Gas Furnace Installation in Simsbury, Connecticut
Simsbury furnace installations divide into specific patterns that reflect the town’s housing inventory and the gas service availability map: oil-to-gas conversions in West Simsbury, Tariffville, and parts of Pleasant Valley where Yankee Gas (now Eversource) has extended service over recent decades but legacy oil systems remain; like-for-like gas furnace replacements in the newer subdivisions and West Simsbury tract housing as 1990s-2000s equipment ages past 15-20 years; efficiency upgrades from 80% AFUE to 95% AFUE condensing technology; and the special case of Simsbury Center historic homes plus Pleasant Valley estate homes where conventional gas furnace conversion is rarely the right answer (steam or hot-water boiler systems served these homes originally; ductless mini-split with cold-climate heat pump is often a better alternative than ductwork installation). Connecticut DCP Unlimited HVAC License #S1-0414829; Tomás Reyes leads complex installations including oil-to-gas conversions and cold-climate heat pump alternatives.
Simsbury Furnace Installation Project Categories
Oil-to-Gas Conversion
Common in West Simsbury and Tariffville where Yankee Gas (now Eversource) has expanded service over the last 20 years. Scope:
- Existing oil furnace removal: Decommission and remove existing equipment.
- Oil tank decommissioning: Connecticut DEEP coordination for underground tanks; less complex for above-ground basement tanks. Licensed oil-handling contractor handles residual fuel removal.
- Gas service coordination: Eversource gas service customer service 800-286-2828 (for areas previously served by Yankee Gas) or CNG 860-947-2273 depending on which serves specific street. Some Simsbury streets are at the edge of gas service area and require utility service extension.
- Gas piping installation: Run gas piping from meter to new furnace, install sediment trap, pressure-test per Connecticut 2022 Fuel Gas Code.
- New gas furnace installation: Equipment, venting (B-vent for 80% AFUE, PVC for 95%), condensate drainage, electrical, controls.
- Permit and inspection: Simsbury building permit; pressure-test witness on gas piping.
Timeline: 2-4 days. Pricing: $7,400–$14,200 total.
Like-for-Like Replacement
Most common in West Simsbury and newer subdivisions with existing gas service. Timeline: 1 day. Pricing: $4,400–$8,400.
Efficiency Upgrade (80% to 95% AFUE)
Same considerations as other Hartford County service areas: venting category change (PVC instead of metal B-vent), condensate drainage requirement, chimney implications for water heater, $800-$1,600 equipment cost premium, $250-$650 Eversource rebate.
Timeline: 1-2 days. Pricing: $5,800–$11,400.
Historic Simsbury Center — Why Furnace Conversion Often Isn’t the Answer
Pre-1900 Simsbury Center homes (and many Pleasant Valley estate homes) have steam or hot-water boiler heating, not forced-air. Converting to gas furnace requires whole-home ductwork installation, which:
- Costs $8,400-$22,400 additional for ductwork.
- Often damages historic interior finishes (plaster walls, original woodwork, paneled rooms) that contribute to the home’s character and value.
- May require Simsbury Historic District Commission approval for visible interior changes on contributing structures.
- Sometimes infeasible without alterations the homeowner will not accept.
Better alternatives for most historic Simsbury homes:
- Replace existing boiler with modern high-efficiency boiler: Preserves heating system type; no ductwork required; available in 90-95% AFUE condensing models (Burnham Alpine, Lochinvar Knight, Weil-McLain Ultra Series, Triangle Tube Prestige).
- Cold-climate heat pump with ductless distribution: Modern cold-climate heat pumps operate effectively to −5°F or lower; multi-zone ductless system distributes heat (and cooling) without ductwork. Mitsubishi Hyper-Heat, Daikin Aurora, Carrier Greenspeed equipment. Eversource heat pump incentives $750-$3,500. Sometimes installed as primary heating with existing boiler retained for backup during extreme cold; sometimes installed as primary heating replacing boiler entirely.
- Hybrid system: Existing boiler for primary heat plus ductless mini-split for cooling and shoulder-season heating. Heat pump operation supplements boiler during mild conditions; boiler provides heat during deep cold. Lower capital cost than full system replacement; some efficiency benefit from heat pump operation when conditions favor it.
The pre-installation consultation explores these alternatives before committing to gas furnace conversion. For some historic homes, gas furnace is the right answer (renovation has already affected historic finishes; customer values forced-air distribution for cooling integration); for many, the alternatives serve better.

Manual J Load Calculation for Simsbury Homes
Standard Connecticut winter design conditions; Talcott Mountain microclimate may produce slightly more severe extremes than Bradley Airport reference. Typical Simsbury home heat loss:

Frequently Asked Questions
- I have an oil furnace in my Simsbury home. Should I convert to gas?
- Depends on gas service availability, current oil equipment age, and cost-comparison. Gas advantages: lower operating cost (typically 30-50% cheaper than oil per BTU); cleaner combustion; modern equipment availability. Oil advantages: existing infrastructure if equipment is relatively new; no service availability concerns. Specifically for Simsbury: Yankee Gas/Eversource has expanded service in West Simsbury and Tariffville over the last 20 years, but some streets are at the edge of service area requiring utility service extension (which adds cost). Conversion break-even point typically 5-8 years for homes with high heating bills. Cold-climate heat pump is also worth considering as an alternative to gas conversion — Eversource rebates and IRA tax credits substantially reduce the upfront cost.
- My home in Simsbury Center has a steam boiler. Should I convert to a gas furnace?
- Rarely the right answer for true historic Simsbury Center homes. Converting requires whole-home ductwork installation ($8,400-$22,400 additional), which typically damages historic interior finishes and may require Historic District Commission approval. Better alternatives: (a) Replace existing boiler with modern high-efficiency condensing boiler (90-95% AFUE) — preserves heating type, no ductwork, $6,400-$12,400. (b) Cold-climate heat pump with ductless distribution — modern cold-climate equipment operates to -5°F+, multi-zone ductless distributes heat and cooling, Eversource rebates $750-$3,500. (c) Hybrid system — existing boiler for deep-cold backup plus ductless heat pump for shoulder seasons. The consultation explores which fits your specific home.
- Should I consider a cold-climate heat pump instead of a gas furnace?
- Worth considering, especially for: (1) Oil-to-gas conversion candidates — heat pump avoids the gas service coordination, gas piping installation, and oil tank decommissioning complexity. (2) Homes considering AC installation alongside heating upgrade — one equipment investment handles both. (3) Customers prioritizing environmental impact — heat pumps run on electricity which can come from renewable sources. (4) Homes in milder microclimates within Simsbury — Tariffville’s Farmington River corridor and lower elevations stay slightly warmer than Talcott Mountain side. Eversource rebates ($750-$3,500) and federal tax credits substantially reduce the cost premium versus gas furnace. We provide cost-comparison analysis as part of the consultation.
- How long does furnace installation take?
- Like-for-like replacement: typically 1 day on-site. Efficiency upgrade (80% to 95% AFUE with venting changes): 1-2 days. Oil-to-gas conversion: 2-4 days including tank decommissioning, gas piping, new furnace install, and utility coordination. Boiler replacement (preserving hydronic distribution): 1-2 days. Cold-climate heat pump installation: 2-3 days for whole-home multi-zone system; 1-2 days for single-zone supplemental heat pump. Major ductwork modifications add 1-2 days. Whole-home ductwork installation (historic conversion): 5-10 days.
- Do I need a permit to replace my furnace in Simsbury?
- Yes. Simsbury building code requires a mechanical permit for any furnace installation or replacement. The permit ensures proper installation, pressure-test documentation on gas piping work, inspection of venting and combustion air provisions, and verification of safety device function. Biozura handles the permit application. Unpermitted work creates liability if there’s a gas leak, CO incident, or fire later. Permit fees run $150-$320; included in project quote. Historic District Commission review additionally applies to contributing structures in Simsbury Center for visible exterior changes.
