Why we size the system by calculation
Many companies replace a unit with the same size it had before. That shortcut ignores changes in the house. New windows, added insulation, a finished basement, or altered ductwork all change how much heating and cooling a home needs.
We run a load calculation using the industry-standard Manual J method. It gives a number based on your home, not on the old unit. An oversized system short-cycles, leaves the air damp, and wears out early. An undersized one struggles on the hottest and coldest days.
Good, better, best, in writing
On most replacements we show three options, so you can compare them side by side. Each one lists the equipment, the efficiency rating, the installation work, the warranty terms, and the total.
- Good: reliable equipment that meets the code and fits a tight budget
- Better: higher efficiency and quieter operation, with a longer warranty
- Best: the highest efficiency and the most comfort features we install
We explain the efficiency ratings clearly. SEER2 measures cooling efficiency, and AFUE measures how much of a furnace's fuel becomes heat. A higher number means lower running costs, but it only matters if your home and budget make the extra cost worthwhile.
Before you sign
Take the written quote home. Compare it with others. Ask us to explain any line you do not understand. We would rather you decide with clear information than decide quickly.
Financing
Financing is available for larger replacements. Approval depends on your credit and the lender's terms. We show you the monthly payment, the interest, and the total cost before you choose, so there are no surprises later.
Common questions
Why do you do a load calculation instead of matching my old system size?
Homes change over time. Windows, insulation, and ductwork all affect how much heating and cooling a home needs. A Manual J load calculation sizes the system to your home. Matching the old size often installs a system that is too large or too small.
Are there rebates or tax credits for high-efficiency systems?
Some high-efficiency equipment may qualify for federal or utility rebates. Eligibility changes, so we check current programs for your equipment and location before you decide.
How long does a replacement take?
Most residential installations are finished within a day or two, depending on the equipment and any ductwork needed. We give you the schedule in writing before the work begins.
