"The service adviser came out and gave us a price. We got three estimates and they were in the middle but were also providing us with more options. The install crew showed up on time and were very polite while on site. They called a few days later to check in and see how we were doing. It was a very simple process. Would use them again in the future,"

"We first used Cottrell Fall 2017 for a hot water heater. Josh came out on a service call one night to assess our issue and recommended a replacement. I love that they have 24/7 hours with no extra charges. A crew came the following afternoon to replace the tank and installed new valves. We called them again when I noticed the signs of a potential slab leak earlier this month. They wanted another company to come out to detect the origination of the leak and then they came out afterwards. The day of the appointment to do the repairs, the appointment before me ran late so they were late getting to me and still stayed to finish the job until about 7:00 PM which I appreciated. I am pretty obsessive about my house being clean so I’ve appreciated their willingness to wear shoe covers and how they clean up after themselves. I have bad allergies so when they had to do the slab leak repair and Brett mentioned it would get dusty so he was putting up some plastic and I said I was concerned about dust going all over, he made a little fortress of plastic to work under to contain the dust in one small area. Of course, not even a plastic fortress can rival all that flying dust but I give him an A for effort :-) They replaced a hot and cold pipe that each had holes in the same area for $2,400. I can’t remember the name of the other tech but he was friendly as well. We noticed our water pressure in our kitchen decreased significantly after this repair and Brett came back again to check it out and cleaned out the hot line in the kitchen where some sediment was causing the low pressure. He also installed a new pressure reducer valve to boost the pressure in the house that has been low. Brett seems to go above and beyond and Cottrell has stood behind their work which has gained my trust in them. I will continue to call on them when plumbing issues arise (though I REALLY hope that won’t be for a while!)"

"Scheduling the work for a new dryer vent was not only easy and prompt, but the young lady who scheduled was more than helpful. The company offered a coupon on Angie's List which I had not purchased. After I mentioned finding the great reviews on Angie's List, she told me I would save by purchasing the coupon, which we did. Wayne and Robert arrived on time and proceeded to install the new vent after explaining what they would do. They reconnected our dryer to the new vents, replaced it and tried it out. Finally, they replaced a door that had been taken down by the new washer and dryer installers when they were done. This is one of the most professional and dependable companies we have had in our home, and we will use them again if needed for duct work."

"After talking with several plumbers, I decided to use Southeast Plumbing and Gas. Brian answered all of my questions and quoted me a very competitive price. Brian installed a new dishwasher, put in a new tankless water heater (plus ran new electrical for the unit) and some other smaller fixes. He was professional, courteous, and did the work for what he quoted. He also tackled some additional plumbing issues that cropped up while he was doing everything else. He was at our house for over 12 hrs fixing everything and making sure everything was working properly before he left. I would definitely recommend SE Plumbing and Gas and would use them again."

"The contractor performed an outstanding installation. The first visit, he assessed the work to perform, then walk me through the process he would perform. He offered various units to accommodate my requirement before I decided on the best option. On the day of the installation, he arrived on time, took the necessary safety precautions, did the installation and then walk me through the process of what he performed and showed me the operations. His quality of work (A+) and the cost (A+) met our expectations."

Install Boiler questions, answered by experts

On average, you’ll need about two gallons of oil per day to heat your house when it’s 50 degrees Fahrenheit outside. Most oil tank capacity is about 275 gallons, and heating your house with two gallons of oil per day will last about four and a half months. This consumption will vary depending on the climate and average temperature in your location. For example, if the winters are longer and colder where you live, you’ll probably need to refill your oil tank at least once to get through the winter.

The cost to install a steam boiler varies depending on the type, fuel used, and your house size. The average cost to install a boiler is $5,900. You could spend $2,000 for a basic electrical steam boiler or up to $9,000 for a high-efficiency oil-burning steam boiler. Boiler installation is a job that’s best left for professionals to complete, and, in some states, only licensed installers can legally complete the job.

The average cost to replace or install a new HVAC system is around $7,500. However, the price can range from $5,000 to $12,500, depending on factors like the size of your home, the type and brand of the unit, and your specific heating and cooling needs. If you only need to replace certain components, the cost will be lower; for example, a new AC unit can cost between $2,200 and $5,500, while a new furnace costs $3,200 to $6,000. If additional work like new ductwork is required, the total cost could be as high as $22,000. It's best to contact a local HVAC company for an accurate quote.

Depending on the size of your home and system, as well as any upgrades or add-ons you choose, it may take between three and five days to completely replace an existing HVAC system from start to finish. Your contractor should be able to give you an estimate before they begin the actual replacement.

The best way to compare HVAC quotes is getting a few detailed quotes from local companies with good reputations. Then, go over the quotes line by line. Protect yourself by insisting on in-person estimates that include equipment manufacturer names, model numbers, SEER ratings, amounts and numbers of materials, details of warranties on equipment and labor, and other specifics. 

Knowing the exact equipment and materials is the only way that you can fairly compare quotes. Quotes that are much lower than others can be a sign that the company isn’t providing the best quality service or materials.
