Home Air Quality & Your Allergies

If you suffer from allergies, the last thing you want is your home’s air quality to be less-than-stellar, as it might result in your allergy symptoms being even worse. When we think of polluted air, we likely think of contaminated outdoor air. However, according to the Environmental Protection Agency (EPA), indoor air quality is often even more polluted than outside air. Some things that may affect indoor air quality include allergens, outdoor air pollution that makes its way inside, and scents, chemicals and volatile organic compounds (VOCs).

Startling Statistics

Don’t underestimate the importance of high indoor air quality. The EPA estimates that indoor air pollution ranks amongst the top five environmental risks to public health. Over 15 million Americans have asthma and this number has increased by almost 50 percent in the past 30 years. Children breathe at a faster rate than adults, so they are at an increased risk of developing problems from poor air quality. In fact, they inhale more than 50 percent more air per body weight than adults.

Where Do Allergens Exist?

As they’re invisible to the eye, allergens exist in the most unsuspecting places, including in the fabric of your furniture, carpets, bedding, furniture, curtains, pillows, among clutter, and many other places. Mold is also a factor that comes into play when considering air quality. It usually forms around damp places such as near sinks, showers, basements, humid areas or on produce. Keep mold at bay to ensure it doesn’t send damaging chemicals into the air for you and your family to inhale.

Invest in an Air Purifier

At Deljo Heating, Cooling & Plumbing, we offer Carrier’s award-winning Infinity Air Purifier GAPA. This machine is silent and works in conjunction with your air conditioner to help improve your air quality. Its unique capture-and-kill technology traps up to 95 percent of pathogens, shrinks them in size down to .30 microns, and uses an electrical charge to kill them.

This was my first time as a Deljo customer, and I was very pleased. My technician, Giovanni, was very thorough and diligent. He serviced my furnace and identified a faulty sensor that was causing the unit to shut itself down. Deljo ordered the part, and Giovanni replaced it a few days later. Overall, the team at Deljo was great. The dispatcher kept me informed about Giovanni’s arrival time, and the supervisor assisted Giovanni when he was diagnosing the problem with the furnace. I highly recommend Deljo.

I’ve used Deljo for over 10 years now and they always do a good job. Izzy was the technician for this visit and he did an excellent job with my winter maintenance on my multiple units in the household. He also addressed an issue while cleaning the furnace blower wheel. His communication was clear and concise with what he planned to do to address the issue quickly. He was confident and I had 0 concerns or questions. Great job Izzy!

Paul was great! Arrived on time and completed maintenance on my humidifier, tankless water heater, and two furnaces. All work was performed under my Gold Star maintenance program, so all maintenance charges were covered. Paul did provide a few proposals for additional services on furnace & tankless water heater, but those were emailed to me for further consideration. Paul was friendly, knowledgeable, and answered all my questions.

Gabe did an excellent job with our annual service visit. He arrived in the early part of our service window, was friendly and knowledgeable, and got the work done in a very reasonable amount of time. I have great confidence in Deljo, and am a long-time customer.

I’ve been using Deljo for 20 years for HVAC but now venture into enlisting their plumbing services. Bashar was very courteous, efficient & informative, and I’d definitely request him again for the next plumbing job. Great experience!

Working with Deljo is always a good experience, and today’s appointment with Izzy was no different. He was able to come early which actually worked better with our schedules, but called me ahead of time to make sure that was okay. He was friendly and knowledgeable when he explained the work he had done during his visit and our options for fixes. He was also able to schedule a quote appointment for us while he was still here. We would highly recommend working with Izzy and the Deljo team!

Drew performed the seasonal maintenance on my AC. It needed some repairs and updates and he was able to fix everything at the same appointment. He also noticed issues with the hot water heater and we were able to get ahead of that, as well.

I would leave six out of five stars if I could! My technician Jorge went above and beyond on his service. There was buildup in the rental property’s toilet from the previous tenant. One maintenance person did a surface level job of cleaning but did not fully remove the obstruction. Jorge went above and beyond and came to a solution and even explained the perpetual problems older toilet models can cause. Moving forward with this insight, I can perform my own upkeep the previous tenant did not. Thank you kindly!

We just had our new boiler installed by Jonathan and Carlos. First rate work! They arrived on time, removed the old boiler, installed the new unit, and explained the features. Both guys were pleasant. Bring on the cold this winter! We are ready thanks to the team from Deljo.
