Here are some questions and answers that can help you with your home comfort needs. We will continue to update as customers bring more questions to us! Just ask!


Why should I get my Furnace, Boiler, and Air Conditioner cleaned/maintained?
There are many reasons why you should get your furnace, boiler, and air conditioner maintained. Here are a few:
1. Safety and efficiency - we check to ensure it is burning correctly and working efficiently.
2. Electricity/heat - we check the blower and make sure it is not overheating and not working inefficiently.
3. Health and Safety - we check the heat exchanger to make sure it is not cracked and not leaking CO.
Check our Furnace Maintenance​ page for details.


​How often should I get my Furnace and Air Conditioner maintained?
We recommend that you get your furnace maintained every year. We can detect leaks/problems early on and prevent them from turning into larger/more expensive problems.​


How long does a Preventative Maintenance take?

A Gas furnace maintenance takes approximately one hour and fifteen minutes. An Air Conditioning maintenance takes about an hour. An Oil Furnace maintenance takes about one and one half to two hours.

How can I pay for a maintenance, service call, or installation?
We accept cash, check, VISA, Mastercard, Discover, and American Express.

How can I schedule a maintenance?
We accept cash, check, VISA, Mastercard, Discover, and American Express.

Why are my utility bills higher than they used to be?

There could be a few reasons why your utility bills are higher. Your furnace might be a low efficiency furnace or working less efficiently than it should be. Also, your furnace could be using up more electricity than normal if yearly maintenances are not scheduled.

We strongly recommend scheduling your Furnace and Air Conditioner Maintenances/Tune-Ups yearly no matter how old or new the furnace is for peak efficiency.

How do Air Exchangers/HRVs work?
Air Exchangers (Heat Recovery Ventilators, HRVs) take fresh from the outside, temp it (slightly change the temperature closer to inside temp and circulate it through your home.  It moves old air outside through a venting system.  During the process, some humidity is removed from the air, to make your home more comfortable.

How can a Humidifier help me?

If you air is dry, upgrading your furnace with a humidifier will add humidity to the air that is already circulating through your furnace.  Adding humidity to your home will increase the temperature and make you and your family feel warmer.  A humidifier saves money because your furnace will not have to work as hard because you can set the temperature on your thermostat lower.

A humidifier can also prevent dry skin and dry throats!

Why do filters at the store range from 75 cents to $20 to even $50?

Choosing a furnace filter depends on a few factors.  It depends on your health, how hard you run your furnace, and how often you would like to change your filter.  Contrary to popular belief, in the summer your air conditioner works your blower motor at a higher speed than in the winter, therefore going though more filters.  A clogged filter causes your furnace to work less efficiently and and can cause bigger problems down the road.

 Monthly and Tri-monthly Filters

If you change your filter monthly and you don't have health issues, the 75 cent filters would work for you. They catch the heavier debris and dirt that could ruin your blower motor, though they do take out some pollen and mold spores. If changed monthly, it can do the job. If you are going to forget to change the filter every month, choose the $4 pleated filter that you change every 3 months. Its accordion-like appearance allows it to work longer without impeading the airflow.

6 Month to 1 Year Filters

If someone in your family or yourself have asthma or allergies, the $20 or the $40 filters are for you. Some work for 6 months and others for a year and they can filter out bacteria, dander, odors and smoke particles. You should wash or vacuum the filter monthly and take other steps to clean up your air and house as well. Use an air purifier to clean your air up either further!

What is HEPA Filtration?
Our favorite type of filtering is HEPA filtration. High Efficiency Particulate Air, or HEPA filters require no cleaning or maintenance to maintain efficiency, and studies have proven that HEPA filters actually increase in efficiency with use over their 3 to 5 year life ( Our Fantech HEPA filters (pictured above) are 99.97% effective and catch airborne particles and allergens. As you can see, there are 3 stages of filtering. The Pre-filter catches the larger particles, then the Odor Absorbing carbon filter captures and neutralizes odors from cooking and tobacco smoke, and finally the Certified HEPA Filter is 99.97% effective and should be replaced every 2 years.

How do you change a forced-air furnace filter?
As we have been discussing air quality and the importance of changing filters, it is necessary to explain exactly how to change a forced-air furnace filter. Knowing what is in the air should be enough to convince you to change yours regularly. The air in your home is filled with dead skin, dust mite feces, dust, mold spores, and more particles that can be filtered out as long you change it. It is fairly simple.

There are a variety of sizes, styles, and prices of furnace filters, but changing each of them is similar.

1.   Before you start, turn off your furnace fan. Either switch to off at the furnace, or at the thermostat, switch fan to off. 
2.   Locate your filter. It should be located near the bottom of your furnace where the ductwork meets with the furnace. This is where the air comes from your home, to be filtered and then sent back as warm or cold air through the top of your furnace.
It might be hidden behind a slot of sheet metal that can be moved. If you cannot find it, consult your furnace manual or call a service technician.
​3.    Grasp the edge of the filter and pull out of slot.
4.    Take the new filter, look at which way the arrow points, have it pointing toward furnace, the direction of air flow. Putting in backwards decreases efficiency.
5.    Close up slot, if needed. Change filter as recommended, for the 1 inch pleated filter, usually 2-3 months, depending on how much usage.
6.    It only filters the air if your blower is running. If you have a variable speed blower, keep it running at a low speed all the time for the best air quality.​ 

Should I get my ducts cleaned?  How often should I have my ducts cleaned?
If you do not know the last time you got your ducts cleaned, chances are they probably look as bad or worse than the picture to the left. Now your furnace filter's job is to catch all the dirt and dust before it circulates back into your home. But your filter does not stop the mold growth and does not remove allergens and other particles that sit in your ductwork.  Valley uses the RotoBrush Duct Cleaning Method. We use an easily portable vacuum (pod) and hose and brush system to get in all the crevices and parts or your ductwork.

Process:   We clean your registers, inside all ducts (supply and return), inside the furnace/blower, and also use a anti-microbial fogger to deter mold growth in your ductwork. The entire proces usually takes about 4 hours.


How often should you get your ducts cleaned?
There is no exact amount of time between duct cleans that we suggest. If you recently remodeled, did in-home construction projects, or simply decided to do some "spring" cleaning, duct cleaning is a good idea to consider.

I don't think you want the inside of your ducts to look like that picture!

Why should I choose a Mini-Split System?
Window Air Conditioning Unit Problems:
​Window Air Conditioning units are big, bulky and block the view from the window.

·  Compromised security means easier access to intruders.

·  Window Units do not ad resale value to your home.

·  Window Units run very inefficiently.

·  Inconvenient manual control knobs.

Do I need to winterize my Air Conditioner/Condensing Unit?
You do not need to do too much to get your condenser ready for winter.  We suggest spraying fan blades and fins to get dirt and debris out of condenser.    After the condensing unit dries out after spraying it dow​n, you are finished! DO NOT COVER it with a condenser cover or tarp.  That basically creates a home for animals in the winter.


What is a "pre-filter" for an Air Exchanger?​
The Pre-filter on Air Exchangers is the filter that removes the large particles before the air would pass through a HEPA Filtration system which removes 99.97% of all micro-particles and allergens.


What is Ultra-Violet Light Filtration?  Why should I consider UV Light to clean the air in my home?
Ultra-Violet Light Filtration

How Ultraviolet Light Works

Ultraviolet light possesses just the right amount of energy to break organic molecular bonds. As micro-organisms pass by the UV rays radiated from the ultraviolet lamp, this bond breakage translates into cellular or genetic damage for micro-organisms, such as germs, viruses, bacteria, fungi (like molds), etc. This results in the destruction of the micro-organisms.


Easy Installation
We install the UV Light Lamp System into your duct work, when the air passes near the light, it instantly destroys the bacteria, fungi, mold, mildew, and more.

Great Results
Enjoy a cleaner envirorment and healthier home for you and your family. Cut down on doctor visits and health problems caused by in home pollution!

How often do I change my HEPA Filter, Carbon/charcoal Filter, and my Pre-Filter on my HEPA Filtration System?
Changing the filters on my HEPA Filter

The great part about HEPA Filtration is that is removes 99.97% of particles down to 0.3 microns. Another great part is that you only have to change the HEPA Filter every 2-3 years and the Carbon Filter every 2-3 years.

The Pre-filter should be changed every 3 months of so. The picture below shows what each filter is.​​
