"From the beginning - Sean was extremely responsive to all of our questions and very flexible with scheduling the service. He installed our new humidifier on the furnace, provided instructions on how to operate it, and offered multiple tips for keeping the system running efficiently. He also offered a very fair price. He was very professional, and we would definitely hire him again!!"

"From not having a water supply for my whole home bypass humidifier, to having a repaired, new water supply line and instant winter comfort. All in less than two hours. Thanks Edmond and team for getting me taken care of right after I arrived home from work. Wealth of knowledge, too, about HVACs warranties, and other good general advice for first-time homeowners like myself! Glad to have signed-up tonight as a member - eligible for discounts tonight and future maintenance services. Highly recommend!"

"I contacted Bluestar Air Mechanical for a second opinion after an appointment with Air One. I have a Carrier HVAC system, and the Air One technician recommended a complete system replacement, claiming the blower was bad, the furnace control board needed replacing, and that there were other issues. Since replacing the HVAC is a big investment, I wanted to get a second opinion. It was only after comparing the service from Bluestar that I realized Air One may have been pushing for a new system sale or lacked the expertise to properly diagnose and repair the actual problems. Isaac, the technician from Bluestar, spent about an hour thoroughly diagnosing and fixing the issues. He found burnt wiring in the furnace and discovered that the wrong capacitor had been incorrectly installed in the AC. Isaac replaced the burnt wiring in the furnace and the capacitor in the AC. After these repairs, my Carrier system was back up and running—without the need for a costly replacement. Bluestar, and Isaac in particular, demonstrated professionalism, expertise, and honesty. They focused on resolving the actual issues instead of pushing for an unnecessary system replacement. I highly recommend Bluestar for their reliable service and Isaac’s thorough and knowledgeable work."

"I can’t say enough excellent things about Lance, the service technician who came out! We just purchased our first home so imagine our surprise when barely a month in the large grand chandelier fell from the ceiling in the early morning. I was going to replace it myself but remembered our home inspection pointed out some instances of aluminum wiring in the house so I thought I should have an electrician confirm the outlet was properly done before I go mucking around in the ceiling. Although it cost me an emergency dispatch fee, they had someone in my house first thing the very next morning. Lance was prompt and just so amazing - very kind and careful with keeping our house clean, taking care of the floors and finishings and really went above and beyond to help a very frazzled young family try figure out the mess they just purchased. While he was at our house we opted to have him also see if he could remove two outlets in the dining room from a dimmer switch so they can be always on. He explained the pricing up front and I knew what the job would cost as a final number before he began any work. For the first job, I was very impressed with how thorough and complete he was in taking care of not just the replacement chandelier, but even with safely disposing of the now broken old chandelier for us! He even offered to help move some boxes for the Salvation Army pick-up we had scheduled - I was just blown away by how kind and helpful he was! For the second job, I was so very pleased that he took the time to really figure out what was wrong. He ended up spending almost three hours discovering several issues - including things like faulty attempts at mitigating aluminum wire connection points in several outlets that we received confirmation prior to settling on the home had been fixed. He was able to come up with creative solutions to safely leverage what was already available to solve our problem and the best part is he really took the time to not only do it right, but to explain everything as he went and really helped me learn more about my house and how I can discover and resolve similar problems in the future. Being someone who is always trying to learn I really appreciated his willingness to answer my questions and share his depth of knowledge and experience! In the end, even though the job was a lot longer than either of us thought it would be, and even though the original cause for the emergency dispatch was already resolved, Lance made sure he stayed until we had a solution in place and we still only paid the initial quoted price! Yes, the price did seem a bit high compared to what I’ve seen on other provider’s quoted rates. However, the work really is just that good - absolutely worth it AND charging by the job instead of the hour takes all of the guessing out of how much you will need to pay, not to mention covers situations like this where the job ended up taking quite a bit longer than originally anticipated. We couldn’t be happier. We were so pleased with the service that we also signed up for their annual service plan to avoid emergency dispatch fees in the future and to get their annual safety inspection. There’s a lot of uncertainty associated with buying our first home, but at least we now know who we will call for all of our electrical needs!"

"Happy Holidays all! Please use my Holtzople (H) review to help you address your HVAC needs! Last summer, my Trane AC unit failed. Corey W (H) was the tech that came out to the house and troubleshooted/resolved the problem (leaking refrigerant). He also advised on probability of future repairs. Sadly, the unit performed well for only a short time before failing. It was time to consider my options. Repairs were becoming more frequent and costly. Tyler (H System Designer) visited and walked around my house inspecting my current HVAC system. We discussed repairing or replacing my ailing AC unit. He recommended replacing with a split ductless system and emailed a quote for 1. Enhanced Mitsubishi hyper heat mini split system (system) 2. Favorable financing options - low interest rates and affordable monthly payments. The install took a week. H’s crew arrived each morning, respected my property, and worked as a team to carefully install the new system. With gratitude, John"

"My experience with him was top notch. He was accommodating to my schedule. I work nights and he was willing to come to my home in the early evening instead of normal business hours. He assured me the fix of the leak would hold until the end of summer but there was a chance that I may need a new unit next summer since the unit is over 10 years old and the leak was pretty severe. I had no other trouble with the unit the rest of the summer. His price was reasonable and he was friendly and efficienct. If I need a new unit next summer I will definitely use Tetteris Heating and Air for the replacement."

"We initially called Davis and Davis when our A/C started blowing hot air. They came out three separate times, charged us money for repairs that didn't work, then decided we needed a full replacement for $4,500. We called Buric for a second opinion. Tom arrived on time, took 20 minutes to (correctly) find the problem, told us we didn't need a replacement, and repaired it for just over $400. It works great to this day. He pretty much restored our belief that honest technicians still exist in the world and saved us like $4,000. Only had one experience with them, but will always recommend them."

Humidifier Repair FAQs, answered by experts

A whole-house humidifier can positively impact energy consumption by improving heating efficiency. During colder months, humidified air feels warmer, which allows you to lower your thermostat without sacrificing comfort. This adjustment can lead to significant energy savings as your heating system works more efficiently. However, it's important to use the humidifier judiciously, as excessive humidity could potentially strain your cooling system in warmer months.

Cleaning and replacing filters and ducts reduce allergens and enhance air quality.

NATE-certified technicians may charge slightly higher service fees compared to non-certified technicians. This is because NATE certification signifies a higher level of expertise and professionalism, often leading to more efficient and effective HVAC repairs and installations. While the upfront cost may be marginally higher, NATE-certified technicians can potentially save you money in the long run by reducing energy consumption, preventing frequent breakdowns, and extending the life span of your HVAC system. When looking for a local HVAC company to hire, it never hurts to ask about NATE certifications.

Whole-house humidifiers work, but the home itself determines their efficacy. If you have a drafty house or an old home with wooden floors that leak air and moisture, the humidifier must work much harder to keep moisture levels constant. Because of this, we recommend doing an air test of your home to determine the best type of humidifier and any work that needs to be done to install it. 

It improves air quality, prevents dry skin, protects wood furniture, and enhances overall comfort.
