Do This One Thing To Get The Best Warranty On Your Air Conditioner Replacement

Monday, June 22nd, 2020

It’s once again that time of year when replacing your air conditioner becomes more and more a reality for many Lowcountry homeowners.

Temperatures in South Carolina become unbearable and the humidity levels go beyond balmy.

That means your HVAC system is going to be working overtime to help you and your family escape that outdoor heat and humidity. The extra load on your HVAC system could cause it to develop issues and you could be in for a slightly warmer summer than you’d probably prefer in Charleston.

When you do end up replacing your air conditioning, whether that be from a total breakdown or poor performance due to age, the last thing you want to worry about is something immediately breaking down.

A brand new system shouldn’t give you much cause for concern, but in case something does happen you’ll want to make sure you get the best warranty possible to cover any more expenses that may come with repairs and/or replacements.

Typical HVAC Warranty Types

Like any new equipment right off of the assembly line, heating and air conditioning products will almost always come with some sort of base warranty. These basic warranties are very limited (in fact most are called “base limited warranties”), in that they will only cover a short time period and are limited only to manufacturer’s parts defect (more on this below).

The next level of warranty typically comes in the form of a registered warranty. These, too, are “limited” and your product has to be registered with the manufacturer within a certain time period to qualify for any extended warranty coverage.

What Most Warranties Don’t Cover

While opting for either the base or registered warranty type helps keep you covered within a certain time range, as mentioned above, these will only cover the cost of the manufacturer’s defective parts. You will still need a professional HVAC company to come and replace those parts, so you’ll have to pay for the labor involved with performing the replacement.

On top of this, if the issue happens to be caused by a poor installation (or by an unlicensed company in some cases), you’ll be out of luck on both parts and labor — which may mean the worst-case scenario: replacing your replacement air conditioning.

Choose A Licensed, Manufacturer-Trained HVAC Company To Get The Best Warranty

Most manufacturers want to offer the best warranty possible for their products, so to help ensure this they offer product-specific installation and service training to their local HVAC companies.

This training helps eliminate any issues resulting from poor installation practices and keeps your warranty for defective parts fully intact.

On top of keeping yourself covered from installation issues, manufacturer-trained HVAC companies have the ability to offer you extended warranties that can include not only more coverage on parts, but can also include labor as well.

We hope you never need to worry about using your warranty, but in case you do be sure to get the best one possible — it will help you save time & money and help avoid any long, hot summer days this year.

Can Heating & AC Zone Systems Help You Save Money?

Tuesday, January 20th, 2015

Many homes and businesses in Charleston today heat and cool multiple areas (or zones) from a single Furnace/Air Handler. Consider a home that has a large second story space with a smaller third story area, or a business with 3 offices and 1 large retail space. Rather than installing individual systems for each location (which is expensive), a single properly configured furnace/air Handler unit can do the job, when combined with a zone system.

With a multi zone system, multiple sections of a business or home structure can maintain set temperatures through the use of coordinated thermostats and dampers. Zone systems can be deployed with Electric, Natural Gas/ Propane (LP), or Geothermal HVAC systems. Managing the flow of air requires more mechanical parts, including electric dampers, zone panel boards, bypass dampers, and a thermostat for each zone. Some systems can address up to 8 zones within one Furnace/Air Handler configuration.

Multi Zone System

Zone systems can Condition one specific part of a structure without wasting energy trying to condition the remainder of the structure. The sophistication of the installed zone management componentry (which can include: a zone panel, a variable speed blower, bypass duct(s) and more) determines a system’s ability to address a variety of fluctuating conditions. The goal is to maximize performance with a minimum number of systems. Why add another system when you could just upsize the equipment (to correct tonnage) and zone each space correctly?

A Zone System Does NOT Automatically Equal Low Utility Bills

As with any system required to manage many variables, zone systems must be designed and installed correctly before maximum efficiency can be achieved. Each zone in a home or business requires a set amount of airflow, expressed as CFM (or Cubic Feet per Minute) to condition the zone to desired temperature ranges. The components of each zone must be configured to deliver the proper number of CFM to achieve success.

It is not unusual (but it is unfortunate) for home and business owners to experience VERY high utility bills due to a variety of problems including: improperly sized ducts, non-calculated CFM, poor airflow, and single speed blower drives. For example, if a two-zone structure is installed utilizing a single speed blower drive the motor will only operate at one speed. In other words, it does not fluctuate airflow when one zone opens or closes. This causes inappropriate (excess and poor) airflow to the supply ducts.

To realize the full potential of a zone system, IT IS A MUST that a Variable Speed Motor be included in the blower drive configuration. These motors operate using static pressure levels. As one zone closes, the pressure in the ducts rises, and the blower slows down. This helps the zone(s) that is open to satisfy much quicker saving the consumer money on energy costs.

Failure to achieve maximum efficiency with a zoning system is rarely an equipment issue. It is typically related to poor design or installation of the HVAC ducts, blower motor(s), and caused by a lack of knowledge on behalf of the contractors installing these systems.


One of the best Zone Panels in the industry is made by Honeywell. It has the capability to operate with any system, thermostat, and damper type. Many home/ business owners do not know what type of equipment they are relying on to keep them comfortable. With a digital/ LED display of zones the Honeywell zone panel portrays which zones are operating and under what mode they are operating.

This panel also comes with a 5 year manufacturer warranty. Another issue with improperly sized ducts in a zoned system is the inability to remove humidity (moisture) from the home. This results in failed blower motors in many cases due to excessive moisture exposure, and these motors can cost several hundred dollars.

In some cases a bypass duct will have to be installed to keep the static pressure in the ducts low when only small zones are operating. The best option when installing a bypass duct is to implement an external static pressure bypass damper.

This damper works off of static pressure (just like the variable speed blower) and modulates open/ closed according to the different pressures. This helps keep a system from short cycling and ultimately satisfying quicker.
