"System installed 2 years ago. Tore out of wall. They advertise 24/7 emergency repair. Called for help after trying to fix it for an hour so I could at-least get my car out of the garage. This was a Sunday. Traveling home for holidays on Monday. Texted with Cory for some advice. Which didn’t work then he called me to try to help. Obviously at this time I was getting frustrated and panicked. Asked for someone to please come help me. And he said they don’t work on weekends and I was demanding. Definitely do not recommend"

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 and Air Conditioning questions, answered by experts

ACs don't run on water. They're not connected to drain pipes or any part of your plumbing system. However, they need refrigerant to run. Refrigerant is a gas or liquid that has a low boiling point and absorbs the heat in your home. ACs need this in order to be functional and cool your home. If you suspect your AC is low on refrigerant, you need to contact a licensed HVAC professional. Refrigerant is a dangerous chemical that requires specialized training and permits to work with. 

Some of the signs of HVAC issues include rising energy bills, rooms not cooling or heating properly, loud noises when in operation, and signs of condensation. To illustrate, if you’re wondering how to stop condensation on air vents, you’ll need to have your HVAC inspected. 

Yes, AC coil cleaning is definitely worth it. Cleaning your AC coils ensures your AC unit will function efficiently for the long term. Dirty and grimy AC coils make your unit work harder to cool your home, resulting in higher electric bills. Additionally, having your coils professionally cleaned regularly will reduce the possibility of extensive maintenance and repair costs.

The cost to add Freon to an AC ranges from $100 to $350. It can increase up to $600 for large AC units requiring much more coolant. The cost also depends on how much refrigerant your unit needs. If only a small amount of Freon leaked out, your cost would be on the lower side. A complete replacement of all the required refrigerant can get expensive.

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.
