This offers a platform for business to post their own evaluations and people to hastily post reviews without the business in question's ability to expertly solve the issue.

Frequently Asked Questions:
What Is Vav And Its Function In Hvac???
The Above Is Used In Ducted Air Condition Units
A laboratory-type facility has stringent air-flow requirements to create a safe, constant, controlled environment. Additionally, laboratories have areas where air volume and temperature must be adjusted according to occupancy. In either new designs or retrofits, VAV systems can make HVAC systems operate more efficiently to meet these needs.
When a facility is only partially used or occupied during the day, the VAV system has a high, part-load operating efficiency. In order to achieve additional energy savings, the VAV system reduces the average ventilation rate in laboratories when they are unoccupied.
A VAV system also has other advantages: it monitors and controls pressurization in laboratories for increased safety, it readily adapts to adding or moving fume hoods around during remodeling, and it improves fume hood safety monitoring. The advantages of the VAV system make up for the fact that the system may not have the lowest first cost.
What Is The Savings I Could Expect When I Use A Heat Pump Instead Of A Gas Furnace?
I Live In Ne Pa And Am Trying To Compare With A 90% Furnace.
Unless you go with something like a groundsource heat pump, you'll be mostly heating with electricity all winter if you do the heat pump --- once temps of the source of the heat the heat pump is extracting drop below 0oF, they're just the equal of running electric strip heaters. When temperatures outside are fairly warm -- for instance, here in western Or valleys, most of the winter we've got temps in the 40's-- we get about twice as much heat per unit of electricity used if we use an air source heat pump instead of an electric strip heater. That difference is called COP, coefficient of performance. The closer the indoor and outdoor temps are together, the better the COP, up to 3 or 4. When you get down to around 0oF, COP is about 1 for a heat pump (and not a whole lot better than that around freezing!)
I would bet your local power company can calculate the costs of a heat pump vs. gas furnace, given your power usage for the last few years. My guess is the gas furnace is going to be the winner here when costed out over a reasonable period of years.
The other advantage of a heat pump is that it can also be used as central air conditioning in the summer -- that's an add-on to a gas furnace. You may want to include that in your calculations. Or not.
Re-Charging Air-Conditioning On 2001 Passat?
I Just Bought A Recharging Air-Conditioning For Dummies, And I Have Done A Recharge Before But On A 97 Saturn. I Found What I Believe To Be The Low-Side Port That It Needs To Plug Into And When I Try To Plug It In It Appears As If I Does Not Fit And It Sprays The Coolant From The Port All Over The Place. Am I Doing Something Wrong Or Is Does The Gauge That I Have Not Work On My Car?
If the ports don't match, quit trying something is definitely not right. Make sure your compressor is free and the expansion valve works. If it doesn't take the charge, most likely expansion valve.
How To Clean The Air Conditioning In Ford Fiesta Date 2000.?
When Air Conditioning Starts There Is An Awful Smell From The Air Vents In Car. Goes After A While But When I Start The Car Next Time The Smell Is Awful For A While Even If Air Con Is Off. How Can I Disinfect The Air Con?
Sounds like you have mold in the evaporator. You can get a spray solution at auto parts stores that you can spray in the cabin air intake (where your windshield wipers are) that will kill it. Another solution is to let the heater run for a few minutes each day since heat will kill mold.
How Do You Install Central Air In A Home That Is All Electric Baseboard Heat?
Our Home Is Entirely Heated With Electric Baseboard Heat; Therefore, No Duct Work For Forced Air. Can We Install Central Air And Still Keep Our Heating Method By The Electric Baseboards? If So, How? Any Help, Web Links, Anything Would Be Appreciated! Thanks
They have to install duct work if they can in an attic or basment/crawl space area and the grills would be in the attic or basement. Air conditioning must also have a return air system so there would be return air ducts installed with the system and some rooms would have the air vent and a return air vent. This is very expensive to do.
There are some new systems out that offer small units that can be placed in rooms that don't have to hang in a window and are not bulky. It is worth talking to a reputable company about you options.
