Systems to Improve Your Indoor Air Quality

Indoor air quality is just as important as the temperature of the air in your home or office. Breathing in poor air can impact health conditions like allergies, respiratory disorders, and headaches.  Our air filtration systems, humidifiers and dehumidifiers help improve the quality of your indoor air at your residence or place of work in Hamilton, Burlington and Oakville.

The Importance of Clean Indoor Air

You spend most of your time indoors, so the air in your home should be fresh, clean and free of dust, mould, pollen, pet dander and other contaminants. Your home’s Indoor Air Quality, or IAQ, is the measurement to determine the quality of your home’s indoor air and is comprised of several different factors: temperature, humidity, air purity and air freshness. If one of these factors is lacking, then it can lead to poor IAQ. At Lancaster, we offer a wide range of air quality systems and solutions that can make a significant difference to the well-being of your family, friends and co-workers, especially for individuals with respiratory issues.

Since inventing the first residential humidifier in 1954, AprilAire has continued to provide the best products for clean, healthy, indoor air for our customers.

   Air Purifiers

If any member of your family has respiratory concerns, cleansing the air in your home can help alleviate some problems by filtering and eliminating harmful elements in the air you’re breathing.  Our state-of-the-art air purifier systems trap and kill bacteria, viruses, mould spores, allergens and other pollutants in the conditioned air and keep them out of the air your family breathes.


No one likes too much humidity or too little humidity.  To help keep your home at a comfortable level, we offer a variety of humidifier products.  Our steam humidifiers are great when a high degree of humidity control is desired, or you could choose a fan-powered or bypass humidifier.  All work in tandem with your furnace or fan coil and operate quietly with little energy.


Managing indoor humidity is important to creating a comfortable, healthy indoor environment.  Too much humidity can encourage mould growth and create a cozy home for dust mites and other pests to thrive.  Dehumidifiers are a great tool in our repertoire to fight specific and unique comfort issues.  Sometimes, all that’s needed is a simple solution to remedy those pesky problems and help keep your home cool.


Air is like bread, it shouldn’t be stale.  Our innovative ventilators are designed to remove stale air from your home while keeping valuable energy from escaping.  Not only do all of our ventilators work quietly and efficiently to bring fresh air into your home all year long, but they also pre-condition the incoming air to better match the inside air temperature before it enters your ducts.

   Clean Ductwork

To have clean air, the ducts in your home or workplace must be clean. Whether installing new ductwork or repairing or cleaning your ducts, Lancaster’s Duct Cleaning service ensures your ductwork is clean and sanitized.

Indoor Air Quality FAQs

I have an issue with my “Lancaster” dehumidifier…

We often receive questions and requests regarding these “Lancaster” branded dehumidifiers. Lancaster Heating and Cooling does not manufacture, sell or service these products. We recommend contacting your retailer or manufacturer directly with any questions regarding these dehumidifiers.

Do electronic air cleaners really work? 

Electronic air cleaners can greatly improve home air quality and comfort levels. If you suffer from allergies or have pets, they’re a must. Some electronic air cleaners can remove dust particles and pollen as small as .10 microns. Horizon Services offers a variety of air filtration devices. 

What is the ideal indoor humidity level? 

The American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE) recommends a household humidity level between 30 and 60 percent. 

How can I detect carbon monoxide in my home? 

The best method of detection is to use a carbon monoxide detector in your home.  A carbon monoxide detector is a device very similar to a smoke alarm.  It monitors the air for carbon monoxide and sounds an alarm if a specific level is detected.  Ideally, you should have one detector adjacent to every living area in your home.  Carbon monoxide detectors are most effective when used in combination with preventative maintenance. 

How often should I be changing my furnace filter? 

There are many variables regarding furnace filters.  For example: What type of furnace filter are you using?  Do you run your fan continuously?  Do you have shedding pets?  Have you had any renovations or construction done lately?  Since the filter is the best protection for your furnace, our advice is to buy a good filter and check it regularly.
