Important Information Regarding the Coronavirus disease (COVID-19)



If you have air conditioning or hot air heating you will have an air filtration system or air filter. During this time of uncertainty, it is important that this filter gets replaced or sprayed with Lysol disinfectant spray at least once a week. Your air filter is a location that bacteria, virus and mold collect on. An added benefit would be while the filter is removed to put your thermostat’s fan setting to the on position and spray the Lysol into the grill or duct for 10 seconds, this will help disperse the spray throughout the duct system and air around as well. Also, research suggests that increased humidification has a large impact on reducing the transmission of some airborne virus, as will the level of filtration within a ventilation system.

We strongly suggest that sometime prior to the summer to get your  air conditioning coil, and condensate pan chemically cleaned.

American Society for heating, Refrigerating and Air-Conditioning Engineers came out with guidance related to COVID-19. It recommends a focus on:

  • Supplying clean air to susceptible occupants
  • Containing contaminated air and/or exhaust it to the outdoors
  • Diluting the air in the space with clean and filtered outdoor air
  • Cleaning the air within a room

There are some items that do in fact help kill bacterial, virus and other vocs in the air within the home and these are referred to UV lights. Please see below for more information,

Water Heater Repair or Replacement

When You Should Replace Your Water Heater.

Cold Showers, lack of heated water, water damage, these are things no one likes to deal with, and like any home device, water heaters can break down over time and need to be repaired or replaced.

5 “Signs” it’s time to replace your Water Heater:

1: Your Water Heater is too Old – A Standard Tank Water Heater on average lasts 8-12 years. Usually it’s at the 10 year mark you want to consider replacing unit. Even though your water heater is not showing symptoms of failure it’s better to replace the system as a precaution vs waiting for the unit to fail and cause possibly cause damage to your home. 

2: Rusty Water – If you are seeing pieces of rust or the water is rust in color. It’s possible the water heater has failed. Most Water heaters have a device called anode rod. This Rod is used to prevent the walls  of your water heater from rusting. When the anode rod  fails and the walls of the tank star to rust away, rusted sediment collects in the bottom of the heater and can start to cause the heated water to discolor and rust flakes appear in the water stream. You can remove this rust yourself, but you’ll have to drain and possibly flush the tank frequently.

3: Noise from the heater – If you hear  banging and rumbling from your water heater its time to consider replacing the unit. Sediment is building up and can cause the tank to leak.

4: Leaks – If your Water heater is leaking from any of it’s sides, bottom, or pressure relief valves (even the slightest)  then it’s time to replace the unit. You do not want to take a chance that the small drip today will become a flood tomorrow.

5: Cold Water – If you turn the hot water tap on the faucet and the water stays cold. It’s possible your water heater has failed and needs to be replaced.

If you see these “signs”, don’t wait until you’re dealing with a possible disaster.
