Our company delivers top-quality products to popular brands all around India. You can look through our list of clients to understand the efficiency and quality delivered throughout the years. We pride ourselves on being the best HVAC system manufacturer in India as we expand to other countries as well.

We often worry about the air quality outdoors and choose to wear masks. However, the indoor air can be just as polluted with no way to be recycled. With a high-quality HVAC system in place, you can keep your indoor air quality in check.

HVAC systems tend to fade away with time in terms of efficiency. If your system is older than 15 years, it should be replaced soon to ensure efficiency and better temperature maintenance. Sticking to the old systems could lead to higher energy bills and inefficient temperature maintenance.

To get information related to the HVAC product pricing at Envigaurd, you can get in touch with us at contact@envigaurd.com or give us a quick call at 8147605843. 

While most HVAC systems do not need servicing every now and then, it is important to opt for an Annual Maintenance Service to ensure any abrupt error or damage is corrected with ease.

As per HVAC standards, it is recommended that you opt for air filters that have MERV 6 or a higher marking. Residential systems can do well with MERV 8 to 13 filters, while industries would do well with MERV 14 or higher.

HVAC air filters should typically be replaced every 30 to 60 days depending on the usage. The duration can be longer for commercial-grade filters depending on the usage.

If you are looking for signs to replace your HVAC system, here are a few you need to keep in mind:

  • Your HVAC is 15 years or older
  • Repair cost is higher than half the original cost of the system
  • Ever-increasing energy bills
  • Temperature doesn’t stay; it keeps fluctuating
  • Machine emitting odd sounds
  • Unusual smell from the system
  • High amount of dust throughout the house
  • Poor-quality air with higher chances of allergies
