Q. Please anyone know the estimate? I have no idea and interested in getting central air conditioning system for my home...tks!

A. Trane and Carrier=You pay for advertising. I just bought a 3 ton Goodman for $1200 installed, outside unit only. Entire central air system with inside ducts, etc.: who knows.

Q. Should there be a small amount of water coming from the base of the unit inside the house? I can't figure out if it's the air conditioning unit or a leaking water heater?

A. No there should not...most likely the drain is stopped up and will need cleaning...this very easy and you can do it yourself ....just remove front cover of unit drain line should be visible along with two copper a/c lines...remove drain line ..flush with water hose ...run some bleach down it and reassemble....this should solve your problem...

Q. I have an outside central air conditioning unit, it is approx. 80 degrees outside and extremely humid, also very hot inside the house with fans running. The air is set to 70*, yet the air coming out of the vents feels to be room temperature and is NOT cooling the house down. Approx. two months ago, the landlord had a technician come out, and he said we had a slow freon leak, and although he filled it with freon, I was told he did not fix the leak. What is causing the air conditioner to do this? I cannot go in 100* weather without air conditioning. Any help would be appreciated :) and thanks in advance!

A. It almost sounds like the tech overcharged the unit. Either way he is supposed to fix the leak. He was not supposed to add refrigerant to a system known to be leaking. Make sure the fan is working on the outside unit. If it is not the system has no way to remove the heat from your house. Ask your landlord to call a different tech out to look at it. This guy was a fool.

Q. I am trying to find out how the sanitation process works and if it causes chemical smells in the house? I'm starting to use the air conditioner in our new apartment and everytime it comes on I end up with a headache and the air smells musty. I have been informed by the air conditioning company that it needs to be cleaned and sanitized, I am concerned about the chemicals they will be using as I am senstive to chemicals. Anybody have this done before and know how it effected your home?

A. I have asthma,allergic to dust. We had our furnace ducts/pipes cleaned out ! I had no problems. The ho user is 6o years old. I do not think the pipes were ever cleaned. You should have no problem if it is a repitule company

Q. The central air conditioning in my apartment is getting repaired and won't be working for 4 or 5 days. I want to improvise something. Maybe taking a fan and pointing it a a bag of ice. Heck.. I don't know... Any tips ?

A. Use the principle of evaporation. Depending on the humidity, it can work wonders. Lightly soak and wring out a sheet before bed, and have a fan blow across you. You will be comfortable enough to get to sleep. Some people get a large amount of ice, put it in a shallow pan, and have a fan blow over it. Another is to fill an ice chest with 70% ice and 30% water, take a hand towels, soak and wring out, then place over head and breathe the cold air. Do it once more but this time leave on your wrists for a couple of minutes. As for a whole house fix, there is no other DIY method I know of. The ice cold towel on the head is really amazing relief even though temporary.

Q. It is 90 degrees in our house and only gets hotter they said they won't come until tomorrow afternoon. I work from home, I have a very ill dog, and these are not suitable living conditions.

A. Generally not. Obtain a court order first, you can not just decide to withhold rent. The dog will not be a legitimate reason in court, a signed lease and your AC being out for more then a couple of weeks will though. That is if the AC is covered in the lease. The next day is certainly not a problem for any reasonable person.

Q. My wife and I purchased this used house about a month ago. Before the purchase the home inspector alerted me to a leak had been repaired hours before his inspection. The repair was at the elbow of a drainpipe coming from the bottom of the air handler, going through the crawl space, and exiting into an adjoining wall. After moving into the home, I began to smell a damp smell coming through the air duct when the air conditioner was in operation. In addition, all three of us have quite sensitive noses and began to show signs that something was amiss,. I began to inspect, looked into the crawl space and found no evidence of a current leak but there was a lot of dust, dead cockroaches, and a similar damp smell. I also took the panels off the air handler and noticed mold all over a motor, which I suspect, is the blower and one side of the evaporation coils. Since this is a 3-ton system (the a/c is a fifteen year old Ruud and the air handler is an old Tempstar) in a roughly 2,100 sq/ft home in Mississippi, I was seriously considering replacing this system in a couple months. The system is cooling but does not cycle as often as I think it should. I have been all over YAHOO! asking questions so I know many of you are tired of reading my posts. I had planned to order a system from an online company called Alpine and getting a contractor to install it. Now I am assuming that my air conditioning ducts may need cleaning too and it may be more prudent to pay retail with a local company that not only installs systems but also cleans air ducts. In an effort to improve the air quality a bit, I was thinking about getting a mask, shop vacuum, gloves, bleach and water solution, sponge, and evaporator coil cleaner and cleaning the coils, blower, and crawlspace until we are ready to replace the system. Am I correct in my assumptions can anyone give me prudent advice?

A. You will receive the best answer from a HVAC (heat ventilation and air conditioning) contractor.
