How To Tell If My Heating Unit Is Energy Efficient

Having an efficient heating system is important for a variety of reasons, but mainly to keep energy usage to a minimum. The more energy your heating unit uses to heat your home, the more it will reflect on factors such as monthly utility bills. At Anchor Heating & Air, we strive to make home comfort affordable and accessible to everyone in our community. Staying cozy should not come at a cost, which is why our technicians can help keep your unit running efficiently. In this blog, we list ways to identify if your heating unit in Charleston is energy efficient and efficiency benefits.

Why Is Energy Efficiency Important?

If an appliance in your home is energy efficient, it means it uses less energy to operate. Many appliances in your home use more energy than necessary, which drives up utility costs. Heating and cooling units are nearly half of all homeowner’s energy bills, which is why it is important to invest and maintain an efficient heating system. Along with being expensive, less efficient heating and cooling units can be harmful to the environment. Together, we can fight against global issues such as climate change and pollution by minimizing energy usage.

Is My Heating Unit Running Efficiently?

An efficient heating system uses low amounts of energy to operate and has no underlying malfunctions. Below are ways to tell if your heating unit is energy efficient.

  • Check Efficiency Rating
  • Consider The Unit’s Age
  • Compare Utility Bills
  • Check Components Of The Unit

Check Efficiency Rating

Each heating unit has an efficiency rating, which can vary depending on the type your home utilizes. Furnace systems operate by Annual Fuel Utilization Efficiency (AFUE) ratings, while heat pumps operate by Heating Seasonal Performance Factor (HSPF) in the winter. Both can be found in the user manual or on the unit itself.

AFUE ratings measure how efficiently furnace systems convert fuel to heat. Energy can be lost in the process, and the AFUE rating simply identifies how much fuel is actually turning into heat for your home. Due to many furnaces burning natural gas, it is important to utilize and maintain an efficient unit to lower carbon emissions released into the environment. According to the U.S. Department of Energy, high AFUE ratings range between 90% to 98.5%, mid-efficiency is between 80%-83%, and low efficiency is anything under 82%. If your heating system has an 80% efficiency rating, that means 20% of energy is lost in the heating process.

HSPF measures how efficiently a heat pump transfers heat in the winter months. To more accurately measure efficiency, the Department of Energy adjusted the testing procedure and created HSPF2. The HSPF scale ranges from a low 6.8 to a high 13.5. A heat pump rated above 10 is considered a highly efficient heat pump, while 8 to 10 ratings are considered average efficiency. Anything below 8 has low efficiency. In simple terms, the higher the rating, the more efficient and the less energy used.

Consider The Unit’s Age

As heating units age, the system becomes less efficient. Heating systems work all winter long to provide a comfortable environment for your home, which means components will naturally deteriorate over time. Proper maintenance can help keep the unit running efficiently, but eventually the time will come when the system needs to be replaced. Annual heating maintenance is vital to ensuring your will last for many years to come, because the service helps avoid wear and tear of components. Depending on the type of heating system and maintenance given, units can last anywhere between 10-20 years. An Anchor Heating & Air technician can help identify how efficiently your heating system is operating in West Ashley, SC and surrounding areas.

Compare Utility Bills

Have you noticed your utility bills have increased this winter and you aren’t sure why? If this is the case for your home, it could be due to the efficiency of your heating unit. Internal malfunctions and unit obstructions can make the unit use more energy to meet the thermostat setting in your home. We recommend comparing utility bills from previous heating seasons to determine if your system is decreasing in efficiency. Heating maintenance is the best way to increase unit efficiency, because our experienced technicians can identify underlying issues and prevent future problems from arising.

Check Components Of The Unit

While heating maintenance is the best way to ensure an efficient heating unit in Charleston, we recommend homeowners keep up with certain components of their heating system. To personally increase your heating unit’s efficiency, we recommend performing the following maintenance tasks:

  • Seal Air Leaks. Air can easily be lost through cracks in windows and doors, so we recommend caulking or weather stripping to seal air leaks.
  • Insulate Your Home. Due to warm air rising, air can escape through your attic and increase energy loss. We recommend adding insulation to attics, basements, crawlspaces, and other unheated areas.
  • Change Air Filters Every 90 Days. Maintaining a clean air filter is vital to heating unit efficiency. A dirty air filter causes the unit to use more energy to push air through filter pores.
  • Have Ductwork Inspected. As heat is distributed into ductwork, it can be lost through air leaks and quickly lose energy.
  • Install A Smart Thermostat. The lower your thermostat in the winter, the more you will save. Smart thermostats can lower thermostat settings when your home is vacant or when residents are sleeping to save energy.

All of these maintenance tasks help your heating unit run efficiently. If the unit is obstructed, it uses more energy to operate and increases heating costs.

Benefits Of An Efficient Heating Unit

An efficient heating unit can present many benefits for your home in Charleston. Below are 5 of the many advantages of prioritizing heating system efficiency.

  • Low Heating Costs
  • Improved Home Comfort
  • Environmental Benefits
  • Longer Unit Lifespan
  • Less Maintenance

While we await warmer weather, we are here to keep your home cozy and comfortable this winter. It is never too late to lower energy usage and schedule heating maintenance in Mount Pleasant, South Carolina! Give us a call to have an Anchor Heating & Air technician perform a thorough maintenance check on your heating unit and benefit your home!

I would like to give a shout out to Anchor Heating & Cooling for their awesome service. I would like to recognize Jordan Musselman, my maintenance tech, who did a fantastic job. He was very professional, patient and thorough in his service and review of my HVAC system.I cannot say enough good things about this company.. They are amazing, efficient , thorough, and very very customer oriented as well as reasonable in pricing.Thank you to all for a job Well done.Your services are greatly appreciated.

I have lived in my neighborhood for over 20yrs and have used a number of HVAC companies over these years. Some were ok and got the job done and some were not good at all... I then lucked out and found a great individual who was trustworthy and dependable for about 6 years but then moved away. I purchased a new unit and utilized several different companies for my yearly maintenance and cleaning. I wanted to find a reputable HVAC company that operated with integrity and were not going to upsell me on something with every visit. After talking with some friends, researching our FB neighborhood pages, Anchor kept coming up for recommendations. I read their reviews online and they confirmed what I was looking for. Rick came out about a month ago for a service call to check over my unit to ensure it was running efficiently. Jonathan came out today for the first maintenance visit. Both techs were courteous, knowledgeable and transparent with everything. I can tell that Anchor is doing something right by attracting good people who want to be there to do quality work without pressure to sell things that are not needed. Both were genuine in their demeanor and I enjoyed talking with both of them. Highly recommend Anchor Heating and Air and glad I found them.
We didn't end up using Anchor for a new HVAC system but it was a close 2nd choice. Jeremy came out and gave us a estimate. He was very professional and thorough and took the time to explain the different options and saved us from getting possibly unnecessary expensive new ductwork. He followed up after to the appointment to answer any questions and was just great. If you are thinking of getting an estimate/service I would highly recommend them. When we have to replace our 2nd HVAC I'll definitely call them again.

After reaching out to Anchor Heating and Air LLC to get a second opinion on a previously assumed issue, their technician Mr. Hardee was extremely helpful with diagnosing the actual cause, for why my house was not properly cooling and the issues my family and I were facing. Every question or concern that I asked about, they had an answer. This is a company I will suggest to my neighbors, family and friends.

Celia S
Quick and easy!
Steve H.
The team at Anchor Heating and Air was very clear in their communication and were very timely on their response to our needs. This has got to be one of the busiest times of the year in their industry. Their quick and knowledgeable response was much appreciated. They had the parts on their truck and had me up and running in no time. Doug showed up when expected, represented the company in a professional manner, and looked good in his Anchor Heating and Air attire. Professionalism is the best way to describe my entire experience.

Chad C.
Would definitely recommend and use again.
Alexandra E.
Brian was great! We got several opinions on our HVAC unit and got vastly differing recommendations from each company with little to no explanation of the issues. Brian was very thorough in his inspections and saved us literally thousands of dollars. Of course eventually need to have our unit replaced but as of now, only maintenance was necessary. I wouldn’t trust another company right now. These guys really put the customer first. I also found that their maintenance plan seemed to be the fairest so we’re happy to to be part of the “captains club” at Anchor!
Jim Y.
Megan C.
Lori C.
I am so pleased with Anchor! Woke up this morning to a hot house! Tried calling several companies and didn’t get any response. I reached out to my Facebook friends for a recommendation and many said Anchor. Stephanie even reached out to me herself and said they would get to me today. Technician Brian Hardee showed up and quickly diagnosed our problem. He explained everything to us and replaced our capacitor. He was a great technician and very thorough. I am on my way to a cool home again! I joined the membership club to get service maintenance and a discount on the part! I will definitely recommend Anchor Heating and Air!
Lee C.
Service tech Jeffrey was excellent! Showed up on time. Good communication and very knowledgeable. Very impressive!

Anchor Is A++ from the moment you call for service. Ella was friendly and quickly got us set up for an appointment the day our A/C went out. We received texts to let us know what technician would be arriving, and when to expect him. Rick was on time, friendly, and efficiently diagnosed our issues. He had us cooling off in no time on a busy holiday weekend. I highly recommend Anchor Heating and Air!!!
Jessica D.

Their arrival time was prompt and communication is key and this company communicates very well with the client and among their team.

They also have a membership program that’s worth signing up for and does come with some savings on maintenance. Give them a call!
Kyle R.
Jeff Hoppe was great. He helped me figure out exactly what problem I was having with my system and gave me some great advice on thermostats. Didn’t try to push any unnecessary purchases/replacements just diagnosed and helped me fix what was wrong. Great experience and would highly recommend

We had Jordan come out to check our AC, as it was acting up. He was courteous, on-time, personable, professional, knowledgeable, and so friendly. We enjoyed meeting and interacting with him. As it turns out, our crusty old unit needs replacement, and Amanda came out to build an estimate. She too, was very professional, knowledgeable, sensitive to our needs, a great listener, easy to talk with, and very personable - I want to be friends in real life! 😂 We haven't made a plan for our AC yet, but wow, this company hires some really amazing people, which is a major green flag. Two separate people recommended Anchor to us, and I'm so glad they did. Thanks y'all!

Jeffrey came to inspect our extremely outdated unit, gave me a full explanation on everything including showing pictures and videos that he took and recommendations on how to move forward. Super professional and kind. Thanks!

I highly recommend Anchor Heating and Air. We had our regularly scheduled service maintenance with Jonathan. He was very knowledgeable and courteous. Showed me pics and gave me some recommendations. He did a thorough maintenance. We’ve had our system serviced before but it was not this detailed. We also had tech Jack and Ryan come and clean our dryer vent. Both of them were also highly trained and knowledgeable. They explained the process and showed before and after pics. Very impressing from scheduling , communication before and after the visits and all the above!! I can’t say enough good things about this company! Thank you Anchor Heating and Air.

Ruby G.
We had an excellent experience with Anchor. Had a broken motor and an 89 degree house. Jordan and Jeffrey came out that day, gave us a full explanation, and provided multiple quotes. They were polite, super informative, and made us feel very comfortable with our decision. They were back the next day and fixed our AC with ease. Very thankful to Anchor and their whole team.

Joel M.
Great service and very respectful! Highly recommended.
Jeanette K.
The team at Anchor Heating & Air are the best. Stephanie set us up with the soonest available appointment. Rick arrived at the specified time. Rick was personable, professional, very thorough and though the repair turned out to be extensive, Anchor offered a window AC unit for nighttime comfort. While the part was being acquired for our repair, Jack delivered the AC unit. Jack was equally personable & professional. Then there is Alyssa who called with our estimate & scheduled the final repair. Alyssa is equally as wonderful as Rick & Jack, which brings us back to Rick, who arrived this morning with the part, completed the repair and we are now sitting in the comfort of our air conditioned home. This wonderful team of people are the first company that we’ve worked with in this capacity who are truly empathetic, truly understand how their clients feel and do everything possible to ensure the best experience. It’s not what they do, it’s who they are. We are extremely grateful!
chris R.
They are amazing to deal with. Easy scheduling showed up on time. Did amazing work excellent communication and I personally think they saved my house from burning down. They came and inspected my dryer vent. Needless to say it was very very bad. Check out the before and after photos I would definitely recommend them for all your HVAC ductwork needs
Halcyon home S.
Very helpful and knowledgeable. Overall great experience.
Al M.
Great customer service, professional and polite!
Ryan W.
Unbelievable experience! My AC stopped working last week. I left a message last Wednesday night and was up and running before noon on Thursday. Outstanding! Alyssa called me first thing in the morning to get me on the schedule and Doug was there before 10am to fix the problem. He was absolutely fantastic and took care of everything. Thank you guys so much for taking care of me. 10/10! I highly recommend Anchor for AC help.
Chad H.
Showed up on time. Very professional. Very knowledgeable. Definitely would use again.

Marc O.
5 stars for Brandon: he did a first-rate job for our annual HVAC service. He was knowledgeable, courteous, and a pleasure to deal with.
Quero D.
It would be good to not receive multiple review requests until you guys do the actual service. I have received 4 requests to provide 5 star reviews but you are not scheduled to do the service until next week. However, once the service guy, Ron turned up he was great, professional, knowledgeable and explained everything he was doing and made recommendations to keep the units in good shape - thank you Ron.
Stuart B.
Appreciate the friendliness and professionalism of Jeremy Lee who came out to provide an estimate for a replacement HVAC system. Jeremy spoke highly of Anchor and the friendliness of his co-workers. It would have been great to do business with the folks at Anchor just based on what Jeremy thought of his colleagues. I received a call from a co-owner, David who reached out to me to find out what I was thinking. Great family business and when circumstances allow, I will reach out to them again.
G R.
They are on-time professionals who know what they're doing.

Brandon and crew were excellent with our replacement HVAC install! Very professional and went above and beyond (on a holiday weekend) after realizing we needed an additional part to complete the install. The service was impeccable and we’re so glad we went with Anchor! Highly recommend this company for any HVAC needs!
Tracy M.
I couldn’t be happier with the service provided by Rick from Anchor Heating & Air. From his initial greeting to the time he left after performing maintenance on our 5 units, he was everything you’d want a service provider to be. Not only did he perform the work with care and expertise, he explained what & why I needed to replace a few parts. He included photos he had taken inside my HVAC units to compare with industry standards to show the disparity.He left my home in the same order he found it and assured me he’d return ASAP with new parts. In under a week, the parts are in and I’m scheduled to have them I stalled.I welcome Rick back into my home anytime to continue to service our HVAC units. He is a wonderful asset to Anchor Heating & Air.
