A gas furnace is an effective and reliable way to heat your home. Because of the cost of natural gas as compared to electricity, it tends to be the more affordable option, as well. And as technology has improved, gas furnace efficiency has increased significantly. But what people sometimes wonder is just how safe it is to use a gas-burning furnace to heat their home.

On the whole, the answer is a simple yes. Driving a car, an everyday thing you might not consider risky, is thousands of times more dangerous than having a gas furnace. The improvements in technology that have allowed efficiency to go up have also improved safety. And as long as you have working carbon monoxide detectors and make sure your furnace receives routine maintenance, it’s perfectly safe. If you want to know exactly how to best ensure your safety when you have a gas furnace, though, you should learn about the heat exchanger.

Don’t Let Your Heater Scare You: Heed These 5 Signs of Disrepair

Monday, December 17th, 2018

woman-covering-earsWhen winter rolls around, the last thing you want to do is worry that your heating system can break down at any moment, right? Of course, the best way to avoid this is by scheduling routine maintenance for your heater. During this service, our technicians comprehensively inspect and clean your system, noting any signs of disrepair and alerting you to them.

If you skip maintenance, or if you haven’t had maintenance done yet this year, then you’re at a higher risk for sudden system breakdowns and higher repair costs. But the sooner you repair your system, the lower your monthly bills will likely be. So, spotting signs of a heater in disrepair is a good idea. How do you do so?

Benefits of Gas Furnaces

Friday, December 21st, 2012
  • Indoor warmth any time it is required.
  • Energy efficiency – The efficiency of a furnace can be determined by its AFUE – or Annual Fuel Utilization Efficiency. The minimum efficiency level for furnaces currently manufactured in the U.S. is 80% AFUE. A rating of “80% AFUE” means that for every dollar you spend heating your home; 80 cents are actually applied to the generation of warmth. Compared to many of the 60% AFUE furnaces in older homes, 80% AFUE furnaces are a significant improvement. However, for enhanced energy efficiency, you may wish to consider a 95+% AFUE furnace, such as Amana’s line of 96% AFUE Furnaces.
  • Cleaner air – As your HVAC system draws air out of various rooms in the house through return air ducts, the air is pulled through an air filter, which removes airborne particles such as dust and lint. Sophisticated filters may remove microscopic pollutants, as well. The filtered air is then routed to air supply duct-work that carries it back to rooms. Whenever the HVAC system is running, this cycle repeats continually, constantly filtering and cleaning the air in your home.

This cleaning process improves with the installation of a variable-speed furnace. Variable-speed furnaces use variable-speed blowers, which shift between several speeds. These furnaces will run longer at a low speed, which causes them to filter the indoor air more frequently.
And remember – because the furnace plays an important role in the operation of the air conditioner, its variable-speed blower helps maintain both a consistent indoor temperature and improved air quality year-round.

5 Reasons That NOW is the Time to Replace Your Inefficient HVAC System

Wednesday, November 14th, 2012

1. Lowering Your Utility Bills
Whether you realize it or not, your current furnace could be costing you more than it should in heating bills. If your furnace is 15-20 years old, it’s probably not heating your home as efficiently as the newer models with higher AFUE ratings. Even if your heating system has been replaced within the last ten years, the technology has advanced enough to consider an upgrade.
2. Fewer Repairs
Repair costs can add up if you are constantly repairing your furnace. Routine maintenance for your furnace can help reduce the need for repairs, but as furnaces age, they tend to need more repairs and replacement parts. If you need frequent repairs for your furnace, it may be time to replace it with a newer one.
3. More Consistent Heat
While maintaining consistent temperatures throughout your home involves several factors, such as insulation and thermostat control, your furnace could also be the reason you aren’t getting enough heat to all parts of the house. If some rooms are colder than others, or if your heating bills have recently gone up, it may be time for a furnace replacement.
4. Safety
There’s higher potential for safety concerns with older or poorly maintained furnaces. In addition to fire hazards, carbon monoxide poisoning is another serious threat. When the heat exchanger stops working because it’s corroded or faulty, carbon monoxide can leak into the home. If you’ve had your furnace for more than 20 years, it could create safety hazards that you may be unaware of.
5. 25 Months 0% Interest with 25 Equal Monthly Payments
We know some of you are waiting for a great opportunity to switch from your old inefficient heating and air conditioning system. For a limited time, we have 0% interest for 25 months (with approved credit). 25 equal monthly payments required. No lengthy applications and approvals within minutes!
