  5. What is SEER?

    S.E.E.R. (Seasonal Energy Efficiency Ratio) is an efficiency rating for HVAC equipment, much like how miles per gallon (MPG) is used to rate automobile efficiency. We all understand that if you drive 300 miles and consume exactly 20 gallons of gas, then your vehicle’s fuel efficiency (MPG) is 15 miles per gallon (300 miles divided by 20 gallons). A vehicle that gets 18 MPG would be more efficient (less costly) to operate, and a 12 MPG vehicle is less efficient (more costly) to operate. For HVAC equipment, S.E.E.R. follows the same rationale. The higher the S.E.E.R. rating, the more efficient and environmentally friendly the equipment is.

  6. What does it mean to be EPA Certified?

    According to the Clean Air Act, any professional working on refrigeration and air conditioning equipment must possess an EPA certification. Obtaining EPA certification indicates that you are expertly qualified to build, repair and assess small appliances and low- or high-pressure appliances.

  7. What does it mean to be NATE Certified?

    Founded in 1997, North American Technician Excellence (NATE) is the nation’s largest non-profit certification organization for heating, ventilation, air conditioning and refrigeration technicians. Headquartered in Arlington, VA, NATE is the certification organization governed, owned, operated, developed and supported by the entire HVAC/R industry. NATE certification tests represent real world working knowledge of HVAC and HVAC/R systems. Developed by a committee of industry experts nationwide, NATE exams represent HVAC/R topics pertinent to contractors, educators, manufacturers and utilities alike. All of the NATE tests are rigorous, multiple-choice, knowledge-based tests and validate a technician’s knowledge.

  8. How often do I need to change my filter? Is it really that important?

    Filters need to be changed when there is a build-up of dirt, dust, and debris. You can usually tell when a filter needs to be changed by just looking at the filter material. If it is discolored and you can see debris, odds are it’s time to replace it. A good rule of thumb is once every 30 days for the “disposable filters” and about 2-3 months for the thicker, pleated filters. When in doubt, take it out. A dirty or overused filter can create a blockage for the air trying to circulate through your home. When this happens, your air conditioner’s coils can freeze up causing the whole system to shut down. Believe it or not, regular filter changes are quite crucial to the operation of your HVAC system.

  9. How can I reduce the number of airborne allergens in my home?

    There are a number of things you can do to reduce allergens in your home. One of the most effective methods would be to replace your home’s duct system. Many people don’t realize this, but a vast amount of the homes in the Huntsville area were built during the same period, about 25-30 years ago. While the air conditioning and heating equipment have likely long-since been replaced, the duct systems for most of these homes have not been touched since they were installed. Over the years a duct system can develop leaks that break the seal that separates your conditioned air from the elements, opening the floodgates for all sorts of contaminants. If you haven’t serviced or replaced your duct system, you could have dust mites, dirt, or even mold caked to the inner walls that the air you breathe passes over. If you are concerned that your duct system is contaminated or leaking air, just give us a call. We will assess your duct system and inform you of any damage free of charge.

  10. How can I increase the efficiency of my system and decrease my utility bill?

    Everyone knows that if you don’t get your car serviced from time to time, you will pay for it in the long run with more costly repairs, lessened fuel efficiency, and a lower life expectancy. It’s no different for your HVAC equipment. An air conditioner requires regular maintenance in order for it to run at peak performance. Preventative maintenance should include cleaning your refrigerant coils so that the transfer of heat from the inside to the outside (or vice versa) is not inhibited by dirt and debris. The heating and cooling components should also be checked in order to catch small problems before they become big ones. If you stay on top of your HVAC system’s maintenance then it will work for you, instead of you working for it. Check out our Services page to find out more about our preventative maintenance plan, the Safety and Efficiency Agreement.
