Biozura Heating and Air Project Gallery
The gallery below documents installations and major service work completed across Hartford County between 2022 and 2026. Each entry includes the equipment installed, the building it went into, and the technical reason the job mattered — not just glamour shots of new condensers on level pads. Customer addresses are anonymized to the nearest cross-street or neighborhood. Equipment model numbers are listed because they document what was actually installed, not what was promised in the proposal.
Steam Boiler Replacements
Roughly 38% of Hartford County’s owner-occupied housing predates 1960, and the majority of those homes still operate on original or first-replacement cast iron steam systems. Steam boiler work is the deepest specialty in the Biozura service catalog because it is the work most generalist contractors get wrong — EDR mismatched to boiler output, pressure dialed to 8 PSI when it should be 0.5, skim ports never opened, near-boiler piping installed without proper steam main rise and Hartford loop.
1923 West Hartford Colonial — Sedgwick Road area
Replaced 1962 Burnham IN-7 with a Burnham IN-6 sized to measured EDR of 412 sq ft (versus the homeowner’s previous estimate of 575 sq ft based on square footage). New boiler net steam output: 99,000 BTU/hr at 215°F. Original 14 cast iron column radiators retained, all valves re-packed, three thermostatic radiator valves added on the second floor to balance heat distribution. Hartford loop installed at the correct height; near-boiler piping rebuilt with two 24-inch riser sections per ASHRAE residential steam practice. Operating pressure set to 1.5 PSI. First-season gas consumption down 31% versus the previous winter on the oversized unit.
1908 Hartford brownstone — West End
Two-pipe vapor steam system, original 1908 cast iron radiators with brass air vents (preserved). Replaced corroded 1987 Weil-McLain EG-65 with a Weil-McLain EG-50 sized to 326 sq ft EDR. The job required threading a 30-inch-wide boiler down a 28-inch-wide basement bulkhead opening using a stair dolly and three-man lift. New Hoffman Differential Loop installed (the original orifice fittings on every radiator are unobtainable; the differential loop simulates the same flow restriction at the system header). Pressuretrol set to 6 oz cut-in, 16 oz differential. The homeowner kept her original 1908 air vents.
1947 Bloomfield Cape — near Wintonbury Avenue
One-pipe steam, eight cast iron tube radiators, system installed in original construction. Replaced failing 1994 Crown Aruba 4 with a Burnham IN-4 at 65,000 BTU/hr net steam (radiator EDR measured at 168 sq ft). Cleaned 50 years of accumulated mud and oxidation from the steam mains using a five-cycle steam blowdown procedure before the new boiler was fired. Re-pitched two main runs to drain back to the boiler at minimum 1 inch per 20 feet. Boiler chemistry treated with Hydrolevel boiler conditioner; pH monitored over the first 90 days to settle into the 9.5–11 range.
Furnace and Air Handler Installations
1998 Farmington Colonial — Devonwood subdivision
Replaced original 1998 Carrier 58CTA 80% AFUE furnace with a Carrier 59MN7 96% AFUE modulating gas furnace paired with a Carrier 24ANB7 17-SEER2 condenser. Manual J performed cold revealed an actual heating design load of 62,000 BTU/hr, versus the existing 100,000 BTU/hr furnace. New furnace sized at 80,000 BTU/hr (smallest available modulating unit from Carrier’s Infinity line). Static pressure measured at 0.83″ WC on the original ductwork — over spec for the ECM blower — corrected by adding a return drop and resizing one supply trunk. Final static pressure: 0.41″ WC.
1957 West Hartford ranch — near Mountain Road
Original 1992 Lennox G24 60,000 BTU/hr atmospheric furnace replaced with a Rheem R96V 70,000 BTU/hr two-stage condensing unit. Sidewall PVC venting installed through the existing oil tank chimney chase per CT 2022 IMC amendments, with combustion air drawn from outside (sealed combustion). The original masonry chimney lined with a 3-inch stainless steel B-vent for the water heater — required because removing the furnace from the chimney drew the chimney out of code for water heater operation per NFPA 54 Section 12.
Heat Pump and Ductless Mini-Split Retrofits
1925 Hartford bungalow — South West neighborhood
Mitsubishi MUZ-FS18NA Hyper-Heat outdoor unit paired with four MSZ-FS09NA wall-mounted indoor heads. Total connected capacity: 36,000 BTU/hr nominal, 25,400 BTU/hr at the building’s 4°F ASHRAE design temperature per NEEP CCHP database. Existing oil-fired boiler retained as backup. Refrigerant lines run through interior chase rather than exterior wall to preserve original Hartford bungalow siding. Eversource heat pump rebate filed at $9,000 for partial electrification; paperwork submitted within 48 hours of equipment ship date.
2019 Avon new construction — off Country Club Road
Whole-house Daikin Aurora cold-climate heat pump system. Outdoor unit: RXTQ48TAVJUA, 48,000 BTU/hr nominal, paired with FTQ42TBVJUA indoor air handler. Sized to Manual J calculated load of 33,000 BTU/hr at 4°F — 1.45x oversized at design temperature, sized for the 50°F mean January temperature where the variable-capacity modulation provides best efficiency. Backup electric resistance heat (15 kW) installed for emergency redundancy. Annual heating cost projection (based on Eversource Rate R electric and CNG natural gas comparison): heat pump $1,840, gas furnace $1,620. The customer chose the heat pump for refrigerant-only operation and lower carbon profile.
1953 Newington Cape — ductless retrofit
Mitsubishi MUZ-FH12NA single-zone wall-mount serving an addition built in 2014 that was originally heated by a baseboard electric resistance loop running at $0.32/kWh on Eversource Rate R. Pre-retrofit annual heating cost for the 320 sq ft addition: $890. Post-retrofit cost (Mitsubishi at COP 2.8 at design): $310. Payback period: 2.4 years on equipment-and-install cost of $3,400 after Eversource $1,500 partial-electrification rebate.
Commercial Rooftop Unit Installations
Farmington Avenue insurance brokerage — West Hartford
Replaced two end-of-life 2008 Trane Voyager YCD060 6-ton 13-SEER package units with two Carrier 48HC07 7-ton 14-SEER units. New units include economizer for outdoor air ventilation sized to ASHRAE 62.1 for the building’s 28-person occupant load (380 CFM outdoor air per unit). Demand-controlled ventilation enabled via CO&sub2; sensors. July post-install utility tracking: cooling-season kWh down 26.4% versus same period prior year.
South Main Street medical office — West Hartford
Three Carrier 48HC04 4-ton package units replacing three 17-year-old Lennox Strategos. Each unit serves a different zoning need: front office, exam rooms, lab. Installed Honeywell T7350 commercial thermostats with after-hours setback programming. Office reported elimination of the chronic 4 p.m. temperature complaints from the south-facing exam rooms that had plagued the prior system.
Indoor Air Quality Installations
HEPA bypass — Bishops Corner allergen project
Aprilaire 5000 electronic air cleaner paired with a Lennox PCO20-28-1 bypass HEPA filter on a 1996 ranch where two of three occupants documented FEV1 readings below 80% of predicted (severe asthma). The Aprilaire 5000 handles 92% of particles 1.0 micron and larger; the HEPA bypass catches 99.97% of particles down to 0.3 microns including PM2.5 from Bradley International Airport flight paths to the east. Total system static added: 0.18″ WC.
Whole-home humidification — West Hartford Colonial
Aprilaire 800 steam humidifier installed on a 1928 Colonial in Sunset Farm with original plaster walls that were cracking during winter relative humidity drops to 12–15%. The Aprilaire 800 generates up to 34.6 gallons of humidification per day at 240V single-phase; sized to maintain 35–40% RH at outdoor design temperature. Water hardness from the MDC supply tested at 9 grains per gallon (relatively moderate by national standards but enough to require canister replacement every 18–22 months).
Frequently Asked Questions
- Can I see photos of jobs Biozura has done in my specific neighborhood?
- The gallery above documents work across West Hartford, Hartford, Bloomfield, Newington, Farmington, and Avon. For projects in other Hartford County towns — New Britain, Wethersfield, East Hartford, Windsor, Simsbury — or for specific equipment types not shown, call the office at (860) 955-4428 and ask for references in your area. Most homeowners are willing to share their experience by phone or email; some allow site visits during routine maintenance.
- Why are most photos of steam boiler replacements rather than newer equipment?
- Steam boiler work is the technical specialty most differentiating in the Hartford market because roughly 38% of Hartford County’s owner-occupied housing predates 1960, and most of those homes still operate on cast iron steam. The work is hard to do right — EDR-based sizing, Hartford loop near-boiler piping, correct pressuretrol settings, system cleaning — and the photos document techniques most generalist contractors don’t execute. Furnace and AC photos are visually less differentiated because most installations look broadly similar; the difference is in the static pressure measurements, line set brazing quality, and refrigerant pressure verification that don’t photograph well.
- Do you guarantee the same equipment shown in the gallery for new quotes?
- No. Equipment selection on every new quote is driven by load calculation (ACCA Manual J), available physical space, fuel source, and homeowner budget — not by what looks similar to a previous project. A 1923 Sunset Farm Colonial might receive a Burnham IN-6 steam boiler; a 1957 ranch on Mountain Road might receive a Rheem R96V condensing furnace. The gallery shows what we have installed, not what we will install on a different building. Refrigerant compliance (R-454B for 2025+ AC installations) and rebate eligibility (Eversource heat pump program tiers) also affect equipment selection year by year.
- Are the dollar figures and savings numbers in the gallery accurate?
- The percentage reductions in gas, electric, or oil consumption are taken from utility-bill comparisons over equivalent heating degree day periods (Bradley International Airport NWS station data) or cooling-season equivalent days. The figures reflect the specific home and equipment shown; they should not be extrapolated to other buildings. A 31% gas reduction on a properly-sized steam boiler replacement in a 1923 Sedgwick Road home does not predict 31% savings in a 1957 Newington ranch with a forced-air system. We are happy to share the source utility-bill tracking with prospective customers under NDA.
- Do you take and post photos of customer homes without permission?
- No. All gallery photos are posted with written customer permission obtained before the project closes. Customer surnames are anonymized to first name and last initial; specific addresses are anonymized to nearest cross-street or neighborhood. Exterior shots avoid identifiable house numbers and license plates. If a customer requests removal of their project from the gallery at any time, the entry is removed within 48 hours.
