Furnace Replacement

Sometimes a repair is not sufficient to fix your furnace. Sometimes a new furnace is the most cost-effective and energy-efficient way to go. We will always be honest with you about a possible furnace replacement. We value our time and your money––we don’t want to perform repairs or service on an appliance that is in need of replacement.

If you do need a furnace replacement, we know how overwhelming it can be. Here are some of the frequently asked questions about furnaces that we get from some of our Grain Valley, MO residents:

What Are The Different Types Of Furnaces?

Single Stage: A single-stage furnace has only one stage of operation. It can either be turned on or turned off.

Two Stage: A two-stage furnace has two settings––full and half speed. This is a more efficient way to heat and provides for better comfort, because it can move the air at a slower pace.

Variable Stage or Modulating: A variable-stage or modulating furnace modulates the speed and heat output based on the temperature outside and the desired comfort level. This furnace only works as much as you need it, making this type the most energy-efficient type of furnace.

What Is AFUE?

AFUE, or Annualized Fuel Utilization Efficiency, is a measure of furnace-heating efficiency. The higher the AFUE, the more efficient the furnace.

What Size Furnace Do I Need?

We can calculate the correct size furnace for your home. The number of BTUs, or British Thermal Units, needed to heat your home is dependent on a number of variables. Contrary to what you might think, a bigger furnace may not necessarily mean more heating power for your home. Call us at MD Repair, and we can set up an appointment to calculate the furnace size you might need.

“One of the old furnaces went out, in our Church, in Wellington. I called MD Repair, on Mondy morning, and Mike came on over. After checking the furnace, it was determined that a new one was needed. They brought the new furnace, the next morning, and got it installed.
MD Repair has also serviced my home Furnace/AC, for several years.
They are good, friendly people, and efficient. We have always been happy with their service.”

“I've been doing business with MD Repair for over 15 years. Mike installed a new hvac system for me and has maintained it ever since. Not only do they do a great job, but they are personable and professional.

My furnace quit last month and Mike was at my home immediately to check it. I had to purchase a new one and Mike's crew came out without delay to install it.

Thank you Mike, Mickie and team!”

Gas Furnace Replacement in Kansas City, KS, ST 66205

“I had to replace my full HVAC system and my Humidifier. MD Repair came very highly recommended by my private HVAC contractor. I called MD for an estimate. The owner himself showed up to look at my system, and provided provided me an estimate that was $5,000 less than the current on-going rates from the big companies, within 24 hours. The equipment He quoted me was higher grade than what I had.
MD's team (of 2) showed up at my house within 72 hours with all the new equipment needed and replaced my whole house system in less than 8 hours. They were professional, focused, have a great sense of urgency and timely. Their service is implacable. MD Repair, you will be the only recommendation I will give to my family and friends. Thank you for a great experience.”

Furnace Repair in Oak Grove, MO

My furnace went out on a Friday night and when I woke up the next morning it was 39 degrees in my house! I called MD and they answered even though they were closed. I was on the phone with them for 20 minutes and by the end of the conversation they had figured out what was wrong with my furnace. They got some information for me and they went above and beyond to find out I had a warranty. They ordered the part for me and it was delivered to their office late Monday afternoon when it was time for them to go home. Instead of doing that, they knew the next day was supposed to be the coldest in the last couple weeks, so they decided to go out to my house anyway and make sure they got my furnace fixed! When they showed up, they were very professional and kind. They went in and did the work quickly and the furnace was working as good as ever. 5 out of 5 and I will for sure be a repeat customer when the time comes! Highly recommend!

Furnace Repair in Overland Park, KS

Our furnace that was installed about 3 yrs ago by MD Repair went out yesterday during the middle of an ice storm. We called and reported the issue to Angela who was great to talk to. Bob called us back and helped us trouble shoot the problem to determine it was a blower fan malfunction. Unfortunately, they could not get out in the storm to fix it yesterday. Early today, Mike contacted us and was able to come out mid-morning. He quickly identified the problem, was able to go pick up the parts, and got the blower fan repaired. All was covered under the York 10 year parts and labor warranty at no charge to us.

We really appreciated the fast response and great service provided by MD Repair despite the bad weather. We were without heat for only about 24 hrs.

Thanks to Mike, Bob, and Angela for the great response!
5-star service!

My family would like to thank your company for taking the time to fix my daughter’s heat. I bought this home in July, not knowing the furnace didn’t work. This family has struggled for the last few months, we believe there is a Santa Clause. This never would have happened without your help. I have used your company several times and the guys there and the secretary are wonderful people. Thank you very much and God Bless your company.
