I have always had a good experience with CH&C from the initial installation of my new Carrier unit and throughout the annual preventive maintenance and checks. My recent inspection performed by Darren H. was very thorough, professional, and personable. Thanks Darren for explaining each step of your process and recommendations for improved performance of our heating/cooling unit. I have committed to use CH&C for future maintenance and welcome Darren to provide our service.

Cary J. was on time. He was thorough, friendly, and explained many functions to me. He cleaned the system and assured all was running well. I would welcome him back anytime. Heather set up my appointment easily. I'm glad this team is working for me!

I had a great experience with air duct cleaning services from Crystal Heating & Cooling. The front office staff were very accommodating and answered all of my questions. They also were very upfront about the entire process and everything that was included, unlike other companies I spoke to where everything was an add-on. On the day of the service Joe arrived on time and explained the process to me again, and checked in throughout the day to update me on his progress and share photos of how things were going so far. I would definitely recommend this service to anyone considering getting their air ducts cleaned!

I have had them service my equipment for over thirty years. I had always been pleased with the work they do. Today's technicians were courteous, prompt, and did the work without wasting any time. I would be happy to have them back next time.

The staff were wonderful. They worked quickly and were in and out of here in no time. The young man that worked inside the house was very friendly. All in all, this was a great experience and I would highly recommend this company.

I have been a customer of this company since 1999 when they installed my furnace and air conditioning in my new home. Since that time I have had Furnaces and air conditioners replaced in two houses.This past weekone of my renters notified me that the air conditioner was not working properly so naturally I called Crystal to make the repairs. I was told that the unit needed 2 pounds of refrigerant and I authorized the repairs. $375.00 I was assured that everything was fine. On Saturday my renters called to inform me that the a/c was not working. I called the emergency number for Crystal and informed them of the problem mentioning that the renters were in their 80s and i was concerned for their well being, by Monday i still had hear nothing from Crystal Heating so I called again on Monday morning and was told that they would try to get someone out that day or the next. My next contact from Crystal w as that the unit had a leak and when asked why that was not noted on the first visit the only answer I got was that a new unit was needed. I am extremely unhappy with that service after having been a long time customer. NEVER AGAIN will Crystal get any business or referrals from me.Mike Bowzer

Cary was fantastic! He took time to show me what was wrong and was quick to replace the part which he had with him. He even took the time to show me things on my Carrier Infinity thermostat that I didn't even know about like the savings of my heat pump! I highly recommend Crystal Heating and Cooling for their promo, courteous service, and especially Cary J!

I called and they came out within an hour amazing!!! Had the problem fixed and I was back to sleep to make my shift. Thank you guys so much for taking care of us in our time of need..Simply wonderful customer service. A+ 5 Stars 2 Thumbs 🙂 I am so happy I am doing a routine service contract. Again thank you! Greg.

Had a Carrier Furnace and Air installed by Chris S. who did an outstanding job at my rental property on 10-July-2018... this is the second time I've used Crystal Heating & Air and highly (I mean STRONGLY) recommend them to perform any and all type of heating and air conditioning work you may need done... They are courteous and have VERY competitive prices around the area... My rental is in North County, and they have no problems traveling north of Crystal City to assist your needs... Thanks CHRIS for your HARD Work today!!...Had (2) NEW Carrier units installed on my house today (8/11/16) and had both Jason and Martin from Crystal Heating & Cooling on site. They did an OUTSTANDING JOB ensuring the installation was done professionally and answered every question to my satisfaction. They laid drop cloths around all areas to eliminate any debris from coming in contact with the flooring, and did an excellent clean-up once the work was completed. They paid attention to the "details" on everything they did!... Great CREW and I would recommend Crystal Heating and Cooling to anyone in the St.Louis area requiring new A/C and/or Furnace installation. House is now COOL with the new high efficiency units running about half as much as my older unit that was replaced. GREAT JOB GUYS!

Crystal Heating and cooling have been my go to for my poor dying AC unit for the past five years and I finally took the leap to replace it and my heating system and I was not disappointed. They worked so hard and were so polite and easy to talk to. There were some other problems with the ductwork that I nor they were aware of until they started the work and they explained it perfectly and did a great job repairing it and making sure it was done right. They are the best and I would not recommend anyone else!

Hank Swallow

19:19 04 Sep 18

I couldn’t be happier with the job these boys performed. The installation looks and works awesome! After they finished, Cory went over the whole system with me and explained how to operate it and how to do the maintenance for it. Five stars! Well done!!

We have used Crystal Heating and Cooling for 9 years. They do a great job. The technicians are always curtious and prompt. There has been issues with scheduling but they have always made it right. We do the two appointments a year to keep our AC and heater in tip top shape. They have never had issues with my large dog or my very nosey three year old. If you want good people to do great service I recommend giving Crystal a call.

Will was very professional on the phone and in person. He came out on a Saturday and fixed our air conditioner in a timely manner. We appreciated his prompt response to our after-hours phone message and came out when he said he would. He seemed very knowledgeable and was polite and friendly. We definitely recommend him.

Laura Bergee

16:56 21 Sep 18

AC went out on Wednesday (late), thought I had it fixed early on Thursday. Late in day Thursday NOPE I didn't have it fixed! Called - they sent Will Lewis over asap and he had the system on its way to defrosting immediately. Answered all of my questions professionally and assured me he'd get another appointment for us the next morning - which he did, so that the system could be repaired. Thankful for their prompt and professional visit to our home.

I’ve had Crystal Heating and Cooling check my furnace and AC every 6 months for over 10 years. They do a great job, and the one time I had an issue, they readily fixed it and applied credit to my account.Will was the technician that came to check my furnace for the winter today. He was courteous, friendly, and thorough. He checked everything and kept me in the loop the whole time. Great service!

Angela

This is a great company. Will was our technician and he was friendly, knowledgeable, and did a thorough job. Highly recommend.

Will and Cary performed preventative maintenance service today. They were friendly, professional, polite, explained their findings, installed new filter and started humidifier for the system. They arrived at the time expected, and worked diligently while here. I have been a Crystal Heating and Cooling customer for years because of their customer service and quality techs. Today was no exception!

Don Coplin

21:34 13 Dec 18

I am glad Darren H came out today and found that the humidifier wasn’t draining properly. That wasn’t EVEN part of the "maintenance agreement". five/5 thumbs -up to Crystal Heating for having employees like Darren H working for them.

Brad Crady provided us with all the information we needed to make a choice of unit; he was so helpful, knowledgeable and most of all, a great person who was extremely patient with all of our questions.. Cory W and Kyle were the best! They were professional, efficient, tidy, and gave us all the instructions we needed to understand our system. I would highly recommend both the sales and technical team of Crystal. Their product and knowledge made this a wonderful experience. Thank you.

Dan Williams

15:15 18 Dec 18

I had Crystal Heating and Cooling install a second air conditioning unit in my house to take care of just the 2nd floor. From start to finish the entire experience was easy, professional and met my expectations. The estimator was professional, knowledgeable and there was no pressure. The estimate was very fair. A project manager came out later to inspect the house to configure the installation process and tell me about the installation plans. A couple days later the install team came out and I couldn't have been happier with the two guys that installed the system; courteous, professional, and hard working. Couldn't be happier with the entire experience. Overall rating: A+

Cary did a great job, he was friendly and professional. I asked him specifics about our system and he answered all my questions. We have a geothermal system, so I do ask a lot of questions sometimes. ?

Tony just left! Great guy! Very professional! Diagnosed quickly and was in and out in 30 minutes. Couldn’t be better in that aspect. Im just shocked in the parts markup. My only complaint. But they are in the same price range as competitors. So you can’t say much! HaOverall a great experience.

We love using Crystal Heating Cooling. They offer great prices for a yearly maintenance program and call with reminders. Darren H has been here a couple times and is very friendly and knowledgeable.

Trent Rickmar has rescued my home's ac/heating unit again. He's always on time, pleasant, timely and extremely knowledgeable about all that relates to heating and cooling. Today he quickly diagnosed our problem and promptly fixed promptly. Today, he took extra time (as he had in January 2019) to thoroughly explain all repairs, possible future problems, and general information about how my unit functions giving me peace of mind. I highly recommend Trent Rickmar of Crystal Heating and Cooling! Thank You Trent

We've used Crystal Heating & Cooling for over 20 years. We have found them to be honest about service that is needed. They communicate very well with us and are on time for service appointments. The few times we have had an immediate need for their service, they have been very responsive (here to do the work or check out the problem within 48 hours). We have had the pleasure of working with Gary, Darren, Ronnie and Will, and all have been excellent technicians! Highly recommend Crystal Heating & Cooling for your HVAC needs.

Cary was friendly and very courteous. He checked both our air conditioning unit and furnace thoroughly and worked while he answered a few questions. He discovered a problem with our air conditioner system and was able to remedy the problem by replacing the capacitor. He explained the problem as he changed the capacitor. We were satisfied with the job he performed and were thankful we had the service contract with Crystal Heating and Cooling, which helped with the labor and a percentage off for the required part. Thank you for the great service and great technician.

23:29 04 Sep 19

Our AC died on a 90+ day...of course. I called Crystal Heating and Cooling on a Tuesday morning and they had a technician out on Wednesday! Darren was friendly, professional and efficient. He even helped us save some money by explaining the maintenance plan. We have an old unit so it would have been easy for him to start pushing a new one on us. He didn't....he did explain that we need to prepare to replace it in the not too distant futur . He was in and out in less than 1.5 hours. We were very satisfied with our experience!

Lori Bunting

17:44 05 Sep 19

We were very satisfied with the friendly and efficient service from Crystal Heating and Cooling. We called on Tuesday and a technician was at our house on Wednesday! Darren was very helpful and explained everything to me. He even helped us save a little by buying a maintenance plan. We noticed good reviews, which is why we chose this company....and we were not disappointed.

Meg Caldwell

17:36 13 Sep 19

My dad used this company for A/C repair, and he said Cary J. did a great job. He wanted me to help him leave a review, which he never does, so I suppose that says quite a bit right there. Not only did he want me to leave a review, my dad repeatedly asked for help posting the review, so his experience really left an impression.

Quoc Luong

14:27 18 Oct 19

Requested Darren H for our yearly AC service maintenance cleaning. Always nice to see a familiar face becasue Crystal H&C have been servicing my and my mom's house for over a decade.

Darren did an excellent job assessing and correcting the situation in a timely manner. In discussing our thermostat, he suggested that we might like the Sensi, and we decided to have him install it. It's been a pleasant change, and we have thoroughly enjoyed its convenience. We have nothing but kudos for Darren and are impressed with his service.

Pat Mertens

17:24 09 Dec 19

The service Trent provided was quick and complete. He arrived shortly after calling and began right to work. He manner was pleasant and friendly. He completed his task by changing out the old filter with a new one, saving me time and effort to do so. I feel confident that our heating unit will provide good service through the winter months.

Porg McNuggets

17:10 20 Dec 19

They were very busy (totally understandable since it's winter), but made sure to get someone out first thing the next morning. Tony Z was a great tech and explained to me exactly what the problem was and what it would take to fix it. In only about an hour, he had me up and running again. Grateful for the courteous professionalism of Tony and the fact that I can feel my toes again! And while it's never fun to have unexpected expenses, the pricing was very reasonable for the service. I would recommend them to anyone needing work done.

Jeremy Lamb

19:35 14 Jan 20

Cary Jacobsgaard was my technician. He was very professional and informative. He inspected my furnace and diagnosed the problem. Cleaned the coils and advised me to upgrade to a better quality filter to prevent the same situation from happening. The service was top notch! I highly recommend Cary and Crystal Heating and Cooling! Thank you. Jeremy Lamb

Mary Turek Schanuel

21:26 14 Jan 20

The technician who came to our home was very professional and polite. Tony Z. answered all of my questions with patience and treated me with respect by not rushing through his answers.

This is why we have been with this company for so many years.Mary Oakville, MO

My furnace went out Thursday Feb. 13th at 3:30 p.m. and by 5:30 p.m. that day they had dispatched and repaired my heat pump unit. Kerry was an awesome guy and a great technician. I would highly recommend Crystal Heating and Cooling for any of your heating and cooling needs.

Brandon H

20:00 21 Feb 20

Let me start off by saying this company is the real deal! They're all about business and they make stuff happen! After a month of fussing with a home warranty company trying to get my furnace replaced I decided to ditch them completely and called Crystal Heating and Cooling. The estimator Nick showed up within an hour and gave me 3 very reasonable estimates on a furnace and AC unit combo. (exactly what I wanted) He gave me all the info I needed to make a good decision on a unit for the size of my house and then sent a crew the VERY NEXT DAY to have both installed. Estimated install time was 8 hours, both technicians worked without a break and installed both units in 4 hours in the dead of winter, even swept the floor up. Everyone I talked to was very friendly, knowledgeable, and trustworthy. Never condescending because you didn't know about something like a lot of people. VERY helpful and stand up company. Would recommend 110%!

Nate Govero

17:34 12 Feb 20

These guys were amazing. Very punctual with the time they stated they would arrive, super knowledgeable, and more than willing to answer any and all questions. They ensured all areas were clean and the job was done with precision.

See All Reviews

Unusual Noises. While low-level noises are normal for most air conditioning units, loud, sudden unusual noises can signal bigger problems with your unit. Sounds like rattling or buzzing could point to a loose part while whistling or a grinding noise can be a bit more serious. If you hear unusual noises, request a service call right away and don't' procrastinate. Chances are a regular tune-up that will help!
Blowing Warm Air. If you feel warm air blowing out of your AC unit, first check the thermostat and make sure its switch to cooling mode. If it is, make sure it's set it lower than the temperature of your home. Once you perform these basic checks, if your vents are still blowing warm air, it's likely you need freon is low or your compressor may be to blame.
Frequent Cycles. All healthy air conditioners should go through a routine cooling cycle. And while your AC unit will turn on more frequently on the hottest of St. Louis summer days, it should not constantly cycle on and off. If you notice frequent cycles, a quick air conditioning tune-up can most likely resolve frequent cycle issues.
High Humidity. Even in the stickiest of outdoor weather conditions, you should not experience high humidify indoors. A well-tuned AC unit should moderate humidity levels, automatically. If your unit isn't keeping moisture levels with a comfortable range for you, a simple re-calibration is in order. You may also consider a dehumidifier.
Insufficient Airflow. Nothing is worse than an A/C unit blowing warm air than poor airflow. If you're experiencing this in your home, chances are you have a clogged air filter, blockage preventing air from moving through your home's ductwork, or in worse cases, a broken motor.
Water Leaks. Air conditioners rely on refrigerant to cool homes. Sometimes units produce condensation as they operate so don't that concern you. What to look for in a water leak is signs of pooled water; an active leak. You'll know it when you see it.
Smelly Odors. Last but not least, nobody likes a bad odor, particularly unpleasant odors that are coming from an HVAC system. A quick diagnostics followed by a complete cleaning can most likely put an end to the embarrassing smell.

Have an air conditioning emergency in or around St. Louis? You can count on Crystal Heating & Cooling. Whether a home or business, we provide the fastest air conditioning repair in and around St. Louis. We get it, a broken A/C unit brings stress. We offer around the clock emergency air conditioning service you can count on.

Before calling take note of these important questions we'll be asking:

When did you first notice the problem?
Can you describe and explain the sound you hear?
What brand and model number is on your A/C unit?
When was the last time you replaced the batteries in your thermostat? (trust us, this can happen).
