"Arizona Rug Co. recently completed cleaning and restoring our rugs for us and we could not be more impressed with the quality of their work. The older and larger of the rugs no longer looks 42 years old. I recommend, as a designer, taking care of quality rugs in order to enjoy them fully. It also needs to be said that this company has a varied selection of rugs available from the well stocked showrooms, both in Tempe and Scottsdale, with knowledgeable sales staff."

"I had a great experience with JDL. They were able to come out the next day to repair my furnace. The technician, Ire, was very professional, easily diagnosed the problem, and made the repairs right away. He also demonstrated to me that the problem was fixed and made sure that I could perform basic maintenance going forward. I highly recommend JDL."

"When our boiler went out in the middle of a snowstorm, Troy came to our rescue! Incredibly professional and kind - especially given the terrible weather, he arrived quickly, diagnosed the problem almost immediately, replaced the board and restored our heat! All of this at a very reasonable price! Troy- thank, thank you, thank you! Needless to say, Troy has permanent customers- we can’t recommend him more highly!"

"I'd been experiencing allergy concerns and decided to have an air quality test performed for mold primarily in my home. Sometimes the air in my home, seems to cause my nose to run and eyes become somewhat irritated. The gentlemen, first listened to all my concerns and gave me some suggestions, due to another problem I was experiencing in my attic.  He looked in my attic and gave a few suggestions to correct a problem there. He said that he too noticed some nasal irritation in the air, as well. I wanted to first start by ruling out  MOLD, as the problem. He did not pressure me in performing an air test, at all. It was totally my decision and we both agreed that at least I would know whether to rule mold out or remediate a mold problem, if necessary. So I gave him my consent to conduct an air quality test. He said that he would conduct it on the inside ( top level hall area) and outside ( front of garage) to compare results. Two sample vials with air samples from the two locations were collected using a machine with free standing stand.  He left and assured me that he would physically  deliver the two samples that evening to an outside facility for a diagnostic analysis and said that I'd get the results on Tuesday, via email.  On Tuesday, I did receive the results, which showed that I had no MOLD. However, it did show that I had something in the air which could explain the symptoms I'd been experiencing. The report was very detailed and pretty easy to read and comprehend. I also called their office and a woman pulled up my results and reassured me that there was not a Mold problem. He left his card, should I need further service and he would quote an estimate,should I use his service for the attic problem. He was very professional, polite, and very attentive to my situation.

Boiler Repair FAQs, answered by experts

It takes about five to 10 minutes for heat to reach a radiator, then about one hour until the radiator fully heats up a room. The exact duration depends on the size of the room and how far away the radiator is from the boiler heating system. Heating up an entire house could take up to two hours.

The absence of heating or hot water, unusual noises like banging or gurgling, and visible water leakage are key signs. Abnormal boiler pressure, flame irregularities (for gas boilers), or pilot light issues may also signal trouble. Frequent cycling, soot or staining, and unusual odors, particularly gas-like smells, should not be ignored. Modern boilers often display error codes or lockout mode upon detecting issues. Uneven heating across radiators and rising energy bills without increased usage can further point to problems. Prompt attention to these signs is essential to prevent further damage and ensure safety.

The most important sign of a boiler problem is something happening unexpectedly, which is why regular boiler maintenance is important. Unexpected problems can include strange smells, new leaks, and unexpected noises that your boiler wasn’t making before. Additionally, if a boiler keeps shutting off or can’t maintain a specific temperature range, it’s time to call in an expert.

Yes, cleaning a boiler is essential for its efficient and safe operation. Over time, boilers can accumulate dirt, rust, sediment, and mineral deposits, reducing efficiency, increasing energy consumption, and causing potential breakdowns. Cleaning involves removing these deposits from various components like heat exchangers, burners, and pipes. Neglecting cleaning can also lead to corrosion and decreased life span. Regular, yearly maintenance, including cleaning, ensures optimal performance, lower energy bills, and a safer heating system. It's best to consult the boiler's manual or hire a professional technician for cleaning to ensure the job is done right.

Some high-quality steam boilers come with 10-year warranties, but a well-installed, properly maintained model can last at least 20 to 25 years. Learning how to clean a boiler, getting an annual professional service, and keeping up with maintenance and repairs on your heating system are all important for getting the most out of your model.
