Glad I hired them 10 years ago and still happy with their service today. I'd recommend them to anyone looking to improve their hot water system.

After getting estimates from 4 HVAC contractors, I went with HVAC Performance by W&A to change over…read morethe gas forced-air HVAC in a 101-year-old home I purchased, to all heat pump. Mr. Marroquin's price was extremely competitive; he seemed to know a great deal about systems and equipment, and I really liked his "all in" pricing because the electrician work came bundled into the price. (Drywall repair was NOT included - but that turned out to be okay because I'm having solar panels put in later and that site survey crew was thrilled about pre-cut holes, LOL!) This was a BIG project; removal of a gas furnace and replacing it with 7 indoor air handlers and 3 outdoor compressors. The entire project took about one month to complete - almost exactly what had been predicted. Even before he could get started on the new project, the existing "whole house" heat pump system that serviced the upstairs of the 3,100 sq. ft. house broke down on a 95-degree day in D.C. Mr. Marroquin came out and worked all day on a Sunday to get it going, as the upstairs system would be the only AC for the house for the month it would take to change over to the new system that would service the main floor and lower level. He rejuvenated the existing system and gave it a comprehensive servicing for a very good price. We had to store equipment on site for a bit, but I liked that Mr. Marroquin wanted ALL of the equipment in hand before he started the project so we wouldn't be left hanging by supply chain issues. For the new install project Mr. Marroquin stayed in constant contact so I could trust he and his crew would be there on the days he'd said they would, or else he would let me know promptly of changes in schedule. I was on work assignment on the opposite coast, so he, I and my house sitter were able to work out a good system for giving him access to the house via a key box and us remotely resetting the alarm at the end of each workday. Mr. Marroquin was extremely conscientious about securing the house and texting me until I confirmed the alarm was reset. He tented EVERYTHING with plastic and put down tarp to protect the wood flooring (there were appreciative messages hand written on the tarp thanking me for my business!) Even as the owner of the company, he was pretty much the last person to leave the job site every day, taking time to sweep and even wet-clean some areas. Because of the configuration, there needed to be conduit cover for lines on the front of the house. I was very concerned about these being too noticeable and detracting from my curb appeal. Mr. Marroquin took great care to obtain paintable line-set conduit for these and he color-matched and painted them PERFECTLY to blend in with the color of the stucco. He was also responsive to my concerns about condensate from the outdoor compressors draining too close to the home's foundation and on my rear deck. He was creative, coming up with inconspicuous clear tubing and PVC piping systems to drain the water away. When the job was done he brought HIS MOTHER to the house to help with the final cleaning - so impressive! As you can tell, I'm very pleased with HVAC Performance and Wilson Marroquin. The only areas where the service could have been a bit better were around "paperwork" issues. Like most contractors who work from sun up to sundown, paperwork is often the last thing they get to. I never did get a fully completed contract before the work started, and I had to make a pest of myself to get the final invoice with cost breakouts so that I could claim my rebates and energy credits on my taxes. Also, Mr. Marroquin was very enthusiastic about Daikin brand - and the units ARE very quiet from what I'm used to and the price was good. But the plastic housing of the air handlers was apparently extremely delicate and the crew cracked the condensate pump access slots on every single unit! Mr. Marroquin and I had to have several talks about how to conceal this. Hooray for white duct tape - not ideal, but not a huge eyesore either.

Review of Conform Heating & Cooling/Plumbing (Owner: Troy)…read more Troy, the owner of Conform Heating & Cooling/Plumbing, came to my home on June 15, 2026, after my insurance company assigned him to perform a diagnostic inspection of my water heater. As part of my insurance deductible, I was required to pay $70.00, which I paid via Zelle on the same day as his visit. After the inspection, I waited several days and then contacted my insurance company to check on the status of my claim. I was informed that they were still waiting for Troy to upload the diagnostic report. Approximately two weeks later, I contacted the insurance company again and was told that they still had not received the required report. At that point, the insurance company advised me to contact Troy directly. Beginning in early July, I spoke with Troy approximately three to four times per week requesting that he submit the diagnostic report. During these conversations, he repeatedly claimed that he was experiencing IT-related issues that prevented him from uploading the report. I then asked him to simply email the report to me so that I could forward it to the insurance company myself. Unfortunately, despite numerous phone calls and text messages, I never received the report. Each time we spoke, Troy assured me that he would send it later that evening, but he never followed through on his promises. By August 4, 2026, I had still not received the diagnostic report. My calls and text messages were going unanswered, and I eventually had to call from a different phone number just to reach him. When I finally spoke with him, I explained that it had been nearly two months since the inspection and that I had repeatedly requested the report. Rather than addressing the issue professionally, Troy became angry, raised his voice, stated that he was busy, and ultimately hung up on me. As a result of his failure to provide the diagnostic report, I was forced to cancel my claim and start the process over with another contractor assigned by my insurance company. This caused significant delays, unnecessary inconvenience, and wasted time. Meanwhile, my family, including my children, has been without a functioning water heater during this process. In my opinion, charging a customer for a diagnostic service and then failing to provide the resulting report is unacceptable. I paid $70.00 for a service that ultimately produced no usable result for me or my insurance company. Based on my experience, I cannot recommend Conform Heating & Cooling/Plumbing. The lack of communication, failure to deliver the required documentation, and unprofessional behavior created a very frustrating experience that could have been avoided with basic follow-through and customer service.

Jake was our plumbing technician and he did a thorough job replacing copper pipes with color-coordinated tubing in the upstairs bathroom. Installed new shut-off valves to the vanity, toilet and tub faucets and even vacuumed before he left. We had a water pressure problem after he left, and Jimmy Gusky had another tech at the house the next day to resolve it - the solution was really simple and had to do with sediment settlement near a valve when the water main was off for repairs. It was a bit embarrassing, frankly, to have a plumber open the valve when we could have done so ourselves to clear the sediment and restore water pressure. Both plumbers were great about explaining their work and the rationale behind it while they were in our home. I recommend this company for the thorough repairs and friendliness, professionalism of their techs.
