Our Heating Services

When winter hits Schertz and brings chilly temperatures, you want your heater to keep your home warm and cozy. Because of this, we specialize in the following:


Keep an eye out for signs like a lack of hot air, strange noises, unusually high utility bills, and the age of your unit, as all of these factors may play into the need for repair. We offer repair services in the form of changing air filters, checking the circuit breaker and power supply, and calibrating your thermostat, among an array of other things you may need to get your heating system up and running again.


At some point or another, your heater will get to be beyond repair. Some common signs it’s better to replace than repair your heater include abnormally high repair costs, the emission of carbon monoxide, or the age of your unit — if it’s over 15 years old, it’s probably time for an upgrade. Replacing your heating system will keep your home comfortable and lead to better energy efficiency.


Scheduling routine maintenance is essential to keep your heater running at full capacity. It’s best to schedule maintenance in the summer so that your system is ready to go when the colder weather hits. Our maintenance services usually consist of a thorough system cleaning, parts inspection, and electrical connection tightening. Regular maintenance will keep your unit more efficient, at a lower risk for repair and replacement, and will also improve the indoor air quality.

Expert Cooling Services in Schertz

Texas summers are known to be quite hot, making it crucial to ensure your cooling system is ready to keep up with your demanding needs. The qualified contractors at SM Air offer the following comprehensive services:


Signs that hint at the need for AC repair include things like refrigerant leaks or a lack of cool air. Our team will be there to diagnose the issue, correct it, and further test your system to make sure everything checks out accordingly.


It’s important to keep an eye out for signs you need to replace your AC unit rather than repair it. If it’s over 10 years old, undergone a frequent number of repairs recently, or it’s constantly not producing an adequate amount of cool air, it’s probably time to schedule a replacement. A new system will increase energy efficiency and lower the risk of your system not taking care of you on sweltering days.


To extend the life span of your AC unit and prevent the need for a repair or replacement, our maintenance services are in place for your convenience. These services include inspecting each aspect of your unit and cleaning, tightening, and calibrating it as needed, and it’ll also be tested afterward to ensure it’s running as it should.

Emergency HVAC Service

Weather can be finicky and unpredictable, just like the machines we rely on to keep us safe and cozy when temperatures fluctuate. Unfortunately, your HVAC unit can run into issues when you’re unprepared and unsuspecting — even in the middle of the night when you’re sound asleep. At SM Air, we offer 24/7 emergency HVAC services for that very reason.
