"I’ve been a loyal Snell customer for years, but this recent experience was deeply disappointing. After our AC failed in August, Snell diagnosed a leaking evaporator coil. We chose to replace the system through them, and the salesperson took time to evaluate the setup in advance. However, on installation day, the crew arrived without the correct ductwork and had to make adjustments on the fly. Unfortunately, the adjustments were poorly executed: • The Aprilaire humidifier was mounted on sloped ductwork rather than a level surface, contrary to manufacturer specifications. • The hole for the humidifier was cut inaccurately. • The drain line was left kinked in multiple places. Aprilaire support later confirmed the humidifier was not installed correctly and warned this could lead to water backing up into the system — a concern I had raised with the installers before they left. Despite multiple follow-up attempts, I received no meaningful response. I was told my concerns would be escalated, but no one followed through. This was a major investment, and I now feel I need to bring in another HVAC team to correct issues that should have been resolved from the start. I’ve recommended Snell in the past, but I can’t in good faith do so now after this experience."

"The contractor sent to my house was NOT a licensed electrician. I was told a free quote was 39.99, that turned to 59.99 when I got the estimate and it was waaaaaay over priced and then wanted me to pay a fee to get a warranty for their work! I would have expected a warranty on his work should have been given to me! I needed the job done right away, he was pleasant and courteous but never again with this company."

All Renovations was started by a local graduate of George Washington University. We are fully licensed in all trade work including building, electrical and plumbing . We have always put our customers first in delivering what we promise without any gimmicks. The reputation of our company is proven through our satisfactory track record including winning the highly coveted Angie’s List Super Service Award and being selected as a Best Pick Report contractor on numerous occasions. The staff at our company values your time with prompt on site visits, quick turnaround in providing cost estimates, and a responsive attitude until job completion. We can assure you that our pricing and written warranty provides value in your investment when compared with other professionally licensed contractors. Due to our staffing requirements we are only able to take on jobs $10k or higher.

"I am giving All Renovations 5 stars for the basement renovation in large part because of Adrian’s excellent craftsmanship and attention to detail. Our job was pretty extensive. It included moving support columns, demo and rebuild exterior stairway, adding a full bath, extending the finished/framed portion of the basement, moving the circuit-breaker panel, and re-doing our half-bath. The job took 6 months, which was about twice as long as we expected. Omar was always very responsive and provided good feedback. Adrian is very good at explaining things and soliciting your input when options/alternatives exist. He definitely does not take short-cuts if quality would suffer. He is also very considerate/careful inside your home and cleans-up after himself. Our $102k project ballooned to $125k, mostly due to nice to have add-ons and unforeseen issues. But there were several items I feel should have been caught at the contract onset. E.g. the need for a floor drain ($900), considering that we were getting rid of the utility sink basin. There was also an extra $4k to replace the drywall in the half bath since the existing paint was too textured (sponge) to paint over. But we were very pleased with the outcome and would definitely recommend All Renovations."

Install Boiler questions, answered by experts

If you want a new boiler that’s going to help lower your fuel bills, you should buy one that has a high energy-efficiency rating. For example, a boiler that is rated “A” uses at least 90% of the energy created by the boiler. And in order to enjoy the best performance, it’s important to have it installed properly by a highly-rated tech.

The radiators closest in proximity to the boiler heating system will heat up first. Radiators in rooms farther away from the boiler will take longer to heat up and may be the coolest rooms in the house. The radiator unit itself should heat up evenly; otherwise, there may be trapped air inside it.

Once you install your boiler, you can expect it to last for at least 10 to 15 years. Maximize the lifespan of your boiler by choosing a quality boiler, installing it properly, and having it professionally maintained each year. In the event that your boiler does need repair, address any issues immediately.

Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.

Costs range from $3,000 to $7,500, depending on system size and efficiency.
