We Make It Easy To Keep Everything Running Smoothly

Contact us online or call us at 770.594.9969 to schedule an appointment. We'll call you to confirm your time and send you a confirmation email with a picture of your tech, so you know who to watch for.



We are upfront and transparent with your options.

We'll come to your home (for free) and do a load calculation, a complex measurement of how much heating your home requires. This makes sure you get a furnace that will fit your home and your needs. Then, we'll give you multiple options with straightforward pricing for each.

On the day of the install, your installation team will:

  1. Lay down drop cloths and wear shoe covers to protect your home.

  2. Install your new furnace (typically this takes half a day).

  3. Leave your home cleaner than it was when we arrived.

Signs You Need A New Furnace

You might want to consider investing in a new unit if your current one:

  • Is more than 15 years old. Most furnaces last roughly 15-20 years. If yours is nearing the end of its lifespan, it's time to start thinking about a new unit.

  • Doesn't keep you comfortable. This could be a sign that your furnace is the wrong size or approaching the end of its life. In both cases, you're usually better off investing in a new unit.

  • Needs repairs frequently. This is often a sign that your furnace is on its way out. It's usually more cost-effective in the long run to invest in a new unit, rather than waste money on costly repairs.

  • Causes higher heating bills. This is usually a sign that your furnace is losing efficiency. As your furnace ages, internal components suffer more wear and tear. This makes your furnace work harder to heat your home, which increases your energy bills.
