When we bought our home, we knew one of the oil furnaces was disconnected and assumed it needed to…read morebe replaced. The inspector said the other two were beyond their normal useful life but still worked. What we didn't expect was that we couldn't get the property insured unless we agreed to replace all three heating and cooling systems within a month! We scrambled to find a good HVAC company that could do the job for us. Enter Design Flow Heating and Cooling. Working closely with us, they recommended three cost-effective heat pumps. They then removed and disposed of all the old systems and installed the new ones well within the thirty-day limit. But once we moved in, we discovered the upstairs wasn't being cooled uniformly, and in fact the previous owner had blocked the vents in some places in an attempt to balance it. The pros at Design Flow diagnosed the problems promptly and installed new ducts and returns to draw the hot ceiling air away from areas where the temperature was too high. It made such a difference! I recommend Design Flow Heating & Cooling without reservation!

I decided to go with Design Flow after only meeting with Brian one time. He came out very quickly…read moreto diagnose the problem. Rather than just look at a couple of things and then say everything was shot, he continued to troubleshoot for over an hour before coming to that conclusion. I got a couple different quotes from companies I had had work done before, but Design Flow was cheaper, by far. This isn't always a good thing. Some people will say that you get what you pay for. I feel like I got so much more than what I paid for. At a minimum, you only have to look at the pictures to see the quality and care of the work they did. More than the quality, they were quick. The team was just here Friday, but they were in by 7 and out shortly after lunch. Very impressive. Now I have a brand new unit that is much more efficient than my previous unit so I shouldn't need much HVAC work in the future, but if I do, I know that I'm not going to be shopping around. I only have one call to make.

He was able to come out the very next morning, diagnosed the issue, and had it completely repaired in less than an hour. Pablo was personable, professional, and communicative throughout the entire process. He clearly explained the problem, answered all of my questions, and made the repair experience stress-free. It's not often you find someone who combines technical expertise with such outstanding customer service. I highly recommend Pablo for any appliance repair needs and will definitely call him again in the future. Outstanding service from start to finish!

While he was here fixing our dryer, I told him about the AC, someone told us to upgrade the whole system, but after putting some freon, our house is 73 degrees again.

But when they removed the tape from my vents, they took paint off of of 10 vents and when I raised the issue asking for some redress, I was pointed to the disclaimer in the estimate.

The initial inspection involved looking at my daughters vents, then looking at the HVAC before stating that the cost of the repairs and work done might not get the results I'm hoping for. In the future, It would be helpful if they ran through a few preliminary questions or pictures of the unit to see if a trip out is worth the time. Before the technician left I asked a few more questions before he suggested a Home Energy Audit. I'm hopeful that the home energy audit could put me on a better path to resolving the cooling issues in my home. Edit: Rob contacted me after my review and explained a few other details where now I feel the information that he provided was worth the cost.

My HVAC system was ~17yrs old and working, but not efficiently. I decided to replace our system…read moreand asked for quotes from five companies. I picked Exxel to replace our system based on these: 1. Very detailed quotes, model number, seer, eer, afue, capacity, etc. everything that I needed to research and compare. 2. Detail explanation of the warranty period. 3. Explanation of what would happen on the day of installation, again very detailed, so no surprises. 4. I asked for multiple quotes based on two stage and variable stage units and seers. Bob wasn't annoyed that I asked for multiple quotes so I can research and compare. He provided multiple quotes in less than 24hrs. Other companies seem annoyed that I asked for multiple quotes and didn't really provide what I asked for. I felt that he understood as consumers, we all do research before purchasing high price items and he was not annoyed with that fact. 5. I had additional questions (probably some stupid ones that hvac professionals get all the time) and Bob patiently answered my questions. At the day of the installation, they arrived within their estimated time. Bob and Greg were very professional. They called in the morning and gave me the arrival time. Since we don't wear shoes in our house, I had covered our floor with tarps, too my surprise they put their tarps on top of my tarps. It was totally fine with me considering they observed that we don't wear shoes and respected that and tried to keep our floors clean. The install took about eight hours and I was glad that there was no pressure to sell me other stuff. They cleaned up the area before leaving. I highly recommend Exxel and wouldn't hesitate to use them again.....when it's time to replace our upstairs heat pump.

We also were having issues with out upstairs unit having poor air distribution between bedrooms. Ray (I think he's the owner) came out for a bid. Super knowledgeable and gave me an estimate that was 35% of a previous bid (who was clearly trying to scam me!). He also listed to my concerns about the upstairs duct issues. Even though this was not within his scope, he offered to call a reputable company (he often work with) that repairs hvac ducts, have this guy come out when our ducts were being cleaned so he could explain the issue in industry terms! The actual cleaning was great. I had four guys and it took them 8 hours for my 4 units. They were all very polite and did their best to vacuum up debris after the process (I did vacuum a second time- but I'm a clean freak). HIGHLY recommend this small business!
