How can we help?

1. Tune and Clean your Furnace

Would you drive your car 50,000 miles without an oil change? Of course not! The same logic holds true with your HVAC heating & cooling system. Yearly tune-ups will keep your equipment running more efficient just like a car tune up helps with better gas mileage. Tune-ups can also help with the “Wear & Tear”. Routine service checkups can catch potential issues before they become real problems. It also important to protect your warrantee. If equipment shows signs of neglect, Manufactures could void your warrantee. Seasonal maintenance will help ensure that your heating & cooling system operates dependably and within the manufacture specifications. We send NATE-Certified technicians equipped with advanced diagnostic tools to test ,inspect, clean and calibrate your HVAC heating & cooling system.

2. Use a Programmable Thermostat.

To regulate your home’s temperature. Programmable thermostats save energy by offering four convenient, pre-programmed temperature settings that scale temperatures back when you are away and scale up when you return. Set your thermostat no higher than 68 degrees when you are home and lower the temperature when you go to bed or when you are not at home.  For every degree you lower your thermostat you save about 2 percent off your heating bill.

3. Make sure your furniture isn’t blocking your home’s heating vents.

Make sure furniture, carpeting or drapes aren’t blocking vents and all vents are open. In cold weather, keep draperies and shades on south facing windows open during the day to allow sunlight in. Close them at night to retain heat. Also remember to use kitchen and bath ventilation fans wisely. In just one hour, these fans can pull out a house full of warm/cool air. Turn fans off as soon as they've done their job.

4. Insulate

Up to 45% of your home’s energy is lost through the attic. Check your attic insulation to see if it meets the recommended value (R-44) for our area and add insulation as required.

5.Check heating/air conditioning ducts for leaks.

Examine your house’s heating ducts for leaks. Think of your ductwork as huge hoses, bringing hot air instead of water into your house. Mostly out of sight, ducts can leak for years without you knowing it. The U.S. Department of Energy and the Electric Power Research Institute determined … 25% to 40% of the heating and cooling energy put out by heating, ventilating and air conditioning systems … is lost through the ductwork system.

6. Change the filters in your furnace

Basic furnace filters are designed to trap dust, dirt, and airborne particulates before they can get into the system and potentially damage the fan or the AC coil. Since most of the air in your house circulates through your HVAC system, furnace filters are your first line of defense against dust and airborne allergens.If you’re not sure where filters are or how to replace them, ask Us. Dirty filters force the system to chug, wasting energy and costing you anywhere from 10 to 30 percent more energy. Typically you should change a basic, fiberglass or paper furnace filter every one to two months. And you should change or clean an electrostatic or HEPA filter every two to five months.

7. Hot Water Temperature

Reset your hot water temperature from 125 to 120 degrees and you can save $22 a year and it’ll also help lengthen the unit’s lifespan by slowing sediment build-up. Install an insulated blanket on your older water heater to cut standby heat loss. You can judge whether it’s necessary by touching the tank. If it feels warm, you can benefit from adding this extra layer of insulation.

8. Ceiling fans

If you have ceiling fans in your home, look to see if you have a reverse switch near the electrical pulley. The correct direction of the fan during the wintertime should be clock-wise and set the fan on low. Since warm air rises, the winter setting allows the warm air to be circulated back downwards. Using ceiling fans to re-circulate warm air can save as much as 10% on your energy bills.

WOW, what a great job Gustafson Heating and Air Conditioning did for my wife and I. They were professional, fast, and way less expensive than the others we looked into. We really appreciate what they did. It was in the winter when our furnace broke down and they replaced it immediately. They left our home clean and warm and we will appreciate the cool air this coming summer. THANK YOU Mike and your team!

I received a number of quotes to install a whole home humidifier. Gustafson was amazing from start to finish. I was able to handle everything over the phone without needing an additional in-person quote with a number of upcharges. I spoke to a gentleman who walked me through options by seeing pictures of my setup and was extremely knowledgable on what was necessary to ensure I was getting the correct humidifier for my home. The pricing was extremely competitive compared to the others and was not full of hidden charges. When I called, they were able to get an appointment set up within a week. The service tech was on time, courteous, cleaned up after himself, and walked me through the whole setup.

I got three quotes for a heat pump and gas furnace back-up. Gustafson’s was the most competitive. In addition, Mike McCarthy was, and is, a gem; very knowledgeable and responsive. The other Gustafson employees on the job were courteous and professional. I am very pleased with the equipment and the installation, which was a difficult one. I highly recommend Gustafson!

Meagan P.

Gustafson installed our HVAC system in 2019 and have been so great with service! They’re honest and back up their work. Recently our A/C wasn’t cooling to the set temp. Todd was so kind & diligent in teaching us what to do as homeowners, but also servicing/cleaning the mechanics and we’re back to a nice, cool home just in time for higher temperatures!

Scott H.

Purchased a mini-split (AC / Heat Pump) unsure if I’d be able to install it or not. I installed most of it myself but there were a few technical procedures I didn’t have the expertise or tools to undertake. Dillon came out and finished the job, doing top-notch work and taking in account the aesthetics of the unit inside and out. Very reasonable price as far as I’m concerned. My new go to neighborhood HVAC company.

David R.

Basement flooded. This is where my WFH office is, so it was a big deal. Gustafson sent out Todd to fix it. He got it fixed quickly, and charged me a very reasonable fee. Basement is warm and dry now. I can’t say enough good things about Gustafson.

Steven B.

The technician “Luis” was fantastic as usual. All the services and technicians we have used with Gustafson over 12 years have been prompt, professional, timely and reasonable over the years. I definitely approve of this vendor!!!

William R.

Our furnace went out and our regular company gave us a 2 week window for coming out. We have a RHEEM furnace and needed an authorized RHEEM dealer. I called Gustafson and they came out in 48 hrs. They were so nice and the technician –Dylan–was so helpful that I am switching companies. Really a great experience.

Sonja L.

Absolutely the best!!!! This is an honest company with very professional people working for them. The price for all work is always very fair and very reasonable!!!

Krista B.

I had the whole HVAC system installed by Gustafson about three years ago and recently requested maintenance on the system. Technician Robert Gomez was the tech that responded and he was very personable, easy to talk to, and explained what he was doing to me to service my furnace. I felt like I received thorough service and he provided advice for the future as well. Thank you, Robert!! I hope to be able to request you again in the future to do maintenance on my AC next spring.
