GUEMRI Appliance Repair responded to my request within the hour, which was a late Saturday afternoon. A technician showed up 10:30am Sunday, and my problem was repaired in less than an hour. He explained the two circumstances which caused the problem, how they most likely occurred (poor workmanship by previous contractors) and how he made additional provisions such that not only would the problem be fixed, that it should not occur in the future. The price was so reasonable I paid a little extra. I would definitely recommend this company, and will use them again in the future if the need arises.

After three disappointments with previous contractors either not showing, overcharging, and lack of response, our company was assigned Logan Mechanical. I can honestly say they were great. I appreciate their professionalism and true passion for the job. They could have easily tried to get one over as other companies have, but instead they came in, fixed the issues created by another company, as well as the original concern. Not only were they prompt and helpful in explaining the process, they provided different options for our situation. Because of their great work, we have happy clients now, with working AC ;)

Our thermostat and heating system suddenly stopped working on one of the coldest days of the winter. We initially called our home warranty company, who has been reliable in the past, to request an emergency service technician for the repair. After several hours of waiting anxiously, the warranty company informed us they weren’t able to locate any available HVAC repair technicians in our area...they said the reason was because it is a Sunday and there is an unusually high demand for heating system repairs. Disappointed, we decided to try Thumbtack, and within a very short time of submitting our request, Andrew called us back, came by our house and got our heating system back up and running. We are very grateful for his responsiveness, professionalism, value, and quality of work. Thank you, Andrew!

After meeting with four different general contractors, Mr. Marvin Guzman with Baiza Construction, Inc showed his best attitude to take part on a serious complete home improvement we had for our 1956 home. He didn't only provided a quick estimate, But time frame to complete and over all his price. My project was based on a full 2 bathrooms remodeling, plaster walls removal/replacement, insulation, plumbing, electrical, kitchen remodeling and about 2500 square foot of hardwood floor installation. My best recommendation to future hires and families of his great quality work. My contract worth 86k were put on the best hands.

I texted Lassaad to help with a cord replacement in my gas stove. He responded immediately and 20 min later he was at my place (earlier in the day I waited four hours for another contractor). Lassaad arrived on time, brought everything he needed and got to work right away. He fixed the problem in 10 mins, and even though he initially quoted me $140 he ended up charging me only $75 because the job was less complex than he initially envisioned. He is professional, courteous and knows what he is doing. Definitely will hire him again.

Matt tiled my bathroom walls and floor. He was very fair in his pricing for his excellent quality of work. He showed up every day for work exactly on time and worked hard to make sure I was happy with his work every step of the way. Of all my years in working with general contractors, Matt's professionalism was my best experience. In terms of his skills with tile, he fixed existing problems with my bathroom in terms of level, tile placement, and severe lippage. When he was done with his work, my bathroom was beautiful! The tile placement gave the bathroom a better sense of space, the floor and walls were level, and there was no lippage. He suggested some aesthetic choices which I went with and the end result was beautiful. Finally, Matt was honest with me in terms of work specialty that he was not comfortable with; that is, I had some aesthetic choices in mind, but he was straightforward with me and said he was unable to do that. I appreciate that honesty, whereas some contractors says they can complete certain special work when, in fact, it's a stretch and does not come out with the quality we hope for. All in all, I would recommend Matt for tile work. He is a strong 5-stars in terms of quality of work, professionalism, and, on a personal level, he is just a very nice man and is easy to talk to.

The company moved my boiler pipes in the basement to make way for a new exterior door. The work was fast and professional. The price was higher than I expected, however, multiple companies simply refused to do the job, at any price. The company coordinated with my remodelers, which was a great help. Again, many other HVAC companies I approached for an estimate told me that they just didn't do remodeling jobs, only repair and service. Overall, I'm glad I found David and ComfortFactor and I will keep them in mind for my future HVAC needs.

Robyn was great. He showed up on time, was tremendously professional and knowledgeable. He was able to help me with multiple jobs. He is officially my new appliance repair go to! He was able to fix a dishwasher in about 15 minutes. That three companies came out to repair (american home shield contractors) and couldn’t repair it in months. I highly recommend him.

We initially came to thumbtack to find someone that could diagnose our problem with lack of airflow upstairs. He came to me one late evening and noticed immediately what was wrong with my system. He noticed that I needed a new furnace for my unit. I had an old 2 ton unit and he informed me that I needed a 4 ton energy efficient unit to get max airflow. He came in and installed my unit in like 3 hours when initially he said 6 to 8 hours. He was also reasonable with price. After the unit was installed, he noticed that two of my upstairs ducts were either separated or not there. I will get an estimate to that soon. Only problems were: -I usually deal with contractors who have contracts with customers. Ray only used invoices. -Communication could be excessive sometimes but he wanted to be in constant communication with changes. -The old furnace was left by my dumpster. I informed Ray that we don’t like added trash and equipment added to our dumpster area. But, the furnace was gone by the next morning. Overall, Ray is the right person for your AC needs!! And he has the experience to back it up! Will hire again!

Working with Salvation LLC was a wonderful experience. Ernesto and his team are outstanding. In fact, Ernesto found a creative solution to my HVAC/water heater issue that several other HVAC companies had not even considered. The finished installation was beyond my expectations; pre-installation preparation and post-installation cleanup could not have been better. I have had HVAC/water heater work done in the past but Salvation's work was superior to all of these other companies. The work was done at a reasonable price in a timely manner and Ernesto made sure that I understood all that would be involved in the installation. I highly recommend Salvation! I have already scheduled some additional HVAC work with Salvation and they will absolutely be my go-to HVAC company going forward :-)

Replacement of HVAC, heater and A/C located in attic. The Hughes team evaluated what I needed, educated me on the options available and provided the most competitive price by far. The work was done in one day and works great. They have lots of experience doing HVAC work and it shows.

Brian was absolutely amazing! My biggest concern when dealing with contractors is their honesty and integrity. Brian found what problem existed in the system and basically saved us thousands of dollars. I can honestly say if I had hired someone else they probably would've taken advantage of us and charged us more. I will recommend Brian to everyone!!

After posting a project for installation of an Aprilaire 2310 media filter and new duct work, I immediately recieved a response from Revolution Heating and Cooling with a very affordable estimate (more so than several local HVAC contractors I had reached out to before). From the very start, Curtis provided excellent service from proposal to the actual installation. He arrived on time and was very friendly as well as knowledgeable. Installation was quick despite challenges with the size of the furnace closet. Will definitely be using for future projects!

Nasir was very responsive and arrived at our house at the requested time. He was able to confirm what the problem was with our HVAC system and was able to complete the repair with material on his truck. His service fee was reasonable and the overall cost for the repair was very competitive. He also offered a solution to avoid future problems & repairs. I would recommend Nasir for HVAC diagnosis and repair.

We had a list for our home inspection and he performed each task and wrote a detailed response in the invoice. He was very professional, courteous, and had great work quality. We will be hiring him again for maintained of our system.

Can't say enough about Norlan! My deck was in dire need of repair. When I purchased my home 4 years ago, the deck needed to be repaired, but I didn't have the money to do it at the time. When I was able to take care of it, Norlan responded and did everything we wanted and more. His team was professional, friendly, made sure I was happy with the work, and gave me an amazing price! After he finished the deck, we asked him to do more work. You won't regret using Norlan Construction. Great job!
