Summit Air Brings Comfort to Gregg County Homes

Summit Air Conditioning & Heating has been serving Gregg County families since 1998. Our family-owned company knows what East Texas homeowners need. We deliver 5-star service within 48 hours because we understand how quickly comfort can disappear. When your system fails, you need someone who shows up ready to fix it right. That’s exactly what we do.

Stop Sweating Through Texas Summers

East Texas heat isn’t just uncomfortable: it’s dangerous. When your AC stops working in July, temperatures inside your home can climb above 90 degrees in hours. Your family deserves better. Our cooling solutions include AC repair, AC installation, AC maintenance, and mini splits. We also offer attic blown-in insulation to keep your home comfortable all year. Summit Air gets your system running fast so you can stop worrying about the heat.

Stay Warm When Winter Hits

Cold Texas winters catch people off guard. One day it’s 70 degrees, the next it’s freezing. When your furnace quits on you, it’s more than an inconvenience: it puts your family at risk. Our heating services include furnace installation, furnace repair, furnace tune-up, and furnace maintenance. We make sure your home stays warm no matter what the weather does.

Heat Pumps That Work Year-Round

Looking for one system that handles both heating and cooling? Heat pumps give you comfort in every season. They’re energy-efficient and perfect for East Texas weather. We handle heat pump installation, heat pump repair, and heat pump maintenance. Our technicians know these systems inside and out. We’ll help you decide if a heat pump fits your home’s needs.

Breathe Cleaner Air at Home

Dust, pollen, and allergens build up in your home faster than you think. Poor air quality makes allergies worse and spreads sickness. Our IAQ services include duct replacement, duct repair, and smart thermostats. Clean ducts mean cleaner air. Smart thermostats help you control your comfort and save money. We address the problems you can’t see but definitely feel.

Commercial HVAC for Your Business

Your business can’t afford downtime. When your commercial HVAC system fails, customers notice. Employees complain. Sales suffer. We provide commercial AC and heating services that keep your business running smoothly. Our team understands the unique needs of commercial buildings. We work fast to minimize disruptions to your operations.

New Construction HVAC Done Right

Building a new home or commercial property? Your HVAC system needs to be sized and installed correctly from day one. Poor planning leads to hot spots, cold rooms, and high energy bills. Our new construction services ensure your system fits your building perfectly. We work with builders and homeowners to design comfort into every room.

Gregg County Heat Demands Reliable HVAC

Summer in Gregg County means temperatures above 95 degrees for weeks at a time. Your AC works overtime just to keep up. Without proper maintenance, systems break down when you need them most. Winter brings unpredictable cold snaps that stress heating equipment. Summit Air understands these local challenges. Our maintenance plans keep your system ready for whatever East Texas weather throws at it.

We Serve Communities Throughout Gregg County

Summit Air brings comfort to families across Gregg County. We know the roads, neighborhoods, and unique needs of each community we serve.

East Texas Weather Tests Every HVAC System

Gregg County’s climate is tough on heating and cooling equipment. Summer humidity makes your AC work harder to remove moisture from the air. High temperatures stress compressors and fans. Winter temperature swings force your furnace to cycle on and off constantly. This wear and tear shortens equipment life if you don’t maintain it properly. Summit Air’s maintenance programs catch small problems before they become expensive repairs. We help your system run efficiently no matter what the thermometer says.

Protect Your Investment With Maintenance Plans

Your HVAC system is one of your home’s biggest investments. Without regular maintenance, it won’t last as long as it should. Our Silver Membership costs just $16 monthly and includes two tune-ups per year, 48-hour priority service, and 10% off repairs. Want even better protection? Our Platinum Membership eliminates diagnostic fees and gives you 24-hour priority service. Both plans help you avoid surprise breakdowns and expensive emergency repairs.
