Nearby HVAC Services in Ashburn

"From day one, the dedicated and professional staff of Willis Builders was a pleasure to work with. Our initial interactions were with Matthew Willis, the owner, who talked with us about what we wanted to do, provided suggestions on how to do things less expensively, and handled the financial end of things. At Matthew's suggestion, we chose to do a "design-as-you-go" approach. We had a general idea of what we wanted to do and then bought our cherry cabinets at auction as a set. The kitchen was then designed and rebuilt around the cabinets we purchased. Doing it this way saved us thousands of dollars on custom cabinets, but is not for the faint of heart because you have to be flexible in what you want and you have to be willing to make major design decisions almost every night of the first few weeks of the project. This also requires excellent communication between you and the men doing the work. Once work began, it was Marcelo, our project lead, who handled everything, although Matthew was available at a moments notice if we needed him, which we never did. I can not say enough good things about Marcelo. First of all, his workmanship is impeccable (and we are picky). He is professional, reliable, hard working, communicative, patient (especially when we changed our mind about things in he middle of the project), and an overall nice guy. Much of the work was done by Marcelo and Luis, a wonderful team who work well together and also worked well with us. At times, other members of the Willis crew were at the house lending their expertise to the project. Everyone was wonderful. Marcelo and Luis worked six days a week on the project (arriving a bit later on Saturdays so we could sleep in.) If working on Saturday had not been convenient for us, they wouldn't have done it, but we wanted to get the project to completion as fast as possible. They always worked their schedules around our schedules and tried to be as un-intrusive as possible. Every night at the end of a long day they spent time cleaning up so that the dust was at a minimum. They did this even when I encouraged them to leave the mess and go and get some rest. It was amazing how little dust there was even when walls were brought down. We chose our own granite supplier and fabricator. Marcelo orchestrated the installation, however, and was here with me when that occurred (at 6pm on a Friday night). This was good because when there was a problem with the granite, he was able to help assess the situation and help resolve it with the installers on the spot. Aside from the granite, the Willis employees did everything except installing new and refinishing our old hardwood floors. This was subcontracted out, but Marcelo made all of the arrangements with the subcontractor. Overall we are thrilled with the results and the experience of our renovation. Of course any major renovation is stressful, but ours went about as smoothly as humanly possible. This is predominately due to the professionalism of the men that Matthew Willis has assembled into a wonderful team. We are looking forward to our next project with them."

"The yearly HVAC inspection was exceptional with stellar customer service. Donnie called and let me know he was on the way. There was a thorough inspection and explanation of my Lennox A/C system and provided recommendations. He and Zack answered all of my questions and was professional throughout the whole visit. Highly Recommend!"

"Jiffy answered my call immediately and had an HVAC specialist call me soon after to determine the problem. The next morning the Jiffy senior HVAC specialist came to my house, assessed the situation (the other company had placed a "danger" sign on the furnace) and informed me that I should not be using the furnace at all given the potential for carbon monoxide poisoning. The weekend was ahead of me and cold weather so I took a chance and continued to run it. On Monday morning, Jiffy HVAC specialist came out and began the long and tedious process of removing the old furnace and installing the new one. The senior HVAC specialist was able to provide advice on how to heat the back room which was added on to the house with no insulation, which makes that room cold. He suggested a solution that has proven to be perfect. Better heat circulation throughout the house. The senior specialist continued to check on the installation throughout the day. By 6pm all was done. Both the HVAC installers and the senior specialist were friendly, helpful and pleasant. I will use them again and highly recommend them."

"Two handymen installed plywood boards in the attic. The boards were supplied pre-cut, but due to lack of uniformity in the joists and other HVAC related equipment in the attic the two handymen had to do additional measuring and cutting to cover the surface with the plywood appropriately. It was a hot day and very hot in the attic. They did a good job especially considering the very hot conditions. We are satisfied with the work performed."

"We hired MW Construction for our major renovation project after meeting with nearly a dozen contractors. Greg Marks sold us on their services with his straightforward style and innovative solutions to maximizing the space in our tiny row house. We had initially toyed with the idea of just doing the basement or just doing the bathroom, but decided to get it all done with at once - this was a great decision. Greg's brother Drew was the project manager throughout our project (one of the things we love about MW is that it's a small, local, family owned company). He was on site nearly every day and we met with him in-person once a week or more. He was very patient with our many, many questions and responsive via text, email and phone calls. We had a few snafus with our designer during material selection; however, during our project MW ended their work with her and hired a new designer, who made great recommendations for us. Although some part of nearly our entire house was torn up for three months, MW ensured that we could continue living there throughout the project and was respectful to our work schedules. They worked almost every Saturday and right up to the July 4th holiday to complete our project. Our one frustration would be that, at times, we wished that some "executive decisions" weren't made without us. For instance, a window in our back enclosed porch which was set to become part of the kitchen was moved a few inches to accommodate an adjustment in cabinet design that was discovered after the walls were opened. We would have been fine with moving the window if explained the situation as it occurred, but instead found out from the neighbors mentioning the fact that we were missing siding on one side of our house. Thankfully, the cost of the additional siding work was not passed on to us.There were a few instances like this where a less involved homeowner may have not cared, but this being our first reno, we would have appreciated a heads up. To their credit, MW was apologetic and continued to work on communication throughout the remainder of the project. There were also on-going issues with the HVAC and ancient duct work in our house throughout the project, which several of their HVAC specialists worked extensively on and seem to have been addressed. They finished on time and on budget, which is nothing but a miracle in the construction industry! We have recommended MW to many people since our renovation, including two who have signed contracts and now have beautiful spaces in their home. While our house has been totally renovated, we would not hesitate to use them again for a project."

"I called in the evening to schedule a repair and received a call back very quickly. Cornerstone found a time that worked for me. They gave me a timely call to notify me the technician was on his way. He was very professional and took care of my issue. I signed up for their annual service plan I was so impressed!"

"I was incredibly impressed by the exceptional professionalism and customer service from 4 Service Pros. They were immediately responsive, always on time, and - most importantly to us - took the time to work with us to find a solution that met our needs and budget. They will be my first call on any of our other projects going forward."

"I currently have a 24 year old 100,000 BTU Carrier Gas furnace and a 11 Seer rated 11 year old AC unit. I am in the market to purchase a complete HVAC system for my home and narrowed it down to two contractors. My home was built in the 1970's and is about 2000 square feet including the finished basement. Michael and Son Estimate on Carrier Unit INFINITY 17 - 3Ton 36,000 BTU 17 Seer rated 96 GAS FURNACE INFINITY - 80,000 BTU, Up To 96% AFUE, Multi-Position, Two Stage, Variable Speed Gas Furnace INFINITY REMOTE ACCESS TOUCH CONTROL SYSTXCCITW01-A (Wifi) Carrier HUMIDIFIER HUMXXLFP PERFORMANCE? AIR PURIFIER PGAP Did not provide details on Coils They will give me serial # to submit rebate to my power company to get back 1K I didn't choose Michael and son because another reputable contractor provided a slightly better configuration for about 4K less. But I appreciated them coming out and the professionalism that was provided by their comfort consultant. The consultant was very detailed and did a great job explaining everything."

"It went very well. They came to the house and provided a quote that was less than other quotes we had received for the same quality Carrier system. They also arranged interest free financing with Carrier. After we agreed to purchase it from them, they came a couple of days later and installed the system in the course of the day. They also removed all of the old system, cleaning up the work area. When it turned out that the thermostat they installed had a defect, they came back the same night and replaced it. The system has been functioning well and has saved us considerable monthly fees in electricity. They came in September (the system was installed in July) to do a semi-annual check up."

"We had another company (that we previously used) give us a quote and it seemed really high. Tristate was then recommended by a good friend of ours (his parents had used them for over 20 years). They were able to quickly schedule a sales person and technician to determine if the system was repairable and how much a new system would cost. We were giving 3 options at varying costs and given the details on the system. They also went over the tax credits and manufacturer incentives for each system and even filled out the rebate and tax credit forms for us. The install went well, they had everything up and running quickly. We had a few noise issues with the system and they were quick to have a technician out at no additional cost. Technicians and salesperson were all friendly."
