Key takeaways
In the Maryland market, a full HVAC replacement commonly falls within a broad range of about $6,000 to $15,000 or more. A simple swap of a single component such as a furnace or condenser sits at the lower end, while a complete heating and cooling system with high efficiency and new ductwork reaches the higher end. These figures are general ranges only, not quotes; the accurate number for your home comes from an in-home assessment.
The biggest cost drivers are system type (furnace, air conditioner, heat pump, or a full split system), the size or tonnage needed for your square footage, and the efficiency ratings such as SEER2 for cooling and AFUE for heating. Labor, local permit fees in Montgomery County, and the complexity of the installation also factor in. Each home is different, so two houses on the same street can have very different totals.
Ductwork that is leaky, undersized, or poorly sealed can add to the project, since a new high-efficiency system only performs as well as the ducts that carry the air. If your ducts need repair, sealing, or replacement, that work raises the overall cost but protects your comfort and energy savings. During an estimate, our technicians inspect the ductwork so nothing is overlooked.
Yes. Systems with higher SEER2 and AFUE ratings cost more upfront but use less energy, which lowers your monthly bills through Maryland’s humid summers and cold winters. The right balance depends on your budget, how long you plan to stay in the home, and your comfort goals. A good contractor helps you weigh upfront cost against long-term savings rather than pushing the most expensive option.
Online ranges are useful for planning, but they cannot account for your home’s size, layout, existing equipment, ductwork, and electrical setup. An in-home assessment lets a technician measure your space and recommend a properly sized system, which avoids overpaying or installing a unit that is too small.

Yes, many homeowners qualify for utility rebates, manufacturer promotions, or tax incentives on high-efficiency equipment. Financing can also spread the cost into manageable monthly payments. Ask Shemtov Systems which current options apply to your project when you schedule your estimate.
A straightforward replacement is often completed in one day, while more involved projects with ductwork or multiple systems can take two or more days. Your technician will give you a realistic timeline during the in-home estimate. Factors like home layout and permit handling can affect scheduling.
Both work well in Maryland, and the right choice depends on your home, fuel access, and comfort preferences. Heat pumps are efficient in our climate and handle both heating and cooling, while gas furnaces deliver strong heat during cold winters. A technician can compare options and costs for your specific situation.
No reputable contractor can guarantee an exact HVAC replacement price by phone, because the cost depends on your home’s size, ductwork, and existing equipment. The accurate number comes only from an in-home assessment. Call Shemtov Systems at 240-355-3333 to schedule a free estimate.
