Does your air conditioning syste­m sometimes blow hot air instead of cool? Or pe­rhaps it makes strange noises. You might wonde­r, "What's wrong with my HVAC?" The answer is often that some­ parts need to be che­cked regularly. Let's look at which parts re­quire attention and how often you should che­ck them to keep your syste­m running well. Key Parts of Your AC Unit to Che­ck On The Regular Air Filters Air filters ke­ep your indoor air clean. They stop dust and dirt from ge­tting inside. But you need to che­ck them often. How often: Look at the­m once a month. Change them e­very 1-3 months. Why it matters: Dirty filters block airflow. This make­s your AC work harder and costs you more money. The­ Outdoor Unit The condensing air unit removes hot air from inside­ your home. But it can get dirty or blocked by le­aves and sticks. How often: Check it e­very 3 months. Why it matters: Kee­ping it clean helps it run bette­r and last longer. The Indoor Coils The indoor coi...

When something goes wrong in a condenser, most business owners make it their top priority to fix the issue. This is because condensers carry essential raw materials and finished products, damage to which can directly result in financial loss. In today's blog, we are discussing one of the most important components of the outdoor condensing unit, the ‘Chiller’. Knowing in detail about this art will help you make decisions about replacing your condensing unit and using lifestyle changes. Here's What Chillers Do in Outdoor Condensing Systems Do you use a condensing unit daily? If so, here is all you need to know about chillers. Function of Chillers in Cooling Systems Fit inside a condensing unit, a chiller looks like a big box with coils and pipes inside.  It consists of several electronic parts, majorly including a compressor that compresses the cold gas; and a fan that blows air over the coils. It also has pipes to carry the cold gas around, keeping everything inside nice and co...

AC coupling lets only changing signals through, blocking steady ones. It's like focusing on waves in the ocean but ignoring the overall water level. DC coupling lets both steady and changing signals through. It's like looking at the ocean waves and the overall water level. In case you have been wondering what difference AC and DC Coupling make to your Air Conditioning or Refrigeration, this blog might just give you the answers to your questions. 3 Key Differences Between AC and DC Coupling  Working Principle So what is a coupling? A coupling is a mechanical device connecting two parts or objects like shafts. The first point of difference is the concept behind their functioning. In AC coupling there exists a Capacitor that blocks the incoming DC signal, i.e. AC coupling only accepts the AC signal and removes the DC offset, whereas in DC coupling the capacitor is absent which allows both DC and AC signals to pass. How Flexible Are They for Your System? HVAC units are often seen ...
