My name is Glenn Cummings, owner of A Royal Flush drain cleaning company serving the upper keys, 305-619-5330. I have over 20 years experience and owned a business by the same name in N.J. for 11 years. I had 5 star ratings in N.J. before moving to Islamorada in April. I pride myself on being prompt, clean, and doing the job right the first time, all at a great price. I am looking forward to doing business in the keys, I've wanted to live here since I was a teenager. Thanks for your business, Glenn

"The first three firms i contacted before using HomeAdvisor were not going to be able to deal with our emergency for a month or more. Glenn from Royal Flush called me from the Angi inquiry and said he be here in an hour or an hour and a half. It was an hour on the dot. He was thoroughly professional, diagnosed and solved the problem, and charged more than $100 less than another bid I received. Bravo Glenn and A Royal Flush!"

"Michael Gomez and Unique Bath are crooks! They sold me this dream and promised to fix the issues presented to them, but have been avoiding me. Check out BBB, they were revoked for all of the complaints, do your due diligence before hiring a contractor, I am warning you!!!! When uncovering the vanity and toilet that was covered in plastic sheeting, it revealed a large chip out of my vessel sink bowl and a large chip out of the top of my toilet tank. While installing the glass contractors dropped the glass while in my brand-new shower and shattered the glass and caused a significant amount of damage to my brand-new shower, that I have not even gotten to use yet. Now I have glass everywhere, blood everywhere and a damaged bathroom! I spoke with one of the owners, Alex and he stated that a new glass panel was being rush ordered for next day installation. I remained calm, as at this time I was worried about the glass contractorsâ hand that had a deep gash. They did attempt to clean up the glass and blood as much as they could, however there was so much left for me to clean and deal with afterwards. After cleaning up as much glass as I could, I notated the damage that was apparent and contacted Erika and did not get a response. The next day I was told the glass was being picked up at 11:30am and I was antsy and rushed home from work to await the delivery and install of the new glass. I waited until 4pm to contact Erika to find out what was going on and was then told that the glass was in fact not ready and that it wouldnâ t be ready until the following Monday or Tuesday. By this time, a month from the start date of the project has elapsed. I then again addressed the damage in the bathroom and was told it was forwarded to the owners and it would be addressed the following week. By now I am feeling that my concerns and are being brushed off as though it does not matter that they have damaged my vanity, toilet, brand new shower, walls, sink and shower faucet. I have also made them aware several times that the shower is leaking and now that they are paid in full, they seem to not care!!! As of today 09/25/23, over a year has passed and these items have not been corrected, although I have been promised on several occasions that they would be! BEWARE!!!"

Install Boiler questions, answered by experts

Most home boilers will need an expansion tank. That’s because these boilers are closed-loop systems, where the water is trapped. An expansion tank is needed when the boiler heats the water and it expands, allowing air to condense in the tank to make room for the water. Other types of boilers don’t use an expansion tank, such as traditional steam boilers, but these aren’t as common. And hot water tanks may be able to use a pressure release valve instead. When in doubt, call in a pro to take a look.

If your boiler is 20 years old, it’s time to get a new one. Although it may seem to be working fine, it’s likely eating up more fuel than it should. Also, compared to a brand-new boiler, one that’s 20 years old is probably not working as well. When you get your new unit, you’ll notice that your home is heating more quickly, and the heat is consistent throughout all the rooms.

While you’ll pay more upfront for a brand-new HVAC unit, you can save money in the long run. Here’s how to save on your new HVAC system:

  • When purchasing a high-efficiency system, your energy bills will be lower in the future.

  • You may be eligible for special offers from your local energy company.

  • Depending on the system, you may be eligible for HVAC rebates and tax credits.

  • Choose to replace your air conditioning unit and furnace simultaneously to save on labor and installation costs. 

Costs depend on issue severity, parts needed, and labor rates.

It takes about five to 10 minutes for heat to reach a radiator, then about one hour until the radiator fully heats up a room. The exact duration depends on the size of the room and how far away the radiator is from the boiler heating system. Heating up an entire house could take up to two hours.
