"If I can give this plumbing company zero stars I would. I had a slab leak, and this company came out for leak detection. I was told that I have two leaks and they cut two lines. They were charging almost 65000 for rerouting two lines. My insurance company also brought their own plumbers and did their leak detection and they found only one leak. The adjuster called RT Olson a fraud company and he almost declined my claim. The insurance refused to fix the two cut lines. They only covered one line and I had to pay for the other line out of pocket. I asked RT Olson to fix the other line that he cut and was not leaking but he refuse to take responsibility. Then he send me an invoice for the leak detection and threatens me to take it to collection and add extra fees. This company is a fraud."

"My husband and I are in our 70’s. All of the upgrades/construction in our house in over 26 years was done by my career-construction husband. But recently he hurt his back. We needed our guest bath prefab bathtub/shower removed and replaced with a NICE prefab WALK-IN shower handicapped out. Our 95-year old mom was coming for a 2-week visit. We only had 3 weeks notice. Ani Kevorkian, owner of LGC Construction came to our house 1 day after I called. She listened, REALLY listened to what we wanted and understood the time constraint. She gave us a quote within hours and started the job within days. Her two gentlemen who came out were just awesome and cleaned everything up each day. Then Ani surprised us with “barn-door” glass shower doors that we didn’t even know we were getting. The shower is just beautiful! This company is exceptional. I have and will continue to tell our neighbors, people at our church, friends, etc. about LGC Construction! You can TRUST THEM!!!!"

Install Boiler questions, answered by experts

Since your boiler keeps you warm and provides hot water to your home, you’re likely to notice issues with heating in your living space right away. The most obvious sign that your boiler is breaking is not getting any heat or hot water. You might also hear some odd sounds coming from your boiler during operation, the flame in your gas boiler is not blue, the pressure is inconsistent, or your boiler is using more energy than it should. If you notice any of these signs, be sure to call a pro right away.

The main difference between an outdoor wood furnace versus an outdoor wood boiler is what each appliance is heating. An outdoor wood furnace burns wood to create heat, which warms the air and moves it through the ducts in your home. An outdoor wood boiler uses the heat from burning wood to warm water, which goes through pipes to radiators in the home.

Boiler installations and replacements cost between $3,600 to $8,400. Expect to pay around $5,900 on average for a new boiler, including installation. Adding new radiators or heaters to the boiler may include separate costs if you are also upgrading those components, so the final price may be higher. To decrease costs, you can look for local energy rebates for using a boiler and wait until installers are offering discounts for a first-time installation.

To figure out if your boiler is worth repairing or if you need to replace your boiler, first figure out how old the unit is. Boilers last 15 to 20 years, so if your unit is 15 years old or older, it may be better to replace the entire thing depending on the severity of the problems. If it’s not quite that old, then it’s probably worth repairing. Another thing to consider is whether your warranty covers any of the repair costs. If so, it may be worthwhile to repair your boiler to keep it running.

No, professional installation ensures proper venting, safety, and efficiency.
