Quality work




Review of Interstate Heating & Air Conditioning

During the last icy blast, my heater went out. Isaac work in subzero temps to get my heater going, and Brandon followed up with a permanent fix the next week. Polite, caring, considerate. My comfort was their concern.


Amazing service and technician.

Our technician Brandon Nelson was awesome. Got our system back up and running on a day he didn’t even have to be working.

Review of Interstate Heating & Air Conditioning

Lost my heat last night. It's a 90% unit so drain line froze. Isaac made it out around noon and fixed everything over a 2 hour period including having to go get some new pipe in the snow. Did a great job, professional and neat. You need more techs like him.


Isaac was great!

The Tech arrived and went to work checking my heating system and the thermostat and solved the problem I had with getting heat on a very cold Tuesday. Both my two dogs and I were able to have a great nights sleep.


Great, prompt service.

Courteous and Professional Service




Review of Interstate Heating & Air Conditioning

Gordon was thoroughly informative, pulling no punches in explaining to a lay person the dilemma my tired, old furnace is putting me through. He performed the postmortem and presented the results. The cost to resurrect from the dead? A shock. Sadly, a 'no-can-do' situation ... during a prolonged arctic blast of winter weather, no less. In spite of the cost of repair I won't hesitate to recommend Interstate ... professional, expedient, approachable from Meghan (in the office) to Gordon, the technician.


Great and friendly service!

I was extremely happy with the service. Brandon remembered me from the year earlier. He was very pleasant and professional. Thank you so much.


Professional and Respectful Technician.




Review of Interstate Heating & Air Conditioning

Brandon arrived earlier than the appointment time. I very much appreciated that. He was very courteous and knowledgeable. I had questions - as with many services I had used - Brandon answered my questions patiently and courteously. He treated my questions with dignity and respect. Although, I am a woman; Brandon did not belittled nor demeaned my questions and inquiry in any way. He had the problem with my Mom’s heater fixed within an hour. The price charged for the service was quite reasonable. Thank you for your prompt and timely service. And thank you for helping to solve our problem. I definitely would recommend this company and the technician Brandon Nelson. I will definitely use the company again in the future with these service needs. Thank you!!!

Great Service




Review of Interstate Heating & Air Conditioning

My appointment was scheduled for 3-5 pm. The tech assigned for my job happened to finish the job before mine early, so the office text me to ask if I would mind if the tech could come early. The tech, Isaac, was very friendly and knowledgeable. He found that my furnace igniter had failed and needed to be replaced. He had it back up and running again in a snap! Needless to say, I am very pleased and will be using Interstate for all of my future heat and air conditioning needs.

I arrived to bid a heat pump replacement. I found the system to be a r22 system and we will need to replace the evaporator coil with the outdoor system at a minimum. I recommended to repair the compleat system and have a matching systems that will last another life time like this existing system has. I gave multiple options to replace the system in different set ups to fit the homeowners needs. If you have any questions on the set up on the bids please contact me and I will do any I can to help you anyway I can. Jake Kring.

I arrived for. Blue member no heat call. I first inspect the system and found that the down button on the thermostat was shorted to lower the temp at all times. I recommended to repair the thermostat. The homeowners decided to replace the thermostat. I installed the thermostat and we couldn’t not get the thermostat to program to the homeowners phone. We decide to set it up as a normal operation thermostat. I cycle the system on and walked the homeowner through the new thermostat.

Blue shield plan fall tune up in 2007 Lennox Air handler. Customer had an issue with recent snow storm of home struggling to warm up. Thermostat was set to 68 and home was 62. After opening vents and doors the home did catch up, though. Checked filter, ductwork, plenums, evaporator coil, blower and blower capacitor. Checked sequencers, heat strips and electrical draws. System is operating within manufacturer specifications, but the ductwork does have issues as outlined from previous summer tune up. The returns are undersized and the supply ductwork has been run poorly, especially to the further reaches of home, causing air balance issues. After going over previous tune up recommendations, including heat load in attic due to poor ventilation and insulation, and ductwork design, customer is interested in having a return duct cut in in dining room area. Would like to run 1 16” duct from a 14x30 angle box to increase return air and help far reaching supplies get more velocity. Customer w

I arrived for a recall on a new system we installed. I spoke with the homeowner and found that the system will run a lot and not heat the home. I inspect the thermostats and found it to be running heat and emergency heat with the demands I gave it. But I could not make it do it on ones own. I explained that the thermostat normally brings on the email heat 2 deg lower that the recommended settings. It was 63 deg in the home and the thermostat was set to 68 deg and the system was only running heat pump mode. Agin the system ran in emergency heat and heat pump mode when I gave the demand but I couldn’t make it run in emergency heat on its own with a temp deference farther that 2 deg. I also found a duct to be completely disconnected on the plenum. This was dumping the conditioned air into the attic and it would not satisfy the thermostats anyway. I reconnected the duct and check the systems operations. I found no others issues with this system at this time.

Checked burners, flue, inducer and cleaned flame sensor. Checked blower, blower capacitor and heat exchanger from below. Checked drain and evap coil. Cycled system on and checked gas pressure and replaced gas caps. Checked electrical system, heat rise and delta t. Heating components are all working within manufacturer range. Dust is building up on ceilings from supply vents and hanging on return grill, also recommend having air ducts cleaned.

I detached the drain and thawed out the collector box. I was able get the collector box to drain, and put a bucket underneath drain.

Came out to call. System wasn’t heating properly. Customer stated that the furnace wasn’t blowing warm air, and is not on at this moment. I checked system over and found the 90% condensation drain frozen that goes underneath the house. Due to the weather conditions and how frozen the pipe was, I was not able to thaw it out. I reran heat drain temporarily to get customer heat, until we can come back and install a condensation pump for the heat drain. I will leave ticket open until then. Came back out to call and discussed with customer about just using original drain or running the condensation pump. I checked the primary line and it was still blocked due to it being frozen. Told customer we could run a condensation pump line to the washer drain and discussed pricing on that. After going over options, customer wanted to see if line would thaw out by next week, and if not, have us run the pump then. I will leave ticket open and have optional estimate available.

Came out to call. Customer stated that the system wasn’t heating the home. When I arrived the system was set at 88 and the temperature on the stat was 70. Customer stated that it seemed cold in the home and the system wasn’t keeping up. Customer has an add on to the house that has its own separate heater and hasn’t turned it on until today. I checked furnace over and found nothing wrong with the furnace and how it’s operating. EZ flex was changed last service and wasn’t that dirty. There isn’t a lot of insulation in the attic and customer could be having heat loss due to the extremely cold temperatures outside. Recommended insulation be added in attic. Customer also had doors closed on the side of the home where the thermostat is. I recommended having the doors open to allow the air to cycle properly. Told her I’d leave the ticket open, and if we need to come back we will.

Came out to call for a system not heating properly. Customer stated that the system would shut off intermittently, and the thermostat would still be calling for heat. I checked furnace over and found the system to be a 90% furnace. Sounded like the inducer motor was swishing around some ice particles and water. I cycled system on and found that the system is actually short cycling due to pressure switch. I checked and cleaned the hoses and inducer chamber out. I also cleaned the flame sensor due to some build up being on it. These are likely causing the system to have intermittent faults that don’t always happen consistently. I tested and verified that the system is cycling on without fault, that all condensation drains are clear, motors are operating within range and gas pressure is correct. Had customer cycle on furnace from thermostat to ensure thermostat is communicating correctly. System is now heating properly within manufactured specifications.

Came out to call for a system not heating properly. Customer stated that after the rolling blackout the system hasn’t been working quite the same. I checked system and found it reading a code for a lockout due to ignition proving failure. I reset system and cycled it on to check operation. System fired up fine, with no problems. System did cut off one time and then worked since then. I inspected the flame sensor and found it to be dirty. Recommended that customer have me clean it, but also have us come out to do the maintenance on the system twice a year to take care of it, and have issues like this happen less or not at all. Customer signed up for blue shield membership. I cleaned flame sensor and cycled furnace on. Checked all electrical components and amps. System is now heating properly.

Came out to call for a not heating well. Customer stated that the furnace was making a strange noise and that the heat wasn’t working. I checked the furnace over and found the noise coming from the inducer motor of the system. I took inducer motor out and found the plastic wheel inside the inducer motor assembly had broken into pieces and was not allowing the system to heat. I went over what I found with the customer and discussed pricing on repair vs replacement of furnace. Customer wanted to do repair at this time. I picked up new inducer motor assembly and came back to install it. Once installed I went through the systems operation sequence to ensure system was heating properly. Cleared tubing of debris and made sure it was draining properly. System is heating properly at this time.

I arrived for a non member no heat call. I first spoke with the homeowner and found that we already have replaced the gas valve and the induced draft motor. I inspected the system and found that the induced draft motor has failed. I called the manufacture for part replacement but manufacture dose not have the part in stock. To order a motor it will be about 3 days depending on weather. Another technician has a motor on his truck. I contacted the technician and dispatch to get the other technician out to see if the motor he has will work on this system. I recommend to have the furnace replaced vs to keep making big big repairs to this system. I gave the homeowner a option on a one time offer to replace the furnace and give the cost of the parts back towards the furnace replacement. This is good for today only. This is us trying to keep you from making big repairs on this system and to get you a new furnace with a 10 year parts warranty. This is also keeping you running and comfortable u
