Specializing in new system installs, System replacement, indoor air quality products such as humidifiers, EAC electronic air cleaners, ductless systems (mini splits) & Wi-fi thermostats. Providing both light commercial & residential service in St. Louis! Our #1 priority is your satisfaction!

"I previously worked with another company to replace my furnace. The first company was extremely flakey and would constantly cancel my appointments or simply not show up. Eventually, I decided to go on Angie's List, and I found Siefert Mechanical. This company was extremely quick to get to my house, give me an estimate, and then perform the service. Not only did Siefert Mechanical quote me a price that was $600 less than the first company, they also never cancelled or missed an appointment. They came out once to give me a quote, then the very next time they came out to my house, they replaced my furnace. The quality of their work is extremely professional, and I would HIGHLY recommend this company for any heating/cooling service you need performed."

Heating Oil questions, answered by experts

Your HVAC manufacturer will give you instructions on how often you should service your system. Have your unit professionally serviced at least once a year when in doubt. 

Heat pump systems are different because they provide heating and cooling solutions for your home. In this case, you should have it serviced at least twice a year.

Costs depend on system age, type, labor, and whether part replacements are necessary.

While it's generally safe to stay in a home with a coolant leak if your home is properly ventilated, it's important to have a professional come out to assess the situation right away. You should evacuate your home if you notice any powerful fumes. Additionally, you should leave your home if you are experiencing headaches or dizziness.

Service costs range from $200 to $1,500, depending on maintenance needs, system age, and labor.

Most HVAC companies charge a flat service call fee of between $75 and $150, which includes traveling to your home and inspecting your system to find the underlying problem. Keep in mind that these prices only include diagnostics and the actual repairs will usually be billed separately. If you’re calling for routine service, the service call will be included in your inspection and tune-up, with the total sitting around $150. Your prices could be a little higher if you have a very large home with multiple condensers and air handlers, as inspections and servicing take longer.
