Why Homeowners Choose LMH Services
15+ Years of Experience in Every Trade
LMH Services has been serving Southeast Texas since our founding, bringing deep expertise across HVAC installation, repair, and maintenance, plus electrical rewiring, upgrades, and new installations. We’ve seen every type of system failure and know the diagnostics that separate a quick fix from a lasting solution.
Authorized Dealer, Certified Installer
We’re an Armstrong Air Pro Team dealer and a Generac and Champion authorized dealer, meaning we have direct access to factory support, warranty programs, and the latest equipment training. When you choose us, you’re choosing a contractor who stands behind the brands and backs their work with real manufacturer relationships.
Transparent Pricing and No Surprises
We give you a clear estimate before we start work and explain what we’re doing and why. No hidden fees, no upsells you don’t need. If a diagnosis changes what we recommend, we call you first.
Local Team, Local Accountability
Our office and technicians are based right here in Deer Park. You call a local number, speak to someone who knows the area, and get scheduled with someone who will show up. We’re invested in our community because we live in it—and we’re proud members of the Deer Park Chamber of Commerce, the Mont Belvieu Area Chamber of Commerce, and the Pasadena Chamber of Commerce.
Licensed, Trained, and Ready for Any Job
Every technician on our team is trained in current code, manufacturer standards, and the latest diagnostic tools. Whether it’s a routine maintenance call or a complex system replacement, we bring the right certifications and knowledge to every appointment.
Same-Day and Emergency Service Available
We know that a broken AC in July or a no-heat emergency in January can’t wait. We offer rapid response scheduling and emergency service to get your home back to comfort fast.

Our Expertise Across Trades
HVAC — Heating, Cooling, and Air Quality
We install, repair, and maintain central air conditioning systems, heat pumps (ducted and mini-split), furnaces, package units, and whole-home indoor air quality solutions. Our technicians are trained on the latest equipment from Armstrong and other leading manufacturers, and we diagnose problems using pressure testing, electrical measurement, and refrigerant analysis — not guesswork.
Electrical — Wiring, Upgrades, and Smart Home Readiness
Our licensed electricians handle everything from basic outlet and switch installation to complete home rewiring, panel upgrades, and specialty circuits for new appliances. We also install EV chargers for homeowners transitioning to electric vehicles, add dedicated circuits for high-power tools or equipment, and troubleshoot electrical safety issues like flickering lights or tripped breakers.
Generators — Installation, Repair, and Maintenance
Whole-home backup generators ensure your family stays comfortable and safe during power outages. We install permanently mounted generators sized to your home's needs, connect them to your existing gas line or LP tank, and set up automatic transfer switches so they start instantly if the power goes down.
Mobile & Modular Home Specialists
Many homes in our service areas are mobile or modular, and they have unique HVAC and electrical requirements. We understand the compact layouts, the different ductwork configurations, and the specific code rules for manufactured homes.
Our Commitment to You
We measure our success by your comfort and your trust. That means honest diagnosis, quality work, respect for your home, and ongoing support after every job is complete.
Flexible Financing Options
HVAC and electrical projects can be a significant investment. LMH Services partners with Wisetack to bring you flexible financing that makes it easy to move forward — without the financial stress.
