September 4th, 2023

There are many options for how to heat your home these days. Forced air heat can be provided by a furnace that uses gas, propane, heating oil, or electricity to heat air that’s conducted through the same ductwork your central air conditioner uses. Heat pumps can warm your home, not by generating heat but by transferring it from one place to another.

It might seem like boilers are a very old-fashioned way to heat a home, and you might imagine ornate, antique radiators when you think of them. Modern boilers are not quite the same as the old-fashioned ones, and they’re still a popular choice for home heating. Here’s why.

July 24th, 2023

Ductwork for central air conditioning became common in the US in new homes that were built starting in the 1970s. For the first time, people had control over the temperatures of their homes, not just when it was too cold outside, but also when it was too hot.

Problems can occur with ductwork, especially if it has been in use for many years. What problems? We’ll give you a list.

The compressor is the single most expensive component of your air conditioning system, and you do not want to ever have to replace it. Often, when a compressor fails completely, it’s a better investment to replace the entire AC system than to get a new compressor.

Your air conditioner has both an indoor unit, or evaporator, and an outdoor unit, or condenser. The compressor is located in the condenser unit and it does the critical job of pressurizing the refrigerant to keep it flowing through the system, taking in heat from your home in the evaporator coils and releasing it from the condenser coils.

So how do you protect your compressor and keep your air conditioner running for as long as possible? Know how to catch problems early! Here are some tips.
