How We Work: From Your Call to Completion
Whether you’re calling for an emergency repair, scheduling routine maintenance, or planning a major installation, here’s what to expect when you work with LMH Services.
Call 832-800-4564 or submit a service request online and you’ll reach our scheduling team. We ask a few questions about your system, the problem you’re experiencing, and your availability. For urgent repairs, we prioritize same-day or next-day service based on technician availability and the severity of the issue. For planned installations or maintenance, we work with your calendar to find a convenient time.
You’ll receive confirmation with the technician’s name, expected arrival window, and our contact information in case you need to reach us before the appointment. Our technicians call 15–30 minutes before arrival so you’re not left waiting all day.
The technician arrives with a fully stocked service vehicle, diagnostic tools, and access to technical documentation for all major brands. For repair calls, we start with a thorough diagnosis—checking electrical connections, measuring refrigerant levels, testing components, and reviewing your system’s service history if available. For installation consultations, we assess your space, existing infrastructure, and specific comfort needs to recommend the right equipment size and configuration.
We explain what we find in clear terms, show you the problem when possible, and outline your options. If it’s a simple fix, we’ll tell you. If the system is nearing end-of-life and a repair is only a temporary solution, we’ll be upfront about that too. You make the final call on how to proceed.
Once you approve the work, we get started. Repairs are completed on the spot when we have the parts on hand—most common components are already in our trucks. If we need to order a part, we’ll give you a timeline and return as soon as it arrives. For installations, we coordinate permits, schedule the work over one or more days depending on project size, and ensure minimal disruption to your household.
Every installation follows manufacturer specifications and local code requirements. We pull permits when required, coordinate inspections, and handle all the documentation. For HVAC installs, that means properly sizing ductwork, testing airflow balance, charging refrigerant to exact specs, and verifying the system cycles correctly under load. For electrical work, it means clean wire routing, correct breaker sizing, proper grounding, and passing final inspection.
Before we close out any job, we test the system thoroughly. For HVAC repairs, that means running full heating or cooling cycles and verifying temperatures, airflow, and thermostat response. For generator installs, it means simulating a power outage and confirming automatic transfer switch operation. For electrical projects, it means testing all circuits, verifying voltage at outlets, and confirming GFCI protection where required.
Once we’re satisfied the work is complete, we walk you through what we did, show you how to operate any new equipment, and answer any questions. We explain warranty coverage, provide written documentation, and leave you with our contact information for follow-up support.
Your relationship with us doesn’t end when the truck drives away. All repairs and installations come with our workmanship warranty, and manufacturer warranties apply to equipment and parts. If something doesn’t perform as expected, we come back and make it right—no runaround, no excuses.
We also follow up on major installations to check in, answer any questions that came up after you’d had time to use the system, and schedule your first maintenance visit if applicable. For customers enrolled in our maintenance plans, we handle scheduling proactively so you don’t have to remember when your next tune-up is due.

Not Sure If We Service Your Area?
Chances are we can help! We’ve served the southern Houston area for a while, so please call 832-800-4564 or contact us today to see if we come out to your area.
Our technicians arrive with the tools and training to diagnose your problem accurately before proposing solutions. We don’t recommend replacing a system if a repair makes financial sense, and we don’t patch problems temporarily when a long-term fix is needed.
Every HVAC technician on our team carries EPA 608 refrigerant certification and has been factory-trained on the major brands we service. Our electricians hold full Texas state licenses and stay current on NEC code updates.
We install and service equipment from manufacturers we trust—Armstrong, Samsung, Generac, and Champion among them. Our Armstrong Air Pro Team dealer status means we’ve met rigorous standards for training, customer satisfaction, and technical competency.
Before we start any work, we provide a clear estimate that covers labor, parts, and any additional services required to complete the job correctly. If we discover additional issues during a repair, we stop, explain what we found, and get your approval before proceeding.
We’re based in Deer Park and have been serving the greater Houston region for over 15 years. When you call our number, you reach our team directly, not a national call center. Local accountability means we stand behind our work long after the invoice is paid.
