My workman said if he hadn't discovered the exposed pipe, I would have had burst water pipes very soon due to the freezing temperatures. Rather than cut the insulation and replace it when done, they just tore it down.

After the expansion tank was added and adjusted on the hot water tank my washer and dryer have to be squeezed back into place, pipes have to be pushed out of the way to make the washer and dryer to fit. I'm going back downstairs to attempt to rectify this situation. I'm not happy that I have to do anything at all. It cost me enough. Would I recommend Heritage Home Service? No is the short answer...

Called Heritage for simple furnace maintenance as is done in the fall. Technician arrived and got…read moreto work. About 30 minutes later he came upstairs and said he had some bad news......my heat exchangers were shot. I'd need to either replace them for about $8,000 or his recommendation would be to get a new system as ours is 10 yrs old. He showed me some pictures of my heat exchangers. I really don't know what they were. The new system would be about $25,000. What he didn't know was my dad owned a heating and cooling business. No one makes a diagnosis like that without even turning the furnace on, except Heritage apparently. You can bet I was calling for second opinions before he was out of my driveway. I had two separate guys tell me my system is FINE. Had my maintenance done by one of them and you can bet I'll be sticking with them!

Something lets go, there's the sound of rushing water, and the whole downstairs fills up with steam. It was so thick I couldn't even see a foot in front of me in the basement as my plumber, Darren Powers, talked me through on the phone how to shut the furnace down, and which valve to turn to get the water to stop. Man! What a mess.... Darren was such a help to me. Though he had been up since early that morning working a job when I reached him at around 7:00 pm, he came over as soon as he could around 9:00 pm and worked on stabilizing things until about 10:30 pm so nothing else would happen. Because it was Saturday, he wasn't able to come back until Monday after gathering all the parts and equipment needed to fix the furnace and burst pipe line. I've known Darren for years, and he's helped me on many occasions. Each time, he came as soon as he could, did great work, and cleaned up the resulting mess after. I've trusted him numerous times to come in to do his work even when I wasn't home. And he's always been more than fair with not only his prices, but also his time. It doesn't get any better than that. Thanks, Darren. You're not only a great vendor, but I'm glad to have you as a friend.

Once again threatened with cops. Offered him $160 in CASH. Told me it was $180. Gave him the cash. He called me a fucking dyke. And then yells it at me. Basically stole my money and then proceeded to insult me. Would not, under any circumstances, suggest connecting with this person. Also threatened me with a law that didn't apply, so must not be the first time he's done something like this to a customer. Steer clear. ADDENDUM: Called the cops on me for harassment. Officer Carter, specifically. Threatened by a fucking dyke who doesn't have his address but he has mine‽ Christ on a cross.
