    I personally like Lennox better than Bryant. As a tech, if you understand the sequence of operation(s), you should be able to work on anything. Depending on the contractor, parts may or may not be...

    I think there are some other things you need to consider. What part of the country do you live in? If you live in a heating climate, invest more money in the furnace. If you live in a cooling...

    How were you able to determine what the RPM of the motor is? One thing to keep in mind when replacing a motor, the HP doesn't mean as much as the amp draw does. To save yourself time and money, you...

    My suggestion would be, depending on the humidity in the home, to run the blower continuosly. This will help circulate the air in the entire home and will help with overall comfort. It can help to...

    It's an honest mistake. Sometimes the best lessons learned are the hard way, so you may have made the mistake now, but you probably won't do it again. I had a guy tell me once, "you find me a guy...

    Makes no sense to use a larger lineset. Makes no sense to enlarge the 3/4 pipe. They make these things called reducing couplings or a reducing bushing. I prefer the bushing. It's a 3/4 coupling X 7/8...

    If you're not willing to run the A/C any more than what you've indicated, you're fighting a losing battle. With such short run times, there is no chance the humidity will ever drop in the home. If...

    Make sure all of the ductwork located in the attic is intact, especially the return(s). If the return duct is not tight, there could be warm/hot attic air being sucked in. Double check all of the...

    My guess is that you've got a large enough leak that you lost enough refrigerant that it's causing problems again. How many times have you had to have refrigerant added to the system? Are you sure...

    Aire Flo is manufactured by Allied Air, which is owned by Lennox. They are a builders grade equipment line, but they're not too bad. Our company installs quite a few Aire Flo's and Concord's(Concord...

    Your location is going to play a factor in your decision. If you live in a heating climate, I would recommend replacing the entire system. Life expectancy of a furnace(in a heating climate) is 15-20...

    Is this a manual J load calculation or a "rule of thumb" chart that you're talking about? If it's not a manual J load calc, it's worthless. Every home is different and requires different sizing based...

    If you want your home to be energy efficient and save yourself money on your heating and cooling costs, yes. Thankfully I live in a climate where you'd be foolish not to have insulation in the walls....

    Your money would be better spent by tightening up your home's envelope, which would include insulating the walls. Then you wouldn't have to oversize the A/C and would help reduce your overall energy...

    Regardless of what equipment you go with, they'll all have R-410A refrigerant. Where are you located? 4 Tons of cooling for a 2064 sq.ft rancher sounds oversized. I'm sure the walls have some amount...

    Seems to me it would be cheaper in the long run to just fix the leak rather than pay to gas n' go every year.

    Here's my suggestion. If you're not sure if you have nitrogen in the system, recover the charge, evacuate the system and recharge with virgin 22. Then see what happens to your pressures. As was...

    Believe me, you're not making him rich. Unless your "friend" is willing to come and replace your coil, he should keep the prices to himself. Unless he's seen your install and knows what it's going to...

    First thing you'll want to do is delete your pricing as they are not allowed in this forum.

    A lot of times it's not cost effective to fix window units because the repair costs can sometimes be more than a new unit. Did you weigh in the charge?

    A manual J load calc determines what the heat loss and heat gain are for the dwelling. After knowing what the heat gain/loss is, then the size of the equipment can be determined, so that you don't...

    The system can be tested to see if/how much moisture is in the system. If the tech is going to condemn the system due to a leak in one of the coils, then he should have no problem getting warranty to...

    I would say that if the evap coil is in fact leaking, and it is covered under warranty, then I would replace the evap coil. I don't think there is really any reason to replace the condensing unit...

    For me personally, I would go with metal pipe instead of flex. Flex duct has it's place, but if it's not done properly, it will never work right. I would also have ducted returns instead of a central...
