Best HVAC Installation Or Replacement in Chesapeake VA

Non responsive and unreliable   If I could give no stars I would.  Bell Cow installed a new Trane system for our upstairs in our dual zone home in October 2019. They told us our other system installed by a competitor  wasn't the right one to do the job. Had problems/failure at the height of summer. Had to contact them five times to get a repairman out. Finally  repaired it but wanted to charge us during the first year after installation! Then the humidity in our home went through the roof. Took several calls and when they finally came out they said it wasn't their unit contributing to the problem. Eventually called another company to install a dehumidifier in our crawl space. Now the same unit which is only 14 months from installation failed to heat! An emergency call to their answering machine at 8:30 in the morning yesterday has gone unanswered. The customer service of this company is terrible.
