It’s important to have maintenance done on your HVAC system twice a year. Most people clean their system during the spring and before winter.  Cleaning your system during the spring is the best time to have your HVAC contractor conduct a pre-summer inspection of your system.  The summer months get hot and humid, so it’s important to have your system inspected to ensure it’s working properly.

Listed below are summer HVAC maintenance tips from

  • Check thermostat and furnace system controls. This insures that the starting cycle is working properly so you stay comfortable and save energy.
  • Make sure the electrical connections are tightened and lubricate all HVAC moving parts. Loose electrical connections and lack of adequate lubrication reduces the life of the unit components leading to increased energy use.
  • Make sure the condensate drain is working properly. A plugged drain or pipe can cause water damage, and affect the humidity levels in your home.
  • Clean the evaporator and air conditioning coils. Dirty coils can higher your energy bills leading you to spend more money.
  • Check the air conditioner refrigerant level. The wrong level of refrigerant can affect your system efficiency and increase your costs.
  • Make sure the blower components are properly adjusted. Improper blower components can reduce efficiency up to 15 percent.
  • Change air filters regularly to ensure system efficiency.

Do you know what an HVAC contractor should test for when installing new high efficiency equipment? Before investing in a new high efficiency heating and cooling system, you need to make sure you select a contractor that installs equipment based on facts, testing, and science. Unfortunately, many HVAC contractors offer advice on new high efficiency heating and cooling systems based on opinions and guesses. When selecting an HVAC contractor, make sure the contractor meets the minimum criteria listed below:

  • Computerized “Manuel J” Load Calculation – This is a room by room scientific test that will determine the right size equipment for your home.
  • Room by Room Airflow Calculation – This is a scientific measurement of the amount of air coming out of the air vent in each room. This will ensure your new system heats and cools your home evenly.
  • Air Duct Leakage Calculation – The typical duct system in a home leaks 25-40%. The air duct leakage test identifies where the leaks are located so repairs can be made.
  • Air Flow Leakage Reduction Guarantee – Get a written guarantee that the duct system will leak less than 10%, or that they will guarantee 75% less air leakage once the new system is installed.
  • Infiltrometer Blower Door Test – This is a scientific test that measures the level of air leakage in the entire home. Understanding this will help solve high utility bills, unhealthy indoor air, musty odors, excessive dust, humidity issues and hot and cold spots throughout the home.

Imagine an “optical battery” that could convert sunlight to electricity for a small fraction of the cost of today’s photovoltaic cells.  Well, you may not have to imagine much longer.  Scientists at the University of Michigan may have discovered a breakthrough in solar power technology that could drastically reduce the cost of solar power.  It was once believed that the effects of light’s magnetic field were so weak they were irrelevant when it came to solar power.  However, according to physics professor Stephen Rand, that is not true.

It was discovered that if light is intense enough, it can generate voltage from magnetic effects 100 million times stronger than earlier predicted when traveling through nonconductive material.  These magnetic effects can be bound for electric power production.  Stephen Rand states:

“This could lead to a new kind of solar cell without semiconductors and without absorption to produce charge separation in solar cells, the light goes into a material, gets absorbed and creates heat. Here, we expect to have a very low heat load. Instead of the light being absorbed, energy is stored in the magnetic moment.  Intense magnetization can be induced by intense light and then it is ultimately capable of providing a capacitive power source.”

So what does this mean?  It will be difficult to make this a low cost power producer because the intensity of the light must be 10 million watts per square centimeter.  For comparison, ordinary sunlight produces less than one watt per square centimeter.  However, William Fisher believes new materials such as transparent ceramics combined with focused sunlight could work at lower intensities of light greatly reducing the cost of solar power and becoming a reliable energy producer.  This breakthrough could have a major impact in the heating and cooling industry!

When it’s time for your cooling and heating system to get it’s regular maintenance, do you know what services an HVAC technician should perform?  It’s important to perform the necessary maintenance on your cooling and heating system to ensure that your unit is working as effectively and efficiently as possible.  You should have an HVAC technician perform annual check-ups once in the spring and fall on your cooling and heating system to avoid any problems.  According to, here’s a list of services that an HVAC contractor should perform:

  • Check for the correct amount of refrigerant
  • Test for refrigerant leaks using a leak detector
  • Capture any refrigerant that must be evacuated from the system, instead of illegally releasing it to the atmosphere
  • Check for and seal duct leakage in central systems
  • Measure air flow through the evaporator coil
  • Verify the correct electric control sequence and make sure that the heating system and cooling system cannot operate simultaneously
  • Inspect electric terminals, clean and tighten connections, and apply a non-conductive coating if necessary
  • Oil motors and check belts for tightness and wear
  • Check the accuracy of the thermostat
  • Lubricate all moving parts
  • Check and inspect the condensate drain in your central air conditioner, furnace and/or heat pump (when in cooling mode)
  • Check the controls of the system to ensure proper and safe operation. Check the starting cycle of the equipment to assure the system starts, operates, and shuts off properly
  • Clean evaporator and condenser air conditioning coils
  • Clean and adjust blower components to provide proper system airflow for greater comfort levels
  • Check all gas (or oil) connections, gas pressure, burner combustion and heat exchanger

Many of you have probably heard of the term SEER before, but do you know what it means?  SEER stands for Seasonal Energy Efficiency Ratio.  According to the Air Conditioning, Heating and Refrigeration Institute, SEER is a measurement of cooling efficiency.  It is the rating of efficiency a unit delivers, by determining the amount of energy needed to produce an overall British Thermal Unit (BTU) of cooling capacity over the course of a cooling season.  SEER ratings typically range from 13 to 23, with the highest numbers indicating the most efficient units that offer the most energy savings.  It’s important to know that the higher the SEER rating, the higher efficiency, resulting in lower operating costs.  On the other hand, the lower the SEER rating, the lower efficiency, resulting in higher operating costs.  Invest in a higher SEER unit today and save a lot in the long run. You won’t be sorry!

North American Technician Excellence (NATE) just announced it is extending certification for HVAC technicians called to active duty. As soon as NATE-certified military service members deploy, their NATE certification is postponed until they return home. NATE is extending certification for HVAC technicians serving active duty to guarantee that the technician comes home with the same qualifications as he or she left with. When the technician returns home from active duty, he/she will receive all new NATE certification documents. According to NATE, the expiration date of their certification will be extended to reflect their time in service.

“All of us at NATE feel that this policy is critically important for our NATE-certified technicians active in the military, and it is the least we can do to support our troops,” said Patrick Murphy, vice president of certification for NATE. “The last thing these honorable and esteemed professionals need to worry about is the status of their certification. By stopping the clock on their NATE certification, we aim to do our small part in helping these technicians pick up where they left off when they return from serving our country.”

HVAC technicians called to active duty can simply contact NATE when they return home to extend their certification and obtain their new documents. NATE certified technicians are thrilled by the news and are pleased with NATE’s gesture to extend certification.
