  • Project Location: Dallas, NC
    Hello, recently I had another business come and replace a fan motor and blade on an HVAC unit. It is now been making a very loud noice when turned on. The other business said they tried everything to quiet it down but they couldn't stop it or make it quieter. How much does it cost to come and look at the unit?We do need to replace our units they are 20 years old but I am unsure we can afford it right now. Thank you.

    I was interested in obtaining an estimate for maintenance for my a/c unit. As of right now, I do not have it serviced regularly but would like to if it is not too expensive.
  • Project Location: Dallas, NC
    2 items. At the moment, my air is not functioning very well - may be low on freon and needing a recharge, at least it feels that way. Also, I'd like to get an estimate on a new heat pump split system. My current system is 20+ years old so it's way past time. Probably won't need new duct work, but it's possible they would need to be sealed up some. Thanks.
