About this company
Su'Coy Heating, AC & Duct Cleaning operates out of Washington, DC, serving the District and Prince George's County, Maryland. This is primarily an HVAC company — heating, cooling, and duct cleaning are the core business — with mold inspection, testing, and remediation offered as part of their indoor air quality services. Owner Derrick Conyers has run the company since 1996.
The mold testing page describes a multi-method approach: air sampling with spore traps, surface swab and tape-lift sampling, bulk sampling of building materials, and moisture mapping with infrared cameras and hygrometers. They offer post-remediation verification testing. The website mentions NADCA certification for duct cleaning and EPA-approved testing methods. They claim same-day and 24/7 emergency mold inspection. The HVAC background gives them a natural connection to duct-related mold problems — several reviewers specifically mention mold found in air vents being removed during duct cleaning.
Derrick Conyers is quoted on the website talking about building trust in the community. The company also runs the Su'Coy Community Learning Center, an HVAC training program. One reviewer (victor brown) describes being a current student and praises the hands-on training. Multiple reviewers reference being referred by friends or neighbors, suggesting word-of-mouth drives their business in DC.
218 Google reviews at a perfect 5.0 stars is striking. That volume with zero rating drag means either exceptional consistency or aggressive review management. The review content skews heavily toward HVAC and duct cleaning work rather than mold-specific jobs, though several reviewers mention mold remediation and water restoration together.

Review consensus
Reviewers consistently praise punctuality, clear explanations of the work, and same-day responsiveness. Derrick is named by Robert for personally handling mold removal at his mother's apartment. Jay and Marques are named by Liliana Sanchez for duct cleaning and HVAC maintenance, with praise for being respectful of her home. Mallory Meaney describes mold removal from an air vent during duct cleaning. Ruth Washiembi mentions mold remediation and water restoration after a leak. Dominique Campbell highlights Su'Coy as the only company out of three that could explain the job clearly. Torrey Caccavale, a Local Guide with 36 reviews, notes a within-one-hour response for a leak repair.
1 found across 218 total reviews at 5.0★. Aaron Miranda left the sole negative review, complaining about a robocall system and difficulty reaching a human, describing staff as disinterested. The owner responded that they have no record of a call from this person, do not use an automated call system, and petitioned Google to remove the review. Miranda has only 2 total reviews and is not a Local Guide. With no other negative reviews in the dataset, this single complaint cannot establish any pattern.
The review volume (218) is significant, but the content is notably repetitive — many reviews are brief endorsements ("great service," "very professional") without specific details about what work was done. A cluster of 5-star reviews appeared in mid-March 2026 from reviewers with low review counts (1-3 reviews each), several on the same day (March 17-18). This does not prove anything, but the pattern is worth noting. The mold-specific reviews are a small fraction of the total; most describe HVAC repair, AC service, or duct cleaning.
Derrick Conyers (owner — positive, named by Robert for personally handling mold removal). Jay (technician — positive, named by Liliana Sanchez for duct cleaning and HVAC maintenance). Marques (technician — positive, named by Liliana Sanchez for duct cleaning alongside Jay).
Ask Derrick to personally oversee any mold remediation project, since he is the only staff member reviewers have connected to mold work by name. Get an independent mold test before signing a remediation contract. Press for specifics on mold-related certifications — the website is clear about NADCA credentials for duct cleaning but vague on remediation qualifications. Su'Coy's strength is the ability to connect HVAC and air quality problems to mold, which standalone mold companies cannot always do.
Keep in mind
- Su'Coy does both mold testing and mold remediation. A company that tests for mold and then sells you the remediation has a financial incentive to find problems. Get an independent mold inspection before committing to their remediation services.
- This is an HVAC company first. Mold remediation is one of many services they offer, not their sole focus. The vast majority of reviews describe heating, cooling, and duct cleaning work — very few describe mold-specific jobs in detail.
- 218 reviews at a perfect 5.0 stars with only 1 negative (which the owner disputes as illegitimate) is unusually clean. The absence of any substantiated complaints makes it hard to identify weaknesses or patterns.
- The website lists Montgomery County, Northern Virginia, and a wide list of DC and Maryland neighborhoods. Confirm response times and availability for locations at the edges of their stated service area.
- The website uses the term NADCA certification for duct cleaning, but does not specify which mold-related certifications their technicians hold for remediation work. Ask about mold-specific credentials.
