There are several things that you can do about a heater blowing cold air, but if you keep running into problems then it might just be time to call in a heating repair company. If need be, here is a useful article on: HVAC installation cost, and how to get a fair price. How serious of an issue this is depends greatly on where you live. If you live in the north (Bozeman, MT, etc), then I'd recommend you have your furnace inspected annually to ensure that it is working properly. I'd also recommend that you install a backup means of heat...just in case. ASM has over 25 years of heating and air conditioning experience. If you have questions about a heater blowing cold air or any other HVAC related topic, try the ASM Air Conditioning and Heating Blog or if something your contractor is telling you seems expensive or doesn't sound quite right, consider using our Online Air Conditioning Consultation Service.

This job requires special tools and special training. If you lack either, you risk SERIOUS personal injury. Injury comes VERY EASILY! You need to address oil levels, proper and legal refrigerant recovery, system evacuation, and recharge. You were planning to also replace the receiver/dryer, correct? It also needs the oil in it measured and incorporated into the amount of oil (in %) that would need to be added. FAILURE to address these and other issues will guarantee premature system failure and likely compressor damage. Take this job to a qualified shop.
If your car is more than a few years old, it probably has a leak or a worn compressor. You can add too much freon for the system. It needs to be vacuumed down to a negative pressure before adding freon, and then checked for compressor function and leaks. You may need to take it in to a reputable shop.
My name is Ron,and I have one solution,Sounds like you need some freon added,if that doesn`t fix ya ,the ac compressor could be weak,or blockage in ac system,or vent door not opening,or opening slowly,and not all the way...hope this helps,firstname.lastname@example.org
change the cabin filter will get rid of the smell however for cold ac you will need to recharge the ac and have a black light test in 5 days or less after it was recharged. then they would spot for a leak in the ac system
