cooling

  1. HVAC
    What are the most efficient options to maximize cooling & ventilation in a 200 square foot room with only 1 (23"x 35"h)window that opens? The problem gets worse during the summer as there's no cross ventilation. There's an additional window on the opposite wall that runs just below the...

    First off, I really hope this is some insulation and not what it kind of looks like. How much if any is it affecting the cooling when the ac is on?

    I have a home and HVAC system only 2 years old. The unit does not cool. The condenser and fan do not come on. I have replaced the contactor, and it does not seem to have fixed the problem. I have checked the capacitor and it is fine. Also I checked the thermostat and it was working fine, I...

    Hello, Forgive me for my layman's terms. When my a/c unit is on the air blows straight out towards nothing. I have to stand in the pathway of the air to cool down or have my thermostat on 60 to cool down the whole room. Is there an affordable fix to redirect the air towards the couch vs. the...

    Hey everyone, Just in time for a heat wave, our a/c went out today. When I went to turn it on for the evening before bed, it wouldn't start. The fan is not coming on at all. I looked at the fan outside, and it looks like the capacitor is old and rusted over. But, it doesn't sound like the...

    I'm considering removing the 2x4 t-bar grid ceiling tiles in my commercial retail store. I am getting the space renovated before our store opens next month. - Will this effect my heating and cooling costs? - Do ceiling tiles on a "dropped-ceiling" help keep heating/cooling costs down? The...

    EDIT: Moved this to HVAC section,,,,not sure how to delete. We moved into a large home a few months back and right off the bat had some problems with the zone dampers for the the main floor. The dampers are the rectangular blade type and almost all of them are malfunctioning due to worn...

    Would a 9,000 btu minisplit unit be enough to heat and cool a 200 sqf room easy, fast, and efficiently?

    Our 18 year old ClimateMaster 2 stage GEO heat pump just got 2 new compressors and 2 new dryers and both stages got a new load of R-22. Tech (12 years experience at a big commercial/residential company) ran unit for about 30 minutes after the repair and both stages looked good with no leaks. He...

    Hey guys! It's me again. This thread is a little different from last time. I had a "specialist" come in an install a duct fan. The friggin' thing is so loud though! Now, the air comes out of the vent full blast (almost) but the air isn't that cold at all compared to the northern rooms. I don't...

    Problem: Our second floor is an "A" frame without an attic. We have one air return vent over our loft which connects to our large bedroom/bath and a large room over the garage. There are doors between the 3 large areas. Our bedroom in the middle gets no air flow and is hot in the summer and...

    Ok so the short and skinny of it is that our A/C (Goodman GSC13 Air Conditioner) is not living up to its expectations, like keeping the house cool. Although we do live in Arizona where 100 degrees is considered normal I would at least expect my A/C unit to keep it at least 80 degrees in the...

    Hello, So I bought my grandmother's old home a couple years ago. There is a room that was an add-on which was used as a sun room. It was built before she moved in about 10 years ago. In the winter we freeze and in the summer we fry. I've identified a lot of the issues, i.e. door leading to...

    greetings all, I am getting ready to build a new shop building...60' x 100'. I have this idea about a diy geothermal system and wondered if any of you had any thoughts on it. What I am thinking is to bury a 6-8" solid plastic tile about 5-6' deep and circulate air through it to partially...

    I live in a concrete condo and the front of our building stays very very hot. Other people in these units have replaced their ac units but it still is hot in the front of the bldg. :furious: I think if we insulate the front walls with some sort of spray foam...behind the drywall by drilling...

    I just got a new Trane system installed last year thinking it would help but it has made no difference. I have gone back and forth trying to figure out why my house will not stay at a comfortable temp in the extreme summer/winter months. I have an old brick home with what I assume has no...

    I had the mercury type thermostat and changed it out for a touch screen. It works fine, but my question is, why do they seem to put these in a hallway which has no vents. I have the unit set to only run after 2 degree out of range of a set temp of 72. We have our attic steps right above this...

    I have a heat pump on the outside and a unit under the house, which I assume is called a split system (help me)... We have the antique looking thermostat installed now. (all manual) I purchased a new Hunter touch screen 44905. I removed my old and noted the wires. I installed the new one and I...

    Hello, I have a raised house in New Orleans and are looking to do Geothermal, radiant heating, and if possible radiant cooling. Does anyone know about if radiant cooling works with a geothermal system? And does anyone know if you can hire a driller to do a system that isn't the same guy who...

    Right before my unit stopped cooling I had the temp on a normal setting I always have it on. All of a sudden it got really freezing, ice cold, in the house. I turned the system completely off, when I needed it to cool again and tried to turn it on- the outside unit, blower, fan, everything...
