We are a family-owned company with more than 25 years of HVAC experience in our family. We treat every tenant’s home the way we would treat our own, and we give owners an honest opinion on repair versus replacement.
HVAC for Property Managers: The Short Answer
Property managers need an HVAC contractor that responds to tenant calls, follows approval limits, documents every visit and gives honest repair-versus-replace advice. Modern Air Systems works with property managers and landlords across San Antonio on repairs, scheduled maintenance and system replacement for single-family rentals, small multifamily and light commercial buildings.
How We Help Property Managers and Landlords
- AC repair calls for tenant-occupied homes and units
- Spring and fall maintenance for many units on one schedule
- Turnover checks between tenants
- Honest repair-versus-replace recommendations with photos
- System replacement for split systems, heat pumps and packaged units
- Light commercial and rooftop unit service for mixed-use buildings

Clear Communication With Owners and Tenants
We coordinate access with your tenants, keep you updated and send a summary after each visit with what we found, what we fixed and what to plan for. For repairs above an amount you set, we call for approval before starting.
Maintenance Programs for Rental Portfolios
Regular maintenance helps prevent the summer breakdowns that lead to tenant complaints. We can schedule visits across your portfolio, track each system’s age and condition and flag the units that are likely to need replacement soon, so you can budget ahead instead of reacting.
Ask about the Comfort Club maintenance plan for single-family rentals, or a custom agreement for larger portfolios.

Replacement Planning for Older Systems
Many rental homes still run older systems, including some that use R-22 refrigerant, which has not been produced or imported in the U.S. since 2020. We help you decide which units to repair and which to replace, and we can send a same-day price estimate from a photo of the nameplate.

Preventive Maintenance Saves Property Managers Money
Most tenant AC complaints in San Antonio happen during the first hot weeks of the cooling season. A spring tune-up across your portfolio catches weak capacitors, clogged drains and dirty coils before tenants call. The U.S. Department of Energy notes that regular air conditioner maintenance, such as changing filters and keeping coils and drains clean, helps equipment keep performing. Our HVAC maintenance and Comfort Club visits follow a written checklist for every unit.
Turnover Checks Between Tenants
Turnover is the best time to check a system. Between tenants, we inspect the equipment, replace filters, clear drains and note anything that needs attention so the next tenant starts with a working system.
Planning Replacements Across a Portfolio
When several properties have older systems, replacing them on a schedule costs less than replacing them one emergency at a time. We help property managers rank units by age, condition and repair history, and we can give same-day price estimates from nameplate photos. Learn more about HVAC system replacement and AC repair.
Light Commercial and Mixed-Use Buildings
For property managers with retail or office space, we also service rooftop and packaged units. See our light commercial HVAC services.

Ashley WaclawiakGoogle reviewCalled them on Labor Day bc the drain pipe was leaking. They were very responsive in spite of the holiday and were able to get to the property quickly. They were communicative and very easy to work with. They have a full report on the overall health of the system. They’ll go the extra mile for their clients. Highly recommend them
