HVAC Tips

Protecting Historic Homes in Greenwich and New Canaan From Furnace Strain

Greenwich and New Canaan are home to many historic properties, from early 20th-century colonials to classic farmhouses. While these homes are full of character, they can also pose unique challenges for modern HVAC systems.

Older construction often includes:

  • Original ductwork or narrow vents that limit airflow
  • Less insulation and drafty windows that cause uneven heating
  • Aging electrical systems that can affect furnace operation

During February’s cold snaps, these factors make furnaces work harder, increasing the risk of breakdowns and high energy bills.

Common Furnace Issues in Historic Homes

1. Uneven Heating

Historic homes may have multiple levels, thick walls, or unique layouts that make heat distribution tricky. Rooms far from the furnace may remain colder, causing the system to run longer and work harder.

2. Drafts and Poor Insulation

Older windows, doors, and unsealed walls allow cold air to infiltrate. Furnaces must compensate for these leaks, increasing wear and energy consumption.

3. Aging Furnace Components

Historic homes often have furnaces that are several decades old. Burners, heat exchangers, and blowers may not perform efficiently, especially under the strain of prolonged winter use.

Tips to Protect Your Furnace This February

1. Schedule a Professional Inspection

A certified HVAC technician can evaluate your furnace’s performance, check for worn parts, and ensure airflow is optimized for your home’s unique layout. Early maintenance reduces the risk of emergency breakdowns during cold spells.

2. Upgrade Thermostats and Zoning

Smart or programmable thermostats, combined with zoning systems, allow you to control temperatures in individual rooms. This reduces strain on the furnace while maintaining comfort throughout the home.

3. Seal Drafts and Insulate Strategically

Weatherstripping, caulking, and adding insulation in attics or basements helps maintain consistent indoor temperatures and reduces furnace workload. Even small improvements in draft-prone areas can have a big impact.

4. Maintain Proper Airflow

Ensure vents and registers are unobstructed and clean. Older ductwork may need sealing or balancing to ensure heat is distributed evenly and efficiently.

5. Replace Filters Regularly

Dust and debris accumulate faster in older homes due to older ductwork or less airtight construction. High-quality filters replaced monthly keep air clean and reduce strain on your system.

Local Insight
