Granbury Generator Installation 

Built for Lake Homes, Ranches, and Everything In Between

Granbury's mix of lakefront properties, working ranches, and homes spread across unincorporated Hood County means no two power setups look the same. A cabin on Lake Granbury might rely on a well pump and a septic system with no backup at all. A ranch property outside the city limits may sit on propane rather than natural gas, with the nearest utility pole a long way from the house. And plenty of homes here are second properties, sitting empty during the week with nobody around to notice when the power goes out. 

At Airmasters AC, Heat, Plumbing & Electrical, we've installed standby generators across all of these property types since 1985. We don't treat a lake house the same way we'd treat a subdivision home because they're not the same job.

Choosing the Right Generator Fuel for Your Property

In much of Hood County, natural gas service simply isn't available, which means a standby generator has to run on propane instead. 
That changes the planning process in a few important ways:
  • Tank sizing matters more. A propane-fed generator draws down a finite fuel supply, so we calculate expected run time during an extended outage and size your tank accordingly — not just the generator itself.
  • Refill logistics need a plan. If your property is on a long private drive or a road that's hard for a delivery truck to access, that needs to factor into tank placement and monitoring.
  • Above-ground vs. buried tanks affect placement options. We help you weigh the trade-offs based on your yard, your view, and any HOA or lakefront community guidelines that may apply.
For properties that do have natural gas access — more common closer to town — we handle that integration directly, coordinating with your supply line the same way we would for a standby system anywhere else.

Backup Power for Well and Septic Systems

A lot of Granbury homes, especially those outside the city core, rely on a private well rather than municipal water. If your well pump isn't included in your generator's load calculation, you'll have lights and outlets during an outage but no running water. We factor well pumps, and in some cases septic lift stations, into our sizing conversation up front so you're not caught off guard mid-outage.

Keeping Vacant and Seasonal Properties Protected

If your Granbury property is a weekend lake house or a home you're not in year-round, an outage can go unnoticed for days — long enough for a well pump to sit idle, a sump pump to fail, or food in a freezer to spoil. A standby generator solves the basic problem by starting automatically whether anyone's home or not, and we can also talk through remote monitoring add-ons that alert you by phone if your generator starts running or your fuel level drops, so you're not finding out about a problem only when you pull back into the driveway.

Our Installation Process

  • Property and Load Assessment: We walk your property, factoring in well pumps, septic equipment, and fuel type availability, to determine the right generator size.
  • Fuel Source Planning: We size and place either a propane tank or natural gas connection based on what's actually available at your location.
  • Pad and Placement: We set the unit on a properly prepared concrete base, positioned to meet clearance requirements and any applicable lakefront or community guidelines.
  • Transfer Switch Installation: We wire in the automatic transfer switch that detects an outage and starts your generator without you lifting a finger.
    Permitting and Inspection: We handle the Hood County or applicable municipal permitting and coordinate the final inspection.
  • Full System Test: Before we leave, we run a complete load test so you know the system works, not just that it's installed.

Worried a power outage could leave your Granbury home, lake house, or ranch without the essentials? Choose dependable Granbury generator installation from a team that understands the unique needs of local properties. Contact Airmasters AC, Heat, Plumbing & Electrical today to get started.

    Shannon was an outstanding technician. He explained everything along the way and even when he found something that didn’t suit him he made it right. That is what I call going above and beyond and why we want a relationship with this company. Thank you for the outstanding service. I truly feel I have gained a new friend.

    Mr. Holmes was an excellent professional, and undoubtedly a genuine person. Attention to detail and professionalism characterized by his willingness to be accurate and thorough in his work does not go unrecognized! Request Shannon Holmes if he’s available… Great company and ownership!!

  • Once again, Airmasters to the rescue.
    I had a contractor install two Nest controllers only to find them not working properly. Airmasters came out, diagnosed the issue and fixed the problem. The service tech Hunter also found a potential problem in one of my heating units that could have resulted in a fire. If you need electrical, plumbing or AC help, go to these guys. I can’t recommend them enough.

  • This company is an extra effort company.
    In the past two years we have had a new central air system and have had our old breaker panel replaced by Airmasters. Excellent job by them both times. Everyone we came in contact with was a pleasure to deal with, especially the guys that actually did the work.
    Rocco C.
  • I will continue to use this company over and over again.
    Jacob was AMAZING! I honestly can’t thank him enough for helping us out. He actually had to come out three times to fix another company’s issue and he was so kind and helpful each time.
    Courtney E.
  • I would highly recommend Airmasters to my friends.
    Shannon arrive early and called to ask to go into garage, as I had left door open. I arrived home about 30 minutes, and he introduced him self to me from attic. Replacing the motor took about 2 house. I am completely satisfied and A/C again.
    Suzanne M.
  • Thank you for such a quick and fantastic job!!
    I came home to a warm home on Tuesday evening. I was referred to AirMasters and gave them a call at 5:20. Shannon Holmes was out to my house by 6:30. By 7:45 our AC was fixed!! He was very honest, friendly, and professional! We signed up for them to service our system because of the professionalism that was shown to us.

  • I’m glad they have my back.
    We’ve had two issues since we moved into our new home six months ago. Both times technicians were sent out late in the evening within an hour. They were courteous and quickly diagnosed the problem on a new-to-the-market system. On the occasion it couldn’t be fixed immediately, Derek made sure I had heat until it could be taken care of. They were back the very next day to get it fixed!
    Leigh O.
  • Total professionals. Thanks again!
    Troy Endtricht was my technical and I couldn't be more pleased. He took time to tell me thing about the system I did not realize. He gave me a complete rundown of the system checks he conducted. Airmasters installed this system in my new home and did a super job. Their follow up service is excellent and rapid if desired. I would use them for all your Heating and Air needs. They haven't been in this business for 35 years because they are doing something wrong.

    FAQs About Generator Installation in Granbury

    My property is on propane, not natural gas. Does that change what generator I need?

    It affects tank sizing and placement more than the generator itself. We calculate your expected fuel consumption during an extended outage and size a propane tank to match, since propane is a finite on-site supply rather than a continuous utility line.

    I have a well for water. Do I need to plan for that separately?

    Yes. If your well pump isn't wired into your generator's power plan, you'll have electricity but no water pressure during an outage. We include well and septic equipment in your load calculation so the whole property stays functional, not just the parts connected to the main panel.

    My house sits on a large piece of land. Does that affect where the generator can go?

    Larger rural lots often give you more placement flexibility than a tight subdivision yard, but you still need to meet clearance requirements from windows, doors, and property lines. We assess your specific layout during the site visit.

    My home is a weekend property and sits empty most of the week. Is that a problem for a generator?

    Not for the generator itself — it starts automatically whether you're there or not. We can also add remote monitoring so you get a phone alert if the unit starts running or the fuel level gets low, which is especially useful for a property you're not checking on daily.

    Do I need a permit for a generator in Hood County?

    Yes. Requirements depend on whether your property is inside city limits or in unincorporated Hood County, and the process can differ from what's required in nearby cities. We handle the permit application and coordinate inspection either way.
