Furnace installation in St. Charles and St. Louis, MO.

One of the benefits of working with Budget Heating, Cooling and Plumbing is knowing that you are getting the right size, type, and capacity of the unit for your home. Although gas and electric furnaces are the most common heating systems in St. Louis, our experienced heating and cooling experts work with many heating systems:

  • Electric Furnaces
  • Gas Furnaces
  • Heat Pumps
  • Boilers
  • Propane Heating Systems
  • Radiant Heating Systems
  • Forced Air Systems
  • Ductless Heating Systems


We Service & Install Furnaces

Having issues? Our heater and furnace repair techs will help diagnose your issues.

  • If your furnace won’t start or won’t stay on.
  • When your heater pilot light is out.
  • If your furnace is making strange noises.
  • The burner won’t light or stay lit.
  • The blower either doesn’t turn on, or it stays on continually.

Four Most Common Furnace Failures

CRACKED HEAT EXCHANGER – Heat exchangers are a critical part of your furnace and can crack over time. Once cracked, a heat exchanger can release harmful pollutants into your home.

AIR FILTER – All air flows through the air filter. A dirty filter can severely restrict air flow and cause the furnace to choke, overwork the system and eventually cause failure in the system.

GAS BURNERS – The burners in your gas furnace can get dirty causing a disruption in both gas and air flow. This can result in intermittent heat and the release of carbon monoxide.

FLAME SENSOR – Having a dirty flame sensor can cause your unit to shut down. Since it is the part that informs the rest of the unit if there is a flame present.

Always love using Budget. We used them in the past around Christmas time and they ensured we didn’t go without hot water. This week our Furnace went out ( it was 31 years old) and they were here the same day to assess what needed done. Then returned the next day to install our new Furnace. Everyone there is so easy to work with. They are professional, their techs are professional, knowledgeable and only have good things to say about the company they work for. We worked with Gabe and Mike. They were both excellent! Kaitlin in the office only made our experience even better! Thank you!

Contacted the office requesting a quote for a new Furnace and AC unit and they sent out Keith the following day! He was very kind and willing to answer all of our questions and even provided a quote the same day with a cash discount! It took about a week for our parts to come in, the installers arrived on time and were quick to get things rolling. They completed the job quickly and cleaned up after themselves when they were done. Would definitely recommend to anyone needing a new AC unit or furnace to use this company they were wonderful to work with!

- Bryant W.

Budget is the ONLY company that I trust for plumbing repairs and maintaining my heating/cooling systems. They have done work that others couldn't handle and at a decent price. I will continue to use them for whatever services they offer. I appreciate everything they have done for me so far.

- Meghan R.

We purchased our HVAC system from Budget in 2019 and have been very pleased with it overall, except recently the AC unit was making a strange noise. The unit sits on an elevated pad which I wanted it to be out on the ground at install but the tech did not have time to change that out. He told me that he would do it at a later date if it bothered us. Budget was quick to fulfill this request and Justin came out to put the unit on the ground. It looks so much better now, but the best part is it is now so quiet when it runs!  Beyond happy with the 5-star service the team at Budget provided. Thanks so much Cassidy and Justin!

Our Hot Water Heater just went out on us unexpectedly and Budget was able to come out the same day, assess everything and lock me down for a time, early next week. The customer service from Jennifer was above and beyond. She was so nice and helped my family. Isiah was very smart and knowledgeable and took the time to explain what was needed and the process. Would definitely use them again.

- Joseph C.

The technician showed up early and solved the issue right away. He was happy to address my questions and concerns regarding my aging HVAC. I was impressed with how knowledgeable he was. Per my request, he sent replacement estimates ranging from good to premier. This is the second time I’ve had great service from Budget.

- Amanda K.

I had a Water Heater installed today. Not only was it quality work, but the installers were professional and courteous. My house poses some unique problems as far as plumbing goes, but the installers handled it with ease. 10/10, will definitely use Budget again.

- Kelly G.

The Faucet in my condo was not working properly, the water flow on the hot water side was very small. Budget sent technician Tim to solve the problem and he replaced the Faucet in an amazingly short amount of time and patiently walked me through the Drainage System. He was highly skilled and efficient! Strongly recommend Budget!

- Tricia G.

We have had Budget out a couple times and they are always very professional, quick to come out once called and helpful! This past time it was Mike and he was great! Every time we need service on our HVAC we will continue to use them. Thank you for all you do!
