HVAC (pronounced h-vack or spelled out) stands for Heating, Ventilating and Air Conditioning. The three functions of heating, ventilating, and air-conditioning are closely interrelated. All seek to provide optimal comfort, acceptable indoor air quality, and reasonable installation, operation, and maintenance costs.

A fan draws indoor air in through vents called return grills located throughout your home. The air travels through ducts that run to your systems’ air handler, where it is returned into the conditioned space through supply vents or registers in your wall, ceilings or floors.

There’s no one-size-fits-all answer. The frequency of filter changes is driven by how much your heating and air conditioning system operates, which is also driven by your individual climate.

Start by checking the system’s filters at least once a month. Hold the used filter up to the light and compare it to a clean “spare.” When light is obscured by captured dust and dirt particles, the old filter should be changed. Keep a record for one year and then replace the filter on that basis. At a minimum, it is always a good idea to change filters at the start of the heating and cooling seasons and then in between according to your need. Also, it is a good idea to have your heating and air system checked at the beginning of heating and cooling season to insure proper operation.

Although your present furnace or air conditioner may be working, if it is more than 10 years old you should consider replacing it with a new high efficiency system. A new heating and air conditioning system could save up to 50 percent on energy costs, and save you money in the long run on heating repairs. While these products save you money on your utility bills, they also offer a better degree of comfort within your home.

At One Hour Heating and Air Conditioning, we’re, “always on time… or you don’t pay a dime.” Our customers’ time is our number one priority, so we’ll stop at nothing to guarantee punctual service and quality installation and repair work that gets done right the first time.

Classic Air’s One Hour Heating and Air Conditioning has been a Hampton Roads ran and operated business since 1979, assisting the Tidewater region with all their heating and air conditioning needs for over three decades. In fact, residential heating and air conditioning is all we do. When you call us up, a service coordinator will make an appointment with the highly-trained comfort advisor or service technician that’s nearest to your home, using our computerized scheduling system. That way we arrive when we say, instead of promising you a time and then apologizing when we’re late by a few hours or days. And anyone who visits your home undergoes mandatory background checks and pre-employment drug screenings so that you can trust them with your family. They’ll never curse, swear, smoke or chew tobacco. They’ll even put on yellow shoe booties and lay down drop cloths to keep your home as clean as when they arrive. Head over to our guarantees page and have a look at all of the promises we make to ensure your service and our reputation.

We’re fully staffed to respond to your call everyday from 7am to 11pm everyday, and we offer around the clock, 24/7 emergency service available to customers all over Hampton Roads including Virginia Beach, Norfolk, Chesapeake, Portsmouth, Suffolk, Hampton, Newport News, Poquoson and Williamsburg.

So give us a call at (757) 868-7600, and get the expert service and installation from One Hour Heating and Air Conditioning that fits your schedule.

Replacing your system is one of the biggest financial decisions you will make. The reason for this is that the life expectancy of a system is around 12 years. When choosing a contractor, pick a company to install the unit based on quality and customer service, not solely on price. The name brand of the equipment is not as important as the installing contractor. Another thing to keep in mind when replacing a system is that the duct system you are connecting to is sealed tight with the proper amount of return air. With the new higher efficiency units, you also have to be careful that you replace your system with the proper sized unit so you don’t end up with a house that is cool but has high humidity. Do some homework, pick quality contractors, and find someone you trust and you will have a successful installation that will bring you years of comfort and the least amount of overall cost.

I also like that they send multiple types of notifications... Read More
