Our Most Common FAQs

We Can Answer That!

We know the world of HVAC and plumbing can be a little overwhelming for those who aren’t familiar with it. That’s why at Oliver, we’re happy to answer any questions (short or long) you may have about your home or business’s operations. Here are some of our most common FAQs, answered:

What’s the best air conditioner size for my home?

If the size of your home has changed through an addition or other renovations, or you have made enhancements that affect air flow (such as window or door replacements or changes to your insulation), it may be time to have a professional perform a new Heat Load Calculation on your home to assess the proper size air conditioner. If you are installing one for the first time, a Heat Load Calculation is recommended.

How can I even out the heating and cooling of my home?

You can partially close the registers in the room(s) that are too hot or cold in order to force more airflow into other rooms of your home. (It’s never a good idea, however, to close the registers completely.) Another possible solution is to invest in a furnace equipped with a variable speed blower motor. These furnaces are designed to overcome airflow problems and keep the airflow steady throughout the entire house.

How does an air conditioning system actually work?

An air conditioning system consists of 2 parts: an outdoor unit (where liquid refrigerant is contained) and an indoor coil (where the refrigerant is pumped into). As the air moves across the air conditioning coil, the refrigerant removes the heat and moisture from the air by condensing it on the cold surface of the coil. Thus, an air conditioner not only cools, but also dehumidifies the air.

When should I call a plumber?

This depends on your own skill level and experience in making repairs. If the repair could cause water damage if not performed properly, you may want to call a plumber. It’s also a good idea to call one if you have a problem that needs to be addressed immediately (such as a major leak).

How do plumbers find leaks?

Finding leaks is mainly a visual process: a plumber will inspect all of your pipes for leaks and may use a dye test kit to identify a leak in a toilet. We offer FREE dye test kits as a courtesy to our customers, just give us a call or use the Request Estimate form to let us know you would like one.

If I go away for an extended period of time, what temperature should I set my thermostat to?

We recommend 55 degrees. It’s low enough to save you energy and money but a good temperature to protect your pipes and other vital parts of your structure.

How often do my filters need to be changed?

You should change your standard furnace filter every 6-8 weeks. Use your own judgment as to when to change it, but don’t let the filter get clogged, as this can cut down on the efficiency and/or cause damage to the unit.

What can reduce the air quality in my home?

A wide range of particulate matter can be in your home’s air including dust, pollen, animal hair and dander, dust mites, mold spores, cooking grease, smoke, bacteria, viruses and other respiratory diseases. These types of contaminants won’t affect all people, but they can affect some pretty seriously.

Why should I invest in a maintenance plan?

Our maintenance plans provide peace of mind. When your HVAC system is running at its best, you’ll worry less about major damages or a shortened lifespan. You’ll also get priority service, savings on repairs, and no residential overtime charges.

Which HVAC maintenance plan is right for me?

It depends on the level of protection you’re comfortable with. Most of our customers choose our Gold maintenance plan because there are no charges for covered repairs. If you have new equipment, you may find that the Silver maintenance plan provides you with sufficient coverage.
