What is the proper indoor humidity level?

Humidity plays a big role in the quality of your indoor air, and too much or too little can have a negative impact on your health and home. For best results, it is recommended to aim for a relative indoor humidity level of between 45 and 55% during the summer months and 25 to 35% during the winter.

An environment that is too humid can encourage the growth of mold and mildew, and in the summer months, your air conditioner and dehumidifier can help to reduce the amount of moisture in your indoor air.

If the humidity in your home is too low, it may cause dry skin, sore throats, and allow viruses and other airborne toxins to thrive. A humidifier can help to raise the humidity to acceptable levels and restore comfort and air quality throughout the heating season.

How can I lower my energy bills?

Increase the energy efficiency of your home with these tips:

  • Seal air leaks around doors and windows, and have your ductwork inspected to prevent the loss of conditioned air.
  • Install a programmable thermostat to automatically regulate the temperature of your home based on your family’s schedule.
  • Replace incandescent bulbs with energy-saving LEDs or compact fluorescent bulbs.
  • Consider making the switch to a geothermal heating and cooling system.
  • Schedule regular maintenance for your HVAC system to ensure optimal performance and efficiency year-round.

What is AFUE?

AFUE is an acronym for Annual Fuel Utilization Efficiency ratio and is used to identify the efficiency rating of your furnace or water heater. AFUE is represented as a percentage, and the higher the AFUE, the more efficient the appliance. For example, with an AFUE of 80%, 80% of the fuel consumed is used to heat your home, while 20% is lost at some point during the combustion process.

Why do I need preventive maintenance?

The best way to ensure the reliable, efficient performance of your HVAC system is with regular maintenance, including the inspection, cleaning, and tuning of your equipment. We recommend preventive maintenance each spring and fall to prepare for the seasons ahead, and we encourage our customers to join our Signature Comfort Club to enjoy benefits such as:

  • Lower energy bills
  • Fewer repairs
  • Improved air quality
  • Prolonged lifespan of HVAC equipment
  • And more!

How do I know if it’s time to replace my HVAC system?

Towards the end of its usable lifespan, your HVAC system starts to lose efficiency and parts will begin to breakdown more frequently. If your HVAC system is 12 years or older, is unable to maintain your desired level of comfort, or it is costing you a fortune in repairs, we recommend HVAC replacement.

What is a ductless mini-split?

A ductless heating and cooling system allows you to control the temperature in your home without the need for ductwork. A ductless system consists of an outdoor condenser and one or more wall-mounted, indoor units. These two components are connected to each other via a conduit that runs through a small hole in the exterior wall of your home, which contains a condensate drain, refrigerant line, and power cable.

Should I zone my home?

A zoned HVAC system allows you to heat or cool each room or zone in your home individually, rather than controlling the temperature of the whole house at once. A zoned system can help you save money on the cost of energy, enhance air quality by preventing the circulation of contaminants, and increase your comfort, one room at a time.

The process was very customer focused starting from Scott McHale's engagement to organize the project to replace our old A/C, to an professional job John & Matt had done in installation, and Bob Seeger'r post installation service to troubleshoot the air flow damper, great job."

-Hosum Li

"Very confidant! Our technician Bob Seegar was great."

-Debbie Kaba

"I would highly recommend Signature for all HVAC needs."

"Bob Seeger was our technician this time around. His level of professionalism was exceptional - it really stood out! Overall we are very happy that we switched to Signature several years ago!"

-Mark Kenney

"The Signature techs who come out to our house are always top-notch professionals. Very courteous, careful, and thorough. They always provide great explanations of the work that they are doing. I never feel like I am being pressured into unnecessary work or equipment replacement (like I used to feel with Service Experts). Today, Wade was the tech who came out. He was here exactly on time at 8am, and was done within an hour. Great work and another great service experience from Signature! Update 9/27/2016 - Today Bob Seeger came out to service our system in preparation for the winter. I was extremely impressed by his professionalism and courtesy. Before he started, we sat down and he clearly explained what he would be doing as part of the maintenance, and we agreed upon the need to replace the filter on the main unit, and also to perform humidifier maintenance as part of the work. After the work was complete he made recommendations for overall system enhancements that we should consider. Signature really has top-notch people working for them, and I continue to be extremely happy that we switched over to them several years ago."

-Mark Kenney

"Bob Seeger was our person to service our furnace and water heater. He showed me a problem with our water heater that could have been a major problem. He was very honest, great and so efficient! He fixed the problem. I am kind of hoping he will be the one to work with in the spring."

-Debbie Kaba

"Always feel confident with the work performed by Danny from Signature."

-William Stolting

"Bob was quite knowledgeable of the type of geothermal system that I have in my house. Before completing the annual maintenance/tune-up that I had requested, he asked relevant questions about my geothermal system (e.g., date of installation, last service, temperature preference, electric usage, etc.). After inspecting and servicing my system, Bob explain service that my system needed now and recommendations that would benefit my system. He explained the options in a non-pressured approach, as well as, the benefit in joining Signature HVAC's service plan which was helpful. Throughout the service visit, Bob was courteous, friendly and respectful. My wife and I were very satisfied and we plan to continue to use Signature HVAC in the future."

-John Schmitt

"Bob did an excellent job. He showed up on time, was courteous, and respectful. I recommend using Bob S from Signature Heating and Air-conditioning."

-Dennis Carlson

"Great service as always. Always prompt and knowledgeable."

-Adam Lusk

"Bob was very professional and informative on the heating & air condition job at my house. He is a very nice and caring person! Thank you!"

-Colleen Esgro

"Your whole team is outstanding."

-John price

"Daniel Cross (Signature) completed a thorough and quick fall service on my heating systems. What I liked best about Danny is that he spoke to me as a knowledgeable customer rather than treating me like a clueless homeowner. So refreshing to be treated with respect by an HVAC provider! He had an opportunity to "upsell" me on a service, but was honest and told me that it wasn't valuable in my situation. I would certainly trust him to service my equipment again, and would definitely recommend him to a friend."

-Susan Wentz

"Thanks again for walking me through the process and pointing out what was going on in my system. Mold be gone! Professional and friendly service. Thanks for your help."

-Mia Bosna

"Travis is another courteous, fine professional working for you!"

-John price

-Ric DeAngelis

"We are very pleased with Signature and their very knowledgeable Technicians. We will be continuing our By-Annual service/tune-up with them...."

-Ric DeAngelis

"I have used Signature for about 10 years now. They provide excellent service. Bob Seeger was my most recent technician and he was on time, polite, informative, and technically proficient. I highly recommend signature for your HVAC needs. I have geothermal, and they are excellent at this technology."

-Charlie Phillips

"Mike B came out for the biannual check of the upstairs system--we had replaced the downstairs system in June---we are very satisfied. Mike was thorough, very professional, answered all my (sometimes inane) questions and kept the house clean. Good job Mike and thanks."
