Frequently Asked Questions

01.
How long does a Water Heater last for?

A residential water heater will likely last for 8-12 years. However, with the proper water quality/treatment, and proper maintenance you could have the same water heater for 20 years!

02.
What can I do to prevent my drains from backing up?

Keep the usage of your drains to what should go down them. Don’t flush anything except toilet paper down the drain- and the thinner the ply the better. Scrape your dinner plates into the trash before running it down your kitchen sink. Install hair catches over the drains in your bathroom sinks/showers. Also, a great product we fully endorse is BIO-CLEAN to use as a preventative treatment to help keep drains open.

03.
Why does my water taste/smell funny?

There are a lot of causes for this. It could be the magnesium anode rod in your water heater working over-time creating a sulfur like smell. It could be a certain mineral in your water coming from your well. Whenever there is any question or concern about the safety of your drinking water, reach out to us so we can gather a sample and have it tested. After doing so we can present you with options to properly resolve the issues.

04.
How long will my sump pump last for?

This can range wildly depending on the type of sump pump you have and usage. Most warranties are based on what the pump is rated at for revolutions over its lifetime before failure rate. Some big box stores have sump pumps only rated at 100,000 revolutions whereas contractor grade sump pumps can be rated as high as 2,000,000 revolutions. “You get what you pay for” applies here. If you have a sump pump that runs often you should consider evaluating and upgrading the pump while also installing some sort of back up system or at a minimum an alarm system to alert, you to flooding.

05.
If I see a leak- what is the first thing I should do?

Shut off your water as quickly as possible. Find the water meter that supplies your home or business and shut the water off there. Once you’ve stopped the water flowing, you can look for a branch shut off valve to see if you can isolate just that line. Once you’ve addressed the immediate concern of the water leak, reach out to your plumbing contractor to repair the leak.

Heating Questions

01.
How long should my furnace last?

This question mostly depends on the owner. Without proper maintenance, the life expectancy of the unit rapidly declines. In addition, newer furnace models have more technology and are better engineered, and as a result, last longer. So, a modern, well-maintained furnace has the potential to last upwards of twenty-five years. While at the same time, a neglected or poorly maintained furnace will probably only last around eight to ten. It’s all about being proactive instead of reactive.

02.
What does AFUE mean?

Annual Fuel Utilization Efficiency: Listed as a percentage, this is a direct ratio of fuel pumped into the furnace and usable heat created from the fuel. For example, Our Rheem Endeavor® Line Classic® Series is 95% AFUE, meaning that, for every 100 BTUs of fuel the furnace uses, 95 BTUs enter your home. Clearly, the higher the AFUE, the better.

03.
What is a BTU?

BTU stands for British Thermal Unit. It equates to the amount of heat and energy required to raise the temperature of one pound of water one degree Fahrenheit. In terms of HVAC, a 12,000 BTU furnace is capable of creating 12,000 BTUs of heat per hour.

04.
What is HSPF?

Specifically, HSPF measures a heat pump’s estimated heating output for the spring and fall. Once again, the important thing to note is that a higher score on the HSPF scale yields a more efficient Heat Pump.

05.
What size furnace will I need?

This is a very difficult question that requires a complex answer. There are numerous factors that determine which size unit will operate best in your home. The age, size, and ductwork of your home all play a role in sizing your unit. For best results, schedule a FREE QUOTE with Rolls Mechanical to receive the most accurate answer based on a proper load calculation we perform prior to coming to your home.

CAUTION: A larger unit does not necessarily mean a more effective unit. You need a furnace or air conditioner appropriately sized for your home to heat and cool effectively and efficiently.

06.
What efficiency should my furnace be?

In short, your furnace should be as efficient as possible. We recommend at least 92% efficiency. While 80% AFUE units may be slightly less expensive, the money you “save” up front will be negated by higher operating costs within a few years. Throughout the life of a furnace, the lower AFUE models will actually end up costing you more in the long run.

07.
Who makes the most reliable furnaces and air conditioners?

In all honesty, every company that comes to your home is going to tell you that the HVAC supplier they carry is the absolute best. But according to consumer reports and Heating, Air Conditioning, and Refrigeration News, the contractor’s expertise and proficiency with the brands they work with are far more important than the units they install. Here at Rolls Mechanical, we prefer Rheem® furnaces and air conditioners,Based on the Quality construction, simplicity and Customer Satisfaction.

Cooling Questions

01.
How long should my air conditioner last?

That mostly depends on you as the owner. Without proper maintenance, the life expectancy of the unit rapidly declines. In addition, newer air conditioner models have a more sophisticated construction, and as a result, tend to last longer. So a modern, well-maintained air conditioner has the potential to last upwards of twenty-five years, while a poorly maintained air conditioner will probably only last around ten. It’s all about being proactive instead of reactive.

02.
What does SEER mean?

SEER stands for Seasonal Energy Efficiency Rating. It is calculated by dividing the typical cooling output of an average season by the total energy input during the same amount of time. The important thing to understand about SEER ratings is that a higher rating equates to a more efficient system.

03.
What does EER mean?

The EER, or Energy Efficiency Ratio of a cooling system, indicates how effectively the air conditioner will operate at a specific outside temperature (usually at 90 degrees). Once again, the higher the rating, the more efficient the system.

04.
What is the difference between EER and SEER?

The SEER (Seasonal Energy Efficiency Ratio) measures how efficiently a unit will operate over the course of an entire season as opposed to under specific circumstances like temperature.

05.
What is a BTU?

BTU stands for British Thermal Unit. It equates to the amount of heat and energy required to lower the temperature of one pound of water one degree Fahrenheit. In terms of HVAC, a 10,000 BTU air conditioner is capable of removing 10,000 BTUs of heat per hour.

06.
What is HSPF?

Specifically, HSPF measures a heat pump’s estimated heating output for the spring and fall. Once again, the important thing to note is that a higher score on the HSPF scale yields a more efficient Heat Pump.

07.
What size air conditioner will I need?

This is a complicated question that requires a complicated answer. There are numerous factors that determine which size unit will operate best in your home.

For best result, schedule a FREE evaluation with Four Seasons Heating and Air Conditioning to receive the most accurate answer.

08.
What efficiency should my air conditioner be?

In short, your air conditioner should be as efficient as possible. We recommend at least a 16 SEER unit. The money you “save” on up-front pricing will be negated by higher operating costs within a few years, and throughout the life of an air conditioner, the lower SEER models will actually end up costing you more.

Energy Efficiency Questions

01.
What efficiency should my furnace be?

In short, your furnace should be as efficient as possible. We recommend at least 92% efficiency. While 80% AFUE units are available, the money you “save” on up-front pricing will be negated by higher operating costs within a few years, and throughout the life of a furnace, the lower AFUE models will actually end up costing you more.

02.
How much energy does a Compact Fluorescent Lightbulb (CFL) save?

A lot. As opposed to incandescent (the standard bulb you are familiar with) a CFL will cost approximately 75% less in energy costs and last ten times longer.

03.
What are some great ways to save energy on heating and cooling costs?

Regular maintenance ensures that your air conditioner or furnace will operate at peak efficiency. It is recommended to schedule a Clean and Check before each heating and cooling season.

In addition, a more efficient unit will cost less to operate. Every year, increasingly more efficient units are designed and developed by Rheem. If your furnace or air conditioner is roughly ten years old, today there are a slew of vastly more efficient units available from Rolls Mechanical.

For a no-cost option to lowering your bills, you can simply raise/lower your thermostat. For every 2 degrees you raise it (in the summer) or lower it (in the winter), you cut energy costs by 10%.

04.
How does a programmable thermostat save energy?

People are forgetful. We don’t need to heat or cool the home while we are at work or on vacation, but it is very easy to forget when rushing out the door at 7 AM to turn off the HVAC unit. The programmable thermostat prevents human error from entering the equation. Program your schedule into the thermostat and it will always remember to turn off the furnace/air conditioner when you’re not around to use it.

Insulation Questions

01.
What is an R-Value?

Using insulation with an R-Value of 60 will make a significant difference in your utility bills. According to EnergyStar, based on Michigan’s location in 3 different temperature zones as well as an average of the coldest-month temperatures, an R-rating between 49-60 is highly recommended.

02.
How do I determine if I have enough insulation?

The recommended R-Value generally equates to 14 inches of attic insulation. For a more specific measurement, contact Rolls Mechanical.

03.
Why do you only use blown-in insulation?

In short, because it is vastly superior to the big pink sheets we are all familiar with. It is easier, faster, and less impactful to your home to install and will not degrade over time. In addition, it provides a tighter fit to the walls and attic which keeps out moisture and prevents the growth of pests and mold. Better yet, it is made from recyclable materials.

04.
Can blown-in insulation be applied around electrical wiring?

Yes. If there is wiring in your attic or walls, it will not disrupt energy efficiency or the wires in question.

05.
Why do you remove the old insulation when installing a new layer?

This generally occurs when the client did not previously have blown-in insulation. Other forms of insulation degrade over time. While it may seem productive and cost-effective to simply spray onto the old layer, this will yield.

Air Quality Questions

01.
What is considered good IAQ?

Good indoor air quality involves a comfortable level of temperature and humidity, a sufficient amount of fresh outdoor air, and a safe level of pollutants from inside and outside of the building or home.

02.
Do I need a humidifier?

Yes. A humidifier will eliminate dry air problems in the home and ensure the most comfortable atmosphere for you and your family. With fresh water drains to prevent mildew formation and calcium/rust-resistant designs, the humidifiers of the 21st century are leagues beyond older models.

03.
How often should I have my ducts cleaned?

Rolls Mechanical recommends getting your ducts cleaned every 10-13 years or if you have had any major construction and or remodels done.

04.
How does poor indoor air quality affect my health?

Indoor air quality can affect your health in a variety of ways. Irritation in the eyes, nose, and/or throat is common. Headaches, dizziness, fatigue, and other symptoms akin to allergies are also common. These effects are usually short-term and are alleviated once you have exited the building. However, in severe cases, asthma, hypersensitivity pneumonitis, and humidifier fever have also been reported.

05.
What are some common indoor air pollutants that I should be aware of?

There are many things in your home that can negatively affect your air quality. Here are just a few of them.

  • Radon: Have your home tested for radon levels. If the levels are too high, professionals will need to be contacted to remove the radon from your home
  • Tobacco Smoke: Don’t smoke and ask others to smoke outside.
  • Pollen/Dander/Mold: Keep your ducts clean, and make sure you have a fresh filter installed in your furnace every month.
  • Paints, Cleaners, and Artificial Scents: Make sure you provide adequate ventilation when using these products.
