"As a small business owner, I strongly caution others against this HVAC/R company. In over 10 years, they?ve been the least trustworthy and poorest performing contractor I?ve worked with. We experienced repeated service issues, a 25% rate hike without notice, ignored emails, and unreturned quote requests. Worse, we were billed for work that wasn?t done?confirmed twice, including by a third-party inspection with photos. Even when confronted, they deflected and delayed for months. We had to hire another company. They also mis-sized a walk-in freezer due to bad measurements and blamed their supplier. When shown proof it was undersized, they argued with no solution. They later mismeasured again on a replacement bid. Their attitude throughout was defensive, unprofessional, and dismissive. If something goes wrong?and it likely will?they will not stand behind their work. Save yourself the frustration and look elsewhere."

Drain Pipe Installation questions, answered by experts

The signs of a bad mixing valve in a shower include water that’s scalding hot or freezing cold, a leak in your shower, a lack of hot water, and low water pressure. If you suspect there’s a problem with the mixing valve, call a pro to inspect your shower and replace the valve if necessary.

Due to the high temperature, using stainless steel vent pipes for your tankless water heater’s exhaust vent is best. Also, it is safe to use a flexible vent duct as the exhaust fan. If installing the exhaust fan yourself, make sure you are using heat-resistant silicon to connect the exhaust vent and the duct on your water heater.

Replacing a toilet costs between $275 and $480 in most cases, and the average cost sits around $375. This includes removing the old toilet and installing the new toilet. Your price could be significantly higher if you invest in a high-quality brand, need the replacement done on an emergency basis, or replace your toilet as a part of a larger bathroom remodel that demands additional work.

No, fixing or patching a hole in a gas line may not seal it completely. A patch should be a temporary solution because the damaged area will be weaker than the rest of the pipe, increasing the likelihood of future leaks. Therefore, if a gas line incurs damage, call a licensed plumber and have it replaced right away.

Technically, you can put an elongated toilet seat on a round toilet, but it’s not a good idea. Elongated toilet seats are a few inches longer than round toilets, so they will hang over the front edge of your toilet, which isn’t appealing. Additionally, an unsupported toilet seat or portion of a toilet seat is more likely to crack and shift, which could result in injury to whoever uses the toilet. Always match your toilet seat style to your toilet, or replace the toilet entirely if you’re looking to switch styles.
