Derry Plumbing, Heating & Air Conditioning

We didn't have water for the entire weekend. We called 5 different places. A few took our calls to schedule for a later time in the week, but Dave was the only one who called me back and made our situation a priority. I am so happy he did that for us. He made us feel important. They took care of my water issue the very next day first thing in the morning. His crew and his teams customer service was great. They were friendly and explained everything really well. I highly recommend this company.

Unprofessional. They never completed our air conditioning installation and blamed it on our thermostat, which they inspected prior to installation. Our electrician is telling us they should have had an electrician assisting during the install. Air conditioner still not working, and according to Dave at Derry Plumbing and Heating it's now my problem, swore and hung up. Do NOT USE DERRY PLUMBING AND HEATING!!

I called this company to replace a kitchen faucet. They sent over two very young men.. one of which was clearly inexperienced.. but they did get the job done. However, they ended up breaking one of the other pipes under the sink so water leaked everywhere including into my basement. The pipe was completely separated from the bottom of the sink. I called them back on Friday night.. and never got a return call. I called them again on Saturday and the owner basically said the pipes where old and had nothing to do with his work. I just had the entire kitchen redone, including all new PVC pipe 8 years ago. I offered to pay for the repair itself.. if he would waive the 69 dollars service fee you pay just for them showing up. He wouldn't even meet me in the middle on this! He was very rude to me, and basically said he wouldn't come over to fix this if I ""threatened"" him with an honest review of these services. Needless to say we won't be using this company in the future and I recommend you stay clear of them as well.

Agree with another reviewer here who commented about poor customer service by the owner Dave. After the work was done at my unit, I called asking for an explanation of the charges and to question why it was higher than what I was lead to believe initially. Dave goes on the offensive from the get go. ""You have a cheap piece of plastic crap called a faucet and you should be glad we repaired it instead of installing a new one""...these are his actual words. Dave needs to be schooled urgently on customer service for sure. Pity the folks who work for him who have to handle such a condescending and foul mouthed boss everyday.

I used this company in Sept. 2018. My request was to get a hot water heating furnace that hadn't been operated for 5 years checked out and whether it was worthy of firing up. I know it was my mistake of accepting a verbal quote and not requesting anything in writing, but to be fair, he didn't offer a written quote either. All of the pressure relief valves and other coupling on the furnace had burst due to what water had been left in the system when shut off which would have to be replaced before being able to use the furnace again. I told him not to do anything about any leaks in the piping throughout the house, that I would make all those repairs. His verbal quote was $800 and I gave him a key as the house was empty at the time. He said it would likely be an all day affair, a Friday.


Monday, I was there working on other things and his employees showed up. They had replaced all the valves and coupling and told me that they did three repairs on leaks on the first floor baseboard heaters. I told them they weren't suppose to do any of that work. Doing our talk, one employee said they had been there about 4 hours Friday, the other said more like three hours. After about another hour of doing a tune-up, they opened up the viewport and fired it up. They immediately shut it down and after poking around in the furnace with a rod and flashlight, told me that the inside firebox ,wall, whatever had failed and that they would have to disable the furnace before leaving. He called and talked with Dave awhile, then told me it would be around another $800 to replace the firewall. They had never opened the furnace and vacuum or visually inspected the chamber.


The next day, he called my sister, the estate executor, and requested $1500 for the work they had done thus far. When she inquired about the increase, he mentioned the three leaks and that he gets $250 per leak. He quoted a replacement furnace for around $7-8000 with no allowance for work performed so far and that he considered himself to be in the middle as far as his pricing.


We had the furnace replaced by live free for $10,000+. The newer systems don't need all the pressure relief valves and such, so that was all money down the drain. They stayed with us right up to the inspection by the fire department

Telling my story to various fiends and Derry business owners, I kept getting told I should have asked them about him. They would have told me to stay away. I was also told he use to sell used cars, though I can't verify that. If you do deal with this company, make sure you protect yourself with a scope of work contract, and get other quotes.

Called with what seemed to be a bad zone valve. My thermostat would be off and my condo would still be extremely hot. Called Derry plumbing and heating, as recommended by my property management, asked prices, 800 dollars to pur in a valve with just a knob, i asked price to have valve with use of thermostat the only answer i was given was ""drastically more expensive"". I had them replacr the valve this past weekend with the knob. I have had it turned off and temps are still the same as before, extremely warm. Called to see what could be done as i paid 800 to fix it, and i just got the run around for answer. Seems scam like to me.

The crew replaced our water heater today, and brought the connections up to code. No surprises, job was done quickly, and the estimate provided prior to the job was exact and fair. David was very responsive to questions and with scheduling prior to the intallation.

If you want poor customer service, and inappropriate foul language from the owner while discussing services rendered then this is your contractor. We recently had our HVAC system replaced. The wiring on the systems was sub par, and interfering with the placement of the hepa filter . I am an electrical engineer and qualified to recognize such issues. When I questioned the work done the owner was extremely foul with language and non responsive to the issues at hand. This company may give you a low bid, but will deliver sub par work and not stand by their work. Buyer Beware!!

We just experienced a frozen baseboard heating pipe. I called several plumbers and was told the wait would be 5-7 days to get someone out. Called Derry Plumbing and Heating. Very nice girl on the phone took my number and would call right back. She did in about 5 minutes. Told me someone could come out the next day. Technician Sean showed up 1 1/2 hours early. Found the split in the pipe, cut it out, replaced the section of copper pipe then filled and purged the heating system. Everything was done great. Cleaned up after himself. Very very satisfied. Reasonable price considering it was an emergency.
