"Great experience Justin, Nate & Timothy were awesome. Very knowledgeable, professional & curious. Aside from the cleanliness they delivered an experience. I highly recommend HL bowman if you want rapid service on your HVAC. Pricing was reasonable in my opinion & financing is an option. Keep in mind when seeking quotes for your HVAC repair/ new install you must consider performance over equipment, that is if your want a good system that will have a good run/life span."

"DEFINITELY RECOMMEND! Joe and Denise are very nice and easy to talk to. They listen to what you need and made sure you understand the plan before they do anything. We asked for extra work and are very accommodating. With regards to work itself, they took their time to do it right. With us, we had a last minute change of septic tank size and Joe was so nice to accomodate us. They did an excellent job with our septic system and will definitely recommend them. We also feel like we gain a friend!"

"The technician called on a Sunday night to get the details; see pictures and scheduled the appointment for the next morning. The young man, Samba and another partner arrived, assessed what needed to be done, took out the damaged tank, and brought in a new tank. They worked diligently and professionally."

"Considering the issue at hand; I had a good experience. I called and spoke with Ken the owner.  He asked me a few questions like if I knew the size of the the current hot water heater; make etc. which I was able to provide.
He heard in my voice the panic and re-assured me that it was not as bad as it appears; so he was comforting to speak with.
I was given a time frame of 2 hours when the workers would arrive with the new hot water heater which was precise.
The mechanic and helper removed the broker hot water heater and replaced with a new one.  Clean up was excellent.

Septic Tanks questions, answered by experts

A leaking well pipe is quite different from if the well itself is leaking. To seal a leaking well, pour a cement mixture or bentonite into the space between the well casing and the borehole wall. The heavier cement collects at the bottom to form a solid seal, pushing lighter materials like mud and fluids up toward the surface. Professional well installation companies have the equipment to do this properly. 

There are a few signs that you might notice if your drain field is bad. For starters, if you see standing water or soggy grass above your drain field, it could mean that it isn’t working correctly. Or, if your yard smells like sewage, it could also indicate that there’s a problem with your drain field. Repairing a drain field costs an average of $2,000 to $15,000.

If your well pump is running continuously (meaning without turning off or stopping), it's a sign that your well pump is starting to break down. The length of time your well pump should cycle is dependent on many factors, like the tank size, pressure setting, and even the amount of water in your well. Generally, your well pump should cycle, or go from running to not running every few minutes.

Yes, septic tank companies must be licensed in most states and municipalities to perform services like installation, alteration, repair, and pumping. Since laws vary by location, it's crucial to check local requirements.

Hiring an unlicensed professional can lead to poor work, code violations, and significant fines. Always verify that your chosen company is properly licensed and fully insured to avoid liability. You can use tools like Angi’s contractor licensing search to check a pro's credentials.

It's also helpful to understand the difference between licensing and certification. A license is a legal requirement to operate, while certifications are voluntary. Credentials like the “Angi Approved” badge indicate that a business meets extra standards, such as passing a background check and maintaining a high rating.

Ideally, you should conduct a mechanical inspection and a bacterial or well water inspection yearly. While you might be able to push it off to every other year, it’s best to have peace of mind, especially when it comes to something that you use so frequently. 

If you experience repeated gastrointestinal illness in the household, it's important to test the well water more regularly for quality and cleanliness to check for bacteria.
