Our Services


When the cold winter weather hits, you need a reliable heating system and a team you can count on to fix it should anything go wrong. Our team offers heating system installation, maintenance and repairs.


You need your air conditioner running optimally to keep you cool during the hot St. Louis summers. Schedule regular maintenance to ensure your air conditioner is in the best shape possible before you run into any issues.

Air Quality

Your home’s air conditioning unit acts as a filter for the air that runs through your home. It traps dust, dirt and pollutants to keep the air quality in your home safe, and can help prevent respiratory problems for you and your family.


In addition to temperature control, you can actually manage the indoor environment of your home at different times of the day and week with your thermostat. Being able to control this can improve your overall energy usage in your home.

Water Heaters

The average shower temperature is 105 degrees Fahrenheit, and, on average, water enters your home at approximately 50 degrees. Your water heater works hard for everything you need it for, and it will eventually wear out—extend the life of your water heater with regular maintenance from Astro Heating and Cooling.


Boilers can be an extremely cost efficient way to keep your home heated, but boiler maintenance and repairs can be tricky. Let the experts at Astro Heating and Cooling help keep your boiler system leak-free and running well.

Get Ongoing Protection with AstroShield

Do you schedule regular maintenance for your home’s heating and cooling systems, or do wait until you have a problem to schedule a repair appointment? If you don’t already schedule routine maintenance checks for your heating and cooling systems, it’s not too late to start! An AstroShield Maintenance Agreement is the safest route you can take when purchasing new equipment through us.

Everyone runs into issues with their heating and cooling systems from time to time, and they tend to surface at the worst possible times for you and your family. Have you ever had your air conditioner give out in the middle of July? Your heating and cooling systems work hard, and no matter what kind of maintenance you run on them, they will give out eventually. 

Invest in an AstroShield Maintenance Agreement: regular check-ups will help maximize the life expectancy of your system and, hopefully, prevent you from running into an emergency. Regular maintenance can also help you save money in the long run. Ensuring your comfort systems are working properly and efficiently can save you money on your bills, and fixing a small issue before it becomes a big problem saves you money for both costs of service and system replacement costs.
