Best boiler repair pros near Frederick, MD

"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."

"Just had an emergency visit to replace capacitor in one of my two HVAC units. Was able to schedule my favorite tech Kevin through the excellent front desk staff. Called in early morning and same day repair work - and Kevin fixed the problem even though the house electricity suddenly cut off halfway through the visit due to the remnants of Hurricane Debby coming through. Our family been with Holtzople since 2008 with the installation and maintenance of two TRANE heat pump units. We have always been extremely happy with Holtzople. Their expertise and knowledge of HVAC operations is superb. But most importantly, from the HVAC techs and Kevin to the front office staff, the people at Holtzople are kind, helpful and genuinely interested in taking care of us. This shows in our semiannual service plan visits as well as the rare emergency needs that pop up like the situation discussed above. And we have been very happy with our TRANE HVAC units. We will have Holtzople as our HVAC company forever. We highly recommend them to all our local friends and neighbors in central Maryland. Simply a great company with great people. 👍"

"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!"

"The plumber was berybeasybto deal with and very experienced. He did a great job."

"Sean was very prompt in responding to me request for service and did his absolute best to accommodate my schedule at my convenience. He was very flexible overall and helped get my AC repair ASAP after it was broken. This was especially helpful since it was getting warm outside! He was on time for all of our appointments and communicated what needed to be done/fixed clearly, so I wasn’t left with a huge bill that I wasn’t expecting. Expectations are very important and he seems to understand. I would highly recommend Sean and/or his team for any issues you might have for a cost effective and friendly solution. Thank you so much for your help Sean!"

"I reached out to Angi’s to find a HVAC company to help with my AC that was blowing hot air in the summer. I got super lucky when I found MSR Heating and Cooling. They arrived on time and assessed my situation. I appreciated the time they took to explain the issue in ways I understood as well as recommend the best option for me. The estimate quote was fair and there were no surprise expenses to repair my unit. I can’t thank the owner, Moises enough for a job well done. His professionalism, knowledge and skills are reflected in the quality of work performed. I would highly recommend this company for your next repair."

"I called Buric (on advice of friend/neighbor) when A/C wasn't working and I asked what to expect in their charges. The guy on the phone told me they charge a flat $95 (or $99?) for driving out here. So I asked if they charge by the hour or half hour. No, he said, by the job. He couldn't give me an estimate because he didn't know what was wrong. So, a technician came out and diagnosed my unit (which blew air but didn't get cold) as old & dead and needing replacement. So, in my mind, there was really there was no job outside of replacement. In their mind, they did a job by taking 10 minutes to look at the unit and tell me there was nothing to be done for it. So, instead of charging me $99 for coming out, they charged me $230 for coming out AND telling me the unit couldn't be fixed. That irritated me. Then I asked for a bid for new system. The guy went out and talked on the phone to his boss and come back with a written bid. I later compared it with my second bid from another co. Buric's bid was higher than the company I selected, but not enough to sway me if I had liked their way of doing business. However, the previous (over)charge, which was not explained by the guy I spoke to when I first called, left such a bad taste in my mouth I couldn't go with them. So that extra $130 they made cost them around $5000. I hope it was worth it to them. BTW, if I had gone with them, they would have subtracted the $230 from the bid, but I just couldn't get past it. So, I am not saying anything about the quality of their work--it may be just fine, but I don't like the way they did business."

"I recently had a HVAC and water heater installation by Carroll Mechanical, Cris Lopez and his team. They were very respectful of my home and professional throughout the install. I am grateful and appreciative of working with the owner on deciding the HVAC unit to be installed. I found him to be the consummate professional, a person of integrity, transparent, responsive to my questions and willing to work with me to gain my business. I highly recommend Carroll Mechanical."

"The technician was great, thoroughly took his time figuring out what would be needed to complete the job."

"Awesome! Someone answered right away when I called and told me a technician could be here in 30 minutes. It was actually only 20 minutes when Dan arrived and he was extremely professional and pleasant. He diagnosed the problem on our two systems, explained everything thoroughly with a reasonable repair estimate, then completed the work. He was here for about an hour and now the house is nice and cool, while it’s 95 degrees outside!"
