Hi,

We recently bought a new house and are having a problem with our heating system. The air upstairs is significantly colder than downstairs, in fact you can feel the change as you go up the stairs. The air coming out of the vents upstairs is about the same as the cool room temperature. Downstairs is relatively toasty (we keep the heat at 65) and it feels like summer if you stand under one of the vents when it's blowing.

Any things we should try ourselves? If not, what type of professional do we need to call.

As much as what is going on there You need to call A HVAC contractor. Their's air returns involved here maybe "balancers" Needed for the balancing the air flow to equalize the CF Ms on the what runs. What size the runs are is it flat oval or oval or wall stacks. Just to give a prime example A 6" 90 has the same airflow resistance as 10' of a 6" straight pipe. Sorry Its one of those things Where a whole layout of the House and system is needed to start to resolve this problem. Call 3 Contractors and they can size the heat runs and air returns In the mean time see if the ducts to second floor is protected from the cold and that's the chill factor.

New house? New equipment? Warranty? Two systems?

Call the builder.

The best solution would be to have a HVAC contractor install a zoning system. That way you'll have separate control of each space, an upstairs and downstairs for example. Any number of spaces can be zoned.

Thanks all! I'll look into finding a contractor this week. The house is new to us, but 4 years old, so warranties are up.
