Call (984) 538-9003

We’re familiar with the particular HVAC landscape here, the one shaped by forces no neighboring town experienced at the same scale. After the Columbia Gas explosions in September 2018, thousands of Andover homes lost natural gas overnight. The emergency conversions that followed, many done under extreme time pressure without full commissioning, mean a lot of equipment installed in 2018 and 2019 is now reaching its first critical service cycle. That’s not abstract history for us. It’s the context we work in every time we pull onto Main Street or head up toward Shawsheen. Our AC Maintenance team knows how to verify whether a heat pump or propane-converted system was ever properly charged, airflow-balanced, and documented. And we know that in Andover’s larger Colonials and Capes, with their multi-zone layouts and finished basements, a flat-capacity single-stage system often struggles against the latent humidity that builds through July and August.

When you call (984) 538-9003, a live person answers. No automated tree, no callback queue. We’ll give you a written price before any work starts, and you’ll know exactly who is coming to your door, by name and photo, verified through our Threshold Standard.

Why Brandt HVAC Is Andover’s Preferred AC Maintenance Company

We’ve built our reputation in Andover on being the company that tells you precisely who is walking through your door before they arrive. Every technician is background-checked, identity-verified, and introduced to you by name and photo. At your door, they show a photo ID badge. If anyone arrives who you weren’t told to expect, that visit is on us and we make it right. That matters here, where many homeowners are parents with young children or older residents living alone, and opening the door to a stranger carries real weight.

Our response time to Andover is typically same-week for maintenance calls, with scheduling coordinated from our Boston office to keep routes efficient through the Merrimack Valley. We know the local housing stock, the 1960s-through-1990s subdivisions off Route 28, the newer luxury builds near Haggetts Pond, and the specific challenges cold-air drainage from the surrounding hills creates for heating and cooling loads. That local knowledge means we don’t waste your time with guesses.

Every repair we make carries a written guarantee, and our 365-Day Done Right Promise means if it’s not done right, we return at no charge to make it right. No argument, no additional fee.

HVAC Maintenance in Andover

HVAC Maintenance in Andover requires understanding the dual demands of Merrimack Valley winters and humid summers, especially in the larger homes common here where multi-zone systems are typical rather than exceptional. The job involves a complete inspection, cleaning, and calibration of your heating and cooling equipment, checking refrigerant charge, testing electrical connections, measuring airflow, and identifying wear before it becomes a breakdown. For Andover homeowners, we recommend scheduling this annually, ideally in spring before the cooling season peaks, though fall appointments work well for heat-pump systems that handle both heating and cooling. A typical HVAC maintenance visit in Andover runs $80 – $200.

What We Check on Every Visit

We inspect the condenser coils, evaporator, blower motor, and electrical connections. We measure refrigerant levels by weight, not guesswork, and verify that your system’s airflow matches the manufacturer’s specification. For the heat pumps and propane conversions common in post-2018 Andover installations, we specifically check whether the original commissioning documentation exists and whether the refrigerant charge has ever been verified since installation.

Documentation You Receive

After every maintenance visit, you get a written report of what we found, what we adjusted, and what to monitor. If we identify a developing issue, we explain it in plain language with a written price for any recommended repair. No work proceeds without your written approval.

AC Tune Up in Andover

AC Tune Up in Andover is the cooling-specific subset of full HVAC maintenance, focused on preparing your air conditioner or heat pump for the heavy workload of June through September. The work includes deep-cleaning the outdoor condenser coils, checking the indoor evaporator for mold or restriction, testing the capacitor and contactor, measuring temperature drop across the coil, and verifying that your thermostat accurately commands the system. Given Andover’s humidity, we pay particular attention to whether your system is properly dehumidifying, not just cooling. A typical AC tune-up in Andover costs $80 – $200.

Humidity and Latent Load

Andover summers bring real latent cooling loads, the moisture your system must remove to keep the house comfortable, not merely cool. Single-stage systems in oversized homes often short-cycle, cooling the air too quickly without running long enough to dehumidify. During your tune-up, we measure whether your system is achieving proper humidity reduction and advise if adjustments or equipment changes would help.

Post-Explosion System Verification

For the many Andover homes with heat pumps or converted systems installed during the 2018 emergency, we specifically verify refrigerant charge against factory specs, check electrical connections that may have been rushed, and confirm airflow settings appropriate to your home’s ductwork. These systems are now 6 to 7 years old and entering their first major service cycle.

Trusted Brands We Service in Andover

We maintain and repair all major residential HVAC brands, including Rheem, York, Daikin, and Bryant, and we stock common parts locally to minimize wait times for Andover homeowners. Whether your system is a York heat pump installed during the post-2018 conversions, a Daikin mini-split handling a finished basement off Route 28, or a Rheem central air unit cooling a Shawsheen Colonial, our technicians arrive with the components and factory specifications to service it properly. Fast turnaround matters in July when humidity is high and the house won’t cool. We coordinate parts through our Boston office and regional supply chain to keep Andover calls moving without multi-day delays.

Common AC Maintenance Problems We See in Andover Homes

• Refrigerant undercharge from unverified 2018-2019 installations. Many emergency conversions after the Columbia Gas explosions were commissioned without proper charging documentation, and we regularly find heat pumps running 10-15% low on refrigerant, killing efficiency and compressor life.
• Airflow mismatch in multi-zone Colonials and Capes. Andover’s large homes with finished basements and multiple stories often have dampers and zone controls that were never properly balanced, leaving upper floors hot and basements clammy while the thermostat reads satisfied.
• Condenser coil fouling from cottonwood and pollen. The mature trees throughout Andover’s established neighborhoods shed debris that clogs outdoor coils by mid-June, raising head pressure and reducing cooling capacity exactly when demand peaks.
• Capacitor degradation from voltage fluctuation. Summer grid load in the Merrimack Valley can create voltage sag and spike patterns that stress start capacitors, a common midsummer failure we catch during preventive tune-ups before you’re left without cooling.
