Mitsubishi Electric HVAC systems & service

For most NYC homes, we recommend checking your HVAC filter every 30 days and replacing it every 1-3 months, depending on the filter type and your living conditions. Standard 1-inch fiberglass or pleated filters typically need monthly replacement, while higher-MERV pleated filters (MERV 8-13) can last up to 90 days. You should change filters more frequently – every 3-4 weeks – if you have pets, run your system heavily during Brooklyn summers or Manhattan winters, live near construction, or suffer from allergies. A clogged filter restricts airflow, forces your blower motor to work harder, spikes energy bills, and shortens the lifespan of your compressor. Good news: filter swaps are a DIY job – no technician required. If you’re unsure which MERV rating fits your system, we’re happy to advise during your next service visit.

At minimum, your HVAC system should be professionally serviced once per year – ideally twice for central air and heat pump systems. In New York, the smart schedule is a spring tune-up before cooling season (April-May) and a fall inspection before heating season (September-October). During a full tune-up, our licensed technicians check refrigerant charge and pressures, inspect electrical connections, clean the condenser and evaporator coils, test blower performance, measure airflow, verify thermostat calibration, and look for early signs of moisture, mold, or refrigerant leaks. Mini-split systems installed in Brooklyn brownstones, Manhattan condos, or Queens multi-family homes especially benefit from annual deep cleaning – coastal humidity and NYC dust accelerate buildup on coils and blower wheels. Regular maintenance doesn’t just prevent expensive breakdowns in July heat waves or January cold snaps – it protects your manufacturer’s warranty and can extend system life by 5-10 years.

We keep billing simple and transparent for every client across NYC and Long Island. Prime Air Group accepts cash, Zelle, personal and business checks, and wire transfers. For commercial clients, property managers, and multi-unit residential buildings in Manhattan, Brooklyn, and Queens, we offer invoicing with standard net terms on approved accounts. Every job – whether a single mini-split repair or a full central air installation – comes with a written estimate and an itemized invoice, so you always know exactly what you’re paying for. No hidden fees, no surprise charges after the work begins. If you have questions about payment timing, progress billing on larger installs, or documentation for co-op board approvals, just ask when we schedule your visit.

Plan for about one hour on-site, though timing depends on the scope of work. A straightforward mini-split replacement in a Brooklyn apartment may take 30-45 minutes, while a full central air install in a Manhattan townhouse or a commercial HVAC project in Queens can run 90 minutes or more. During the visit, our estimator measures the space, reviews existing ductwork and electrical capacity, performs load calculations, assesses access and line-set routing, and walks through your comfort priorities. To keep things moving, we strongly recommend that all decision-makers be present – homeowners, spouses, landlords, or property managers – so we can answer questions in real time, confirm equipment placement, and finalize scope without follow-up delays. For co-op and condo owners, we can also prepare documentation your building may require for work permits or board approval.
