"HD Mechanical did an excellent job. After trying to fix my water heater, the tech offered me two solutions, the first to repair the old unit and the second to replace it. I chose to replace the unit because it was 20 years old. He was able to return in two days and spend many hours at my home. The tech was courteous, professional, explained everything and made sure everything was working properly before he left."

"Michael offered great advice on where to place our new tankless heater and his team did a great job executing. There were a few hiccups that came with replacing the old tank heater and working with the old plumbing of the home, but Jax Mechanical were able to solve any problems that popped up. Michael was also proactive in the initial discussion and found that our PRV needed replacing which was something we were glad he found before it led to any long term issues."

"If you need a reputable honest company for your Cooling and heating system maintenance or repair then you need to call Hutchinson. Orlando is one of the good ones. Honest and tries his best to help his customers. My experience over the last year and a half with trying to get my Air Conditioning unit fixed by other local Temecula/Murrieta companies has been bad to say the least. Two other companies that I called told me that I needed replace my whole system for $12,000 or just my A/C unit for $5,000-$7,000. After waiting a year to try and come up with the funds to get something done I saw reviews on Angies list about Orlando and his company that made me feel that he was an honest guy and I could trust him. From the first call I felt that I was treated like an important customer and they were ready to help. Orlando and his crew came out that day and the next morning and were exceptional in their work ethic. They spent hours in unbearable heat diagnosing and fixing the problem. They determined that the unit was fine and just needed service and a Freon charge. While the previous contractors spent a few minutes looking at it and immediately told me I needed a new system. I don't know what more I can say about Hutchinson heating and air except they are the best and I would recommend them to anyone who needs work done on their A/C. 5 stars, A++++, Excellent."

"Repair was done on my daughter's car who is in college in California, I live in Colorado. The owner spoke with me on the phone prior to doing the repair to explain issues with car. His assessment was consistent with the problems my daughter described to me. The price was very reasonable for all the parts and labor. The job was completed quickly and they stayed past closing until my daughter could get there to pick up car. They accepted my payment over the phone and offered to check her fluids and inspect car periodically in the future for free. I think you will be very satisfied using this garage as this and other reviews have clearly shown.

"⭐⭐⭐⭐⭐ Exceptional Service from Airtime Plumbing, Heating, & Air! I cannot recommend Airtime Plumbing, Heating, & Air highly enough! From the initial service call to the completion of the job, my experience was absolutely five-star. We had an urgent issue with our furnace acting up just as the cold weather hit, and they responded with incredible speed and professionalism. The technician David arrived promptly, was extremely courteous, and clearly explained what was wrong with our unit. He didn't just fix the problem; he took the time to show me what maintenance steps I could take to keep the system running efficiently. What Made Them Stand Out: Punctuality & Communication: They called ahead, arrived exactly when they said they would, and kept me informed throughout the process. Expert Knowledge: The diagnosis was fast and accurate. They fixed the problem right the first time. Fair Pricing: The final cost was competitive and exactly what was quoted, with no hidden fees or upselling. Cle"

"Ryan, the owner from Airtight A/C came right over and fixed our unit asap just before the big heat! He was in and out within the hour..no muss, no fuss and his prices were lower than other places we called in our area. He will be our "go to" technician in future calls for heating and cooling problems. Great, quick service. Five stars easy! Thanks a million Ryan. You saved our lives in this heat! Joe & Alice Skiles"

Boiler Repair FAQs, answered by experts

To bleed a radiator, first turn off the heat to the system. Then, lay a towel under the valve, open the bleed valve, wait 20 to 30 seconds for air to escape, and gently close the valve. You should repeat this process for every radiator you have in your home. Once your radiator valves have all been closed carefully, you can turn them back on.

If you have a closed-system boiler that requires an expansion tank, you cannot safely operate it without one, as this risks extensive damage or even explosions. You must find a way to make room for the installation. Options include repositioning the boiler, rerouting the boiler piping to a more open area, or performing minor remodeling to create the necessary space. If you are unsure whether your boiler needs an expansion tank or how to best accommodate one, it's recommended to have a local heating service professional assess the situation. They can confirm the requirement and suggest the most practical solution.

If you have multiple radiators, start by bleeding a first-floor radiator that is farthest from the boiler. Work your way toward the boiler on the first floor before moving to the next floor, where you’ll again start by bleeding the radiator farthest from the boiler. Continue this pattern for radiators on each floor until they’ve all been bled.

Even if you do everything right, your boiler’s pilot light might not come on. This has a number of possible causes, but the most common is a blocked jet. These jets are small and clog up even with a small amount of debris. You can clean it yourself or hire a pro to replace the component. Other possible causes include a faulty fan and frozen pipes, among others.

If you go to turn it counterclockwise and it won’t turn anymore, it’s open. Like most other valves, you should be able to turn a radiator valve counterclockwise (to the left) to open it and clockwise (right) to close it. To close a radiator valve, turn it clockwise until you meet some resistance and can’t turn anymore, but do so carefully to avoid breaking the valve.
