Upgrade Your Heating System

How do you know when it’s time to consider upgrading to a new heating system? Obviously if the unit has died or is not working, but it may be wise to consider replacement well before that happens or before costly repairs add up. Many things can greatly affect the longevity and efficiency of your furnace, heat pump or boiler system over the years such as not changing the air filters often enough or not having regular maintenance to ensure proper operation. Additionally, a poorly operating heating unit can negatively impact the air quality in your home.

Healthy HVAC Add Ons

Consider an HVAC Add On for greatly improved health and comfort benefits. Make sure your home is safe, healthy and comfortable easily and affordably with these whole home HVAC Add on technologies. Air in your home becomes continually contaminated by dirt, germs, debris, odors. Healthy, clean air in your home is healthier and more comfortable for you and is achievable.

Inverter Technology

Inverter HVAC systems offer many benefits to homeowners such as:
Higher Efficiency
Greater Energy Savings
More Uniform temperatures in your home
Quieter operation
This latest HVAC technology has been developing over the past several years and has been utilized in Ductless Mini Split applications. Now offered by many manufacturers for whole home ducted systems as a means to improve performance and efficiency.

Coil Care

Coil care for your HVAC system is very important. A coil is a main component of your HVAC System. There is a condenser coil and an evaporator coil. These coils are an integral part of the heat exchange that happens when cooling your air. These coils contain your refrigerant. Many older systems used Freon (R22) while more recent systems use Puron (R410a).

Attic Ventilation Fans

The benefits of an attic ventilation fan are more cumulative rather than instantaneous. An attic fan operates as an exhaust and will work to push hot air out of the attic through a shuttered or louvered vent. As heat continually rises, the attic fan will help eliminate accumulating heat.
As the heat is evacuated, moisture and odors can also be reduced.

Smart Thermostats

Smart thermostats have entered our world and are designed to work and integrate into our smart homes with smart devices. These thermostats can be controlled locally or remotely with smartphones, computers, smart systems like Google or Alexa. Those that love automation will love these features. Some models also will “learn” your needs and can make adjustments on their own.

Odors and Allergens

Many things cause odors and allergens in your home. We generally differentiate between odors and scents. Both refer to things we “smell”. Odors generally refer to smells which we find objectionable, while scents we find pleasurable. There are organic odors and inorganic odors. Both organic and inorganic odors come from molecules which become airborne and allow us to interact with them.
Allergens we cannot see or smell, but they can cause significant health issues especially if you have allergies.

How HVAC System Manages Airflow

Your HVAC System is a system that manages airflow in your home. To simplify the operation, the system takes in air, warms or cools it and then redistributes it around your home to maintain the desired temperature. Of course, there is much more to it. As the air is brought into the system, it is filtered to remove contaminants and debris.
Residential HVAC systems require unobstructed airflow in order to operate properly.

Ductless, Mini Split AC

Ductless Air Conditioning systems are well worth considering in certain circumstances. Central Air systems operate by sending air through ductwork. The ducts are installed to direct the flow of air through tubes called ducts.

Plants Improve Indoor Air Quality

Believe it or not, house plants can help improve the air quality in your home. Plants have a natural ability to purify our air. Their process of photosynthesis enables them to absorb light, and gasses such as carbon dioxide and use them to fuel their growth. As a bi-product they produce oxygen.

Indoor Air Purification

The Reme-Halo air purification system is a new warrior in the fight against contaminants in your home. This device is a “Whole Home” purification system. It is installed right in your HVAC duct system, and kills bacteria and viruses in the air as well as on surfaces. It also combats allergens, smoke, odors and VOCs (Volatile Organic Compounds) in homes and businesses.

Bioaerosols in Your Home

Many bioaerosols thrive and can live in the air in your home. These bioaerosols can very negatively impact your health and cause illness and disease. This is especially a concern if you have young children, older people or people with existing health conditions.

Choosing the Best Air Filter for Your Home

Replacing your air filter is one of the small things you can do that can greatly affect the quality of air inside your home. Since many illnesses are associated with airborne contaminants, indoor air quality is a very important consideration.

HVAC and Your Pets

If you have pets, there are several things you can do to make your home and theirs safer, healthier and more comfortable for all of you.

Benefits of UV Germicidal Light Protection

by Laurel | Nov 20, 2025 | Indoor Air Quality | 0 comments

UV Germicidal Light Protection kills harmful biologic microorganisms, mold, fungus, bacteria and viruses can grow and thrive in damp environments. One such perfect environment is none other than your evaporator coil inside your furnace or air handler. With the continual cycles of condensation and draining, it can be an ideal damp hotbed for these contaminations to grow and flourish in.

These contaminants can enter your air right through your HVAC system and thus contaminate your air and make the air you and your family breathe very unhealthy. This can lead to or worsen respiratory and other illnesses. Additionally, they can lead to unpleasant odors which then circulate throughout your home.

These lights do not address dampness in other areas within your home where growth can occur. It is important to eliminate any areas where there is dampness that can lead to mold growth.

Dirty, Contaminated Evaporator Coil

Many people are quite surprised to find out what their evaporator coil looks like after years of use without chemical cleaning. It is quite appalling when you consider that all the air your breathe in your home travels through this area and becomes contaminated, thus contaminating your air.

Contaminated indoor air can contribute to many health issues. Keeping your indoor air quality high is important for your health and comfort.

UV Germicidal Light

UV Germicidal Lights work to actually kill microorganisms, mold, fungus, bacteria and viruses and prevent them from becoming airborne. The technology utilizes strong UVC to disable the biologic DNA/ RNA of microorganisms using 200-280 nm within the coil or ductwork.

These UV Germicidal lights work extremely well in sanitizing biologic growth within your HVAC system. These lights are very powerful with their continual assault on mold, mildew, bacteria, viruses and biologic micro-organisms and preventing them from becoming airborne.

UV Germicidal Light with Odor Control

The installation of the UV Germicidal lamps with odor control will eliminate the growth of biologic microorganisms and also eliminate any odors caused by such contaminants as well.

These lights are installed in your indoor coil or ductwork and work continually.

Care and Maintenance

UV Germicidal Lights are relatively low maintenance, though the bulbs do need to be changed out generally every two years.

Conclusion

If you’re concerned about mold, viruses, or bacteria in your home’s air, HVAC UV germicidal lights can be a smart upgrade. They’re especially useful for households with allergies, asthma, or immune-compromised members. However, they should be seen as part of a complete indoor air quality strategy, not a standalone solution.

These lights are an important piece in improving your indoor air quality, but other strategies are also important to consider:
