Around $300- $5000, depends on whether you want single-stage, multiple-stage, or super quiet high-end ones.
Most popular brands have the same quality and warranty, but you should go with a contract who is professional and knowledgeable.
There are a few online communities where consumer can get some educated help.
First one is hvac-talk.com, which is a forum for HVAC professionals, but you can ask any technical questions and can get more informative answers. But the website does not allow to discuss the price or cost of HVAC projects.
The second is "Heating and cooling" forum of gardenweb.com, where you can ask technical question and also discuss the whether the cost and price of heating or cooling are reasonable.
The third one is
hvac-cost.com
where consumer can share their purchase price of HVAC system or search the database to see how much other consumers are paying for a similar system at the same city or state.
Cost may vary depends on the house size, accessibility, the amount of work involved in duct reworking, disconnecting/connecting gas electricity. Normally, it's better to replace AC/coil/Furnace all together, since a new furnace may not be compatible with old indoor blower /evaporator coil.
Typically needs "A" coil atop furnace in ductwork, large vapor and small liquid copper lines running between a-coil and external (outside) condensor/compressor unit, 220 V at compressor end, and a professional to silver braze the commpr connections, evacuate the system, and install the refrigerant.The all you need is a thermostat.
It depends on the size of the coil and the burn rate.
The answer is the drive shaft,strong magnet,and the coil of wire
Electromagnets are temporary magnets that are created when electric current flows through a wire coil. The strength of an electromagnet can be increased by increasing the number of turns in the wire coil, increasing the current flowing through the coil, or by using a ferromagnetic core material.
yes....just need to support evap coil and plenum while removing furnace and seal back up once furnace is set into place.
not very well. a 4 ton system needs about 1600 cfm to provide it's full capacity of cooling. a 3 ton furnace puts out about 1200 cfm. in addition, the evap coil typically attached to the furnace needs to match the tonnage of the outdoor unit. so, the evap coil must be 4 tons. If you currently have a 3 ton furnace and evap coil, the system will not work, and you will most likely ruin the compressor in the outdoor unit.
after (dowanstream) of the gas or oil-fired furnace
Yes they can. Furnace filters help to divert dust and keep your furnace and air conditioning coil clean. As long as it doesn't break, a furnace filter can be reused.
Yes it does.
simply by measuring the coil voltage, coil current & power factor.
With central air the furnace fan must be running to provide the air to the living space. If the furnace fan is not running then you get no air out of the ducts and the A-coil (the part of the ac system that is in your furnace duct) will freeze and shut down the compressor (the part that is outside).
Between $490-765. That's a range for a 2 ton to 5 ton residential a/c coil cleaning.
It is 2.5 ton with standard non-TXV evaporator coil.
Could be a drain for the inducer motor if it has one and it depends do you have a a/c coil on your furnace if so it could be a drain for it.
Exactly what I am doing now. My furnace is old and ineffiecient so I bought a new, ineffiecient furnace. (80%) natuaral gas. I also bought a cooling coil that fits on top (upflow furnace) of the furnace. I bought a condensing unit that will go outside and be wired to the furnace and thermostat and connected to the coil with refriderant lines. All of this was less than half of what an installer quoted for just a new furnace! The new furnace is the exact dimensions of the old, so it is a plug and play situation. However, I need to have a licensed plumber make the connections, which then need to be inspected by the town. I have an EPA 608 certification to make the AC connections, but that must be inspected as well. I have to run a whole new circuit (220V) to the wall where the outside unit will sit. So for less than $2,000 I will replace my old junky furnace for a new split system furnace/AC system. I also replaced my old thermostat for a new digital programable thermostat for $49. This should save $ as you can program less heat or cool when everyone is at work.
Yes you can do that. I had an oil fired furnace that also heated the hot water in a coil inside the furnace. I got an electric hot water heater and had a plumber disconnect the coil in the furnace and hook up the electric hot water heater. No problems after four years.
