Is it too cold outside to run my AC?
I’m new here and hope that you can help me with some questions.
I just had a Heil H4A836GKD / FVM4X4800A (3 ton) installed in my home at the very end of March. A couple of weeks ago it was fairly warm for April in New England and our inside house temp was about 75 degrees. Outside temp was about 63-65 degrees maybe slightly lower. Because my wife has bad allergies and I was anxious to try out our new AC I decided to turn it on. It came on for about 3 minutes and then it turned off for about 2 minutes and then it came back on for about 5 seconds. This cycle of off for about 2 minutes and on for 5 seconds continued. I had my AC on but my house was getting warmer. I went on the internet and what I read made it sound like it was cycling and the it was best for me to turn it off and call the company who installed the unit. So I turned it off and called the installer on Monday (this all happened Friday evening. It was by no means an emergency so I waited until Monday to call).
We were told they could come out in a week and a half to test it – this was a little annoying considering we had paid good money for this and the first time we go to use it it did not work – but it is not the heat of the summer yet so I can be patient. They were supposed to come yesterday but they called and said it will be too cool for them to test because it is set up to not operate below a certain outside temperature (it was only about 60 degrees for a high yesterday maybe not even quite that high).
Here is where I am running into a wall. They either would not or could not provide me with the temperature below which the unit will not operate. They then they proceeded to tell me the day I tried to run it the unit it was probably too cool outside and that is why it would not run properly. Is 60* too cool for my AC to run?
Can anybody provide me with the temperature at which my AC will not run because it is too cool outside? And is it possible to lower this cut-off temperature if necessary? I ask because this could potentially be a problem for us because on sunny days our house can run 10 to 15 degrees hotter inside than outside and simply opening windows will not bring the inside temperature down to the outside temperature. Also as stated above my wife has bad allergies and one of the reasons we purchased the system was to try and keep the windows closed more to help ease her suffering. So it is conceivable that on a very sunny 70 degree day it could be 85 inside the house (that would be extreme but not beyond the realm of possibility). If we cannot run this AC at 65 degrees outside we could potentially have a system that does not fully meet our needs.
I have tried to find documentation for this system that would provide this information but have I have been unsuccessful.
I called yesterday and asked to speak to the owner of the business because his assistant initially called to reschedule because it was going to be too cool yesterday. They wanted to reschedule for tomorrow which seemed silly because tomorrows high looks to be very similar to yesterday’s high temp. I can’t keep rearranging my work schedule so I can be at home only to have them continually reschedule because it is too cool out. I just wanted to know when and how this would be fixed.
During our conversation he mentioned that the units are often shipped to them undercharged and that it may need to be charged. They were unable to determine if it was adequately charged at the time of installation due the low outside temperature (again it was March). He stated that when we get a day “warm enough” (I’m still unclear what warm enough equates to in degrees Fahrenheit) they could come evaluate the system and charge it if needed and this would most likely take care of the problem.
Does that sound reasonable?
I got the feeling he just wanted me off the phone and I don’t know if I should believe what he was telling me.
I want to believe him. He came very highly recommended and on the day of the install everything went very well and his crew was very professional.
So at this point I am just trying to educate myself as much as I can because he seemed unwilling to help educate me with regard to exactly how the system should work and what my expectations should be.
I am still hopeful that it will all be taken care of fairly easily but I want to be as educated as I can just in case he is feeding me a line of BS.
Thanks in advance for your help.
