As temperatures rise, many homeowners are considering upgrading their heating, ventilation, and air conditioning (HVAC) systems. Replacing your home’s heating or cooling equipment can cost thousands of dollars, making it a significant investment.

The Importance of Professional Installation

When you need to upgrade your system, choosing the right company is crucial. How well a new system performs and its overall cost depend heavily on proper design and installation. Delaware Valley Consumers’ Checkbook surveys of local consumers revealed dozens of excellent HVAC services, but also identified contractors with poor ratings.

Through a special arrangement, Inquirer readers can access Checkbook’s ratings of local HVAC services for quality and price free of charge until May 5.

Understanding Energy Efficiency Ratings

If you’re in the market for new HVAC equipment, you’ll encounter various options with different energy efficiency capabilities. Familiarizing yourself with energy-rating terminology will help you make an informed decision.

Consider a heat pump instead of a traditional central air conditioner. These devices function as both air conditioners and heaters, offering exceptional energy efficiency and quiet operation. They can also reduce your reliance on furnaces.

Cost vs. Efficiency

Energy-efficient models generally cost more than basic ones. While environmental concerns often motivate homeowners to choose higher-efficiency options, lower power bills and utility company rebates can provide additional financial benefits. In many areas, the savings will quickly offset the initial higher cost.

Most HVAC contractors won’t provide precise calculations of utility bill savings. However, they can estimate the percentage you’ll save with different types and models of equipment, allowing you to calculate potential savings based on your current energy bills.

Options for Targeted Cooling & Heating

If you’re adding an addition or seeking to improve heating or cooling in a specific area, such as a basement or upper floor, a ductless mini-split heat pump is a good option. These highly efficient units allow for independent temperature control in individual spaces.

Don't Forget Home Improvements

Before investing in new HVAC equipment, address potential energy waste. Identifying and sealing leaks and improving insulation will provide the greatest return on your energy-conservation efforts. Many of these improvements are inexpensive and can significantly reduce your utility bills.

Proper Sizing is Key

Ensure the equipment you purchase is the correct size for your home. An undersized unit won’t adequately heat or cool the space, while an oversized unit will cost more, cycle on and off frequently, and have a shorter lifespan.

Capacity, measured in British thermal units (BTU), determines the size of heating and cooling units. For furnaces and heat pumps, capacity is the amount of heat generated. For air conditioners, it’s the amount of heat removed. Capacity is often described in “tons,” where one ton equals 12,000 BTU.

If you’ve expanded your home or finished previously unconditioned space, companies should perform a load calculation to determine the appropriate equipment size.

Getting Competitive Bids

Obtaining competitive bids from several contractors will save you money. Price differences for the same equipment and work can exceed $1,500 for large installations, and even smaller jobs show considerable price variation. Invite reputable companies to provide written proposals.

Ask each contractor about the need for multiple heating or cooling systems and thermostats, and the benefits of features like variable-speed blowers. If adding a new system, inquire about ductwork routing, condenser and blower mounting, and access for maintenance.

Payment & Financing

Settle the payment with a credit card to provide dispute resolution options if you’re dissatisfied with the work. Many homeowners finance installations through third parties, often at high interest rates. Carefully review all repayment terms before signing any loan paperwork.

Be cautious of HVAC companies offering zero-interest loans, as they may include hefty deferred-interest fees. Equipment leases can also be unfavorable contracts.
