Adding a new gas appliance often requires a professionally installed gas line.

Older or severely damaged gas lines may need to be replaced to maintain the safety and reliability of your home’s gas system. We replace worn or deteriorated piping using quality materials designed for long-term performance.

Gas Line Inspections

If you’re installing a new appliance, purchasing a home, or suspect an issue with your gas system, a professional inspection can provide peace of mind. We thoroughly inspect gas lines, fittings, and connections to identify potential concerns and recommend any necessary repairs before they become larger problems.

Signs You Need Professional Gas Line Service

Gas line problems aren’t always obvious, but they should never be ignored. Recognizing the warning signs early can help protect your home, prevent more extensive damage, and reduce potential safety risks. If you suspect an issue with your gas system, it’s important to stop using gas appliances and have the problem evaluated by a licensed plumbing professional as soon as possible.

A strong sulfur or rotten egg odor is one of the most common signs of a gas leak and should always be treated as a plumbing emergency. You may also notice a hissing sound near a gas line, dead or discolored vegetation above an underground gas line, pilot lights that repeatedly go out, or gas appliances that no longer operate as expected. In some cases, an unexplained increase in your gas bill can indicate a hidden leak. If you notice any of these warning signs, leave the area immediately, contact your gas utility if you suspect a leak, and once the area has been declared safe, trust the experienced plumbers at Semper Fi Heating & Cooling to inspect your gas line and perform the necessary repairs.

Alex you are so awesome!

The tech that came out yesterday evening was absolutely amazing! He was knowledgeable, respectful, professional, and funny! Instead of saying hey this is what's wrong with your unit and you need this, this, and this, he explained how the AC was working and what went wrong. The previous company (1 hour air 🤮) that we got our gigantic $16,000 air conditioner through about 4 years ago, sold us the wrong unit! They sold us a roof unit for a house that has all the ducts under the damn house! So after spending money with Semper Fi and having them come clean and seal the ducts as well as replace that blower motor in the 1 hour air unit....Alex came out because we couldn't get the unit to shut off. Well long story short the motherboard got fried in the spot that turns the blower off and it was stuck on! Soooo back to Alex, he explained everything and as the second Semper Fi tech to come out to our house - he lasted through all my ridiculous questions and sarcasm! Alex is truly a wonderful guy, he loves what he does and you can really tell that he cares. We had a hiccup in the process of payment and he quickly solved that (also shout out to the guy that also helped me through that process over the phone). Alex stayed through the slightly stressful conversation I had with my mom trying to decide how we could afford a new air conditioner because let's be real spending $16,000 and still owing on the unit after only four years of owning it and then spending even more money to get a new unit is kind of ridiculous! I am very glad that we had Alex come out to diagnose the issue that we were having. He knew exactly what was wrong (very quickly I might add) and he gave us different ways on how it could be fixed. Of course the easy way would be putting a Band-Aid over it but that wasn't what I wanted to do! When I say this company truly is amazing I am not over exaggerating, I feel like even though it is very costly to buy a new air conditioner especially nowadays, Semper Fi made it a little bit easier and I am in love with the fact that all of our questions and then some were answered and explained. I really can't say more about this company besides they hire very good people and they do a really good job!
Please buy Alex a good lunch 😂 or give him something special! 😋 I know he works hard, along with all the guys I have interacted with from this company!
Thank you so much!

We had our AC quoted and they were able to install next day. I followed up with it not quite cooling, and they came right away to adjust the fan speed to get more air flowing. Semper Fi is very quick in response, which is important to me.
