Top Factors That Affect Indoor Air Quality

Having a fresh, clean air to breathe inside homes, offices, and other structures is vital to ensuring the comfort and well-being of people. However, it’s one of the things often neglected, even in commercial settings. Many don’t realize that poor indoor air quality (IAQ) has adverse effects on their health. This can be caused by faulty air conditioning systems and improper ventilation, among other reasons.

4 Benefits of a Well-Maintained HVAC System

As a key component of your home comfort, your HVAC system should always be on top of your maintenance list. After all, it operates around the clock to regulate your indoor temperature. Regardless of what type of system you have, its strenuous activity will cause it to sustain problems over time. That is why it is important to have a professional HVAC technician inspect and evaluate your system regularly. Doing so will pay off in the long run. Read more

5 Items to Add to Your Home for Better IAQ

Most homeowners want to create the healthiest home environment possible for their families. Indoor air quality plays a vital role in keeping your home clean and comfortable. However, sometimes homeowners need a little help maintaining the quality of their indoor air. That’s why we’ve put together this short list of items you can add to your home to improve IAQ:

5 Items for Better Indoor Air Quality

  1. House Plants

Certain house plants can help you purify the air in your home by filtering out volatile organic compounds (VOCs) that are commonly found there. Different plants work to filter out different VOCs. For instance, aloe vera helps clear out formaldehyde and benzene, while the English ivy works to filter out formaldehyde and airborne fecal-matter particles. If you’ve been considering adding a few plants to your home, now may be the time!

  1. Humidifiers

Controlling the humidity in your home is an important part of maintaining a healthy indoor air quality. Humidifiers can help you increase the humidity in your home to an optimal level, which helps prevent certain concentrations of pollutants. Not to mention, it can improve breathing for those who are sensitive to dry air.

  1. Carbon Monoxide Detectors

Did you know that carbon monoxide poisoning claims the lives of more than 400 people each year? That doesn’t even account for those who become ill after being exposed to this dangerous odorless gas. You can protect yourself and your family from exposure to this pollutant by installing carbon monoxide detectors in your home.  

  1. Ultra Violet Lights

Ultra violet lights are another HVAC upgrade that can help you improve the quality of your indoor air. UV lights kill the growth of airborne bacteria, mold, and viruses that can appear in your home, ductwork, and cooling coils. This can help you prevent respiratory issues or other serious illness that results from these contaminants in your home.

  1. Air Purifier

Air purifiers are the ultimate IAQ products as they work to trap and eliminate different pathogens and pollutants that enter your home from the outdoors. Carrier leads the industry in air purifier technology, providing state-of-the-art air purifiers that filter out contaminants in your indoor air to provide a cleaner and healthier home environment.

The Ultimate Los Angeles County Spring Cleaning Checklist

Spring is just around the corner, and many Los Angeles County homeowners have already gotten a head start on their spring cleaning. Though it may seem like a daunting task, a deep cleaning of your home is important to do at least once a year. Not only does this help you stay organized and get rid of things that you don’t need anymore, but cleaning your home can also help you improve your indoor air quality so that you can breathe easier throughout the year. Below, we offer the ultimate checklist for spring cleaning in Los Angeles County.

Los Angeles County Spring Cleaning Checklist

Are you ready to start your spring cleaning? Use the checklist below to make sure that you don’t forget anything important when cleaning your home this spring:

Get all the spring cleaning supplies you need.

Before you start cleaning, take inventory of your cleaning supplies. Make sure that you pick up anything you might need before you get started. The last thing that you want to do is make a trip to the store when you are in the middle of deep cleaning your home. You are much more likely to be successful if you have everything that you need right from the beginning.

Here’s a list of supplies you might need:

  • A good all-purpose cleaner
  • Wood polish for any wood furniture
  • Reusable towels or cloths for dusting and cleaning
  • Vacuum cleaner
  • Clothing that you don’t mind getting dirty

Declutter your home.

Spring cleaning isn’t just about making sure your home is clean. This is also the perfect opportunity to declutter your house. A clean and organized space makes it easier for you to think, relax, and unwind. However, many people tend to hold onto things they don’t need anymore, which can cause quite a bit of clutter in your home.

Here are some ways that you can declutter your home:

  • Go through your closet, and get rid of any clothing that you have not worn in the past 6 months.
  • Round up anything in your garage that you do not need such as sports equipment, tools, or boxes full of old items.
  • If you have any furniture or appliances that you don’t want anymore, call a professional to haul these items away.

You can donate any items that you don’t use anymore to thrift stores or charities. For items that may have resale value, you can put them up for sale in local online forums or hold a garage sale.

Clean your heating and cooling system.

This is a spring cleaning step that many homeowners forget about. Though you may use your heating and cooling system less in the spring when temperatures are more moderate, your HVAC system is in between periods of high use. There is a good chance that you used your heater a lot during the wintertime and that you will use your AC more in the summer. A routine maintenance visit can help you make sure that your system is clean and running optimally before summer gets here.

It’s also important that you stay on top of air filter changes in the spring. Many allergy sufferers may experience discomfort during the springtime when allergens increase. Checking your air filter at least once a month and changing the filter when it becomes dirty or clogged is a good way to keep allergens to a minimum in your home.

Get Your Spring HVAC Tune-Up

Does your heating and cooling system need a spring cleaning? We recommend that homeowners have their HVAC system cleaned and inspected at least once a year. Many Los Angeles county homeowners like to have their service visit in the spring to make sure that everything is clean and running smoothly after using their system all winter. This helps ensure that your system is working efficiently before you start cranking up the AC this summer.

Rancho Cucamonga Air Quality Report

Getting to know the air quality in your city is vital to understanding what air quality issues you may face throughout the year. Though some homeowners may think of air pollution as being a problem outside the home, the truth is that particles and pollutants from outdoor air can make their way into your home and impact your indoor air quality. If you don’t take the right steps to combat these IAQ problems, you may be facing a range of home comfort issues. The key to making sure that the air in your Rancho Cucamonga home is clean and healthy to breathe is understanding air quality issues in the area and taking steps to correct them.

How Air Quality is Measured

There are many different factors that go into measuring a city’s air quality. The United States Environmental Protection Agency uses the National Air Toxics Assessment (NATA) to evaluate toxins in the air across the United States. Using emissions data from 2011, this evaluation method uses models to make estimates about air health risks across different U.S. geographic areas.

The EPA released the most recent update to NATA in December of 2015. This method of measuring air toxins can provide more details than the organization’s previous model, which was based on results from air monitoring stations. The NATA can assess respiratory illness and cancer risk down to the zip code level, making it a helpful assessment for better understanding air quality risks across the United States.

Rancho Cucamonga Air Quality Report

According to the NATA, as of December 2016, the air quality in Rancho Cucamonga, CA is 61.7 on a scale of 100, with 100 being the best. The air quality in this city is better than the national average of 58.4. This rating is based on the number of ozone alert days as well as amounts of seven pollutants including particulates, lead, carbon monoxide, volatile organic chemicals, and sulfur dioxide.

Seasonal changes can significantly impact air quality. In fact, air quality in your city can change day to day. For the latest report on air quality in Rancho Cucamonga, CA, head over to WeatherBug. Each day, the site provides the area’s air quality index (AQI), which tells residents how clean or polluted the air is and what health concerns could be associated with the air quality. The site also provides a list of the area’s major pollutants so that you know exactly what you’re dealing with on a daily basis.

Get Comfortable in Rancho Cucamonga

Pollutants are not the only thing that can impact your indoor air quality and home comfort levels. Factors like humidity, temperature, and airflow can also play a role in how difficult it can be to get comfortable in your home.

Why You Should Choose a Smart Thermostat

Smart technology is changing the way we live, and home comfort is no exception. Smart thermostats make it possible for homeowners to have greater control over temperature and other elements of the home environment such as humidity control or airflow, all from their mobile smart device. If you have not considered a smart thermostat, you may want to learn a little bit more about how this smart device can transform the way you keep your home comfortable for you and your family.

Smart Thermostat Benefits

One of the greatest benefits of the smart thermostat is that it allows you to remotely control your home’s temperature and other home comfort settings. This is great for people with busy schedules who need to be able to turn their thermostat up and down remotely to save energy. For instance, if you are running late coming home from work or extending your vacation, you can make sure that the thermostat is set to an optimal temperature so as not to heat or cool an empty house.

Ultimately, a smart thermostat can help you save more energy over time, which can have a significant impact on your energy costs. Many smart thermostats begin to “learn” your habits, helping you automatically heat and cool your home more efficiently overtime. Being able to adjust the thermostat remotely also helps you have more control over your energy usage. By using your smart thermostat to monitor your energy usage, you can also start to make small changes that help you save more energy overtime. The more efficiently you heat and cool your home, the more money you will save on energy costs year after year.

Carrier® Smart Thermostats

As a factory-authorized dealer of Carrier HVAC products and systems, McLay Services can help you find the right Carrier thermostat to meet your needs and provide expert installation so that you can start reaping the benefits.

What should you expect from an HVAC routine maintenance visit?

Routine maintenance is vital to keeping your heating and cooling systems working efficiently, avoiding costly repairs, and prolonging the life of your equipment. If you are a new homeowner or have just started caring for your own HVAC system, you may be wondering, what exactly does routine maintenance entail?

Some homeowners mistakenly think that changing their air filter is enough to keep their system running efficiently and preventing breakdowns and malfunctions. But the truth is, checking and replacing your air filter is just a small part of heating and cooling system maintenance. Below, we will delve a little deeper into what homeowners can expect from an HVAC routine maintenance visit and how it helps them keep their system running optimally year-round.

What is Involved in Planned Seasonal Maintenance?

If you have not scheduled a seasonal air conditioner or heater tune-up then you may not know exactly what this service entails. Though all HVAC companies may be a little different, McLay offers the following services as part of their routine HVAC maintenance visits:

Performance Furnace Tune-Up

During a Performance Furnace Tune-Up, an experienced HVAC technician will clean the burner assembly, ignition assembly, and blower motor while lubricating any moving parts as necessary. He or she will then inspect the filtration system, flue draft, combustion, vent piping, and humidification system. This tune-up also involves adjusting of the blower components, tightening of the electrical connections, and calibration of the thermostat.

Performance Air Conditioner Tune-Up

During a Performance Air Conditioner Tune-Up, your McLay HVAC tech will clean the condenser coil, condensate drain, and blower motor while adjusting any blower components necessary. The technician will also inspect the evaporator coil, filtration system, and refrigerant leaks. In addition, the tune-up involves testing the condensate pump and starting capabilities, tightening electrical connections, monitoring refrigerant pressure, lubricating moving parts, and measuring air temperature differential, amperage, and voltage.

What to Expect During Your Service Visit

During your service visit, you can expect your McLay HVAC technician to arrive on time and greet you in a warm and friendly manner. As a family owned business, we like to treat our customers like family. Our technicians always serve customers in a courteous and friendly manner as they would their own friends and family.

During your maintenance visit, your HVAC technician will be checking for any issues with your heating and cooling system that may need to be addressed. Our NATE certified HVAC technicians are knowledgeable and trained to recognize any areas of concern during your routine maintenance visit. If they happen to find any issues during your tune-up, they will explain the issue to you and clearly explain what needs to be done. At this time, you can plan your next steps to ensuring that your HVAC system is in working condition. If the HVAC technician finds no issues, you are good to go until your next service visit.

Your AC is Shut Off, and It’s Too Soon for Heat: How to Control Temperatures in Between Summer & Winter


Now that fall is here, you might find yourself not needing to turn on your air conditioner as much as you did in the summer. However, the temperatures are not yet cold enough to warrant the heat. So how do you keep your home environment comfortable when temperatures are in between? You can use the tips below to help you control temperatures in the fall.

Maintaining a Comfortable Home Environment in Fall
What do you do when the weather is not hot enough for air conditioning, but not yet cold enough for heat? Here are some tips for maintaining a comfortable home environment in the fall when you plan on using your air conditioning less.

Adjust temperature on your programmable thermostat.
A programmable thermostat can help you control temperatures when you are not at home, reducing energy waste and saving on electricity costs. Use a programmable thermostat to turn the temperature up when you are not home. Since outdoor temperatures are typically more moderate in fall, it will not take you long to cool your unit back down when you return. This can help you save energy by not keeping your AC running while you are away.

Turn on your fans to keep air circulating in the room.
Fans are not meant to replace your HVAC system as they only circulate the air in the room, not cool it down. However, if you are going to be using your air conditioning unit less given the more moderate climate, it is important to still circulate the air in the room to help regulate temperature, reduce the build-up of allergens, and control moisture.

Improve your insulation.
Proper insulation keeps the temperature in your home consistent while keeping humidity out. Make sure that your home is well-insulated for better temperature control of your indoor environment. Not only will this help you use your HVAC unit less in fall, but it will also help you make your system run more efficiently in winter by preventing heat loss when you use your heater.

Open your windows to let some fresh air in.
If you find yourself enjoying the outdoor temperatures, why not bring a little fresh air into your home? Open up some of your windows to enjoy the breeze. Turning on your fan can help better circulate the air in the room, but make sure that you are monitoring humidity levels and you close your windows before leaving the house.

Make use of drapes or curtains to control heat from the sun.
Even if the temperature outside is comfortable, the heat from the sun can heat up your home environment and cause you to reach for the thermostat. You can help control this heat by using drapes or curtains to keep the sun out. This is a relatively inexpensive way to help regulate temperatures within your home without turning on the AC.

Even if you are using your HVAC system less in the fall, it is still important to continue with regularly scheduled maintenance. If your unit needs a tune-up or you need help getting your system ready for winter, don’t hesitate to give us a call.

The Important Differences Between Humidifiers, Dehumidifiers, and Air Purifiers

Unfortunately, the air inside our homes is not always as comfortable or clean as we would like it to be. Your HVAC system plays a big role in helping keep you and your family healthy and happy. However, sometimes you may need some extra help in controlling humidity levels and filtering out allergens. This simple guide will explain the differences between these three devices and discuss when you should use each to adjust your indoor air quality.

When to Use a Humidifier

Mayo Clinic suggests that ideal indoor humidity is between 30 to 50%. When humidity levels drop below this percentage, the dry air indoors can cause health issues like respiratory distress and dry skin. Low humidity can also cause damage to wooden furniture and cause paper, books, an artwork to warp. A humidifier helps add moisture into the air by emitting water vapor or steam. You can use a stand-alone device to increase humidity in just one room, or add a humidifier as an attachment to your HVAC system to increase moisture levels throughout your home.

Use a humidifier when:

  • Using your heater in winter has caused the air inside your home to feel too dry
  • You are experiencing dry skin, nose, lips, throat, or sinuses
  • Dry indoor air is caused you or your family to have difficulty breathing
  • Dry air has triggered nose bleeds, asthma attacks, or allergy symptoms

When to Use a Dehumidifier

Just as the air in your home can become too dry, it can also become too humid. Increased humidity levels and moisture can also cause health issues. Too much moisture not only impacts the comfortability of your home environment but also provides a perfect breeding ground for mold and other bacteria, which can impact your family’s health. A dehumidifier can help you control humidity levels in your home. This device removes moisture from the air, so that you and your family can relax and breathe easier.

Use a dehumidifier when:

  • Summer has caused humidity levels to increase inside your home
  • The humid air in your home is causing breathing difficulties
  • Humid air has triggered allergies for you or your family
  • You have experienced flooding in your home
  • Your home feels damp or smells musty

Relative Humidity in Los Angeles

Here is a chart for the Los Angeles area (courtesy of

The relative humidity typically ranges from 38% (comfortable) to 90% (very humid) over the course of the year, rarely dropping below 13% (very dry) and reaching as high as 100% (very humid).

The air is driest around December 6, at which time the relative humidity drops below 56% (mildly humid) three days out of four; it is most humid around July 31, exceeding 86% (very humid) three days out of four.

The average daily high (blue) and low (brown) relative humidity with percentile bands (inner bands from 25th to 75th percentile, outer bands from 10th to 90th percentile).

When to Use an Air Purifier

The air purifier does not help adjust humidity levels in your home, but it does help protect you and your family against harmful pollutants. An air purifier traps allergens, chemicals, and other tiny particles that can enter your home from outside, triggering allergies, asthma attacks, and other health issues. This device helps you improve indoor air quality to help keep the air in your home or office clean and healthy.

Use an air purifier when:

  • You or someone in your home suffers from asthma
  • Someone in your household has allergies
  • You or someone in your family is sensitive to chemicals
  • You have pets, which increase the level of dander in your home
