Frequently Asked Questions

Is 24 hour service available?
Absolutely, we offer 24 hour emergency service for all customers. Rates outside of our standard business hours are slightly higher than work completed during business hours.
Can you just send me a proposal without sending someone to my home?
Sure we can, but we do not recommend this. The reason we ask for a home or site visit is to help determine what are we pricing, single stage, 2 stage? What is the load calculation? What are you wanting the system to do? What is the seer rating/efficiency rating you want? Where is the equipment going to be placed, attic, crawl space, basement? What is the existing duct sizing, can it handle the air volume? If a furnace, are we upgrading to a 90% efficiency rating? Is the flue piping correct? Keep in mind that whatever we touch relating to an install must be brought up to standards of existing building codes. As you can see, there are many factors that go into a proposal and we want to make certain we covered them all. We know your time is valuable. We respect this and will keep the meeting as brief as possible while ensuring thoroughness.
What is the most efficient system for a home like mine?
When a load calculation is done we will know the correct sizing for your home. From there we can discuss the available options to meet the sizing requirements. Systems are not “cookie-cutter” anymore! There are many considerations. The only way you can make the best decision is to have a knowledgeable, licensed HVAC dealer meet with you to go over the options and features that are available and fit into your budget.
Are programmable thermostats really worth installing?
In a nutshell, yes. Daily and weekly schedules may be programmed adjusting the temperature of a home for maximum energy savings. Every family uses their home differently. With today’s wi-fi capabilities, broad range of programming features, and high efficiency equipment, homeowners are capable of maximizing comfort and energy efficiencies!
Why do I have to have a load calculation?
A load calculation takes into consideration the square footage of your home along with insulation values, windows, doors, and orientation (north, south, east, west) to determine the proper BTU size that will best cool/heat your home to a specific design temperature. The days of “guessing” based on square footage can lead to serious sizing issues with today's construction and equipment design/engineering.
What is an energy audit?
A Home Energy Rating is a measurement of a home’s energy efficiency. In the United States, the Residential Energy Services Network (RESNET) is responsible for creation and maintenance of the RESNET Mortgage Industry National Home Energy Rating Standards, as well as certification and quality assurance on RESNET Provider organizations. Home energy ratings can be used for either existing homes or new homes. A home energy rating of an existing home allows a homeowner to receive a report listing options for upgrading a home’s energy efficiency. The homeowners may then use the report to determine the most effective ways in which to upgrade the home’s energy efficiency. A home energy rating of a new home allows buyers to compare the energy efficiency of homes they are considering buying.
Can I install a larger system, wouldn't that be better?
NO – NO – NO!!! Installing an oversized system will lead to major problems. Part of the job of an air conditioner is to dehumidify your home. By oversizing the a/c system you will get very little dehumidification but lots of cold moist air. When this happens, mold becomes an issue. In the heat mode an oversized furnace leads to premature failure of the heat exchange, short-cycling of the system and wasted energy, all of which translates to higher utility bills. In addition, you won’t be able to keep the home comfortable with the furnace starting and stopping all the time.

Spring Cleaning For Your HVAC System
When we think of spring cleaning, it usually entails images of “out with the old and in with the new”. Glistening windows, winter clothes and boots packed away and maybe even flowering blooms in our garden are some of the first images that come to mind. A home owner’s spring cleaning should also include the HVAC System. Here are some tips to help you with.
1. Schedule your HVAC Preventive Maintenance with Evans Air Services. Our professionally trained staff will perform rigorous testing and basic maintenance of your unit to ensure you stay cool this summer. Review this list of steps we take to provide you with HVAC maintenance. (Link to checklist)
2. Consider Programmable Thermostats. Programmable Thermostats allow you to customize your home’s temperature and can help save you money. Wifi enabled allows more control to customize your home environment.
3. Go Green (or greener). Use ceiling fans to help cool your home. You can reduce the temperature of your home by 5 degrees when you use ceiling fans effectively. Also close any blinds that allow direct sunlight into your home during the day.
4. Check your doors and windows for leaks. Caulk and/or replace seals where you find cracks and gaps.
5. Have your ducts tested for leaks and air flow pressure.
6. Consider upgrading your existing unit to a more energy efficient system. Just as our vehicles and appliances need to be replaced after years of wear and tear, the same is true with our heating and air systems.

Winter Heating Tips
Winter can be a beautiful time of year. It can be a very expensive time too. Between holiday expenses and heating bills, a budget can get thrown out of whack quickly. Post-holiday credit card bills and cold weather usually arrive about the same time. Here are some home heating tips that will save you money and help with energy efficiency.
Schedule maintenance for your equipment. This is probably the most important thing you can do to ensure your home stays warm for your family.
Use programmable thermostats. If you do not have programmable thermostats consider investing in them. When used correctly, they pay for themselves in a very short period of time.
Change your filters. Clean filters help the air flow freely and allow your heating unit to operate more efficiently.
If your home has a fireplace, close the damper when you are not using the fireplace.
Keep your garage door closed.
Caulk and weather strip doors and windows.
Keep blinds and drapes open during the day and closed after sundown.
Rearrange furniture so it is not against an outside wall.
Don’t block vents. Air needs to move freely.
Lower your thermostat at bedtime. It’s a proven fact, we sleep better when we decrease the temperature.
If you will be gone for 8 -12 hours lower your thermostat 10 – 15 degrees.
When traveling overnight or longer, lower your thermostat to 55 degrees.
Heat pumps work efficiently at 68 degrees and lower.
As you can see, by taking a few simple steps, you can reduce your heating expense while also be an efficient energy consumer.
