Furnace Installation & Replacement
New heating systems sized correctly for your home. Trane dealer with 10-year warranty.
Is It Time for a New Furnace? Here's How to Know.
If your furnace is struggling to keep your home warm, making strange noises, or costing more to run every winter, it may be time for an upgrade. In Hanover PA and Westminster MD, homeowners count on Siegman & Schaefer to help them make the right call — repair or replace — without pressure or upselling.
We install the full line of Trane furnaces, known for their reliability, efficiency, and long equipment life. Every installation starts with a proper in-home load calculation to make sure you get the right size system — not too big, not too small. An improperly sized furnace wastes energy, wears out faster, and never keeps your home truly comfortable.
Our installation team takes pride in clean workmanship and attention to detail. When we're done, we walk you through your new system, answer every question, and make sure you're completely comfortable before we leave.

- Frequent repairs — especially if repair costs exceed 50% of a new system
- Uneven heating — some rooms are warm, others are cold
- Rising energy bills despite regular maintenance
- Your system uses R-22 refrigerant (being phased out)
- Excessive noise — banging, rattling, or squealing
- Yellow or flickering pilot light (potential carbon monoxide risk)
- Visible rust, cracks, or corrosion on the unit

Frequently Asked Questions About Furnace Installation
If your furnace is over 15 years old, needs repairs costing more than 50% of a new system, uses R-22 refrigerant, or your energy bills keep rising despite maintenance, replacement is usually the smarter investment. We'll give you an honest recommendation.
Furnace sizing depends on your home's square footage, insulation, window configuration, ductwork, and climate zone. We perform an in-home load calculation to determine the exact right size — oversized and undersized systems both cause problems.
AFUE (Annual Fuel Utilization Efficiency) measures how efficiently a furnace converts fuel to heat. We recommend 95%+ AFUE for most homes in our area. Higher efficiency means lower utility bills and better comfort.
Most residential furnace installations are completed in one day. If ductwork modifications are needed, it may take two days. We'll give you a clear timeline before work begins.
