Does your furnace sound like its working fine but you still aren’t getting enough heat in your home? This was the problem we were having and after a service call from an HVAC repair technician in Canada, we learned that our blower fan had to be replaced. This prompted us to do a lot of research to find the best replacement furnace blower fan. We even got to test a few ourselves.
The following article details our experience with three of the best-rated furnace blower fans currently on the market in the US and Canada. But if you don’t know what the job of a blower fan is, allow us to initiate you before we get into our reviews. The blower fan is essentially there to disburse the conditioned air that your furnace creates. So when your blower fan is blown out (no pun intended) or is otherwise not working properly, your home may not be getting warm air circulating in it. The furnace itself may be fine, but you may need to replace the blower.

The Dayton 1TDR9 is a permanent split capacitor blower fan which means that there is no switch needed to run the motor at different speeds. When the motor starts up, it can run from startup to running capacity without any additional circuit shifts. Our HVAC guy actually recommended this Dayton model furnace blower fan to us because he says they are very easy to install. In fact, I looked up a YouTube video for it and was indeed, able to replace it myself.
The frame of this blower fan is made of aluminum so it was built to last. The fans are operated on ball-bearings and in the time we had it installed in our furnace the Dayton 1TDR9 ran very smoothly. And this thing moves a lot warm air. In fact, it is rated to achieve a maximum ambient temperature of up to 104 degrees Fahrenheit. And while we didn’t have cause to use it for vacuum pressure, our HVAC guy informed is that it can be used to cool down engines and heavy machinery as well as for generating vacuum pressure.
- Easy to install
- You don’t have to oil it
- Works on a variety of furnaces and hot blast stoves
We were told that this specific model of P-Tech blower could work as a replacement for our busted furnace blower. So we tried it out and were very impressed with the way it worked. It actually made our furnace quieter! And it provided ample warmth. The P-Tech 3.3 inch blower can reach a maximum of 273 CFM (Cubic Feet Per Minute) which is a measurement of how much air this blower can move in a minute.
Our HVAC guy informed us that he uses this specific model quite a bit in his work because they are a proper replacement for a wide variety of furnace blower fans. And they can be used to ventilate greenhouses, for heating and cooling applications, fireplaces and many other applications. Overall, we were quite impressed with how silent and powerful this fan was.
- Runs very quiet
- Doesn’t draw too much electricity
- Can be put towards a number of practical applications
We end our list with another entry from P-Tech and another permanent split capacitor type blower. After using this blower in our furnace for a week, we can say that this little motor was convenient, fast and provided enough warm air for our entire home. The split capacitor feature makes it a breeze to use too. Although, it should be noted that it cannot be used with speed controllers as it operates at a single speed at all times.
That being said, this 1/125 Horsepower blower doesn’t really need to operate at any other speed than the one it comes factory set to. It seems that the P-Tech Round Permanent Split Capacitor 3.3 Inch Blower was designed specifically for residential use in furnaces because it was perfect for our mid-size home. But obviously, that’s just the way it seemed. Our knowledgeable HVAC tech informed us that this model can also be used in a variety of other ways.
- Can be used to replace Dayton and Fasco blowers
- Operates at 50 CFM
- Ample residential heating
