our reviews

“I will always use West Mechanical for all my electrical needs. Tony has always impressed me with his work and professionalism. Told me if I had any concerns or questions to give the office or him a call, about 10:30pm last night I get home from work and noticed I lost power to my kitchen and dining outlets and it smelled like something was burning so I called Tony and my apologies woke him up and explained to him what I noticed, he was willing to come to my house late night/after hours to attend my concerns. He talked me through what to check and I noticed a chewed up heater cord that I forgot to un-plug it from the outlet which was the burning smell I notice and hit the reset button on my outlet and “MAGIC” everything is working. I want to thank Tony for his Professionalism, Dedication and going above and beyond for us customers.”

Why Schedule Air Conditioning Maintenance?

Taking care of your heating, ventilation, and air conditioning (HVAC) equipment keeps it at top-rate efficiency. It starts with changing your HVAC air filter at least every 90 days.
