Precision HVAC Sizing Starts With LiDAR Technology
Getting heater sizing right isn’t about guesswork or square-footage shortcuts, but about measuring how your home actually lives and breathes. Proper sizing starts with a load calculation, like the industry-standard Manual J, and LiDAR scanning gives our team detailed data to work from, including your home’s layout, ceiling heights, insulation patterns, and airflow pathways.
That information allows us to size your furnace to match real conditions, not estimates, so it delivers steady warmth without overworking itself. An oversized unit short-cycles, wears out early, and can struggle with humidity control, while an undersized one runs nonstop trying to keep up. The right size means a system that runs smoother, lasts longer, and keeps every room comfortable instead of overheating some spaces while others stay chilly.
Don’t let lack of heat hold you back.

Burning Questions About Heater Replacement
Furnace installation in the Lakeway area commonly runs about $3,000 to $7,500, depending on the type of system, its efficiency rating, and what your home needs. High-efficiency furnaces cost more upfront but save on heating bills over time, and older homes may need ductwork inspection, cleaning, sealing, or resizing that adds to the project.
We give you upfront pricing and a free estimate before any work begins, so you can compare options that fit your budget. Flexible financing is also available to make a new system easier to purchase.
Proper sizing matters more than most homeowners realize: too small strains, too large wastes energy and leads to short-cycling and premature wear. That’s why we evaluate your home carefully before making recommendations.
We consider things like:
- Square footage and layout
- Insulation quality and ceiling height
- Window placement and heat loss
- ‘Existing ductwork and airflow
When your furnace is sized correctly, it runs smoother, lasts longer, and keeps every room comfortable. That’s the kind of install that pays off season after season.
Most Lakeway homes use either a gas furnace or a high-efficiency electric heat pump. Because the local climate brings long, hot summers and short, mild winters, a heat pump that handles both heating and cooling is often a strong fit, while a gas furnace delivers quick, powerful heat on the coldest nights. A dual-fuel system combines a heat pump with a gas furnace and switches between them for the best efficiency.
We evaluate your entire heating and cooling system, not just the furnace, including how new equipment pairs with your air conditioning, so everything works together.
Most furnace installations take about four to eight hours, depending on system type and existing setup. Before installation, we review the plan, timeline, and expectations so there are no surprises. Our team handles removal of old equipment, installation, testing, and cleanup as part of the job.
Lakeway requires permits for mechanical work, with applications handled through the city’s online Civic Self Service portal, and installations must meet local building codes, including the 2021 International Mechanical Code. Once the work is complete, we walk you through the operating instructions and answer any questions, so you have peace of mind knowing your heat is ready to go.
Routine maintenance is the best way to protect your investment. Annual tune-ups keep heating systems running efficiently, catch small issues early, and help prevent the costly repairs and breakdowns that come with neglect.
Our maintenance plans include two maintenance visits per year, priority emergency response, repair discounts, and a 5% purchase accrual toward a future system replacement.
