Cooling Your Home When You Have Pets: What Vets & HVAC Pros Recommend

Published June 22, 2025

Keeping Pets Comfortable and Safe During Hot Weather

As temperatures climb each summer in Lake, Napa, and Mendocino counties, pet owners face a unique challenge: how to keep indoor temperatures safe and comfortable for pets. Unlike humans, cats, dogs, and other household animals can’t tell us when they’re overheating—and some are much more vulnerable to rising temps than others.

At Jonas Energy Solutions, we understand that for many of our customers, pets are family. We also know that wildfire smoke, rolling blackouts, and sudden heat waves can quickly turn an average home into an unsafe environment for pets. With input from veterinarians and our own HVAC pros, here are the top recommendations for keeping your home cool and your pets protected during California’s hottest months.

Why Pets Are More Heat-Sensitive Than People

According to the USDA’s technical guidelines for pet temperatures, most dogs are at risk of heat-related stress when indoor temperatures exceed 80°F, especially larger breeds or those with thick coats. Cats, rabbits, birds, and small mammals also have less capacity to cool themselves than we do. Factors that can increase risk include:

  • Breed type (flat-faced breeds like pugs or Persian cats are most vulnerable)

  • Age (senior pets and very young animals overheat more easily)

  • Health conditions (respiratory, heart, or weight-related issues)

  • Indoor humidity, which affects cooling effectiveness

  • Heavy coat types or long-haired breeds

1. Set the Right Indoor Temperature

What Temperature Is Best for Pets?

Most vets recommend keeping your indoor temperature between 72°F and 78°F during warm weather, and below 80°F at all times when pets are indoors.

  • Program your thermostat to prevent large temperature swings throughout the day

  • Use “away” settings carefully; don’t raise the thermostat more than 2-4 degrees when out

  • Avoid setting your system too low, which can tax the equipment

  • Ensure that filters and coils are clean for maximum efficiency

Why System Maintenance Matters

If you have an older AC unit or haven’t had maintenance in the last year, your system may not cool as evenly as it used to. For homes with pets, Jonas Energy recommends seasonal AC maintenance to prevent breakdowns.

2. Improve Airflow and Circulation

Why Airflow Is Key for Pet Comfort

Even when the air is cool, poor circulation can trap heat in certain rooms or floors. Pets that sleep in these areas may be at greater risk of overheating.

Steps to improve airflow include:

  • Keeping interior doors open to promote circulation

  • Using ceiling fans (counterclockwise) to distribute cool air

  • Having ductwork inspected to eliminate leaks or blockages

  • Installing return vents in closed-off rooms if needed

Checking Hot Spots in Your Home

If your pets tend to nap near certain vents or in specific rooms, it’s a good idea to verify whether those areas are staying cool and ventilated. Our team can test airflow and recommend improvements.

3. Monitor Humidity Levels

Why Humidity Affects Pet Cooling

According to the U.S. Department of Energy, indoor humidity should stay between 30% and 50%. Higher humidity makes it harder for animals to shed heat.

Signs of high humidity:

  • Damp smells in certain rooms

  • Condensation on windows

  • Sticky floors or furniture

  • Pets panting excessively despite AC running

How to Manage Humidity

  • Use a dehumidifier if needed

  • Check for drainage problems in your HVAC system

  • Ensure your HVAC system is properly sized to manage moisture

4. Filter Out Smoke and Pollutants

Why Wildfire Smoke Is Dangerous for Pets

Pets’ lungs are more sensitive to airborne particles. During wildfire season, smoke and poor filtration can cause:

  • Coughing or sneezing

  • Wheezing or labored breathing

  • Increased risk of respiratory infections

What Filtration You Need

  • High-efficiency air filters (MERV 11-13)

  • More frequent filter changes in smoky months

  • Full system cleaning after wildfire events

Our AC maintenance includes filtration checks to ensure your pets are breathing clean, safe air.

5. Prepare for Power Outages

Creating a Cooling Backup Plan

  • Install a whole-house generator

  • Use battery backup fans if needed

  • Provide cool mats or frozen water bottles for pets

  • Never leave pets unattended for long periods in summer

Be Prepared for Fire Season

If you’re leaving town during peak wildfire season, make arrangements for a pet sitter or trusted friend to check on your HVAC system and indoor air quality regularly.

6. Keep Your HVAC System Pet-Friendly

Unique HVAC Needs in Pet Households

  • Pet hair and dander clog filters faster

  • Fur can coat coils and affect drainage

  • Curious or scratch-prone pets can damage low vents

Maintenance Frequency for Homes With Pets

For homes with multiple pets or heavy shedders, we often recommend quarterly maintenance instead of annual. Pet hair buildup reduces energy efficiency long before filters appear visibly dirty. Let our pros create a service plan that fits your needs.

7. When to Call the Pros

Signs It’s Time to Schedule HVAC Service

  • Uneven cooling or warm spots where pets rest

  • Frequent HVAC cycling or longer run times

  • Unexplained humidity or damp smells

  • Visible pet hair in return vents

  • Poor air quality after smoke events
