacement described as more affordable than competitors. Named techs include Connor, Chiko, Dan, Tae, Gerson, Jim, Sher, Derek, Kennedy, Jake, Shawn, and Billy. Recurring themes include quick scheduling, flat-rate pricing stated before work begins, trucks stocked for one-visit repairs, and cleanup that leaves no mess behind. A balanced note: like any large operation, occasional reviews cite missed windows, so confirming the arrival slot matters. This is a fit for Milwaukee homeowners who want a single contractor for a furnace, water heater, and electrical panel across one visit schedule, and for landlords needing fast no-heat response in winter. The combi boiler and ductless offerings suit homes modernizing heating without full ductwork. Customers comparing large install quotes will find the day-after-scheduling pattern the clearest indicator of capacity.

West Allis Heating, Cooling, Plumbing, and Electrical is a multi-trade contractor at 201 S Hawley Ct in Milwaukee, serving Milwaukee and surrounding areas across heating, cooling, plumbing, drain cleaning, and electrical work. The company offers customized HVAC and plumbing services to homes and businesses with 24/7 availability, including furnace and air conditioner service, water heater installation, drain clearing, and repairs. The plumbing side handles the full residential range from leaks and fixtures to sewer and drain work. The review record is large and largely positive: a new water heater installed before the morning was over, installers arriving early and leaving work areas clean, and a drain specialist named Jason praised for explaining everything and quoting before starting. Reviews frequently cite professionalism, friendliness, and knowledgeable staff who stand behind their work and address issues promptly. For balance, some recent BBB reviews criticize diagnostic recommendations — including expensive heat-exchanger replacement quotes — suggesting customers get a second opinion on major equipment calls. This is a fit for Milwaukee-area homeowners who want one contractor for furnace, water heater, and drain needs with round-the-clock dispatch, and for landlords valuing fast emergency response. The drain-cleaning emphasis suits properties with recurring backups. Buyers comparing quotes on big-ticket HVAC replacements should weigh the positive installation record against the critical diagnostic reviews and confirm scope before authorizing equipment swaps.
