Furnace Replacement

Sometimes a repair is not sufficient to fix your furnace. Sometimes a new furnace is the most cost effective and energy efficient way to go. We will always be honest with you about a possible furnace replacement. We value our time and your money, we don’t want to perform repairs or service on an appliance that is need of replacement.

If you do need a furnace replacement, we know how overwhelming it can be. Here are some of the frequently asked questions about furnaces that we get from some of our Hudson residents:

What are the different types of furnaces?

Single Stage – This type of furnace has only one stage of operation. It can either be turned on or turned off.

Two Stage – This type of furnace has two settings, full and half speed. This is a more efficient way to heat and provides for better comfort because it can move the air at a slower pace.

Variable Stage or Modulating – This kind of furnace modulates the speed and heat output based on the temperature outside and the desired comfort level. This furnace only works as much as you need it, this makes it the most energy efficient type of furnaces.

What is AFUE?

Annualized Fuel Utilization Efficiency
A measure of furnace heating efficiency. The higher the AFUE, the more efficient the furnace.

What size furnace do I need?

We can calculate the correct size furnace for your home. The number of BTUs or British Thermal Units, needed to heat your home is dependent on a number of variables. Contrary to what you might think, a bigger furnace may not necessarily mean more heating power for your home. Call us at 978-562-5309 or contact us online and we can set up an appointment to calculate the size furnace you might need.


We don’t just service furnaces. Many of our Hudson and surrounding area customers have heat pumps. Heat pumps are an energy efficient and environmentally friendly way to heat your home. If you want a heat pump installed or serviced or need repairs for your current one Chaves Heating and Air Conditioning, Inc. is here for you.

What kind of heat pump do you have?

A heat pump is a device that transfers heat from one place to another, from in to out or from out to in. It collects energy from a source and then transfers that energy into heat for your home. There are 3 basic forms of heat pump available:

Air Source
An air source heat pump collects energy from the air through a series of coils and transfers it into heat.

Water Source
A water source heat pump collects energy from water by running a series of pipes underwater and then transfers that into heat for your home.

A geothermal heat pump, also known as a ground source heat pump collects energy from the earth through a series of coils and transfers that energy into heat.


Many of our Hudson customers have boilers in their homes and workplaces. Boilers are a complex appliance with a fairly basic purpose, to heat water and distribute it through your home. But just because it seems simple doesn’t mean its easy to fix.

The key components in your boiler are a burner, combustion chamber, heat exchanger and controls. The controls regulate ignitions, burner firing rate, fuel supply, air supply, exhaust draft, water temperature, steam pressure and boiler pressure. The water is heated inside the boiler and is pumped through pipes and delivered to the radiators around your home or building.

There are a number of places where things can go wrong in a boiler, it is best to have a certified professional diagnose the problem for you.

Again, job well done and I would both refer and call on you again.

“My entire experiece with Chaves was excellent. We had problem with fernace in on cold morning and we called. They called back in a few hours and sent someone to examine the problem, they told us how to get by exsiting problems and backup options. On second day, they sent someone to evaluate the situation in details. the technician suggested to replace this 25 years old furnace with a more efficient one. Chaves provided a quotation within one day. We decided to move forward and installed the wonderful system within a few days. We are very happy about the price/performance of our new firnace, the process of the installation, communication thru the process, and friendly services.”

– Tsai J.

“Mike and Al replaced my furnace, installed a new central ac system, and also installed a new humidifier. These guys did an excellent job – my furnace was original to my home built in the 70's so it was somewhat of a tricky install – and they did an amazing job in a very timely fashion.
I highly recommend these guys!”

– Rob S.

“The team was prompt, professional, and very easy to work with. They answered all my questions, eased any concerns, and installed the unit to meet my expectations and preferences. Will definitely be using Chaves again.”

– Ryan L.

“Service was fast, clean and efficient. I was pleasantly surprised at how quickly I was able to get an installation appointment. The two technicians from Chaves (I believe one was TJ, and I missed the other's name) were friendly, professional, worked faster and cleaner than expected, and were very respectful of my home. I'd highly recommend your service to others.”

– Adam G.

“The complete replacement of two HVAC systems went very smoothly.
