At Heritage, our technicians can help you determine whether or not it is in your best interest to replace your gas furnace.

HVAC problems solved in 2016

A gas furnace replacement or installation is about much more than removing an old furnace and replacing it with something new. It requires a skilled specialist who is trained to:

  • Conduct a thorough, room-by-room analysis of your heating system and your home’s thermal design
  • Discuss any shortcomings with your current system and talk about ways to improve comfort levels throughout your home
  • Use information from the audit and the insights you’ve provided to design a range of potential solutions
  • Explain your options and answer all questions to help you make the most informed decision

This friendly, in-home consultation process enables our professional furnace installation specialists to help you fully understand the process and to pick out a gas furnace replacement solution that is best suited to your needs.

If you do decide to get a replacement, our specialists will walk you through all of your options when it comes to choosing a new gas furnace. We want to make sure that you get a new system that meets all of your requirements. We will outline the prices of equipment and labor, so that you know all of the costs associated with your new installation.

When our technicians come to install your replacement, they are always mindful of you and your home. First, they always enter with booties and clean up their workspace, so that you are not left with dirt and debris in your home. Second, they are always transparent about their work. At Heritage, we believe it is important to educate our customers.

Because we believe part of our job is to educate homeowners about their heating systems, listed below are some of the signs your gas furnace may need some attention, along with the answers to some frequently asked questions.

Signs You May Need a New Gas Furnace

Rising energy bills: If your gas furnace is burning more fuel in order to produce the same level of comfort, this can be a sign that it is operating less efficiently, perhaps due to a range of potential system issues that you’ll want to have checked out.

Strange noises: Are you noticing any pinging or popping, banging or rattling, squealing or grinding? Such unexplained noises, as well as strange smells or smoke, should serve as a red flag that your forced hot air gas furnace needs some attention.

Multiple repairs: Have you spent money to have your gas furnace repaired more than once in the last couple of years? As they age, it’s not uncommon for furnaces — much like cars — to have one part fail, followed by another, then another. This can mean it’s time to weigh those continuing repair costs against the value of a new system.

Your comfort level: Have you been spending more time at the thermostat trying to keep your home, or specific areas within it, warm and comfortable? Have you begun to notice the air in your house seeming dry or dusty, stuffy or stale? It’s a good idea to make a note of these and any other problematic conditions to discuss them with your heating technician.

It’s getting old: Gas furnace life expectancy can vary greatly, of course. Forced hot air systems that are professionally installed and well-maintained can last significantly longer than those that are not. Most forced hot air systems should last for at least 15 years. Depending on the age of your system, it may be wise to start planning now to avoid having to deal with an emergency situation.

Frequently Asked Questions

If I need a new gas furnace, what’s the first step?

When we’re talking about a gas furnace installation, it’s likely that a service technician has already visited your home, diagnosed the condition of your system and begun the conversation about possible repair options versus replacement. At this point, it makes sense to schedule an in-home consultation with an installation specialist who conducts a comprehensive thermal audit of every room in your home, factoring in window placement, the direction of the sun, ductwork and outlets, and more. 

Not every company does an in-home consultation, but it is an important step for many reasons. For one, many of today’s home heating systems are either undersized or oversized, poorly configured or poorly installed. Our thorough review helps pinpoint and resolve these issues.

How does the installation specialist come up with his recommendations?

It all starts with our comprehensive thermal audit of your home and our conversation with you about opportunities to maximize comfort levels throughout your entire home. Your installation specialist will listen closely to your needs and concerns, and use data and observations gathered during the thermal audit to design a range of options.

At Heritage, our experienced installation specialists are trained to:

  • Take the time to understand exactly what outcomes you are looking to achieve with your new system
  • Make sure your existing piping and ductwork are properly designed to deliver optimal comfort and efficiency
  • Be transparent about your options and pricing, always providing multiple system options and never pressuring you into picking a particular solution

What if I want to get a second opinion or compare competing quotes?

No problem. We’re so confident about being able to earn your business by providing the highest quality customer service and workmanship that we encourage customers to compare our proposed solutions with those offered by the competition. 

Sometimes a competitor may quote a lower price to get your heat flowing, but a closer look reveals that the competing quote is actually for an inferior solution. We request the opportunity to discuss competing quotes with you to help ensure that your decision is truly based on an “apples to apples” comparison and to talk to you about our price-match guarantee. 

What are my payment options?

A new heating system represents a significant investment in your home. And while some customers may write a check or use a credit card; for others, solid financing options are imperative. Need a solution that involves no payments and no interest for 12 months? We offer a range of such options — all designed to make payment as convenient and painless as possible. Revisiting the design specifications of your optimal heating system solution can also be a way to realize savings.

In addition, Heritage makes it a priority to help customers reduce overall costs by taking advantage of utility and manufacturer rebates or tax incentives for upgrading to more efficient systems, even providing the applicable forms and helping to fill them out.

How solid are your warranties and guarantees?

Our longstanding relationships with the leading manufacturers enable us to offer the most comprehensive warranty protections available. Plus, we’re happy to spend time explaining them. With Heritage, you’ll always know you are working with a company that has your back if something ever goes wrong. That’s peace of mind.

How do I know the installation specialist is really looking after my best interests?

The responsibility of being invited into your home to maintain, repair or replace your gas furnace heating system is one that we take extremely seriously. We thoroughly vet and train every employee to approach each job with the utmost professionalism, courteousness and care. You can also be certain that our technicians and installation specialists will be friendly, straightforward and helpful when it comes to explaining their findings so you can fully understand the issue and get honest answers to all of your questions.
