Complete Furnace Installation for Connecticut Homes & Commercial Properties
Furnace installation from Ralph Mann & Sons is a complete, managed service from the first site visit through final system startup.
Connecticut state-licensed technicians handle the engineering, the equipment, the permits, and the inspections.
No subcontractors. No shortcuts.
Furnace installation covers new construction heating systems, full furnace replacements for aging equipment, and heating capacity additions for home additions. It is a distinct service from furnace repair, which addresses component failures in systems that still have remaining useful life, and from boiler replacement, which serves homes with hot-water or steam heating systems.
Every furnace installation includes:
Ductwork is tested for static pressure and airflow capacity during every installation. Most existing duct systems accommodate new equipment with minor modifications improvements are recommended only when necessary. If a full ductwork replacement or a gas line upgrade is required, Ralph Mann & Sons technicians handle that work directly.
Gas, Propane, and Oil Furnaces
Ralph Mann & Sons Installs All Three
Ralph Mann & Sons installs furnaces for the three major fuel types available to Connecticut homeowners. The right choice depends on your home's existing infrastructure, your town's utility access, and your long-term energy goals.
Natural gas furnaces
The most common choice in towns with municipal gas service, combining reliable performance with competitive fuel costs
Propane furnaces
A strong option for rural Connecticut homes and communities where natural gas lines are unavailable
Heating oil furnaces
A proven, high-BTU solution for homes already equipped for oil delivery, with modern oil furnaces reaching efficiency ratings well above older systems
Ralph Mann & Sons also specializes in fuel conversions moving homes from oil to natural gas or from fossil fuels to heat pump systems.

A no-obligation consultation gives you a direct answer.
Standard Efficiency vs. High-Efficiency Condensing Furnaces
Choosing between a standard efficiency and a high-efficiency condensing furnace is one of the most common decisions Connecticut homeowners face before a replacement. Ralph Mann & Sons installs both and provides transparent guidance on the trade-offs, no upsell pressure, just the information you need.
| Feature | Standard Efficiency | High-Efficiency |
|---|---|---|
| AFUE Rating | 80% | 90-98%+ |
| Venting | Traditional chimney or flue | Sidewall PVC - no chimney required |
| Upfront Cost | Lower | Higher |
| Annual Fuel Savings | Baseline | 15-30% vs. standard efficiency |
| Rebate Eligibility | Limited | Qualifies for Energize CT and utility rebates |
| Best For | Budget-focused replacement; homes without PVC venting access | Long-term fuel savings; new construction; high-usage homes |
High-efficiency condensing systems extract heat from combustion gases that standard systems exhaust as waste. They feature modulating gas valves that adjust fuel input to match heating demand in real time, sealed combustion that draws outside air directly to the burner, and multi-stage controls for consistent comfort. Standard efficiency systems offer a lower upfront investment with proven, dependable performance.
Ralph Mann & Sons helps customers apply for Energize CT rebates and applicable utility incentives on qualifying high-efficiency installations.

Clear Signs Your Furnace Is Ready for Replacement
Most Connecticut homeowners schedule furnace replacement in the fall before heating season to lock in appointment availability and start winter with a system they can rely on. That said, Ralph Mann & Sons installs furnaces year-round, including 24/7 emergency replacements when a system fails mid-winter.
Ralph Mann & Sons technicians give honest assessments at every visit. If repair is the better path, they say so directly.

How a Furnace Installation With
Ralph Mann & Sons Works
Three steps. One team. Fully managed from your first call to final startup.
1
Home Assessment and System Design
A licensed technician visits your home, evaluates structure, insulation, existing ductwork, and heating load, then applies Manual J heat-loss calculations and proprietary design software to specify the right equipment. Not oversized, not undersized.
2
INSTALLATION & PERMIT COORDINATION
Ralph Mann & Sons handles all permit applications and municipal inspection coordination for mechanical, gas, and electrical work across every Connecticut town we serve. Installation is performed exclusively by direct-employee technicians holding the appropriate Connecticut state licenses.
3
Commissioning, Safety Verification, and Customer Walkthrough
Every installation closes with full system commissioning: startup testing, combustion analysis, carbon monoxide measurement, and safety control verification. Before the team leaves, they walk you through system operation, maintenance requirements, and warranty details.
Cost of Furnace Installation in Connecticut
Furnace installation costs in Connecticut typically range from $4,500 to $8,500 depending on equipment type, efficiency tier, home size, and the scope of work involved. The table below shows general ranges based on fuel type.
| Furnace Type | Typical Installed Cost Range (CT) |
|---|---|
| Natural Gas - Standard Efficiency | $4,500 - $6,500 |
| Natural Gas - High Efficiency (90%+ AFUE) | $6,000 - $8,500+ |

These ranges reflect equipment and labor. Final cost depends on your home's square footage, existing ductwork condition, venting requirements, thermostat upgrades, and permit fees.

Ralph Mann & Sons provides detailed, transparent proposals before any work begins. There are no hidden fees and no surprises on the final invoice.
Annual Maintenance Keeps Your New Furnace Running at Peak Performance
A new furnace is one of the most significant investments a Connecticut homeowner makes. Annual professional maintenance protects that investment, extends equipment life, and is often required to maintain manufacturer warranty coverage.
Ralph Mann & Sons maintenance plans include:
Maintenance plan members receive priority scheduling, discounted repair rates, and extended warranty coverage. Service is typically scheduled in the fall to prepare your system before heating season begins.
