Energy costs in Maryland have gone up steadily over the past several years, and older homes feel it the most. Drafty windows, poor insulation, and aging HVAC systems all contribute to monthly bills that are higher than they need to be. The good news is that the upgrades with the biggest impact on energy savings also happen to be the ones that improve how the house feels day to day. At Remodeling Wizards of Maryland, we have always encouraged homeowners to think about efficiency as part of any remodeling project, not as a separate expense. Our approach has included green technology options since the beginning.
Windows: the single biggest energy leak in most homes
We covered this in depth in our guide to window replacement, but it bears repeating: the Department of Energy estimates that 25 to 30 percent of residential heating and cooling energy is lost through windows. If you are living with single-pane windows, or double-pane units with failed seals, upgrading to ENERGY STAR-certified windows is one of the most impactful changes you can make. The comfort difference is noticeable immediately, and the energy savings build over time.
Insulation: invisible and undervalued
Many older Maryland homes are under-insulated by current standards. The attic is usually the biggest culprit. Heat rises, and in winter, it escapes through an under-insulated attic at a rate that directly inflates your heating bill. Adding blown-in insulation to the attic is relatively affordable and can reduce heating costs meaningfully.
Basement rim joists are another common problem area. The rim joist sits where the foundation meets the framing, and in many older homes, it has little or no insulation. Spray foam in this area seals air gaps and adds thermal resistance in a spot that is otherwise a significant source of heat loss.
Siding: more than just curb appeal
When homeowners think about siding replacement, the conversation usually starts with appearance. But new siding also creates an opportunity to add or improve the insulation layer behind it. Insulated vinyl siding, fiber cement with a foam backing, and other modern options provide a continuous insulation barrier that reduces thermal bridging through the wall studs. The result is a house that holds temperature more consistently and costs less to heat and cool.
Doors: the overlooked energy drain
An old, poorly sealed exterior door can leak as much air as a small open window. Door replacement with an insulated fiberglass or steel entry door improves the seal significantly. Fiberglass doors in particular offer excellent thermal performance and do not warp the way wood doors can over time. Weather stripping around the frame and a proper threshold seal complete the picture.
HVAC tune-ups and upgrades
An aging furnace or air conditioner loses efficiency gradually, so the decline is easy to miss. If your system is 15 or more years old, it is almost certainly less efficient than a modern unit. Even if a full replacement is not in the budget, a professional tune-up, duct sealing, and a programmable thermostat can reduce energy use without a major investment.
If you are planning a remodel that opens up walls, that is the ideal time to address ductwork. Leaky ducts in unconditioned spaces like attics and crawlspaces can waste 20 to 30 percent of the air your system produces.
Water heating: the hidden energy hog
Water heating accounts for roughly 18 percent of a home’s energy use, according to the Department of Energy. If you are remodeling a bathroom or kitchen and the water heater is older than 10 years, it is worth evaluating whether a more efficient unit makes sense. Heat pump water heaters use significantly less energy than traditional electric tank heaters and are a particularly good fit for Maryland’s climate.
Tax credits and incentives
The federal Inflation Reduction Act provides tax credits for many energy-efficient home improvements, including windows, doors, insulation, and heat pumps. Maryland’s EmPOWER programs, administered through local utilities like BGE and Pepco, offer additional rebates. Between federal and state incentives, homeowners can recover a meaningful portion of the cost. The ENERGY STAR rebate finder is a good place to start checking what is available in your area.
Let efficiency be part of the plan
Any time you are remodeling, you have an opportunity to improve efficiency at a fraction of what it would cost as a standalone project. We build that thinking into every consultation. Reach out to schedule yours and we will walk through the options that make sense for your home and your budget.
Frequently asked questions
What is the most cost-effective energy upgrade for an older home?
Attic insulation and air sealing typically offer the best return relative to cost. They are among the least expensive upgrades and have an immediate effect on heating and cooling bills.
Are energy-efficient windows worth the cost?
Yes, especially in homes with original single-pane windows. ENERGY STAR-certified windows reduce energy costs by an average of 12 percent and improve comfort throughout the house. Combined with federal tax credits, the effective cost is lower than many homeowners realize.
What energy tax credits are available in Maryland?
The federal Inflation Reduction Act provides credits up to $3,200 per year for qualifying improvements including windows, doors, insulation, and heat pumps. Maryland utility companies also offer rebates through EmPOWER programs. Your contractor or a tax professional can help you identify what applies to your project.
