I'm not allowed to give you the answer but mine uses low stage.

The following is just my opinion and should not be construed as professional advice: The metallic sound you hear is the spirals making initial contact upon starting and is considered normal by the...

Had a similar problem with my new Trane unit. Installers replaced blower motor AND blower wheel. Problem solved.

I use a Merv 8 in my new system. Honeywell filters are available at Home Depot at a reasonable price. I change the filter every six months.

You need to get your installer to check the dip switches on the control board of the XV95. It has to be set for "Comfort R" in order to ramp up and down.

I used a Honeywell EAC for 14 years until the power supply started getting weak. I switched to a 5 inch media filter because I was tired of washing the EAC cells every month. Media filter is much...

If the unit is still under warranty I would have your HVAC company relocate it for you. Mine was just wire nutted in the condenser. I unhooked the sensor from the wire nuts and then hooked up a two...

Relocate the sensor away from the condensing unit. It's not going to be accurate inside the cabinet or near the line sets. When relocating it make sure it's not influenced by the discharge air from...

In your situation I would stick with the 4/5 inch media filter. You can purchase a
two pack of Honeywell Merv 8 filters at Home Depot for a very reasonable price.
I previously had a Honeywell EAC...

Possible cabinet vibration? Temporarily loosen some of the exterior cabinet screws to see if that makes a difference.

Just a thought. I believe you said you have a heat pump so you might want to have your HVAC company check to make sure the heat strips are not on while the A/C is running. That could account for the...

I had a similar problem with a new XV95 furnace. It whistled from day one. Finally, the installer replaced the ECM blower motor, controller, and blower wheel under warranty. Problem solved.

Where I come from,"Factor into the equation", means a calculation. Sorry if I confused anyone.

Do you think you might want to finish some of that basement area into living space some time in the future? If so, I would factor into the equation some additional capacity to handle it. Cooling...

Only other thing I can think of would be to take the condensate line apart and see if there is any nasty stuff laying in the pan under the coil. Maybe suck it out with a wet vac. Like others have...

I have a unit with a scroll compressor and it makes some noise on start-up and shut down. I had an OEM start kit installed and that helped considerably with the start-up noise and it lowered the...

I had a Trane XL15i installed last August. It's quiet when running but noisy on start-up for a few seconds. Better listen to one before you buy.

Walmart sells some of those real soft foam ear plugs that work pretty well also.
lol.

How far away from the coil was the "nearest supply vent"? You need the check the air temperature about a foot after the evaporator coil to get your best reading. With humidity levels that low...

Most Scroll compressors I've heard make a loud buzzing noise on start-up for about two seconds or less then quiet right down. This is considered normal assuming the refrigerant charge is correct. If...

Sounds just like my Trane Xl15i when it starts after sitting idle for a while. During subsequent cooling cycles it's much quieter on start-up. It also has a scroll compressor.

Post your problem on Don't post links to other forums, read the rules, its not allowed.. You'll probably get some answers there.

Here's a few negatives for you:
1. They're ugly.
2. They rust and seize up after a few years of service.
3. The rust runs down and stains your shingles.
If I were doing it I would install powered...

At the time I couldn't afford the whole package. The XL1200 performed wonderfully using the Lennox coil for the next eight years. Then, natural gas became available and I replaced the Lennox air...

How certain are you that the compressor is bad? Did someone ohm out the windings?


We don't post DIY instructions here, please read site rules, thank you.

Yes, you can connect different...
