What Your Neighbors Are Saying About Us

As a new home owner, I’m very glad I chose this company for basic maintenance. Justin was punctual, polite, and so helpful. I had a lot of questions, as I basically had 0 knowledge about HVAC systems, and he answered everything throughly. I’m happy to continue their membership plan because I know we’ll be in great hands once it’s finally time to replace the units.

The whole team at Self is wonderful- I’m so glad to have them on my side for all things heating and cooling. They are great at explaining everything in a way you can understand, and giving you options for your needs. Appreciate the team and highly recommend getting your HVAC serviced with them

Matthew may have been one of the most thorough and respectful HVAC technicians I’ve worked with to date. He was highly communicative, knowledgeable, insightful, respectful and efficient.

Safety comes first on gas equipment, so heat exchanger and combustion checks are part of the visit. We show you what we found in plain language and never talk past you toward a bigger sale.

Frequently Asked Questions

My furnace will not turn on. What should I check first?

Confirm the thermostat is set to heat and calling for it, check that the furnace switch and breaker are on, verify the filter is not completely clogged, and make sure the door panel is seated since many units will not fire without it. If those all check out, it needs a technician.

Do you repair all furnace brands?

Yes. We service electric and gas furnaces from Trane, American Standard, Lennox, Rheem, Ruud, Goodman, Amana, York, Heil, and the other major manufacturers, and we stock common parts on the truck. Repairs are warrantied, with terms depending on the service performed.

How quickly can you get to a no-heat call in Marietta?

No-heat calls are treated as urgent and same-day service is usually available. We schedule a two-hour arrival window and send a text and a call when your technician is en route. Saturday and Sunday appointments can be arranged by request, and Self-Assurance plan members are scheduled first.

Is it worth repairing an older furnace?

Sometimes clearly yes, sometimes clearly no. We look at the age of the unit, the cost of the specific repair, its efficiency, and how often it has failed before, then give you the honest comparison so you can make the call rather than feeling pushed.

Why does my furnace smell when it runs for the first time each season?

A brief dusty or burning smell on first startup is usually dust burning off the heat exchanger and should clear within an hour. A persistent burning smell, or any smell of gas, means shut the system down and call us right away.
