"The technician at Ridgeback was able to fix a mini-split we had installed by another company 3 years ago. The company that installed it refused to fix it and offered to install another unit if we paid for it. They were terrible to deal with so it was a pleasure to find a company that was dependable and good at getting the job done. I would highly recommend Ridgeback to anyone!"

"Had an issue with a broken pull out shower handle. After assessing the issue, the plumber could not replace the old style pull out without risking damage to the pipes. I did my research and knew that this was a possibility due to the age of the handle. Aris first came on a Friday soon after making the request. After the assessment, and the recommendation to replace the internal pipe to a rotating handle, he was able to return early Saturday to finish the job. All in all, I have to say Aris was great in the way he explained the work and the timeliness of getting it done. I would definitely call again if any future plumbing issues come up."

"These guys rocked, from the time I called on a Friday, to the install of our brand new furnace the following Tuesday! Technician-Scott and Ryan were prompt, friendly, informative and professional. The quote/estimate given was fair/reasonable and in the end was what we paid. Installers-Oscar and Kevin were prompt, friendly, informative, professional, quick and did an outstanding job. Thank you to everyone at Elevated Comfort for your great service! I would definitely recommend them to anyone needing HVAC work to be done!"

"Service plumber arrived on site, on time and was ready to begin. He was friendly and professional. He was fully aware of the problem and what needed to be done. He acquired the necessary parts and changed them accordingly as proficient as possible. Our bathroom sink drain issue was completely resolved and ready. Thank you Eric for a great job!"

"This is a family owned small business. They are friendly, professional, punctual, and really know their stuff. All at a very fair price. My AC had been getting worse every year until last year. HVAC Utor came out and fixed it. It ran better than ever before. This year it was just blowing air so I called again. Same great service as last year. Rachel kept me informed so I knew when they would be here. The problem turned out to be the new thermostat I had installed a couple of months ago. Diego had it figured out and fixed in 15 minutes. I can't say enough good about this company and the people who run it. They're the best!"

"The team of four was very professional and performed an excellent job in a record period of time. Just one day to take the old furnace away, replace all the old boots and duct work and install the new furnace. They paid a lot of attention not to damage or dirty the floor/carpet. I am very happy with their performance. They may not be the cheapest on the block but it was all worthed and you only have to do that once in your lifetime."

Boiler Repair questions, answered by experts

The radiators closest in proximity to the boiler heating system will heat up first. Radiators in rooms farther away from the boiler will take longer to heat up and may be the coolest rooms in the house. The radiator unit itself should heat up evenly; otherwise, there may be trapped air inside it.

Some of the signs of HVAC issues include rising energy bills, rooms not cooling or heating properly, loud noises when in operation, and signs of condensation. To illustrate, if you’re wondering how to stop condensation on air vents, you’ll need to have your HVAC inspected. 

Once you know where your bleed valves are and how to use them, bleeding out heaters is a quick process. Expect it to take around 10 to 20 minutes, possibly longer if you have a lot of heaters or are still learning how they work. If you have a central bleed valve on your boiler, the process still takes the same amount of time. Make sure you have any keys necessary to turn the bleed valves on. Without bleed valves, the process should take around three hours.

Annual servicing, checking for leaks, and maintaining proper pressure extend the system’s life.

There are many signs and symptoms to look out for that can indicate that your HVAC system needs repair, including the following:

  • Your indoor air is uncomfortably hot or cold.

  • Your energy bills suddenly increase without explanation.

  • Your AC is blowing warm air or not blowing air at all.

  • You notice leaks around your HVAC equipment.

  • Your equipment makes unusual noises during operation.

  • You notice strange odors coming from your equipment.

  • You notice that the humidity in your home is higher than normal.

  • The thermostat no longer seems to match the actual temperature.
