Tips & Advice

Tips & Advice From Our Experts

  • What Is a Residential Split System?
    Not to be confused with ductless mini split systems, a residential split system is where you have the furnace or air handler in the house - either in the garage, hallway or attic, and the outdoor air conditioner (also known as the condensing unit ) is outside on the side of the house. It's called a split system because one is inside, another one is outside. Otherwise, there are HVAC package units where the whole system is combined, and it looks like a box that sits on top of the house.

  • How to Allergy-Proof Your Home
    As an allergy sufferer, I have spent years dust proofing my bed, my bedroom and obsessively cleaning my home from one end to another. As licensed heating and air conditioning contractor, I keep up with the latest and greatest in air filtration. And from personal and professional experience, I can tell you that the most efficient way to allergy-proof your home is through your home's central air conditioning or forced air heating system. Whole home air filters are built into the return air ductwork, trapping particles as air passes through. This type of system is passive; as long as the fan is running, consistently cleaning the air in your home. These systems provide very impressive results.

  • Easy DIY for Better AC & Heating Efficiency
    No need to call a heating and air conditioning repair or installation contractor for this easy task. Simply purchase a new air filter and replace the current one. Your air quality and efficiency will be improved by this simple step. Be sure to check your air filter every 30 days during summer use, and replace it when needed.

  • When to Replace Heating & Air Conditioning System
    A common question I get asked is, “When do I need to replace my furnace or air conditioner?" Actually, you can keep repairing virtually forever, but this is not necessarily cost effective. A good rule of thumb is: Replace when your heat pump or air conditioner is more than 10 years old, and your furnace when it is 15 years old (or repair costs start to exceed the value of unit). Heating and cooling equipment has become MUCH more efficient in recent years. Replacement of older, less efficient systems should absolutely be considered now based on current financing options, tax benefits, municipality rebates and low-interest rates. You should consider replacement if you have any of these concerns: System needs expensive repairs, the utility bill is too high, rooms are too hot or too cold, you have humidity problems, your home has excessive dust, or the system is too noisy.

  • Do You Have Dirty Sock Syndrome?

    Associated with residential split systems, the term “Dirty Socks Syndrome” describes an odor generated by environmental fungi and/or bacteria that accumulate on the indoor coil. They can be ‘activated’ by the combination of moisture and heat commonly produced in air conditioning system operation.

    Dirty Socks Syndrome can vary from mildly offensive odors described as smelling like old hair tonic, or moldy hay - to extremely offensive odors, often described in terms that would offend the more delicate sensitivities of the general public. “Dirty Socks” provides a good comparative description of the odor.

    Eliminating the contaminants would exclude the possibility of Dirty Socks Syndrome, whether or not the system is operating at or near design conditions. If you're experiencing Dirty Sock Syndrome, we're happy to advise on the best methods for removing the odor. Give us a call anytime!
