Indoor Air Quality In San Bernardino, CA

As is common knowledge, outdoor pollution is monitored and screened to help safeguard our general health. Although some business premises have air quality standards, there are none for residential air.

It may seem like a large task, but every homeowner must monitor the total indoor air quality in San Bernardino, as we spend most of our time indoors. Determining what to test for indoor air quality requires understanding what factors influence the air quality in your house.

Numerous contaminants, including minute particles, volatile chemical compounds, viruses, and bacteria, continually contaminate indoor air. Without appropriate ventilation and airflow, variables like changes in relative humidity significantly regulate air quality in your house from day to day.

What Does An Indoor Air Quality Test By Specialists Entail?

Tests of indoor air quality rely on samples collected at home. Numerous airborne pollutants can be located using the findings of these tests, which can be roughly categorized into three groups:

  • Biological contaminants
  • Chemical substances (also known as volatile organic compounds)
  • Pollutants from combustion

What does a test for indoor air quality in San Bernardino reveal? Your findings will assess the substances’ presence and establish whether dangerous pollution levels exist in your home.

How To Determine Whether Indoor Air Quality Testing Should Be Performed?

How can you tell if your home needs indoor air quality testing? Let’s examine 3 observations to consider:

  • Sight: You can spot water damage, wall or ceiling stains, or unusual dust.
  • Smell: You detect strange, lingering scents.
  • Health issues that seem to be limited to your house: Symptoms such as skin rashes, headaches, nausea, and eye and respiratory discomfort.

When To Schedule Indoor Air Quality Testing?

There is never a “bad” moment to test your indoor air quality, but if you have any of the problems mentioned above, it may be due to poor indoor air quality in San Bernardino. An excellent strategy to identify the air quality issues in your house is to get an inspection from our indoor air quality specialist.

Our expert will visit your residence, observe, and decide whether further testing is required. They can then carry out the required tests and offer suggestions for corrective action. Additional DIY testing kits are available but don’t offer the same detail as a professional test.

What Steps Can You Take To Improve The Air Quality In Your House In The Meantime?

A smart place to start is by investing in an in-room air purifier with a HEPA and carbon filter to eliminate particles and pollutants. You can also improve ventilation by opening windows and doors to release toxins that have accumulated within.

Our A/C went out on Labor Day; we called 4 Points AC and Heating. They sent someone out right away even though it was a holiday. The technician was very friendly and knowledgeable; he gave us a quick diagnosis. He sat down with us to give us a few options. We decided to replace our AC and Heating unit. They even waived our service call fee! Their team was so professional and courteous; they went above and beyond for us. We highly recommend 4 Points for their hard work and skill! Our new system works great!!  

Stephanie B.

AC went out at 6pm the day before. They showed up on time and offered several options for repair and explained the warranty. Quick and responsive. Thank you would use them again.  

Chris A.

Esther R.

Living in the inland empire gets quite hot! Today our AC unit went out and we decided to give 4 Points AC a call. They sent a technician out by the name of Antonio the same day. He was able to get our AC unit up and running. Our AC unit needed parts replaced because the prior parts were damaged. He was able to go pick up the parts and come back and repair. His service was above and beyond and now our AC is up and running! Thank you Antonio for your exceptional customer service. We are very happy customers! We will definitely be using 4 Points AC for all of our AC services.  

Bill L.

Outstanding customer service! They notify prior to arrival and send a message with the technician’s picture. Office staff and field staff are highly professional. This company would be perfect if their prices were less.

I recommend 4 points AC and heating to anyone that doesn’t want to bother with their HVAC. These guys service all my units, and since I have a service contract with them, if I have a problem they show up the same day or the next. Just yesterday I reported a problem with one of my units, they showed up a couple of hours later and told me I needed a part replaced. Since I have a contract with them they gave me a discount price, in total, the price was very reasonable. I travel for work and the fact that I know that if something happens I don’t have to worry about my house getting to 100 degrees. I don’t think I’ll ever change companies as long as I’m in the IE. Thanks, Daniel, Elizabeth, and the rest of the 4 Points team.
