Before You Seal the Deal 

Check the HVAC System

If you are unfamiliar with these systems, hire a technician to check the HVAC systems to make sure the functionality and efficiency of the systems are intact, and determine if they need any tune-ups. It also would be helpful to get an estimate of the age of your furnace and air conditioner to determine if it is near the end of its lifespan and budget for any future breakdowns. 

Additional tips:

  • Check both heat and air conditioning systems to ensure they function properly
  • Understand the type of filter you need to use
  • Learn the shut-off locations for gas and water (in the case of an emergency leak, you should familiarize yourself with the locations of your shut-off valves, so you can quickly respond to an emergency)
  • Learn where your circuit breaker is for maintenance and repairs.

Test Your Thermostat

It is essential that your thermostat is working properly, so you can adjust the temperature of your home and live comfortably.

Request a Thorough Clean if Buying Resale

Make sure your new home is thoroughly cleaned before you move in. It will catch any problems that initially went unnoticed. Make sure the vents in all rooms are clear of dust and move any obstructions.

Inspect and Test for Asbestos

Asbestos testing is critical for your family’s health. Asbestos was used in insulation before the 1970’s (before they knew it was harmful to humans). Asbestos dust can be inhaled and accumulates in the lungs over time, which could cause serious health problems, and possibly cancer. It is better to be safe than sorry and have your new home tested for asbestos.

Check for Mold and Mildew

Inspect your new home for mold and mildew, especially the bathrooms. If the bathroom doesn’t have a window or ventilation fan, that could become a problem in the future.

Inspect Sprinkler System (if appropriate)

Inspect the condition of the sprinkler system to determine if it is working properly. In addition, if you live in colder climates, you need to shut off the sprinkler system to protect it from damage and a hefty repair bill.

Inspect for Bugs and Pests

Check your home for termites, ants, mice, etc. You may be able to use a spray can for smaller bug infestations like ants, but you would want to hire a professional for severe cases like termites. Be sure to seal any holes that mice and other pests could enter through. This is why that thorough clean is so beneficial when you first move in, because you are more likely to notice and fix bug and pest problems early on.

Check the Grading of the Yard

To prevent future water damage, check if the grading slopes away from your home. If it does not, you may have to adjust the grading of the yard or install a drainage system to eliminate water damage. 

Immediately After  

Change Your Locks 

For safety purposes, it wouldn’t hurt to change the locks of your new home because who knows what the previous owners did with their old keys. It is a simple project, whether you install the new locks on your own or you hire a locksmith.

Get an Energy Audit

An energy audit assesses your home’s energy consumption and efficiency. This is an easy way to help you make adjustments or upgrades to minimize your energy bills in the future.  

Test Smoke and Carbon Monoxide Detectors

Make sure your smoke and carbon monoxide detectors are working properly.

According to the National Fire Protection Association, 40% of home fire deaths were in homes with no smoke alarms. It is crucial to have working detectors in your home for your family's safety. You should check your detectors once a month and remember to change the batteries yearly!

Inspect Fire Extinguishers

Locate your fire extinguishers in your home and make sure they are working correctly in case of an emergency.

Check Your Garage for Proper Ventilation 

It is vital to check the framing of your garage to determine if it is adequately ventilated to reduce the chances of carbon monoxide poisoning.

Make a Homeowner’s Binder

This is an easy way to keep track of all your insurance papers, repair receipts, and any other information about your home. It will be beneficial to have all this information in one place, and will help make the process of selling your home later on much easier.


Check or Replace Air Filters 

Replace your air filters and try to change them regularly to create clean, healthy air and to prevent damage to your HVAC system. 

Properly Ventilate the Laundry Room 

If the dryer-exhaust system is poorly maintained, that could become a serious fire hazard. It is crucial that the laundry room is ventilated properly to reduce the risk of a fire. Also, have an HVAC specialist inspect and clean your dryer vent annually as lint is a major cause of dryer fires.

Create a Home Maintenance Checklist by Season

Spring & Summer

Spring cleaning isn't just a saying-- it's a huge time for home maintenance. This is the time to focus on your home's exterior since it just went through winter and will be preparing for summer's imminent heat soon enough. Summer means great weather, so get outside and spend some time on your lawn and garden when you aren't working on the exterior of your home.

  • Clean window air conditioners
  • Power wash and repair deck or patio
  • Get your AC system ready for summer; consider having it serviced
  • Take care of any insect problems you might have
  • Clean/repair your deck or patio as needed

Fall & Winter

Fall is that in-between season where you're either finishing up summer maintenance tasks or readying your home for the winter. Winter throws a lot at your home (think rain, snow, ice, and wind), so be sure your winter preparation isn't something you procrastinate on. 

  • Winterize your sprinkler system
  • Flush your hot water heater & remove sediment
  • Winterize your AC system. If you have central air, be sure to cover the outside unit with either a tarp or sheeting and secure it with some bungee cords.
  • Get your heating system ready for winter. Make sure heating vents are open and not blocked. Get your furnace serviced/ inspected at minimum every other year (annually is preferred though)
  • Routinely check for icicles and ice dams

Both Spring and Fall

  • Clean gutters
  • Check for leaks in windows or doors
  • Check for roof damage (spring and fall)

Gutters: They control the flow of rainwater to protect your roof and siding. Be sure to clean out your gutters twice a year and check for damage to reduce the risk of a roof leak or water damage. You can clean your gutters by using a ladder, just be careful. If you're not comfortable cleaning your own gutters, you can hire a professional.

Leaks in windows or doors: An easy way to inspect your windows and doors for leaks is to stand right next to them and see if you feel a draft. If you do, you may want to replace them or use caulk. If your windows and doors aren’t properly sealed, it's a telltale sign when your energy bill shoots up.

Roof damage: Have an inspector check for loose or damaged shingles that could cause water to enter your home. They will also check the vents for damaged or cracked mastic.


Although this may seem like a lot, it is worth it to get these tasks out of the way early on, and it may even give you the chance to ask the seller to repair it themselves or reduce the purchase price. This will help you reduce the risk in your new home and save money in the long run.

Every home will have its own problems, whether it be a major renovation or a minor tweak. It is beneficial to be self-aware of them, so you can properly budget and be prepared for any future issue that could come up.

We hope this new home checklist is beneficial to you and your family. As a licensed heating and air conditioning company, our commitment is to share ways to help you become an informed homeowner and avoid future mistakes as you begin this new chapter of your life in your new home.
