Two systems do most of the work in a typical home, and they're the two we repair most. Here's what to expect when you call.
When your AC hums but won't cool, blows warm air, or keeps tripping the breaker, the fix is usually a single worn component. We test the system, find it, and replace it, often the same day. Pricing is upfront, and we'll tell you honestly whether a repair is worth it on an older unit.
Most furnace breakdowns come from a handful of parts: flame sensors, igniters, inducer motors, and control boards. We find the one that failed and fix it, usually in a single visit. You'll get a clear quote first, plus a safety check of the combustion and venting while we're there.
Wondering if it's bad enough to call? These are the most common heating and cooling problems we fix in homes across the area.
When the AC runs but the house won't cool, the fault is almost always one specific component. We find it and fix it fast.
AC repairIf the blower runs but the air never warms, or the unit clicks without lighting, the failure is diagnosable in minutes with the right tools.
Furnace repairA system that runs constantly but never satisfies the thermostat is burning money. Seasonal maintenance restores the efficiency you paid for.
Maintenance & tune-upsR-22 refrigerant, rust on the cabinet, a compressor on its second capacitor, these are signs the smart money is on replacement.
System replacementIf some rooms get dusty faster than others, leaky or dirty duct runs are the likely cause. We inspect, clean, and seal what we find.
Air duct cleaningAdditions and bonus rooms rarely get enough duct capacity. A dedicated ductless head fixes the problem permanently.
Mini-split installationMost repair calls are diagnosed and fixed in a single visit because we stock the common parts, capacitors, contactors, igniters, motors, on every truck.
We don't cut corners. Our team is experienced, background-checked, and fluent in every major brand, from a 20-year-old gas furnace to the newest inverter-driven heat pump.
If a $40 capacitor fixes it, that's what we'll tell you. We quote repair and replacement honestly, with real numbers, and let you choose, no scare tactics, no pressure.
Installations get the full treatment, real load calculation, correct line sets, sealed and balanced ductwork connections, and a complete commissioning test before we leave.
Rockville HVAC has been keeping homes comfortable in this community and the surrounding MD towns for years. We know this area inside and out because we live and work here too.
Every technician on our team is seasoned, vetted, and trained across air conditioners, furnaces, heat pumps, and ductless systems. We tailor every recommendation around the system you have and the way you use it. When the AC quits, you deserve a team that can be there fast, not a franchise dispatcher hundreds of miles away.
Speak directly with a local HVAC expert. Upfront pricing, no obligation.
From the first call to the final airflow check, our method is built to solve the problem completely the first time.
Call (240) 896-8292 and we'll get you a price quote, often within a day. A few quick questions, cooling or heating, what the system is doing, how old it is, and we'll book a time that works for you.
A technician evaluates the unit on-site, confirms exactly what's wrong, and lays out a plan and a price before any work begins.
Most repairs finish the same visit, our trucks carry the common parts. Replacements are installed to code with proper sizing, sealed connections, and clean workmanship.
Before we leave, the system is tested end to end and your questions are answered. Seasonal tune-up plans are available to protect the investment.
Upfront pricing · Same-day service available
A house with no AC in a heat wave gets dangerous, not just uncomfortable. Here's what our team does the moment you call to restore your comfort fast.
You call (240) 896-8292. A real person picks up, assesses your situation, and books the soonest available technician.
There's no waiting around for days. A fully equipped technician pulls up to your home, often same-day, with the parts already on board to diagnose and start fixing right then.
On the first appointment, we test the full system. Our technician checks the parts that fail most and shows you exactly what failed and why.
We don't disappear once the visit is done. We follow up to confirm everything is holding, and for systems in their later years we'll suggest the maintenance rhythm that keeps them reliable instead of surprising you.
"Half our house was always five degrees warmer than the thermostat said. The tech found crushed flex duct and a dampener stuck half-closed, then set up a new smart thermostat and actually taught us how to use it. Every room finally feels the same."
"Our restaurant's rooftop unit failed on a Friday with a full weekend of reservations booked. Their team had us cooling again before the dinner rush. They clearly understood what downtime costs a Rockville business, and they came back the next week to fully service the second unit. They've got all our locations now."
"When our old furnace was on its last legs, they walked us through converting to a heat pump instead of just quoting a like-for-like swap. Our winter bills dropped noticeably the first season, and we got cooling out of the same equipment. Zero regrets on this one."
Good HVAC service comes down to doing the small things right. These are the commitments that earn Rockville HVAC repeat customers and referrals year after year.
Hands-on experience is the real benchmark for HVAC work. Every technician on our team has years of field experience across air conditioners, furnaces, heat pumps, and ductless systems, ensuring your home is serviced according to proven best practices.
An oversized system short-cycles itself to death; an undersized one runs nonstop and never satisfies. Our team walks you through the sizing and installs it to local code, permits included where required.
Our team focuses on keeping systems alive with simple, scheduled care. If you want years more from your current equipment, our seasonal tune-up plans handle the checks that actually extend equipment life. It's that simple. This approach is one reason we maintain a 4.9-star rating across hundreds of reviews.
