Frequently Asked Questions

What's the most common HVAC issue you see in Saint Louis homes, and how do you address it?

We frequently find that clogged air filters and smart thermostat connectivity issues are the most common problems for Saint Louis residents. These simple issues can significantly reduce system efficiency and comfort. During a maintenance visit, we don't just replace the filter; we show homeowners how to check it themselves and recommend a schedule based on local pollen and dust levels. For smart thermostat problems, we troubleshoot connectivity and programming to ensure your system runs smoothly with the changing Missouri seasons, often preventing unnecessary service calls.

Do you handle both plumbing and electrical work on the same job, like during a bathroom renovation?

Yes, absolutely. As a full-service mechanical contractor, we are uniquely positioned to manage multi-trade projects efficiently. For a bathtub or shower installation, our licensed plumbers handle the water lines and drain, while our electricians manage any new light fixture, outlet, or fan wiring. This coordinated approach under one company saves you time, reduces scheduling headaches, and ensures all work meets local Saint Louis building codes. It’s part of our family-owned commitment to providing complete, reliable solutions for your home.

I need a new circuit breaker installed. Is this something you can typically do in one visit?

In most cases, our licensed electricians can complete a standard circuit breaker installation or replacement in a single visit. We start with a thorough inspection of your electrical panel to assess its condition and capacity. Our team arrives prepared with the necessary parts and equipment to perform the work safely and to code. We prioritize clear communication, explaining what we're doing and testing the new breaker before we leave. For Saint Louis homeowners, this means a straightforward solution to power issues or preparing for new appliances.
