Our Heating Services in Seguin

When the colder season hits, you want to ensure your home acts as a safe haven from chilly temperatures. When you call on us, we’ll provide you with any of the following services based on what you need:


Some common signs your heater needs repair include a lack of hot air, strange noises, and unusually high utility bills. We specialize in repair services such as changing air filters, checking the circuit breaker and power supply, and calibrating your thermostat, among many others.


There’s a point in time where your heater is simply beyond repair. A few signs it’s better to replace than repair include things like outrageously high repair costs, carbon monoxide emitting from your unit, or a system that’s more than 15 years old. Installing a new heater will result in a more comfortable home and more efficient operation.


Because your system works hard to keep you comfortable, scheduling routine maintenance is essential to keep it running to the best of its ability. It’s ideal to schedule maintenance in the off-season so that your system is ready come winter. Our maintenance services typically include a thorough system cleaning, inspection of parts, and electrical connection tightening.  Regular maintenance will keep your unit more efficient, lower risk for repair and replacement, and improve the indoor air quality.

Expert Cooling Services in Seguin

Texas summers can be blistering, so a cooling system that’s ready to go when you need it is a must. At SM Air, we offer the following services for your convenience:


If you notice things like refrigerant leaks or a lack of cool air, it’s likely time for AC repair. Our team will diagnose the issue, fix it, and test your system to ensure everything is back up and working as it should.


Make sure you’re looking out for signs you need to replace rather than repair your AC unit. If your unit is over 10 years old, you’ve had to schedule a frequent number of repairs recently, or it’s not producing an adequate amount of cool air despite numerous repairs, it’s probably time to schedule a replacement. A new system will work more efficiently and lower the risk of your system not taking care of you on sweltering days.


Regular maintenance will extend the life span of your AC unit and further prevent the need for a repair or replacement. Our maintenance services include inspecting each aspect of your unit–cleaning, tightening, and calibrating it as needed, and we’ll test it afterward to ensure it’s running as it should.
