24-Hour Emergency AC Services

If something is wrong with your HVAC system, you need a team that can help you as quickly as possible. It is not exactly a secret that it can get hot in St. Louis during the summer. It can be downright dangerous if you have to go without air conditioning for an extended amount of time. Even though we certainly provide services during normal business hours, we are proud to provide St Louis AC repair 24 hours per day, seven days per week. If you are looking for emergency air conditioning repair when your HVAC system fails, call Welsch Heating and Cooling right away.



Signs You Need Emergency AC Repair Services

There are several signs that might indicate you need emergency AC repair services. They include:

Air Isn’t Coming From The System

If you don’t have any air coming from your air conditioners at all, this is a sign that something is wrong with your cooling system.  We will figure out what is going on and restore cool airflow. There are a number of potential reasons this is happening. One thing you can do to try to troubleshoot this issue yourself is by changing out your air filter if it’s been a long time since it’s been replaced. This may help restore airflow to the system. 

System Is Frozen

If your system is frozen, this is a sign that you need to reach out to for 24-hour emergency HVAC service. Perhaps you are hearing strange noises, or maybe the system simply won’t respond to your commands. A member of our HVAC emergency service team will get your air conditioner working properly again. 

System Is Constantly Short Cycling

Short cycling takes place when your system constantly turns on and off again without finishing the job. This is one of the most common problems we deal with, and we have the equipment to solve this quickly. Our emergency service technicians in the St. Louis area can handle this job, and we will get your AC unit functioning properly again. 

Poor Indoor Air Quality

If you are noticing poor indoor air quality, do not wait to fix this problem. Our technicians can provide you with the solution you need. Large quantities of dust, bad odors, and high humidity can make the inside of your home very uncomfortable. You don’t have to tolerate these issues, and repairs to your ac system may solve these problems. 

Warm Air Is Coming From the System

If you notice that warm air is coming from your system, you need our professional, knowledgeable team to help you. Perhaps there is a refrigerant leak, or maybe there is a problem with the air filter. We will let you know exactly what we need to do to fix this problem.
