I tried to reach Jeff over the next few days without success. In the mean time the A/C still was not working. I decided to get a second opinion from Gulfstream Cooling given the strange comments from the Smyth technician. Gulfstream was prompt and professional and contacted me over the weekend. They went out the following Monday and found the following. They had to reattach the expansion valve sensing bulb and to recover the overcharge of the refrigerant put in by Smyth. They also found that there is a problem with the air flow that which effects both capacity and efficiency. When the system was installed the existing supply duct plenum was used and is too small. The other item is that the return duct is also not sized properly and sucking attic air from a few leak spots. A coil cleaning was also needed. I have had a maintenance contract with Smyth for severa

We called PG&E to come out and see what was wrong, but they couldn't come until Monday, so by then we were really getting annoyed with the problem. The PG&E guy diagnosed the problem: it was just dead batteries in the thermostat (we just bought the house and didn't even know there were batteries in the thermostat). However, as part of his routine safety checks, he sprayed the 20 year old furnace all over with soapy water to see if there were any gas leaks. He found some bubbling under the control valve (the small box on the front of the furnace where the pilot light is). He red-tagged our furnace, disconnected the gas, and said we would have to get the control valve repaired. Great. I called a couple places on Angie's list (including one place that came up under \"gas leak repair\" that didn't even work on furnaces). The third call was a charm, and I found Manny Sr. & Jr. at Apollo Heating and Ventilation. They were right on Geneva Avenue, just down the hill from my home at the top of South Hill Boulevard. I spoke with the receptionst and explained our situation, but she said they didn't have anyone available until the following day. I pressed a little more and she offered that I could try to call back around noon when Manny, the owner, would be there. Manny Sr. was very straightforward on the phone. He made time for us and he sent his son, Manny Jr. up within an hour or so. Manny Jr. arrived prompt, clean, polite and professional, and most important he was very skilled at his trade. He diagnosed the problem with the leaking control valve and he took the time to explain how they worked (there's a bladder inside and if it gets punctured, the valve needs to be replaced). He miraculously had a replacement control valve in his van, and he had the old one off and replaced with the new one in less than 20 minutes. The heat was back on! Manny cleaned the area around the furnace and gave me a very reasonable bill for $389 (I think the part was around $250, the service call was around $100). We're SO glad we didn't have to replace the furnace. Manny said that if we maintained our furnace it could probably last another 10-20 years. I'm a very happy (and relieved) customer and I can whole-heartedly recommend Manny Jr. and Sr. to anyone in the area who needs help with their furnace. Thanks, Manny & Manny. You guys are great!"},"url":"https://www.angi.com/companylist/us/ca/san-francisco/apollo-heating-and-ventilating-reviews-349818.htm"},"position":6},{"@type":"ListItem","item":{"@type":"LocalBusiness","name":"A B Mour Development","address":{"@type":"PostalAddress","addressRegion":"CA","addressCountry":"US"},"review":{"@type":"Review","author":{"@type":"Person","name":"Deanna B."},"reviewBody":"Alan gets our highest rating for diagnostics, problem solving, and professionalism. His work was methodical, the end result was excellent, and we very much appreciated his considerable efforts to keep the costs down. We will absolutely use his services again and highly recommend him and his team. We had two projects and Alan completed both of them. Our upstairs bathroom had a soft floor near the shower which turned out to be due to water damage. However, the source of the water was not clear. One contractor suggested we demo the entire bathroom and remodel it for $35k-$50k. Another suggested that he could spray something to slow the dry rot. Only Alan suggested starting by identifying the source of the leak. After eliminating several possibilities, I made a couple of suggestions which Alan rejected as "too expensive". Finally, he opened the outside wall to expose the plumbing and there found the source of the leak. He made the repair and when the wall was closed up, the stucco repair was flawless. Our downstairs exterior door from the laundry room gets heavy weather during storms. Over the years water had come in and the floor was damaged with dry rot. The original contractor made several attempts to make the door water tight but was unable to do so. A specialist in weather stripping declined the job as impossible. I suggested to Alan that we might need a new door but he rejected that option as "too expensive". With a new threshold, and by making the door close more tightly, he solved the problem at minimum cost. Alan and his workers were very responsive, prompt, and professional. Highest marks.

I had such a disastrous leak! I even tried to turn off the house water and it still leaked. I'm so glad I could get Dale Plumbing to come out over the weekend. He was very efficient, he knew how to do it and he made it really simple. I would definitely use them again!

I am giving three stars because they estimated the cost to be almost 250% higher than what the actual cost was to fix the issue. I am sure there are customers out there that would just accept any bid however, please get multiple beds for these projects, especially when working with this company as they will inflate the cost to take advantage of the situation.

FAQs for gas leak repair projects in Discovery Bay, CA
Yes, most states require a plumber to be licensed, and for good reason. Hiring an unlicensed plumber could lead to poor quality work, costly future expenses, and potential code violations. Check our state licensing tool to review the local plumber guidelines.
As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification, which include:
The owner, principal, or relevant manager passed a criminal background check
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
Paying to advertise their services
Meeting any other eligibility criteria required by Angi
Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.
Fixing a gas leak costs about $45 to $150 per hour for a plumber or gas line specialist. The job’s overall cost will vary depending on the location of the leak. A leaky junction or connection behind the stove or dryer will likely cost about $120 to $170. But for a leak that requires a gas fitter or plumber to excavate a pipe in the yard, the cost could rise to $1,500 to $5,000. Keep in mind that gas leaks are very serious issues, so don’t hesitate to contact a plumber or gas line specialist immediately.
Fixing a gas leak can take anywhere from one to 24 hours, depending on the location and magnitude of the problem. A gas line specialist or gas plumber should be able to give you an estimated time to completion once they evaluate the situation. If your city’s utility company works to fix a gas leak, it will likely have information available about the anticipated time for gas service to be restored.
The cost of repairing a gas leak depends on the type of leak, its severity, and how difficult it is for the repair technician to reach it. Some of the most common gas line repair costs, on average, include:
Cap a gas line: $75–$150
Gas system inspection: $150
Pressure test: $75–$500
Damaged or corroded pipe: $6–$7 per linear foot
Repair gas leak: $120–$5,000
A local natural gas plumber, gas fitter, or gas line specialist should fix gas leaks. Installing gas lines and connections improperly can lead to dangerous gas leaks and explosions. Only a certified plumber or gas line specialist should run gas lines. This is not a job to try out DIY skills, so hire a professional gas plumber or gas line specialist immediately to find the cause of the leak and fix it quickly.
