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.

The importance of changing your system’s HVAC air filters regularly cannot be over stated. It is a crucial aspect of your HVAC system running at it’s peak efficiency. It is also critical in filtering out potentially dangerous allergens, bacteria, dirt, debris from the air you breathe.

You should look at your HVAC Air Filters every month and replace them at least every three months, OFTEN every month if you have pets or high traffic.

Dirty Air Filters

HVAC Air filters become dirty as they clean your air. Trapping dirt, debris, hair, chemicals, mold spores, bacteria and other contaminants. It may surprise you how quickly this can happen.

As more and more foreign materials become trapped in the fibers of the filter, less and less air flow occurs. This can negatively impact the operation of your HVAC equipment and make it work harder using more energy. Additionally, your system becomes less and less able to filter out those contaminants leaving them in the air you are breathing.

Pets heavily contribute to contaminants in the air and changing your filter more frequently is important if you have pets.

MERV Ratings

The MERV Rating used to rank HVAC Air Filters indicates the Minimum Efficiency Reporting Value. The higher the ranking the greater the filtering. For residential HVAC systems, the best MERV ratings are generally #4-12 depending on the needs. Higher filtrations are used in more industrial situations. They cause too much resistance when used with residential HVAC equipment.

MERV #7 rating can greatly reduce mold spores. HEPA filters can help remove allergens and bacteria.

Only use high quality, pleated filters which are the correct size.

Whole Home Air Purification

To add another barrier against harmful germs, mold, VOCs, viruses, bacteria and other contaminants, consider adding a whole home air purifier to your home. Installed by an HVAC technician, these devices operate silently, effectively and efficiently to cleanse your air. Create a healthier environment in the most important place- your home.
