Questions About HVAC

Insulated Garage Doors for Heating & Cooling Assistance in Ogden, Utah

Our triple-car garage in Ogden, Utah, faces west. Even with ceiling and wall insulation it gets really hot in the summer and really cold in the winter. We'd be happy with around 83 degrees in the summer and 50 degrees in the winter. Would it be more cost-effective to install through-the-wall heating and cooling units or to purchase insulated garage doors?

Separate Heating & Cooling for South Dakota Guest Rooms

For the home we'll be building in Rapid City, South Dakota, we'll have a central heating & cooling. However, the guest wing has two bedrooms with a shared bathroom. We estimate we'll have a maximum of 20 to 25 days per year of guest use. Is there any savings over a 10-year period in having a separate heating & cooling unit for that wing?

Creating Room Additions Over Bangor Garage

Our Bangor, Maine, home is a typical two-story saltbox with an attached one-story 22' x 22' garage. We'd like to extend the second floor out over the garage as a recreation area with an 8' x 16' hobby room. We have an asphalt shingle roof. The house is older, so framing is 2" x 4". Heating is by a fairly new boiler system. What type of heating do you recommend, and what's a ballpark price per square foot for these room additions?

Which Saves More on Heating & Cooling: Wall Insulation or New Windows?

50-year old home in Denver, Colorado, is of 2 x 4" frame construction, and has eight single pane windows. What expenditure will improve my utility costs more--having the walls and attic pumped with insulation or replacing the windows with good vinyl double-pane windows?

Heat Pump Installation Costs for a 1950’s Ranch House

I have a 1950's ranch that does not have central heat and air. I would like a ballpark figure for installation. It has an attic (which is pretty much fully floored and great for storage) and a crawl space which you do crawl in to navigate it (don't know if there is enough room for ductwork in there). Currently it has a hot water system and registers to heat the house (there is gas to heat the water). I don't know if a gas system (since there is already gas available) would be best and more cost efficient or if an electrical system for air and heat is best. I would also need ductwork installed. Thank you

Which is the better insulation option for me?

My heating and cooling ducts run through my attic. I'm looking to add more insulation to my attic. So which kind and style would work best in my situation (spray foam, spray loose insulation, or both? Best bang for my buck and best energy plan?

Adding an Air Condition Vent to a Room

I wanted to know the approximate cost to add an air condition vent to a bedroom that only has one a/c vent at this time. It gets too hot in the summer, compared to the rest of the house. It's a one-story house and the attic is fairly easily accessible where the vent needs to go.

Cost of Putting in Central Air

For years we've tolerated the heat here in Napa with a swamp cooler and now I want to put in central air. The home is a 1950s ranch style house. I'm a rookie in home additions or improvements. Can you tell me the cost of installing central air and whether it affects the structural integrity of the roof or other parts of the house?

Should I swap my conventional water heater for a tankless one?

I have heard that tankless water heaters are more energy efficient than conventional ones. Is it worthwhile cost-wise in the long run to replace my conventional one with a tankless in my North Carolina, home? Would I need only one? Where would I install it? What kind of savings could I expect on my utility bill?

Any suggestions for green HVAC system in cottage addition?

I have put in a small addition to our vacation cottage in Myrtle Beach. The summers are warm here, but sometimes the temperature does dip down into the 40s at night in the winter. We have a small fireplace in the main part of the cottage, but in the addition there is no heating. We'd like to add a small solar panel to the roof that is attached to some kind of HVAC system for the addition to keep energy costs down. Do you have any suggestions on how we can do this?
