AC maintenance in Lexington, MA typically runs $80 – $200 for a complete tune-up, and most visits can be scheduled within a few days.

We’re Brandt HVAC, part of the Threshold Group family established in 2003. Dispatch and scheduling are coordinated from our Boston office, but our technicians serve Lexington locally. When you book with us, you get a written price before any work starts, and you’ll know exactly who is arriving – name, photo, and background-check verification sent to your phone beforehand. If someone shows up who you weren’t told to expect, that visit is on us. Call (984) 538-9003 to schedule.

Why Brandt HVAC Is Lexington’s Preferred AC Maintenance Company

Lexington homeowners aren’t looking for the cheapest tune-up. They’re looking for someone who won’t scratch the hardwood, who knows a Burnham boiler from a Weil-McLain, and who understands why their 1962 split-level has a Daikin mini-split instead of central air. Our AC Maintenance team has worked the neighborhoods from Follen Heights to Munroe Hill to the streets around Lexington Center. We’ve cleaned condenser coils from closet installs where there’s barely 18 inches of clearance, and we’ve pulled pollen-caked filters from wall cassettes in Capes built during the town’s postwar boom.

Our phones are answered by a live person 24 hours a day, 7 days a week – no automated trees, no callback queues. Every technician arrives in uniform with a photo ID badge, and we send you their name and photo before they leave the shop. The 365-Day Done Right Promise covers every repair: if it fails, we return at no charge. That certainty matters in a town where homeowners often work in biotech, finance, or academia and don’t have patience for vague promises.

HVAC Maintenance in Lexington

HVAC Maintenance in Lexington means something different than in newer Route 128 suburbs with forced-air systems and generous utility closets. Most of the housing stock here – the 1,500 – 2,500 square foot Capes, Colonials, and split-levels built between 1950 and 1975 – was designed around oil-fired hydronic baseboard heat with zero supply ductwork. When our technicians perform HVAC Maintenance here, we’re often maintaining a ductless mini-split system or a closet-mounted air handler that was retrofitted into a space never intended for it. A typical HVAC Maintenance visit in Lexington runs $80 – $200, though homes with multiple mini-split heads or dual-fuel heat-pump setups may fall toward the higher end.

What We Check on Every Visit

We clean evaporator and condenser coils, test capacitors and contactors, verify refrigerant charge by subcooling or superheat, and log blower motor amp draw for trend tracking. In Lexington’s tight installations, we also inspect drain lines for kinks and check that wall cassettes are level so condensate drains properly.

When to Schedule

Book before Memorial Day for cooling-season readiness. Lexington’s summer dew points hit 65 – 70°F regularly, and a system that’s even slightly undercharged will struggle with latent load. For heat-pump homes, we also recommend a pre-winter check in October to verify defrost board function and low-ambient lockout settings.

AC Tune Up in Lexington

AC Tune Up in Lexington is most often a mini-split service call. Because the town’s dominant housing was built without ducts, wall cassettes and compact condensers are the standard, not the exception. An AC Tune Up from Brandt HVAC runs $80 – $200 and includes full coil cleaning, refrigerant verification, electrical testing, and a written report of what we found. We don’t sell you parts you don’t need – our technicians aren’t paid on commission.

Mini-Split Specific Service

Wall cassettes in Lexington’s tight Capes clog fast from spring pollen and cottonwood fluff. Homeowners often mistake weak airflow for a refrigerant leak when it’s actually a dirty evaporator coil. We pull the filters, clean the barrel fan, and check the drain pan. Takes longer than a standard forced-air tune-up, but it’s the only way to do it right.

Closet and Rooftop Condensers

Restricted service clearance is common in these 1950 – 1975 homes. Some companies skip the condenser coil cleaning because it’s awkward. We don’t – we bring the right tools and take the time. A dirty coil or weak capacitor is a cheap catch; a seized compressor is not.

Trusted Brands We Service in Lexington

We maintain all major residential HVAC brands, including Rheem, York, Daikin, and Bryant. For Lexington homeowners, that means we stock common capacitors, contactors, and refrigerant fittings locally, so we’re not ordering parts from a warehouse three states away while your bedroom wall cassette drips condensate onto the rug. We also work on Carrier, Trane, Lennox, Goodman, and American Standard systems. Because so many Lexington retrofits use cold-climate-rated heat pumps, we carry the specialized tools and gauges for R-410A and newer R-32 systems, and our technicians understand the difference between a standard inverter and a Mitsubishi Hyper Heat unit rated to -13°F.

Common AC Maintenance Problems We See in Lexington Homes

• Mini-split cassettes clogged with pollen and cottonwood. Lexington’s mature trees are beautiful, but spring debris packs into wall-head filters and barrel fans fast. Weak airflow and musty smells follow. Homeowners call us thinking they need a refrigerant recharge; usually they need a deep clean.
• Capacitor failure in closet-mounted condensers. These units run hot in tight spaces with poor ventilation. We test run and start capacitors on every visit, because a $15 part prevents a $1,500 compressor replacement.
• Heat-pump changeover never checked. Homes with oil backup and a later-added heat pump often get maintained as “AC only.” Nobody tests the defrost board or low-ambient lockout until the first October night below 35°F, when the system throws a fault code.
• Condensate drain blockages from tight installs. Closet air handlers and wall cassettes with minimal pitch collect algae and sludge. We blow and flush drains as standard, not as an upsell.
