Is your HVAC system broken?
If your air conditioning does not seem to be working correctly then you should contact one of the HVAC companies in your area right away. It is almost July so the temperatures are only going to continue to rise in the upcoming months. The last thing you want is to still have a broken AC system in the middle of August. It would be so hot in your home you probably would not even be able to stay there. So I highly recommend finding an HVAC contractor to come to your house and have a look at your entire AC system before it is too late.
Now, the best thing to do is to go online and Google HVAC contractors and you will be given a list of the best heating and cooling companies in your area. Simply compare the different companies and their services offered and then choose the one you feel is the best fit for you.
