But the boiler started acting up around the same time. Specifically, it wouldn't always come on when the thermostat called for heat. It would begin the startup sequence, but then give up and fall silent after a few seconds. By cycling the boiler and the thermostat I could get it to come on, but clearly something wasn't right. Mark came back out and found that the flame sensor was dirty. This was causing the pilot to fail to light (or not be detected), and thus the boiler was blocked from starting. He fixed that, and also replaced the automatic damper motor, which he observed acting up. Foley has done a couple of small (sub-$1000) jobs at our house before, and always done a terrific job. On this job there was a problem with the price I was charged for the damper motor. I looked up the retail price, and called Dan Foley to discuss. The conversation did not go particularly well. But to Dan's credit, when we spoke a second time, he finally had a good explanation for why the part was so incredibly expensive, and the matter was resolved to everyone's satisfaction.

The two people who came to do the work were punctual and left at a reasonable time (before dinner). We had to have drywall work done in the area they were working in and they were able to reasonably accommodate the person doing the drywall work. The work itself was neat and attractive- the soldering was well-done. They definitely had some old-house challenges to overcome and were patient and persistent. The estimate was among the lowest I received, yet the experience was among the better I've had with contractors. I think they sized the boiler better than anyone else would have. They installed one almost half the size of the one we had. The other contractors all wanted to put in a boiler half again as large. There was some difficulty in getting two of the radiators to work after everything was installed. However, Aspen was able to send someone out immediately the morning after the install. He spent several hours troubleshooting the problem- which had to do with how the piping was originally configured and nothing to do with the new boiler installation- and was able to correct it and get the last 2 radiators on board. The correctly sized boiler and new thermostat have made a huge difference. We're experiencing a much more evenly heated 2 story house.

We hired them to clean our two chimneys and at this time they recommended that we install sterling silver linings in both of our flues due to a fire hazard. Based on the information provided to us by this company, we decided to install a sterling silver tube in our downstairs chimney/flue. The company spent almost 10 hours installing the sterling silver tube on January 13. That evening, our boiler shut off and the radiators turned off. We had no heat. The next day we paid for an emergency visit by a plumber, who told us a carbon monoxide sensor in the boiler was triggered and recommended we contact Priddy Clean Chimney Sweep. It turns out that Priddy Clean Chimney Sweep was completely negligent in recommending the installation of a lining in our flue because they cut off the exhaust pipe of our boiler. As a result, we spent three days without heat in January due to our legitimate fear of carbon monoxide poisoning. When Priddy returned to fix the problem, they ended up hitting some pipe that flooded our basement (our tenants unit). There was about an inch of water in our tenant?s bedroom. They spent all day working on the issue and never found a solution. They just pulled out the silver lining and left. The problem was that our house is 115 years old and at one point was heated by coal, resulting in the boiler venting into the chimney flue. A competent chimney company would have checked to ensure that this was not the case before installing a sterling silver lining that created a serious hazard to our home and health. Even though Priddy Clean Chimney Sweep refunded most of our money, we still felt at a severe disadvantage after spending three days with no heat and paying for a plumber to come out. I would highly recommend not using this company. They created a dangerous situation that resulted in us being in fear for our health, our home, and wasted over 20 hours of our time."},"url":"https://www.angi.com/companylist/us/md/beltsville/priddy-chimney-solutions-reviews-162748.htm"},"position":7},{"@type":"ListItem","item":{"@type":"LocalBusiness","name":"SAINI AIR CONDITIONING","address":{"@type":"PostalAddress","addressRegion":"MD","addressCountry":"US"},"review":{"@type":"Review","author":{"@type":"Person","name":"SHANNON K."},"reviewBody":"They were able to come on short notice (one day) in advance of a cold snap, and were very friendly, prompt, and thorough.

"I have used Grove for many years, and even had them replace on of my failing units. Within the past 18 months, our secondary unit started having problems and Grove came out multiple times to service the unit, explaining that it was losing refrigerant and needed to be replaced. They were always very quick to provide an estimate to replace the unit after charging it. Before replacing the unit we had a different vendor come to give a second opinion, to ensure we were informed and I am so happy that we did. We found that the unit wasn’t only running out of refrigerant, but that it was massively overcharged and that the overpressure safeties had been defeated. I’m not sure if Grove was simply negligent or if they were trying to trick us into paying for a replacement, but I can say that I won’t be using them again. The unit they replaced for us is already dead, and they are quoting us an additional $2k to repair it, putting the total cost for the unit at nearly $10k. All said I have probably paid Grove thousands of dollars and it’s impossible to tell what of that was legitimate and what of it was them running up the bill. I can tell you that at one point they made an emergency visit late at night, spent 15 minutes looking at, and cleaning my compressors, charged me $1000, and then proceeded to text me pictures of them on vacation, presumably enjoying spending the money I had paid them. While I really like Grove, I would suggest you get a second opinion regarding whatever they tell you and that you check your bill very thoroughly."

"I called to get an inspection done on my AC unit and was quoted $90 for the inspection plus $120 an hr for ADDITIONAL hrs. I ASKED when do I know when the “additional hrs start”, He stated that the tech would let me know once the inspection was done and then at that time he would let me know if there was work that needed to be fixed or if there was nothing then the service would end and I would only have to pay the $90. They charged me $210 for the inspection. I called and requested that we both listen to the call (Because all calls are recorded) They played the call, heard what the rep said and then stated they would get back to me. When I finally reached them again (they never called me back), they stated I would not get a refund, then replayed the call cutting out the part when the rep stated clearly that the service was only $90.

FAQs for boiler repair projects in Ridge, MD
The average cost to install a new water heater is around $1,300, but you can expect to pay between $875 and $1,750, depending on the kind of water heater, the size of the unit, and the professional chosen to complete the work. Tankless water heaters can push your price higher, as installation is more complicated, with prices as high as $3,500. The location and accessibility of your water heater will play a role in the project cost, as those sitting in tight spaces like a crawl space will drive up your labor costs.
Yes, most states require plumbers to be licensed, and for good reason. Hiring an unlicensed plumber could lead to poor quality work, costly future expenses, and potential code violations.

Required to have applicable state and local licenses
Maintain an average star rating of 3.0 or better on our network, if they have at least one review

It is very difficult and dangerous to install your own water heater, so we strongly recommend against tackling this as a DIY project. Not only will you need to wire your water heater, but you’ll also need to connect plumbing to the intake and outlet. Sweating copper pipes and connecting wiring properly are skills most DIYers don’t have, and even if you do feel confident you can do it, working with water and electricity always leaves the potential for electrocution. Hiring a local water heater installer is well worth the investment.
The average cost to hire a plumber is around $100 an hour but can vary between $45 and $200 an hour depending on the plumber’s experience and the repair that you need. It’s also important to note that these prices can go up on holidays, and emergency plumber rates average $150 per hour, in addition to a flat-rate trip fee of $100 to $350.
