our reviews

“Because of an electrical installation error committed by another HVAC company, our heat pump ran continuously, constantly overheating the master bedroom, sometimes by as much as 15 degrees. When the other company was not able to correct the problem after several attempts, we called West Mechanical for another opinion. Thanks to a team approach involving Tiffany, Brent, Aaron, Kyle and Tony, a complicated problem was identified and completely corrected. Their service was prompt and professional. For the first time in months, our system is operating perfectly. We highly recommend West Mechanical.”

“Honestly, not impressed. Technician was definitely not helpful. Invoice to replace a $39.00 part was over $850.00 and extremely vague. Service department could not justify the excessive cost. Taking my business elsewhere.”

“I was having some issues with my heat pump. Instead of contacting the company first, I left a poor review. I got a call the next day and two guys came by immediately to resolve the issue. I figured these problems were problems that I would have to live with after install. Great customer service. Would recommend. These folks care about what they are doing. I was honestly pretty surprised on how fast they came to help me out.”
