Reliable and efficient alarm security systems in Melissa, no contract required! No need to stick with us if you want to try another company!

Whether you don’t want to commit to a company without knowing if you’ll like their service or you live paycheck to paycheck and don’t want to be stuck in a contract you’re unsure you’ll be able to afford every month, there are many reasons customers wouldn’t want to get roped into signing up for a 2-5 year contract. With other companies that require contracts, they often require a cancelation fee if you’re unhappy with your service. When you sign up for service with Smith Thompson Home Security, you don’t have a minimum service length, so you’re free to cancel your service at any time.

Don’t get caught in a “free” alarm system scam in Melissa

If something sounds too good to be true, it often is. This is absolutely true with “free” alarm system scams. Most things in life are not free, even if they’re advertised that way. You may not be paying for the security system all at once upfront, but with a higher monthly service charge than other companies, you’re really not saving anything in the long run. Even though they call the system free, with the extra monthly fees those companies charge, you’re paying for the alarm system over the length of your contract.
