Residential Heating and Cooling Tips

Air Conditioning Tips

My air conditioning isn’t cooling well.

First, look at the thermostat and make sure it is set to “air conditioning” and not to “heat” or “fan”. Then set the thermostat to a comfortable temperature of 70-75 degrees. Be sure that the air filter has been changed prior to turning on the air conditioner and that all air vents are open and clear from obstruction.

How can I get the best performance from my air conditioning system?

During the hot summer afternoons keep the sun out by closing your drapes and blinds and this will help to keep the temperature down. Your unit may also need some refrigerant. Remember to have your air conditioning unit tuned up by a professional heating and cooling company before the summer hits.

The air conditioning unit has iced up.

Turn on some fans in the house to keep yourself cool and shut the unit down to allow time for it to thaw out. Call R.E. Robertson’s professionals to repair your unit at 410-757-0023.

Heating Tips

Winter Checklist

Make sure the filter has been changed before turning on the heat.

Have R.E. Robertson’s come out and service your heating unit in the fall to ensure that you’ll be warm all winter. Call us at 410-757-0023.

My heat won’t come on.

Check to see that the heat is set to “on” and that the thermostat isn’t set to air conditioning or fan. Then turn the thermostat up to between 70-75 degrees to see if the heat kicks on. If this doesn’t work, go to the circuit box and check to see if the breaker has been tripped. If none of these steps work call a R.E. Robertson’s service technician immediately.

My house is cold.

Bundle up. Check for window and door cracks that my need to be sealed. Make certain that all registers are uncovered and that the filter has been changed prior to turning on the heat. Close doors and vents to basements and all unoccupied rooms.

My heat pump is frozen.

Go to your thermostat and turn it to the emergency heat mode to thaw out the unit. Then call for a R.E. Robertson’s service technician to come and have a look at the unit.
