Your cart is empty.At only 7-1/2" tall, these quiet yet efficient low-profile ducted furnaces feature multi-ported stainless steel burners, sealed forced-draft combustion, automatic direct spark ignition and low amp draws. With up to nine duct connection choices, these models offer almost unlimited design flexibility. The SF-FQ models do not require exterior access doors which make them the more economical installation choice. Suburban Q-Series furnaces have been redesigned to be significantly quieter. Increasing the efficiency of the furnace blower to deliver more CFM, allowed Suburban Design Engineers to lower the motor RPM to deliver the same amount of air but at a substantially lower sound level. Dimensions: 7-1/2" H x 17" W x 20" D

Loved it. It works and sounds better than the original.

Received my furnace quickly. I had questions about mounting and performance. Had problems with the first unit I got. They very quickly got me a new unit delivered. After it was installed properly it works wonderfully. The only issue I have is that sometimes when the thermostat kicks on the furnace dosen't start. I have to turn the thermostat down and back up and it turns right back on. It's a pain in the butt but sometimes but I'm incredibly grateful for the company's support and quick resolution to my issues. Only problem is there's no phone number to call. Everything was done through the Amazon app. Messages were answered quickly and accurately. Would definitely do business with this company again.

The case was bent, used the old one. Had to modify the gas supply line to the rear. Have used it 2 nights and it works flawlessly and quieter than the original. Thanks

Perfect replacement. Very awesome sellers. They shipped as soon as they saw my message on how bad we need it. Thank you so much!

My old furnace broke so I bought this and installed it very quickly. Started working immediately.

I am a retired HVAC tech and did installation myself. that being said, finally finished install.I ordered 4 duct collars, propane tank hose, didn't want to use a simple RV thermostat so I am using a 24V programmable thermostat via a 12-24V booster and a 24V SPDT relay. picked up 4" flex duct, registar boxes, metal duct tape, 3/8 copper tubing and flare fittings from local hardware store. installed in 14 square Tuff Shed. all powered by 12V deep cycle RV battery. A 12V PV with charge controller to keep battery charged. everything I used I ordered through Amazon (except the hardware store stuff and RV battery). works well, heats up shop in minutes on a chilly morning. got freezing temps forecasted for this weekend, so will see how well it preforms there, but expect good results.

Ordered this as a second heater from another vendor and it never worked properly. Even with numerous phone calls, I never got any help from seller or manufacturer. I will not order from this vendor again.

Love this new replacement. Replaced old style Suburban Sf-25F heater that we have had since purchase of 1999 Sportsman travel trailer in 2000. Have replaced motor 3 times and in shop work one time. This is soooo quiet and blows more through vents than original when we first purchased RV in early 2000. The RV had barely been used and looked brand new so we know heater had no excessive use. (Was originally first titled and tagged in Texas which is where we also purchased.) Highly recommend and the price was spot on for what we were willing to spend.
