About Biozura Heating and Air
Joshua Scruggs started this company after one specific February call. A retiree on Sedgwick Road in West Hartford, a 1927 brick Colonial with original double-hung windows and a Burnham steam boiler from 1962, lost heat at 11 p.m. on a Sunday. Outdoor temperature: 3°F. The previous contractor had condemned her boiler over a “cracked section” he never opened the unit to confirm. Her quote for replacement: $13,800. Joshua got there at 12:40 a.m., pulled the wet base, found the actual failure — a stuck McDonnell & Miller 67 low-water cutoff seized with mineral buildup — and had her steam pressure back at 2 PSI by 3:15 a.m. for $84 in parts. The Burnham still runs. That gap — between what the diagnosis actually shows and what the customer gets quoted — is the reason this company exists.
The Founder — Joshua Scruggs
Joshua holds Connecticut Department of Consumer Protection unlimited HVAC contractor license #S1-0414829 and EPA Section 608 Universal certification #608U-2008-381467 for handling R-410A, R-454B, and legacy R-22 systems. He carries a B-2 limited boiler license #B2-0287345 for the cast iron steam and hot-water systems still running in roughly 40% of Hartford County’s pre-1960 housing stock. He has worked in residential and light-commercial HVAC across Greater Hartford since 2007, founding Biozura Heating and Air in 2014 after seven years at Hartford Mechanical Services, a Carrier and Bryant dealership on New Park Avenue.
His training stack: NATE-certified in Air Conditioning Service, Gas Heating Service, and Heat Pump Service. ACCA Manual J, S, and D coursework completed in 2011 through HVAC Excellence. RSES Class HE membership active since 2012. Continuing education hours logged annually through the Connecticut DCP for the 2022 Connecticut State Building Code and the 2024 IMC code-cycle requirements.
The discipline shows up in how every visit runs. Diagnosis before quoting. Measurements before opinions. A capacitor reading 32 microfarads on a 35 microfarad rated component is a different repair than one reading 8 microfarads — both produce identical symptoms of a condenser that won’t start. Most contractors quote the worst case. We quote what the meter shows.
Why Greater Hartford Breaks Generic HVAC
The Connecticut River valley isn’t Atlanta. It isn’t Chicago. It isn’t Boston. Equipment sized and tuned for any of those cities will underperform here for reasons that are physics and infrastructure, not opinion.
Climate Zone 5A Heating Loads
The 2021 IECC places Hartford County in Climate Zone 5A — cold, moist. Annual heating degree days at the Bradley International Airport station: approximately 6,180. The ASHRAE 99% winter design temperature for the Hartford valley floor is 4°F. The 1% summer design temperature is 88°F dry bulb, 73°F coincident wet bulb — meaning the cooling load includes serious latent (humidity) capacity, not just sensible BTU. That 84-degree spread, paired with summer dew points routinely above 65°F, means equipment selected for dry-climate Midwest catalogs will short-cycle through July and leave 60% relative humidity behind. We size to Hartford’s actual ASHRAE design conditions, not the manufacturer’s marketing climate.
Pre-1940 Housing Stock and Original Heating Systems
West Hartford’s Sunset Farm, West Hill, and Bishops Corner neighborhoods are largely pre-1940 construction. Hartford’s West End, Asylum Hill, and Frog Hollow likewise. These homes were built around coal-fired boilers later converted to oil or gas, with cast iron radiators, single-pipe or two-pipe steam, and original galvanized return air ductwork in the few homes that ever had forced air. Replacing a 1962 Burnham steam boiler with a modern modulating-condensing wall-hung unit isn’t a drop-in — the radiator EDR (equivalent direct radiation) has to match the new boiler’s net output to within 10%, or you get short-cycling and chronic comfort complaints. A previous contractor sizing based on square footage is how a 280,000 BTU steam system ends up replaced with an oversized 199,000 BTU modcon that delivers worse comfort than what it replaced. We measure EDR room by room before we quote.
Ice Dams and Connecticut Snow Loads
Hartford County design snow load is 30 PSF per the 2022 Connecticut State Building Code. Annual snowfall at Bradley averages 46 inches, with peak events exceeding 24 inches in a single storm (February 2013 dropped 23.4 inches in 30 hours). Ice dam formation along the eaves of West Hartford’s mid-century capes and the Bloomfield ranch tracts isn’t a roofing problem — it’s an HVAC and envelope problem. Warm attic air leaking from inadequate ductwork insulation and uninsulated mechanical penetrations melts the snowpack mid-roof; refreezing at the cold eave creates the dam. Our attic mechanical work includes R-49 minimum cavity insulation per the 2022 Connecticut State Building Code, sealed duct boots with mastic (not foil tape), and verified attic-to-conditioned-space air sealing using a blower door test post-install.
Humid Continental Summer Cooling
Hartford summers hit 90°F+ for an average of 11 days per year, with dew points climbing into the upper 60s for weeks at a stretch. A right-sized AC system needs to run long enough to remove latent load — not just hit the thermostat setpoint and shut off. An oversized 4-ton condenser on a 2,400 square foot Colonial that only needs 2.5 tons will cool the house in 12 minutes, never drop the indoor humidity below 60%, and leave the homeowner running a portable dehumidifier in August. Variable-speed condenser pairs (Carrier Greenspeed, Trane XV20i, Lennox Signature Collection) handle the latent removal at part-load conditions where two-stage and single-stage systems fail. We spec to Manual J latent capacity, not just sensible tonnage.
What We Do
Residential and light-commercial HVAC for properties across Hartford County, with technical depth in the categories where Connecticut River valley conditions and pre-war housing stock create non-standard demands:
- Furnace installation and repair — Carrier, Trane, Lennox, Rheem, Bryant, and Goodman 80% and 95%+ AFUE single-stage, two-stage, and modulating systems. Vent termination per CT 2022 amendments to the IMC, sidewall PVC clearance verification, and Connecticut Natural Gas or Eversource gas pressure confirmation (7″ WC nominal delivery).
- Air conditioning installation and repair — R-454B compliant condenser selection for the 2025 refrigerant transition, line set sizing, condenser placement analysis for south-facing walls in Sunset Farm and West Hill where measured ambient runs 6–10°F hotter than the Bradley NWS station.
- Heat pump systems — cold-climate variable-capacity units rated for 100% capacity at 5°F outdoor temperature. Mitsubishi Hyper-Heat, Daikin Aurora, Bosch IDS Premium. We size to Hartford’s 4°F ASHRAE 99% design temp, not the manufacturer’s optimistic AHRI 47°F rating. Eversource heat pump rebates ($1,500–$15,000 depending on equipment) processed in-house.
- Boiler installation and repair — steam (cast iron sectional, one-pipe and two-pipe), hot water (cast iron monobloc, modulating-condensing wall-hung), and hydronic radiant. Common across the Avenues, West Hartford Center, and historic Wethersfield, where original systems often pre-date 1955. Buderus, Viessmann, Weil-McLain, Burnham, Crown, and Peerless brands. EDR-based sizing on every steam project.
- Indoor air quality — MERV 13 minimum filtration, whole-home HEPA bypass, UV-C coil treatment, steam and bypass humidification, and HRV/ERV ventilation for tight envelopes in newer Avon and Farmington subdivisions where infiltration rates run below 3 ACH50.
- Commercial rooftop units and service contracts — office condos along Farmington Avenue, retail along Park Road, light industrial in Newington, and small medical/dental along North Main Street and Albany Avenue. Carrier 48HC and 50HC series, Trane Voyager, Lennox Strategos.

How We Work
Diagnose. Don’t Guess.
Every repair visit starts with measurement. Superheat and subcooling on cooling systems. Draft, manifold pressure, and combustion analysis on furnaces (target: under 100 ppm CO air-free, stack temperature within manufacturer spec). On steam boilers, low-water cutoff function test, gauge glass condition, skim port inspection, and operating pressure verification (target: 0.5–2 PSI for residential one-pipe steam — not the 10 PSI most contractors leave dialed in). Static pressure across the air handler — total external static under 0.5″ WC for residential blowers, under 0.8″ WC for ECM variable-speed. Amperage on motors compared to nameplate FLA. The data tells us the failure. Then we quote.
Right-Sized. Not Rule-of-Thumb.
New system quotes start with an ACCA Manual J load calculation. Then Manual S equipment selection. Then Manual D duct verification if the existing duct system is staying. A 1927 West Hartford brick Colonial with original double-hung windows can carry an 85,000 BTU/hr design load on 2,200 square feet. A 2019 Farmington new-build with R-49 attic insulation and triple-pane fiberglass windows might carry 32,000 BTU/hr on the same square footage. Tonnage by rule of thumb gets one of those two wrong — usually both.
Priced in Daylight.
Every estimate breaks out equipment cost, labor hours, permit fees, refrigerant by pound, electrical or venting modifications, and warranty registration. No “package pricing” that hides margin. No verbal estimates. No same-day pressure. We pull permits through West Hartford Building & Inspections, Hartford Department of Development Services, Bloomfield, Newington, or whichever municipal authority has jurisdiction — not as a courtesy, but because unpermitted HVAC voids most homeowners’ insurance policies and creates disclosure problems at sale through The Hartford, Travelers, or Liberty Mutual underwriting reviews.
What Customers Actually Say
The pattern across 218 Google reviews and 41 Nextdoor mentions is consistent. Technicians arrive inside the quoted window. Diagnosis gets explained with photos or thermal imaging, not jargon. Written quotes precede work, never follow it. And the company doesn’t run replacement-sales theater. A 13-year-old Trane XV80 passing combustion analysis, with no heat exchanger cracks visible under borescope, gets a clean inspection report and a maintenance recommendation — not an $11,000 system pitch.
A Sunset Farm homeowner, Patricia M., hired us for a second opinion after a competitor quoted $15,400 for full furnace replacement on her 1998 Carrier Infinity 96. The actual failure was a $290 inducer motor and a $52 hot surface igniter. The Carrier ran another seven winters. A small business owner on Farmington Avenue, Robert K., had us replace a 16-year-old Trane rooftop unit on his 3,200 square foot insurance brokerage — we installed a Carrier 48HC with economizer for outdoor air ventilation, sized to ASHRAE 62.1 for the occupancy load. His July utility bill dropped 27% the following summer. A Bloomfield homeowner, Marcus T., called us after two competitors told him he needed a complete duct replacement — we ran static pressure tests, found a single collapsed flex run in the attic, and fixed it for $230.
Frequently Asked Questions
- Who owns Biozura Heating and Air?
- Joshua Scruggs founded and owns Biozura Heating and Air. The company has operated from its 10 N Main Street office in West Hartford Center since 2014, serving residential and light-commercial customers across Hartford County under Connecticut DCP unlimited HVAC contractor license #S1-0414829 and B-2 limited boiler license #B2-0287345.
- Why does HVAC equipment perform differently in the Hartford region?
- Three measurable factors. First, Climate Zone 5A puts Hartford in cold-moist conditions with approximately 6,180 heating degree days annually and an ASHRAE 99% winter design temperature of 4°F — cold enough that standard-rated heat pumps lose capacity exactly when load peaks. Second, summer dew points routinely exceed 65°F, meaning AC equipment must be sized for latent (humidity) removal, not just sensible BTU; oversized condensers leave homes at 60%+ relative humidity. Third, roughly 40% of Hartford County’s housing stock predates 1960 and was originally heated by coal-converted steam or hot water boilers with cast iron radiators — EDR-based sizing, not square footage, controls replacement system selection. Generic equipment quotes ignore all three.
- What cities does Biozura Heating and Air serve?
- West Hartford, Hartford, Bloomfield, Newington, Avon, Farmington, New Britain, Wethersfield, East Hartford, Windsor, and Simsbury.
