"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

Your house may be cold even if the heat is on because of bad insulation, gaps in doors, small holes pulling hot air from the home, or excess humidity. The heater itself might be malfunctioning. For this problem, you’d need to talk to an HVAC pro. If you have a gas heating system (most do) this should be considered an urgent job as natural gas could be leaking in your home.

An expansion tank must always be installed on the supply side, which is the side where the boiler sends water out to heat the systems. That placement allows the water to push against the air and condense properly as it is heated, then circulated through the system. Professional installers can recommend the best place on the supply side for an expansion tank.

There are several common types of HVAC systems that you may have, including split systems, hybrid HVAC, duct-free systems, packaged heating and air, geothermal heating, or even portable units for heating or cooling. If you aren’t sure which type is in your home or are looking to install something different, you should consult an HVAC pro to determine which option is right for your heating and cooling needs.

It's possible that your oven's gas ignitor will wear out before the rest of the appliance. An ignitor may last about eight years before it needs replacing. In some cases, cleaning the ignitor to remove any built-up food and debris may help to prolong its life. Replacing the ignitor in a gas oven costs an average of $200.

Deciding whether to repair or replace your HVAC system largely depends on its age, the cost of repairs, and its overall performance. If the system is over a decade old and requires frequent or expensive repairs (e.g., totaling over $5,000), replacement is often the more cost-effective choice, especially if the warranty has expired. It is usually worth repairing a newer system, but if it is approaching the end of its typical 15- to 25-year lifespan, replacement might be a better long-term investment. Signs that you may need a replacement include increased humidity, higher energy bills, uneven heating or cooling, and excessive dust. Before deciding, ask your HVAC contractor to check if any parts are covered under warranty, which could save you money on repairs.
