Which heating system is right for your home?
The short answer: a furnace burns fuel to create heat and is a proven, budget-friendly choice, while a heat pump moves heat using electricity, runs more efficiently, and cools your home in summer too. The best fit depends on your home, your budget, and whether you want heating and cooling in one system.

How much does a new furnace cost in Durham?
Most new furnace installations in Durham fall between roughly $4,500 and $8,500, depending on the size of your home, the efficiency rating you choose, and any ductwork changes. We give you an exact, upfront quote after a free in-home assessment — no guessing.
How long does a furnace installation take?
Most furnace replacements are completed in a single day. A more involved job — adding a heat pump, reworking ductwork, or a full system change — can take one to two days. We’ll give you a clear timeline before we start.
Furnace or heat pump — which is right for my home?
A furnace is a proven, lower-upfront-cost choice, while a heat pump is more efficient and heats and cools your home in one system. The best fit depends on your home, your budget, and whether you want cooling too — we’ll walk you through it during your free estimate.
What are the signs I need a new furnace?
Common signs include rising energy bills, uneven heating, frequent repairs, unusual noises, and a furnace that’s more than 15 years old. If a few of these sound familiar, a free assessment will tell you whether a repair or a replacement makes more sense.
How often should I have my furnace serviced?
Once a year, ideally before the heating season. An annual tune-up keeps your furnace safe and efficient, helps protect your warranty, and catches small problems before they leave you without heat on a cold night.
Do you offer financing on new heating systems?
Yes — flexible monthly payment options are available on qualifying installations, subject to approval. We’ll walk you through the real terms during your estimate so you can choose what fits your budget.
