The Best of Rheem

Rheem has been manufacturing HVAC products since 1956. Since then they have been innovating in product lines such as water heaters, gas furnaces and HVAC. Some of the key innovations by Rheem in HVAC are highlighted below:

In 1998, Rheem introduced the Modulating 90 Plus gas furnace, which is extremely quiet, maintains the temperature within a ½ degree of the thermostat set point, and eliminates hot and cold spots effectively.

Rheem also innovated in the smart home market by introducing EcoNet in many of its products. This is newly-developed  technology that allows Rheem Heating, Cooling and Water Heating products to communicate with each other on one integrated network. The EcoNet Smart Home System allows homeowners to control and manage their Rheem products from anywhere via a mobile app or through a wall-mounted Control Center.

EcoNet notifies homeowners and contractors when the equipment needs service and provides timely diagnostics in easy to understand language. Rheem’s line of EcoNet-enabled water heaters is compatible with the Nest Learning Thermostat, Wink and Logitech’s Harmony hub.

The new Rheem Prestige Series EcoNet-enabled Modulating Gas Furnace is the industry’s first patented heating unit featuring a 97 percent AFUE rating. The variable-speed blower motor runs at a wide range of speeds to deliver better humidity control, while using less power. The patented heat exchanger design improves airflow, which reduces operating sound by 20% to deliver the quietest, most efficient gas furnace.

In 2017, Rheem launched its line of Rheem and Ruud branded ductless Mini-Split Heat Pump units. These include some of the most efficient and advanced single-zone and multi-zone heat pumps currently available for residential applications. Benefits of these appliances include being easy to install and maintain, quiet operation, precise temperature control and hassle-free filter access.

The Drawbacks

Rheem products usually are appreciated by customers for their quiet operation, efficiency and performance. However, many customers that own Rheem products complain of poor customer service. Also, the product warranty only covers replacement of parts and not labor.

The durability of their products also causes some customers to complain, as they need to pay for the cost of contractors replacing and installing the new parts..

Finding the Best Prices

When shopping around for installing or replacing central air systems, the cost can be huge. Obviously, you’ll want to get yourself the best deal possible.

Some tips that may come in handy:

First, buy in the winter. Demand for air conditioners is lowest at that time. Due to the low demand, retailers have excess stock in their inventory. To encourage sales, appliance stores usually offer discounts to incentivize buyers to make a purchase during the off season. To get an off-season discount from the HVAC contractor, wait until fall or spring to install the new system, as the contractors are not as busy.

Second, when it comes to the installation of your AC system, do not compromise on quality. You may save a few dollars by picking a cheaper installer, but the money you save will be a lot less than the extra bills you may have to pay due to a shoddy installation job. The cheapest quote may not necessarily be the best, especially if the contractor has many dissatisfied customers on Angie’s List and Yelp. It may be a good idea to also check the ratings on the Better Business Bureau website, so that you know what kind of service and quality you can expect.

Third, you should check online to see if there are any offers, rebates or incentives being given by your state or local utility for replacing an outdated HVAC system with a newer, more efficient one. In case they are both offering a promotion, you should be able to stack both offers, thus saving yourself a good chunk of money. You should also check with the leading HVAC manufacturers to see if they offer any rebates. If you’re really lucky, you may be able to score a triple discount with the manufacturer, the state and the local utility giving you rebates.  

Finally, ask for at least 3 bids from various contractors before you make the decision. Ask them to factor in any applicable tax rebates and state incentives on efficient appliances into the bid. You might even ask more than 3 companies for quotes, depending on how thorough you want to be. Keep in mind that you may need to wait a few days or weeks in order to get a quote, so unless it’s an emergency, start getting quotes well in advance of when you expect to get the new system.
