My Mitsubishi system wasn't responsive and I couldn't figure out the problem. Carlos from Akian came through and checked it out. We found out the breaker was the issue. They got an electrician on site and replaced the breaker within an hour. Carlos also ran a diagnostic and got my system running perfectly. Great communication and follow through. Definitely reccomend.

Very happy with the service. The plumber arrived on time, explained everything that would be done and approximately how long it would take. He was very courteous and put a tarp down and wore shoe coverings while working. I will definitely use this company again.

Update to the update. I am sticking with Akian. They are a big company with many competent technicians. They respond timely. They do their best to make customers happy. It's hard to know when things fail where the fault falls. But they have been responsive and they have fixed issues with little to no charge as appropriate. See below for history. ---- Update to my original review. Some years later, after having them install new heater, water heater, and AC. The heater that akian has since installed 3 years ago has run into problems every year since. One time, one of the vent pipes was not attached properly. It was under 1year since the installation so they fixed it for free. Nex time, it was an issue with exhaust piping. Must have been some other installation errors but since it had been more than a year since installation; we were charged for the repair. And now again, we have cold air blowing from the system and I am calling them. Side story. For the exhaust issue, the first technician they sent misidentified the problem claiming it was because our vents were not fully open. Then Manny, the technician who I praised in my original review was sent; he identified and corrected the problem. So turns out not everyone in their employ is the same. ------- I call about a heating system emergency; our furnace is broken on a cold week. Their earliest availability is in four days. But since it is an emergency, they make some calls, and send over someone immediately. In this day and age, when HVAC companies rarely respond or show up. Manny comes over, identifies the problem, and fixes it. All along, he is honest about what he may or may not be able to do. We are lucky, the current problem was solvable. But he points out that the heater is old. He lays out options for the future; we may replace the flame sensor that caused the current problem if the same issue arises; we should consider a complete system replacements; and he has identified a list of worn out parts if we want to try to extend life of existing system. No pushiness, no BS, just reasonable opinions. I can't know if all their technicians are as knowledgable and capable as Manny. But next time we have HVAC needs, we are calling Akian again.

I DO NOT RECOMMEND THIS COMPANY AT ALL! The company quoted me a $129 diagnostic fee. However, when the technician arrived, he barely did anything other than take a quick look at the equipment. He then told me that the $129 only covered his less-than-30-minute inspection, and that if I wanted any further service, I would have to pay an additional $249. This was completely different from the information I received when I initially contacted the company. To make matters worse, the technician refused to provide me with a quote. I explained that I did not want to be nickel-and-dimed with one charge after another, but he showed absolutely no understanding. His attitude was extremely unprofessional. He acted as though he would refuse to do anything at all unless I agreed to pay the additional $249. In the end, I decided to pay the $129 just to get him to leave. This was an incredibly frustrating experience, and I felt pressured into paying for virtually nothing. Save yourself the time, money, and frustration. I strongly recommend avoiding this company’s services!

Disappointing Experience – Unexpected Fees and Poor Communication I scheduled an HVAC diagnostic appointment with Akian after being told by their office that the diagnostic fee would be waived if I decided to proceed with the recommended repair after receiving an estimate. However, when the technician arrived, I was told a significantly higher diagnostic fee would apply, that it would not be waived even if I proceeded with the repair, and that I would not receive a repair estimate unless I agreed to pay the higher fee. This was completely different from what had been communicated when I scheduled the appointment. My main frustration is the lack of communication and transparency between the office and the technician. I specifically confirmed the pricing and process before booking so I could make an informed decision about whether to proceed with repairs. Instead, I was put in an uncomfortable position during the appointment.

Extremely Disappointing Service -- Poor Communication, Questionable Pricing, and a Complete Lack of Follow-Through I hired this company to address a water leak in my steam heating system. Initially, I believed the problem was with two steam vents that I had purchased myself but was unable to remove because they were seized. The company charged me $450 to install two vents that I supplied, a job that took approximately one hour. Unfortunately, replacing the vents did not resolve the problem. We subsequently identified what appeared to be a clogged line beneath one of the vents. I requested an estimate to repair the problem and was instead given a proposal to replace both lines for approximately $2,150. When I asked why both needed replacing when only one appeared to be clogged, the technician's explanation was simply that the other one could eventually clog. I explained that I wasn't comfortable spending that amount of money unnecessarily and that, as the homeowner, I believed it was my prerogative to determine what work I wanted performed. I also indicated that I might seek another estimate. Later that evening, I spoke with the technician again and explained that I would like to move forward, but requested a revised estimate to replace only the clogged line. He assured me he would speak with the office and get back to me. A week passed. Nothing. What followed was an extraordinarily frustrating exercise in trying to communicate with this company. Their telephone system requires you to leave a message and wait for someone to return your call, with no indication of when that might happen. If you're unavailable when they call, the entire process starts over. The only person with whom I was able to maintain any consistent communication was the manager of their answering service, primarily through text messages. Eventually, he provided a revised price of $1,850 to replace just the one clogged line. This raised yet another concern. The original estimate was $2,150 to replace both lines. Removing what I understood to be approximately 60% of the proposed work resulted in a price reduction of only $300, or roughly 14%. I also asked the manager whether he had the original estimate prepared by the technician so we could compare the two proposals. He responded that they were attempting to contact the technician. I never received the original estimate, an explanation of the pricing, or any meaningful follow-up. Once again, communication stalled. Finally, arrangements were made for someone from their service department to call and discuss my concerns. I explained that I would be available around noon, and they agreed to call at approximately that time. I sat with my phone in my lap from 11:30 a.m. until 1:15 p.m., waiting for a call that never came. What makes this especially troubling is that I have three family members living in my home, a steam heating system that needs repair, and winter approaching. This is not a cosmetic improvement or an optional renovation. It is a necessary repair to keep my home heated. I cannot help but come away with the impression that this company is more interested in the size of the job than in providing responsible, attentive service to its customers. Whether that is actually their motivation, I cannot say, but their conduct has certainly left me feeling that way. I have no objection to paying a fair price for professional work. What I do object to is being encouraged to authorize work that has not been adequately justified, receiving a revised price that raises legitimate questions, and then being repeatedly ignored when I ask for an explanation. My recommendation is simple: Look elsewhere. I cannot recommend this company strongly enough as one to avoid. Their questionable recommendations, unexplained pricing, repeated failures to communicate, disregard for scheduled callbacks, and apparent indifference to a customer facing a legitimate heating problem have been profoundly disappointing. A company that charges professional rates should be expected to deliver professional service, accountability, and communication. In my experience, this company failed on all three counts.

I called Akian plumbing to help me identify a leak. I had already opened up the ceiling of the floor below my bathroom, and they found the toilet flange was deteriorated. They came back in two days to remove the toilet and replace the flange which has resolved the leak. Scheduling was easy with them, and they were great at communicating arrival times and costs before starting the work. Highly recommended.

Absolutely horrible. Repeatedly reschedules due to their own errors and takes multiple trips to fix an issue to drive up their hours. Customer service is terrible and unresponsive after 4:30 and they offer no weekend support. We have been without hot water for over two weeks because of the company but charged over $1000+.

Why Upgrade to a Ductless Mini-Split in Greater Boston?

Ductless mini split technology has revolutionized how we heat and cool Greater Boston homes. If you are currently relying on inefficient window units, noisy portable ACs, or an aging central system that leaves some rooms sweltering, it is time to consider a professional ductless installation. Modern high-efficiency systems offer unmatched precision, allowing you to control the climate of each room individually while drastically cutting your monthly utility costs. Our team specializes in helping you design a custom-zoned solution that provides the most cost-effective long-term comfort for your lifestyle.

Many historic homes throughout Greater Boston lack the structural wall and ceiling clearance needed for central air ducts. Ductless systems bypass ductwork entirely, routing compact, insulated refrigerant line-sets, wiring, and condensate drainage through a neat exterior wall penetration—typically about 3 inches in diameter depending on wall construction (wood siding, plaster, or masonry). This provides an efficient heating and cooling upgrade without tearing down interior walls or sacrificing valuable closet space.

Ductless heat pumps feature advanced variable-speed inverter compressors that modulate heating and cooling output continuously to match demand, avoiding the frequent, energy-heavy on/off cycling of traditional systems. By conditioning only the rooms you actively use, you eliminate the waste of conditioning unoccupied zones. Depending on your home’s insulation and current fuel source (such as electric resistance or oil), inverter systems can substantially reduce seasonal energy costs while qualifying for Mass Save® rebates up to $8,500.

Single-thermostat central systems frequently leave multi-story homes with stubborn hot and cold spots—such as overheating top-floor attics or damp basements. With a multi-zone ductless installation, each room or living area receives its own indoor air handler and independent digital thermostat. Family members can set each zone to their personal preference without fighting over a single central control.

Who Ductless Mini-Split Systems Suit in Greater Boston

  1. Older Homes Without Existing Ductwork: Classic Greater Boston colonials, Victorians, and triple-deckers in Belmont, Newton, Waltham, and Cambridge heated by hot water radiators or steam boilers can add quiet central cooling and supplemental heating without intrusive duct retrofits.

  2. Home Additions, Attics, & Finished Basements: Perfect for bonus rooms, sunrooms, finished basements, and attic conversions where extending existing central HVAC is either physically impractical or would undersize the main system.

  3. Room-by-Room Temperature Zoning: Ideal for households where family members have different comfort preferences or where certain rooms experience severe solar heat gain or winter drafts.

  4. Homeowners Looking to Lower Fuel Costs: Mini-split heat pumps offer a clean, efficient electric heating alternative, allowing homeowners to reduce reliance on expensive fuel oil or propane during shoulder seasons and winter.

  5. Allergy-Conscious Households & Cleaner Air: Traditional ducts accumulate dust, pollen, and pet dander over time. Ductless indoor handlers utilize multi-stage washable filtration, providing cleaner indoor air and linking contextually to our indoor air quality services.

The Ductless Mini-Split Installation Process

Installing a ductless mini-split system is far faster and less intrusive than retrofitting central ductwork, but it still requires meticulous HVAC design and licensed craftsmanship. Here is our step-by-step installation process for Greater Boston homes:

  • 2. System Sizing (Manual J Calculation): We perform precise Manual J heating and cooling load calculations to determine the exact BTU capacity required for each room zone, preventing short-cycling from oversized units or comfort loss from undersized systems.

  • 3. Equipment Options & Room Zones: You select the indoor air handler styles that best suit your interior decor—sleek high-wall units, low-profile floor consoles, or ceiling-recessed cassettes—paired with high-efficiency cold-climate outdoor heat pumps.

  • 4. Professional Installation & Commissioning: Technicians securely mount all units, drill a neat exterior penetration (~3 inches) for insulated refrigerant line-sets and wiring, pull a deep vacuum, test refrigerant pressures, configure digital thermostats, and verify complete system performance.

What Affects Ductless Mini-Split Selection & Cost in Greater Boston

Investing in a ductless mini-split system provides customized comfort and long-term energy savings. Several key factors influence equipment selection and overall installation cost for Greater Boston homes:

  • Number of Zones & Indoor Air Handler Styles: Single-zone systems (one outdoor unit serving one indoor head) start at a lower investment for individual room additions. Multi-zone systems typically support 2 to 5 indoor heads on a single residential outdoor condenser (with multi-split systems capable of supporting up to 8 indoor heads depending on capacity). Indoor styles include high-wall heads, low-profile floor consoles, and ceiling-recessed cassettes.
  • Heating & Cooling Capacity (BTU Sizing): Sizing must accurately match your home's square footage, ceiling heights, window exposure, and insulation quality. An undersized unit will run constantly without keeping up, while an oversized unit causes short-cycling and poor dehumidification.
  • Cold-Climate Heating Performance: Standard heat pumps lose efficiency as temperatures dip below freezing. Cold-climate heat pumps—such as Mitsubishi Hyper-Heating INVERTER®—deliver 100% heating capacity down to 5°F and operate efficiently down to -13°F or -15°F. Equipment engineered for sub-zero performance carries a modest premium but provides reliable primary heating throughout harsh New England winters.
  • Line-Set Distance & Electrical Capacity: The routing length between indoor units and the outdoor condenser, wall construction materials (wood clapboard vs. historic brick or stone), and whether your electrical panel requires a dedicated circuit or 200-amp service upgrade affect overall labor and material costs.
  • 2026 Mass Save® Rebates & Financing: Standard 2026 Mass Save® air-source heat pump rebates offer up to $8,500 ($2,650 per ton) for qualifying whole-home conversions, while partial-home installations receive $1,125 per ton. Income-qualified households may be eligible for up to $16,000 in enhanced incentives. In addition, zero-percent interest financing for up to $25,000 is available via the Mass Save HEAT Loan. Program eligibility, energy assessments, and equipment efficiency standards govern final rebate amounts. Learn more on our Rebates Guide or review official Mass Save Heat Pump Eligibility.

Ductless Mini Split FAQs

Are ductless mini splits effective for heating in Greater Boston winters?

Absolutely. We install high-performance "Cold Climate" heat pumps specifically engineered to provide reliable warmth even when temperatures in Greater Boston drop well below freezing. These systems feature advanced inverter compressors that maintain efficiency and comfort in the toughest Massachusetts winter conditions.

How much can I save with Mass Save® rebates for a mini split installation?

For 2026, qualifying whole-home heat pump installations in Massachusetts can receive up to $8,500 in Mass Save® rebates ($2,650 per ton), while partial-home installations qualify for $1,125 per ton. Income-eligible households may qualify for enhanced funding up to $16,000. In addition, 0% interest financing for up to $25,000 is available through the Mass Save HEAT Loan. Program eligibility, home energy assessment requirements, and qualifying equipment efficiency standards govern final rebate amounts. Akian assists you with required paperwork to maximize your savings. Learn more on our Rebates Guide or check official Mass Save Heat Pump Details.

Can one outdoor unit power multiple indoor air handlers?

Yes. Multi-zone ductless systems allow a single outdoor condenser to power multiple indoor air handlers—typically 2 to 5 indoor units for residential homes, and up to 8 indoor heads on larger capacity multi-split systems. Each indoor unit is individually controlled by its own thermostat, allowing customized temperatures in every bedroom, home office, or living area without conflict.

Does installing a ductless mini-split require demolition or large openings?

No major interior demolition is required. Unlike central ductwork, which requires tearing down drywall ceilings, building soffits, and opening interior walls, ductless systems only require a small exterior penetration—typically about 3 inches in diameter—to route insulated refrigerant lines, power wiring, and condensate drainage. Indoor air handlers mount cleanly on wall brackets or into ceiling joists.

Do ductless mini splits require a lot of maintenance?

Ductless systems are designed for longevity, but they do require simple routine care. Homeowners should clean the reusable air filters every 4–6 weeks to maintain peak indoor air quality. We also recommend an annual professional tune-up to inspect the outdoor condenser, check refrigerant levels, and ensure the condensate drain line is clear for worry-free operation year-round.
