Had a zone valve stuck open and got an astronomical estimate from STROGENS. Called Stevens Mechanics and Lee came right out and fixed it for way less than STROGENS estimate. Looks like we have a new company to maintain our heat sources.
First, I want to say we are not related. Lee was extremely responsive. He was coming off a week of sickness and still offered to come that night but I explained we could wait until the next day. He was there right on time, fixed the problem after a lengthy trouble-shooting session and was very reasonable in terms of price. He will be who I call the next time we need work done.
⭐⭐⭐⭐⭐ True 24/7 Emergency Service – Stevens Mechanical I had a late-night heating emergency during extremely cold weather. Stevens Mechanical answered immediately and treated it like a real emergency — not a voicemail or a callback. He gave clear, practical instructions to keep the situation safe until he could arrive, then showed up promptly and handled the issue professionally. Communication was clear, the response was fast, and the service was exactly what you expect when a company says they offer 24/7 HVAC service. What really stood out was the transparency. Once on site, he explained every step of the process as he went, answered questions clearly, and took precautions to ensure he was only fixing or replacing what was absolutely necessary. As soon as he identified the problem, he explained exactly why the part needed to be replaced and what it would take to replace it, so there were no surprises. Reliable, professional, and trustworthy. I would recommend Stevens Mechanical to anyone who needs emergency HVAC service, especially after hours.
Gave me precise instructions over the phone with patience and helped me fix my problem without even showing up.
Lee is a great guy. Saved me last minute with an expansion tank replacement, good pricing and super helpful. Will definitely be calling again the the future when I need any work done.
