What D & G Heating and Cooling does
D & G Heating and Cooling, Inc. is a family-owned HVAC service company founded in 1954 and headquartered in Livonia, Michigan. It operates as a factory-authorized Bryant dealer selling, installing, servicing, and maintaining Bryant heating and cooling equipment for residential and commercial customers across four Southeast Michigan counties (Wayne, Washtenaw, Oakland, and Livingston). The company runs a single physical showroom at 19140 Farmington Rd, dispatches field service technicians for on-site work, and offers 24/7/365 emergency service through a dedicated phone line.
The company's core product portfolio spans Bryant air conditioners, gas furnaces, heat pumps, boilers, and water heaters, complemented by an indoor air quality lineup (whole-home humidifiers, dehumidifiers, air purifiers, ventilators, and the iWave bi-polar ionization system) and smart thermostats (Evolution Connex and Housewise Wi-Fi). The Bryant Evolution System serves as the premium integrated platform, connecting thermostats, HVAC equipment, and air quality components under a unified communications architecture. The company also sells ductless mini-split systems, geothermal systems, split systems, and packaged HVAC systems, enabling coverage across most residential and light commercial applications.
D & G generates revenue through five streams: hardware sales of HVAC equipment, professional installation services, repair services (covering all makes and models), annual maintenance subscriptions under the Comfort Assurance Program (starting at $179/year), and individual service calls. Pricing includes free estimates for new installations, financing options, and promotional coupons. The company employs word-of-mouth, Google reviews, its company website, and special offers as its primary marketing channels, with deep reliance on its 70-year brand reputation and family-owned identity. No external funding, acquisitions, parent company, or public listing exist; the business is now in its second generation of family leadership.

D & G Heating and Cooling competitors and assessment
Company assessmentDirect peers
- Christian Brothers Heating and Air Conditioning: Residential HVAC service franchise offering installation, repair, and maintenance across multiple U.S. markets with a customer-experience focus similar to D&G's family-owned positioning. Comparable target customer (homeowners) and full-service HVAC offering.
- One Hour Heating & Air Conditioning: National residential HVAC service franchise providing installation, repair, and maintenance with 24/7 emergency response — directly parallel to D&G's service offering, customer base, and emphasis on on-time, satisfaction-guaranteed service. Brand/franchise structure differs but operating model is closely aligned.
- CoolToday: Regional residential HVAC, plumbing, and electrical service company operating across the Southeast U.S. with a multi-location service model. Comparable in service mix, residential customer base, and emphasis on same-day/emergency response.
- Johnstone Supply: Cooperative wholesale distributor of HVAC equipment, parts, and supplies serving independent contractors and dealers nationwide. Comparable in the parts-inventory and equipment-supply functions D&G performs as a Bryant dealer, including the role of stocking service parts for quick-turnaround repairs.
- Bob's Heating & Air Conditioning: Mid-size regional HVAC contractor offering residential and light commercial installation, repair, and maintenance across a multi-county footprint with a similar single-brand-or-multi-brand dealer model. Comparable in customer segment (homeowners), service mix, and reliance on local reputation.
- R.E. Michel Company: HVAC wholesale distributor selling equipment and parts to contractors and dealers across the Eastern U.S. Comparable in the dealer/distributor role D&G plays for Bryant equipment and parts inventory, though R.E. Michel serves as a B2B supplier rather than an end-consumer contractor.
Broad incumbents
- Lennox: Major residential and commercial HVAC manufacturer competing in the premium high-efficiency segment where D&G's Bryant Evolution offerings compete. Lennox's Dave Lennox Signature Collection and dealer program represent the most direct equipment-level alternative to D&G's Bryant premium positioning.
- Carrier: One of the largest global HVAC manufacturers (residential and commercial) and a direct competitor to Bryant in the premium equipment segment that D&G sells and installs. Carrier's dealer network competes with Bryant's for contractor mind-share and consumer brand pull in the same households D&G targets.
- Trane: Major global HVAC manufacturer with an extensive residential dealer network competing directly with Bryant. Trane's premium product positioning, brand recognition, and dealer economics are the most relevant competitive benchmark for a Bryant-authorized contractor like D&G.
- Rheem: Major HVAC and water heating manufacturer with residential product lines that compete directly with Bryant offerings D&G installs. Rheem's dealer network and pricing model represent another alternative equipment source for Southeast Michigan homeowners D&G targets.
