Tips & Advice

Tips & Advice From Our Experts

  • Sewer Mainline Stoppage - Foreign Objects
    Unless there is something structurally wrong with the sewer mainline, they rarely back up. Even back-ups that seem to be caused by foreign objects (often graciously donated by toddlers ;)) are typical because of a structural issue with the line. It's uncommon that the cause of a backup is solely the foreign object's presence in the pipe. What more commonly happens, is the object passes through a smaller secondary line that comes from a sink or toilet and enters the mainline. When something like a child’s toy gets flushed down the toilet and it lodges at the connection or beyond, the problem is not that a child’s toy was flushed down the toilet, it is that there is an offset in the sewer line that is in need of repair.

  • 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.

  • 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.

  • How Accurate Are Phone Quotes for Water Heater Installs?

    Be wary of a company that is willing to price quote water heater replacement or new installation over the phone. It is difficult to give an accurate price without seeing the water heater installation site first.

    There are many variables that affect pricing, and the type of installation is unique to each project. The type of unit a homeowner currently has, what they want to replace it with, and what changes are needed to bring the installation up to current code are all factors. Codes change regularly and water heaters must always be installed to code. Over the phone, you're likely to get a low-ball price, but when the technician arrives and assess the circumstances, the price could change substantially. Best to have the technician analyze your install site first, so you know the real cost up-front!
