1.    What are the 3 most common causes for issues with HVAC Systems?  

•    Lack of Maintenance
•    Dirty Filters
– your HVAC system gets clogged up with dirt and debris and the airflow becomes restricted.  As a result, your system needs to work harder and overall system performance is negatively impacted.  It can cause the system to shut down, overheat, and/or utility bill to skyrocket.
•    Age

2. How can I improve my indoor air quality?

•    Increase air circulation – Your blower motor is responsible for circulating conditioned air throughout your home year-round. When you set your fan to run on “auto,” your blower can only circulate air when your air conditioner, heat pump, furnace, or air handler is running. If you set your fan to “on,” your blower can run even when your HVAC system isn’t heating or cooling your home. This means that the air in your home can circulate more frequently.
•    Check your HVAC filters – The longer the air filter stays in your system, the dirtier it will become. If it isn’t changed regularly, it can become clogged. Changing your air filter can also improve air circulation throughout your home. 
•    Schedule regular maintenance for your HVAC system - maintenance primarily ensures that your system is operating safely, scheduling regular maintenance for your HVAC system can also help improve indoor air quality.
•    Invest in HVAC indoor quality products- Sometimes your existing HVAC system needs a little help to address indoor quality issues. Adding indoor air quality products such as humidifiers, dehumidifiers, and air purifiers can help improve your health and comfort. 

3. What is the purpose of an air duct and what kind should I have in my home?

Air ducts are responsible for distributing warmed or cooled air throughout your home, and for keeping you comfortable. Improperly designed or failing ductwork can cost you a great deal of money in energy loss and in some instances, lead to a premature failure of your heating and cooling units.  Choosing the right ductwork design for your home’s ventilation is extremely important. Designing customized ductwork has its advantages:
•    Better HVAC system efficiency
•    Improved comfort
•    Easier construction
•    Longevity of your system

4. What are the benefits of preventative maintenance?

•    Longer life expectancy - Maintenance is an important step in extending the life of your heating and cooling system. A furnace or air conditioner can last up to 20 years. 
•    Home safety and comfort – During service appointments technicians will clean and inspect your internal components. This includes checking your furnace and air conditioner, replacing filters, and carbon monoxide testing. They will also take the time to explain what they find and any work that is recommended to resolve issues. 
•    Better air quality - All the air in your home passes through the furnace filter. Simply changing the filter removes trapped dirt, pollen, and allergens from your home. 
•    Lower energy costs - An inspection from a Grille Mechanical Contractors service technician ensures your HVAC system is working at peak efficiency. If not properly cleaned every year, your system could be losing up to 40 percent of its energy efficiency causing higher energy bills.
•    Reliable operation - While the AC takes center stage, your furnace sits idle for about six months. This allows dirt and dust to accumulate in the system components, which prevents your furnace from running its best. If you turn the system on in the fall without properly cleaning the fans, that dirt and dust will blow right back into your home. Internal system maintenance is best left to our service technicians; it’s a messy job and can damage your system if it’s not done properly.

5. Why should I replace my current HVAC system?

Over the years, a heating and cooling system can become less efficient. Oftentimes, the main culprit is regular wear and tear. If your home's comfort system is working harder to maintain the desired temperature, you may notice higher utility bills and the need for increasingly frequent repairs. If you are experiencing this, it may be time to consider a new system.
