Here are a few simple facts you should know about your HVAC system to help you to get the most out of it.

What Is Your HVAC System

Your HVAC system refers to your residential or commercial H-heating, V-ventilation and AC-air conditioning components. Technically, this includes whole structure central heating and cooling as well as window-installed air conditioning units and space heaters in individual rooms.

Whole-structure systems are the focus of this article because they're the most popular, most efficient and most cost-saving. These systems typically consist of an outdoor unit, an inside unit, a filter and a web of duct work.

Not All HVAC Systems Are Created Equal

There are several types of HVAC systems available for installation including those with heat pumps, AC/furnace combinations and gas furnace hybrids that rely on heat pumps. It's important to know that the HVAC quality and efficiency can vary greatly, even while they're all required to follow regulatory guidelines for performance.

Whether you're buying a brand new HVAC system or giving your older unit an upgrade, it's important to work with a professional HVAC service provider who can recommend the most reliable and efficient units available.

The ideal HVAC contractor will be able to discuss alternate heating and cooling methods including solar hybrid systems.

What Is A Filter MERV?

The MERV (Minimum Efficiency Reporting Value) is merely a way to rate the efficiency of filters through a numbering system that ranges from 1 to 16. The lower ratings (1-4) are the least efficient, removing only up to 80% of contaminants. This rating is typical for filters that are fiberglass, disposable or washable. At the higher ratings (13-16), electronic filters remove the most contaminants at up to 98%.

A Higher MERV Rating Is Not Always Better

Higher MERV filters are better at blocking contaminants but can add to your HVAC operating cost. They reduce air flow and can cause your system to work harder. Lower MERV filters are more energy efficient but aren't likely to restrict contaminants that might affect those who suffer from allergies or other respiratory ailments.

It's important to have the right combination of available air flow, adequate air filtering and efficient energy usage. Check with your HVAC professional.

What's The Best AC Temperature Setting

A comfortable room temperature is subjective but the desire to save money on energy and utility bills is universal! The majority of people find 72 degrees to be cool enough when the humidity is adequately handled by the HVAC system.

Saving more money is as easy as raising the temperature on the indoor thermostat setting. Every degree counts in dollars and 'sense.'

VAC Maintenance Pays

Don't underestimate the importance of routine, scheduled maintenance for your HVAC. Proper maintenance means less money spent on repairs and more saved on heating and utility costs.

Spring and early Summer are the best times for AC check-ups; Fall is ideal for Heating maintenance. Be prepared with peak operating efficiency prior to needing it.

Advantages Of Dual Fuel Heat Pumps

The efficiency of heat pump HVAC systems are steadily growing in popularity because they do it all; they provide cooling in the warmer months and economical heating in the cooler months.

Program your dual heat pump system to operate with the outdoor temperatures. Determine an upper range to trigger the electric heat pump and a lower range to activate the alternate fuel pump.
