About Clark Heating And Cooling

“I contacted Keith Comstock with Clark Heating & Cooling on Tuesday, he came out to the house on Wednesday, and my new unit was installed on Thursday. You can beat that for service! Keith was very informative and took the time to explain everything to me. It was obvious he was not there to up-sell me on things I did not need, and carefully assessed what would work best for my house and family.I contacted Keith Comstock with Clark Heating & Cooling on Tuesday, he came out to the house on Wednesday, and my new unit was installed on Thursday. You can beat that for service! Keith was very informative and took the time to explain everything to me. It was obvious he was not there to up-sell me on things I did not need, and carefully assessed what would work best for my house and family. The install crew led by Jason, were very professional and courteous. They arrived Thursday morning on time and had it knocked out by 4 pm. They replaced my furnace and installed a new air conditioning system. The unit looks great and runs great. Our house has never been more comfortable. I strongly recommend Clark Heating & Air Conditioning for any of air comfort needs.”

“Our furnace went out on us and we needed a new unit quickly. Keith came out to our house the day he got back from his vacation. He did a wonderful job giving us our options and had full confidence in him. However once he sent the install team out that is when Clark Heating really shined. The demo crew came out in the evening to start work on removing the old units so they could get us heat as soon as possible. Jake did an amazing job with the demo. There was another guy there too but I did not catch his name. They came the next day and worked hard all day to get the furnace up and running for us. After they were done, Jason stuck around and gave us an in-depth walk through of our new thermostat. Everyone involved did a wonderful job. They were very professional and didn’t mind that I was poking around when they were trying to work. Absolutely I would contact them again in the future.”

“Could not have been a better experience. Installed a replacement air conditioner and furnace on the hottest September day since 1904. Topped out at over 90.Could not have been a better experience. Installed a replacement air conditioner and furnace on the hottest September day since 1904. Topped out at over 90.My hat is off to Jake, Doug and Nathan. Very efficient, helpful and pleasant. Did a couple of things not on the order, just because they needed to be done. Really nice.”

“Clark Heating and Cooling originally installed our Furnace and AC in 2003. They have always provided us with excellent service. I always feel comfortable knowing that they are selling us exactly what we need, and not something that we don't. It is with great confidence that I refer them to all of my customers as well.”
Jay Spiegel

“I highly recommend Clark's Heating and Cooling. My AC went out last Friday. during this first heat wave of the summer, I called Monday morning for service and they sent someone out by 11.30 a.m. My system was shot. By today, Tuesday, they have installed a new one and I have AC. Best customer service I have had in a long time. Awesome from Keith on the first call, to Rich and to Dave and his crew.”
Patte Terry

“I called Clark Heating and Cooling on 11/12/2017 as our furnace was not working. A service guy came out and said we needed a new furnace. My husband talked to the sales person Keith Comstock and the next day Tyler and Doug were at our house to install our new furnace. I highly recommend Clark Heating and Cooling.”

With the warm weather upon us, here are some frequently asked questions:

1. Can I get my A/C serviced in the Spring?

Yes, but we need the outside temp to warm up to 70 degrees.

2. The furnace or A/C is acting up, what can I do?

Always check your filter, especially when the A/C is running. Clogged filters can cause a lot of issues with your equipment. Have a reminder on your calendar to check your filter regularly.

3. What do I do with the Humidifier during the cooling season?

On By-Pass Humidifiers (attached to your comfort system), make sure to close the damper. Because a home that is too humid can not only affect your comfort but it can damage your home.

4. What if I forget to close the damper on the attached humidifier?

If you fail to do this before the summer starts, it can lead to poor air flow in your air conditioner which will draw the cool air back over your cooling coils and cause the system to freeze-up.

5. What returns do I close for the summer time?

During the summer, if you have High & Low returns, close the Low returns. The High returns will help get rid of the hot air, because hot air rises.
