You need to take into account the loss of cfms due to the run of the duct system too. Thirty years ago it was all a big secret on HVAC systems, now you have the internet. Research, research, research. Setting vents properly in rooms determines airflow also. The room closest will get full pressure, so you adjust the vent. That's why there is an adjustment either on the primary vanes (hard to see) or secondary vanes (obvious).

OP, if your temperature numbers are correct, there is a serious problem with the installation of your system. The builder does not design HVAC systems with that much deviation in room temperatures. All rooms in the house should be within one degree of the thermostat setting. You need to have the entire system inspected before trying any of these suggested fixes. You do not need any Ecobee sensors.

You need a non-contact digital laser temperature sensor gun. They can easily read the temperature of air coming out of the vents on a high ceiling or read the surface temperature of the walls, ceilings, or anything in the room.

All you do is point it at the surface and pull the trigger and it almost instantly displays the temperature of the surface you pointed it at. It's very simple to use and easy to read.

Below is a link to one like I bought about 10 or 12 years ago. It works great. There are less expensive ones for sale also on the same page on Amazon.

Yes, cancel the duct cleaning! The villa is only six years old. Changing the filter to a Merv 8 might help air flow and closing supply vents in the front bedroom/bedrooms if not being used. From personal experience the master bedroom in a CYV is always warmer by a few degrees. I have even seen one that has no supply vent in the master closet .

One the bedroom door has to stay open unless you have a return in your bedroom..
Second, like others have said, check the insolation above your bedroom. If that's not an issue you may need to spend some money and re duck you home system and move the thermostat near your master bedroom.

Or an easier solution would be to install a split AC system just for your bedroom. Then you could keep your bedroom at 68 at night while the rest of the house is at 78.

We have the same house as you but it faces the opposite direction. My master bedroom is also warmer but only slightly. Since our guest room, the one nearest the laundry room is the coldest spot in the house we adjusted the airflow in that room to be almost closed and it helped the temp on the master. Just food for thought. We rarely use that bedroom anyway.

My master bedroom doesn't actually have a return duct, but there is a ceiling vent that transfers air into a duct above the bedroom ceiling to a ceiling vent in the living room, which then allows the air to flow through the living room and into the large return vent in the foyer area.

Strange yours is hotter.

Insulating garage doors make sense. It makes absolutely no sense to insulate above the garage because it will only make the garage hotter unless you add AC. Heat rises.

It does make sense to have a temperature gun but that may not tell her anything if it is an air flow problem because the temp.should be similar.

[Marathon Man]

I agree with the others. Duct cleaning not needed unless someone scopes it and sees the dust built up so bad that it hinders air flow. I don't see that happening in six years. Cancel the cleaning and spend the money having Sun Cool diagnose the problem and come up with a real fix.

Good call.
I would suspect some kind of blockage. Not dirty ducts. Also, would be nice to know if the ductwork was sized properly. Or if there are any diverted valves that could be out of position. Unbalanced airflow.

Had the same issue in our new home. The Villages sent someone out and verified the AC was cooling properly. I then asked them to go in attic and verify there was insulation above that bedroom. Come to find out absolutely no insulation in the ceiling above that room.

We had a similar problem in our 1st home in TV, which was a designer (Gardenia). In our case, it was a new home, that we moved into in December. One bedroom was consistently 5° colder than the rest of the house. All other areas in the house were within 1° of each other. We called Warranty about the issues, and they promptly sent Munn's out to investigate. After checking the output air temps at all registers, which were all good, the tech broke out his thermal imaging camera. He found that the bedroom in question showed very obvious cold areas on the ceiling. Specifically, the area from the outside wall about 3' into the room was noticeably colder. A trip into the attic confirmed there was no insulation blown in the attic from the outside wall, to nearly 4' into the room, for the entire width of the room. Two days later, the insulation contractor was on site to correct the issue, and the problem was instantly solved.

Long story short, even though Warranty may not apply, call a reputable HVAC company and have them do a thorough inspection. There is no way a 6 year old home should need to have it's ductwork cleaned.

OP, to check your bedroom for insulation, you may have an attic access panel in your bedroom closet. If so, lift up the panel and shine a flashlight across the bedroom ceiling.

If you don't get relief via AC, I would recommend a fan. I like the 'white noise' effect for sleep, and it does help me feel cooler.
