HVAC-for-beginnersHVAC-for-beginners will discuss the electrical hookup for HVAC, the ductwork, the furnace and the air-conditioning system which are all part of HVAC. If you are told you need an “Energy Efficiency Evaluation” then your HVAC contractor can get it for you. Your home can be heated by various sources. There are heat pumps, solar units that fit on top of the house using the sun's rays, electricity and gas that can be used in the heating of one's home. We have experienced using electric space heaters,and the units that go under the windows,for 18 – 20 years when the children were young. Our last home was heated by electric cable in the ceiling. Until we put a tinfoil like barrier in the attic, there seemed to be a loss of heat out the attic. We feel the distribution of air is not as complete as a forced air furnace. Our family was always getting ill during those years of using the space heaters and ceiling cable. We reasoned it out as to why we had so much pneumonia, etc. and that could have been that air was not circulated and kept freshened. That's our opinion, solely, so take it for what it is worth. Our choice for HVAC-for-beginners in this house is the gas, forced air furnace. We've had it before the electric heating, and are enjoying it again.
The HVAC-for-beginners sub provided our furnace. If you purchase it, you have to have it delivered at the right time. Like the sealant sub, he has a lot of leftover materials for venting and ductwork, so we just let him supply everything. We reasoned that if he supplies it, then he carries it in and we don't have to worry about that. It's heavy, we're older and RL's heart couldn't handle it. In your contract with the HVAC man you'll want to have him include how much money he needs up front, if he supplies materials. We paid 3 different payments to him. 1. When he delivered and installed the ductwork 2. When he installed the furnace 3. When he installed the air conditioner, thermostat and did the final hookup.
When does the HVAC sub come?HVAC-for-beginners can come when framing is completed. The house needs to be pretty much enclosed with all the walls in place, upstairs and down.
First the HVAC sub will put up the duct works and that includes return air ducts. Then just before the wallboard is put up the furnace will go in, This is especially true if you are dealing with cooler temperatures as wallboard mud has to be kept warm.
Changes and HVACChanges that we made to our house really messed up the HVAC contractor's routing of ductwork. He reminded RL over and over that on our next house to be sure and consult him as to where to put the furnace room in the basement. 
This is the cold air return duct that is actually placed on the opposite side of the support wall than the furnace room. If we had consulted with the HVAC sub, we'd have designed the basement so the furnace could be on the same side as this ductwork. Try not to make changes if they can be avoided, but if you do, the HVAC sub may need to be consulted. Our problems were related to having a basement, and where the stairs were and where the furnace was placed in relation to the stairs. Crossover from one side of the house to the other is a big consideration. We ran into some major problems, because we didn't plan this in advance. Our HVAC sub was pulling his hair out with frustration due to several reasons: Where we placed our furnace The direction the stairs went Where the ductwork crossed over to the other side of the basement. Talk to your HVAC-for-beginners sub early on and address all these issues with him!!! He can save you some money, and save himself from headaches untold.
Other things to considerLook at where your cabinets and furniture are going to be placed in the house and then position your furnace air registers so they don't interfere with your permanent cabinets. Cabinets can have a register hole cut for a vent in the bottom kickplate if necessary. If you have your furnace running during the drywall mudding, be sure to change the filters often. This will keep the dust that results from the wallboard mudding and sanding from clogging up the furnace filter and ultimately that new furnace. If you have to heat the house in the winter, an area space heater run by a generator is preferable, to save the life of your furnace, not to mention the savings from having an exorbitant heat bill. Lock it up and keep it.It's a good idea to get your doors and windows in place so you can lock up your house and consequently don't have materials disappear at night.There are so many thieves who watch for unlocked new construction homes that they can pilfer and steal items that are left out and unlocked. I know of one couple who lost several hundred dollars of electrical materials, including copper wire. Copper wire brings a large return to the thief. It isn't good enough to get your garage door installed and leave appliances and other things in the garage, or so I was told. Some shady construction workers keep their eye open for just things like that. The garage door is left open during the day, and often things will disappear during the day.
