"No estimate or work was done so I can't comment on any of that. The salesman apparently so hated to wear a mask that he felt the need to be rude and unprofessional. When an emergency occurred during his visit, he got angry and ran – embarrassing himself and his company. To add insult to injury the company leadership felt the need to insult and try to provoke me. Yes, at the same time the salesman arrived we had a pet emergency. Clearly a minor one to some. The death of a baby chick. Sounds like a joke but it isn't. I have limited mobility so I shouted to my wife for help believing my wife's remaining chicks were also in immediate jeopardy. She was in her flower garden so I opened the window and shouted for her by name. She could not hear me. After watching the remaining chicks suffer in pain I again called for her. Panicking now, I shouted a third time as loud as I could for her, again by name. Not knowing the salesman had even arrived. I didn't know why she was delayed. Hearing me, our oldest son left his mom with the salesman and came to my aid. Upon his arrival and after seeing and evaluating the situation, he went for help. I left the room with him. At that point I saw the salesman, for the first time, in our bathroom at the sink with the door wide open. I asked (using please and sir) he allow me into the bathroom. Like a shot he left the bathroom, angrily stomped down the stairs, out the door and sped away. When I saw my wife she was almost in tears. She was very upset and it took her a number of minutes just to calm down. According to her, and my son, the salesman came up to her in the garden not wearing a mask. We had requested he wear one and was assured by the scheduler that he would. When she asked if he would put on a mask he leaned forward into her face and shouted "what!?!" I can't explain how freighted she told me she was. My son told me he was shocked and believed the salesman came so close to her face and over-accentuated his response to demonstrate how much he resented being asked to wear a mask. My son said it was as if the salesman was faking a cough or sneeze into a customer's face as others have done before being thrown out of stores, etc. According to my son, at this point he heard my shouts for help and left his mom with the salesman and ran to help me. According to my wife, the salesman then held a mask to his face and sarcastically said, all right!?, can we do this!? He apparently followed her as she quickly walked away from him and toward the house. When he entered the house right on her heels, he again very sarcastically said, can we just do this now!? As she described it to me, she with up the stairs with him closely behind. When she went to show him the needed work upstairs, he just left her and went to the bathroom - where I saw him for the first time. Any animal dying in my hands touches my heart - that's just me. As a 60+ yr old 100% permanently disabled veteran you can accuse me of being overly sensitive. My wife is a long retired 30+ year RN, nearly my age and is now my full-time care giver. I am house bound without her. Clearly she and I are not a threat to anyone. Immediately, not knowing what happened I called Handyman Connection twice, hoping to reach someone to find out what had happened. I left two message asking for a return call immediately from someone in authority; that I didn't know if I needed to call an ambulance or the police since my wife was unable to tell me what happened. I wanted an explanation and I wanted it immediately. I got a call back alright…. Apparently from one of the owners. He said he had spoken to the salesman already and knew exactly what happened. He sarcastically 'apologized' and that his salesman understood, that my wife and I must just be ‘having a bad day.’ I was livid. When I accused his salesman of being "mean" to my wife the owner's anger exceeded mine by 100%. He made it clear to me his worker had been an employee for many years and had "hundreds" of positive reviews - that it was just me and my wife. When I repeatedly tried to express the results of the salesman's visit -- the owner verbally fought me, clearly not even pretending to consider any other view but his own. I am not a fighter. I have gone to great lengths to avoid conflict, even to the point of accepting, even fainting support when someone misses or needs to change an appointment, etc. This is a weakness that I have been working on for years. I will do anything to avoid making others feel sad, bad or embarrassed. However, the salesman, and now the company owner had insulted my wife. The owner refused to give me an email address so I could more clearly explain what had happened when I calmed down. He said he didn't want to hear any more of it, or from me again. He added that I was obviously a serial complainer and I didn't matter anyway. He ended by hanging up on me."

"We hired this company to replace our HVAC system several years ago. They provided a ten year warranty. When we had problems, we called them and they diagnosed a leak (the same issue we had with the last HVAC). Even though it was within the warranty period, they insisted we had to get an entirely new HVAC and that it wasn't covered. Their customer service was abysmal- repeated sales calls for a new HVAC system by folks who had no idea that we had already had a service visit, but no information on our technician's diagnosis or pricing. Management we finally spoke with were extremely rude and dismissive. We will never use them again."

Install Boiler questions, answered by experts

Most propane boilers last 15 to 20 years with regular maintenance and proper care. The lifespan depends on the quality of the unit, proper installation, and the level of maintenance. Investing in annual service can maximize longevity and efficiency. Routine inspections and timely repairs prevent early breakdown, ensuring your boiler heats your home for years to come.

Coolant and antifreeze are technically not the same thing. The difference between the two is the ratio of water to other chemicals. True antifreeze is mainly made up of either ethylene glycol or propylene glycol, while coolant comprises one part antifreeze and one part water. However, the terms coolant and antifreeze are often used interchangeably, even by pros.

Yes. Boilers need water to run without overheating, also known as dry firing. If you run it without a sufficient volume of water, either because of a burst pipe or a leak, you run the risk of damaging your machine or jeopardizing the safety of your home as a whole. When in doubt, shut off your boiler and repair any plumbing issues before turning it back on. Alternatively, consider installing a low-water cutoff (LWCO) before any issues arise. This gadget will protect your boiler by monitoring water levels and automatically shutting it off if it gets too low. 

No, there isn’t always water in radiators. In a one-pipe system, water is constantly circulating from the boiler to the radiators and back. In a two-pipe system, water travels through two separate channels: one that goes to your radiators and one that returns back to the boiler so it can heat up again.

Each has its pros and cons, but hydronic heaters typically cost less to use than electric heaters, and they’re slightly more efficient than electric options. On the other hand, a hydronic heater usually takes a bit longer to heat up a room than an electric heater. The “better” choice depends on your needs and budget.
