Des Plaines is where A+ HVAC and Refrigeration is based. Our office sits on Hanbury Drive, which means Des Plaines customers usually get the quickest response we're able to offer anywhere — and it means we know this city's housing and its quirks better than any company driving in from another suburb.
We're a family-owned company that has served Illinois since 2015, and Des Plaines is our home city — our office is on Hanbury Drive, so Des Plaines calls are the shortest drive we make. Every repair is a flat price you approve before we start, carried out by licensed, insured, background-checked technicians and backed by a full warranty.
The Homes We Work On in Des Plaines
Des Plaines is largely a post-war city. Much of the housing stock went up between the late 1940s and the 1960s — brick and frame ranches, split-levels, and Cape Cods — with older frame homes closer to the downtown Metra area and newer infill scattered throughout.
That era means forced-air gas heat is the norm here, often through ductwork that was sized for the equipment available in 1955. When homeowners upgrade to a modern high-efficiency furnace, the limiting factor is frequently undersized return air rather than the furnace itself. We also see a lot of original-location basement furnaces and water heaters, which matters in a city where parts of the low-lying land near the Des Plaines River have a long history of flooding.
Problems We See Most Often in Des Plaines
Every area has its own recurring faults, driven by when the housing was built and what was installed at the time. In Des Plaines, these are the calls that come up again and again:
- Furnaces and water heaters installed low in basements that have taken on water
- Undersized return ducting limiting the performance of newer high-efficiency furnaces
- Original 1950s–60s ductwork with leaky joints in unconditioned crawlspaces
- AC condensers sited tight against the house on narrow post-war lots
- Aging 80% furnaces near the end of a second decade of service
Commercial HVAC & Refrigeration in Des Plaines
Des Plaines has a substantial commercial base for its size — the Oakton Street and Mannheim Road corridors, the hotels and restaurants that serve O'Hare traffic just to the south, and the hospitality business around Rivers Casino. That mix keeps our commercial refrigeration team busy with walk-in coolers, prep tables, and display cases, plus rooftop cooling on the retail and office stock along the main corridors.
For any of it, downtime is lost money and — with refrigeration — a food-safety exposure, so we treat commercial calls as priority work and carry the common parts needed to finish most repairs on the first visit.
Seasonal Considerations in Des Plaines
Being minutes from O'Hare means Des Plaines gets the same brutal exposure the airport's weather records show: sub-zero snaps in January and stretches of humid 90-degree days in July. Sitting in the Des Plaines River valley also makes basement moisture a year-round consideration — humidity control is often as valuable here as raw cooling capacity.
Whatever the season, the goal is the same: get your Des Plaines home or business comfortable again quickly, and be straight with you about what it needs.

Des Plaines HVAC — Frequently Asked Questions
How fast can you get to a Des Plaines address?
Des Plaines is our home city — our office is on Hanbury Drive — so it's the shortest drive we make. Same-day service is the norm here for both residential and commercial calls.
My Des Plaines basement has flooded before. Where should a new furnace go?
Where the basement has a history of water, we'll look at raising the furnace and water heater on a platform, relocating them, or at minimum moving the controls above the historic water line. We'll walk the space with you and give you the options and costs before anything is ordered.
What is your service call or diagnostic fee?
The diagnostic fee is $79 residential / $149 commercial, and it's waived in full when you proceed with the repair.
Do you charge by the hour?
No — we use a fixed-price-per-repair model. You get a straightforward, upfront price for labor and parts before any work begins.
Do you service window AC units or mini-splits?
Our AC service covers central, ducted, and commercial systems only — not window units or mini-splits.
Are your repairs warrantied?
Yes. Most parts carry a 12-month warranty, and labor is warrantied 30+ days depending on the repair.
