You have to be sold on what you offer to the point where you are convinced that all options are good options. Don’t downplay any of your value, always overdeliver. Don’t say things like “Nobody ever purchases that package.” Or “Nobody bundles all the options.” Nobody to me is one person, every one has different needs and it is up to you, the salesperson and problem solver to determine if the customer is on the correct service. Instead say “This is a commonly bought package.” Or “This is one of the best services we offer.” Or my favorite one when a customer objects as a reactionary defense response “Hey I understand that is might not be for you. All of our best customers once said that.”
Offer options and lots of them. You do exterior window cleaning, exterior and interior window cleaning, maybe a works package with all of the above with tracks, sills and screens. Maybe you offer it with gutter cleaning or power washing or both. Maybe you do just exterior cleaning with power washing and gutter cleaning. Also is it a yearly package you are offering? Bi yearly? Quarterly? Monthly? Hey, someone on this forum made weekly cleaning work, that’s like finding a unicorn right there but he made it work.
Point is, you can offer anything. But don’t make choices limited, imagine if you only had two choices and they said no to both of them. Now what? You lose the sale. Offer many services and many different schedules for them to go on. Instead of them saying no, they will start saying “Hey honey, which one do you think we should go for?” BAM! Sale! Income! Fireworks and celebrations! 
Also if they commit to 2 or more cleanings a year, I offer a discount on service. Sometimes people do want a deal which in this case wouldn’t lower value since you are likely just trying to get them to sign up. Lower value in this case means no sale. So any value is better than what they had before. However, don’t discount just having them get one service. Instead upsell the other services. I promise you will have an interaction like this:
" 399 dollars? That’s way too much!"
If you only had a few options you would be toast. Instead first find their dominant buying motive or what caused them to act in the first place. You can ask this at any time if it’s not immediately known, ask. “What made you agree to meet with me today? Why did you decide to look for a window cleaner in the first place? Why me? Why now? Why not a year ago? 5 years ago?” Usually they will have a motive revealed to you like “Oh we have guests coming over in a few weeks.” Or “We are trying to sell the house.” Or “We are sick of seeing dirt and are willing to do what it takes to get rid of it.”
If you feel they do not need much value state “Let me ask you something. Would you consider moving down a package if it meant you saved 200 dollars?” They will ask what it is and say you offered a mid tier package, you would offer a lower package at that point.
If they are concerned with value, repeat this to them “Would you consider moving up a package if it meant you got everything you absolutely wanted.” Then offer an upper level package for more.
Now you are asking what I just did here. Let me explain. You are seeing if the customer is on the correct service. You will know they are if they say “No! This is what we want.” They aren’t getting angry, they are just really sure. If you think they are angry, send them my way and I will sell them something. Just kidding. 
But also the next offer will now make them decide what product to choose rather than if they even wanted to buy from you in the first place and then you might hear the couple go back and forth about the product rather than saying should we get anything at all. Your next offer will also make our previous offer look reasonable whether or not you moved up or down a package.
Options help, you become a person of service to the customer, not just a regular salesperson pawning off service. You are there to help them with their problem, and you have MANY solutions. Hope this makes sense.
