almost spring, and my electronic desk is accumulating
more advice than I can share with you in a lifetime.
interesting bit of counsel comes from Lennox, which
manufactures heating, ventilation and air-conditioning
weeds and grass collect on outdoor condenser units
during the fall and winter, resulting in blocked air
flow and reduced energy efficiency. Clearing the debris
allows for unrestricted airflow, improving an
air-conditioning system’s efficiency, reducing
operating costs, keeping the air clean, and increasing
addition, Lennox advises, changing standard air filters
once a month (other types, such as pleated and HEPA
filters, have longer life spans) is the single most
important thing homeowners can do to prevent a system
from working harder than it needs to, which saves money
on electricity bills. It’s also important to ensure
that ductwork is clean and in good condition.
if homeowners keep their air-conditioning systems clean,
they still might be letting air — and dollars —
escape. Adding easy-to-use blow-in insulation will
reduce the amount of heat that flows from outdoors into
a home, which will lower cooling costs and make the home
also is a good time for homeowners to inspect and repair
loose siding and seal windows and doors with caulk and
weather stripping. That will keep cool air from escaping
and increase energy efficiency.

your current unit:
bills continue to rise.
air quality and humidity are poor.
repairs begin to account for a large portion of

levels of performance cause inconsistent cooling.

thermostat with something a little smarter, if you catch
