BPM Heating, Cooling & Plumbing holds Maryland HVAC Master License #75803 and installs ductless mini split systems from LG, Mitsubishi, Fujitsu, Lennox, and Samsung — brands that require factory-certified training to install correctly. BPM is an LG Pro Platinum Dealer and a Lennox Powered by Samsung Specialist, both of which confirm demonstrated installation quality and give customers access to enhanced manufacturer warranty options. The team at BPM has over 100 years of combined HVAC experience, and installation crews of up to four technicians are deployed so the job is done in a single visit.

However we end up at your door, the experience runs the same way. Every BPM visit means licensed HVAC and plumbing professionals, clear communication, honest pricing, and technicians who respect your home and your time. Here’s what to expect, start to finish.
Tell us what's going on, and we'll get you on the schedule at a time that works for your day.
You'll get a confirmation and an "on the way" notification before your technician arrives — so you're never left guessing or waiting around.
Your technician walks you through what they're going to do and what it costs before any work begins — in plain language, with no pressure.
We complete the job, clean up after ourselves, and make sure everything's running right before we leave.
You already know what the problem is. There is a space in your home that your existing system has never handled well — or was never connected to at all. Maybe it is the finished garage you converted into a workspace, and by noon in July it is 90 degrees in there regardless of what the thermostat says. Maybe it is a sunroom addition, a bonus room over the garage, or a second floor that runs ten degrees hotter than everywhere else no matter how long the system runs. Maybe you have a detached structure — a rental unit, a studio, a workshop — and running ductwork to it would cost more than the project is worth.
You have already looked at the alternatives. Another window unit rattles, blocks the view, and has to come down every October. A portable unit moves the problem around but does not solve it. You have done enough reading to land on a mini split as the right answer. What you are not sure about yet is who does this well in Frederick, what it actually costs, and whether the installation will be done right the first time.
That last part is the real concern. A mini split is not a small purchase, and the installation matters as much as the equipment. A system that is undersized for the space, placed wrong, or wired incorrectly will underperform from day one — and the problems are not always obvious until you have lived through a full summer with it. If something does go wrong after installation, ductless mini split repair is available from the same team that installed the system.
BEST experience!!! BPM Heating & Cooling was my 4th quote for a new furnace and a/c unit. They explained everything completely, did not give any run around on my questions, provided a reasonable quote and reasonable finance options, if needed. Further, they went above and beyond to make sure the home was comfortable until the install date. All BPM staff were informative and polite at every step. I highly recommend BPM Heating & Cooling!!

I can’t say enough good about BPM Heating, Cooling & Plumbing. We bought a house, and on the day we moved in there was mold in the mini-splits that another company failed to remediate. We couldn’t move in until the mold was remediated. BPM sent out a highly experienced technician the next day who took care of 7 mini-splits (big job). From the first call to the company to the technician they sent, start to finish, exceptional experience.

Certifications & Licensing
Manufacturer dealer status and state licenses aren't decorations — they affect which warranty terms you get on new equipment, who's allowed to pull your permits, and whose installation work the manufacturer will stand behind.

Manufacturer dealer certifications require demonstrated installation quality, verified customer satisfaction ratings, and completed factory training. Premier and Authorized status also unlocks enhanced warranty options on new equipment — terms that aren't available through uncertified installers. The LG Pro Platinum designation is LG's highest contractor tier, covering cold-climate and inverter-driven systems specifically.
The process starts with an honest sizing conversation. BPM does not pick a system based on a rough square footage estimate. The technician looks at the actual space — ceiling height, insulation, sun exposure, how the room is used — and tells you what the system needs to be. If a single-zone unit covers your situation, that is what gets recommended. If multiple indoor heads make more sense for the coverage you are after, BPM walks you through the tradeoffs before anything is quoted.
Once you have agreed on the configuration, installation is typically a single-day job. A crew arrives, handles the line set, mounts the indoor and outdoor units, makes the electrical connections, vacuums the refrigerant lines, and commissions the system before leaving. Before the crew is done, the technician walks you through the controls — how to set modes, adjust airflow direction, use the remote or app — so you are not figuring it out on your own the first night.
A few things worth knowing about how BPM works:
When the job is done, the system is tested under load. You know it is working correctly before the crew leaves, not three weeks later when the first hot day arrives.

Installed mini-splits. They really do mean satisfaction guaranteed. I wasn’t happy at first with some of the way the outside coverings looked, and they redid everything multiple times until I was completely satisfied.

Wonderful work! Extremely professional team, very knowledgeable, and kind crew. Was provided options and educated on why certain brands have different pros and cons. Two mini splits were added to my upstairs and my world has changed! I can now sleep in my bedroom again and work in my office. So worth it!

We loved these guys. They were very friendly and knowledgeable. We switched from having no AC and an oil furnace to all electric. They put in three mini-splits in our lower level and a duct unit in the attic for the upper level. They even recommended a great electrician. Very pleased with the work done and highly recommend them.

A single-zone mini split installation in Frederick typically runs between $3,000 and $5,500 installed, depending on the brand, the efficiency rating, and the specifics of the installation — how far the line set needs to run, whether the electrical panel needs work, and how complicated the wall penetration is. Multi-zone systems with two or three indoor heads run higher. BPM offers instant online pricing for HVAC equipment at bpmhvac.com, and financing is available through Nymeo Federal Credit Union if you want to spread the cost. The quote you receive before the job starts is the price — there are no mid-job additions unless something genuinely unexpected comes up, and if it does, you hear about it before work continues.
Most single-zone mini split installations are completed in one day. Multi-zone systems with multiple indoor heads may run into a second day depending on the number of units and the complexity of the line set routing. From the first call, BPM can typically schedule the installation within a few days. If you are in a situation where the space is unusable in the meantime — a room that is genuinely too hot or too cold — mention that when you call; BPM has been known to adjust the schedule to accommodate urgent situations.
Square footage is a starting point, not an answer. The right system size for a finished garage in Frederick depends on how well it is insulated, how much sun it gets, whether it has windows and how many, and how you use the space. An oversized unit will short-cycle — it cools the air quickly but does not run long enough to pull humidity out, so the room feels clammy even at the right temperature. An undersized unit runs constantly and still cannot keep up on the hottest days. BPM sizes the system to the actual space before anything is quoted, so you are not guessing after the fact.
Most mini splits require a dedicated 240V circuit. If your panel has capacity and an open slot, that circuit can usually be added as part of the installation or by an electrician coordinated alongside it. If your panel is already full or undersized — common in older Frederick homes — you will need a panel upgrade before the mini split can go in. BPM identifies this during the initial assessment, not mid-job, and will point you to a qualified electrician if the electrical scope falls outside what they handle directly.
The inverter-driven cold-climate systems BPM installs — including LG and Samsung models — maintain effective heating output at outdoor temperatures well below freezing. Frederick winters regularly drop into the teens and occasionally lower; these systems are rated to operate efficiently at those temperatures. That said, a mini split in a poorly insulated garage or a space with significant air leakage will work harder than one in a well-sealed room. BPM will tell you honestly if your specific space has characteristics that would limit winter performance, and what the realistic expectation is before you commit.
Frederick County requires a mechanical permit for mini split installations in most cases. BPM pulls the permit and coordinates the inspection — you do not need to manage that process yourself. The job is done to code, the inspection gets scheduled, and you have documentation that the work was done correctly. This matters if you ever sell the house; unpermitted HVAC work can complicate a sale.
Mini splits need the filters in the indoor head cleaned every few months — it takes about five minutes and keeps airflow and efficiency where they should be. The outdoor unit should be kept clear of debris. Beyond that, an annual professional check — refrigerant levels, coil condition, electrical connections — catches small issues before they become failures. BPM’s Comfort Club maintenance plan covers that annual visit and includes a 20% discount on any repairs; professional mini split maintenance puts you at the front of the line if something does go wrong. On the warranty side: because BPM is an LG Pro Platinum Dealer and Lennox Powered by Samsung Specialist, the systems they install qualify for enhanced manufacturer warranty tiers that are not available through uncertified installers. The specifics vary by brand and model — ask when you get your quote.
