Frequently Asked Questions
How often should I service my HVAC system?
We recommend servicing your HVAC system at least once a year—ideally twice: once in the spring for your cooling system and once in the fall for your heater or furnace. Regular maintenance helps prevent breakdowns, improves energy efficiency, and extends the life of your unit.
Why Is My AC blowing warm air?
If your air conditioner is blowing warm air, it could be due to a number of issues including low refrigerant levels, a dirty air filter, a malfunctioning thermostat, or a failing compressor. Our technicians can quickly diagnose the issue and get your system running cool again.
How long does a typical HVAC System last?
Most modern HVAC systems last 10–15 years with proper maintenance. However, factors like usage, climate, and regular servicing can affect lifespan. If your system is over a decade old and showing signs of wear, it may be time to consider a replacement.
What size HVAC system do I need?
The right HVAC system size depends on several factors including square footage, ceiling height, insulation quality, and window exposure. Our team performs detailed load calculations to ensure your system is properly sized for efficient, even heating and cooling.

Yes! MC’s Heating and Air Conditioning provides emergency repair services to get your comfort back on track when your system fails unexpectedly. Call us anytime—we’re here when you need us most.
Can I improve indoor air quality with my HVAC system?
Absolutely. We offer several options to improve indoor air quality, including high-efficiency air filters, UV lights, humidifiers, and whole-home air purification systems. These upgrades help reduce allergens, dust, and airborne bacteria in your home.
Can I finance my HVAC System?
We offer flexible financing options for qualified homeowners, making it easier to invest in a new heating or cooling system without financial stress. Contact us to learn more about current financing promotions.
Can I reduce my energy bills with my HVAC system?
You can lower your energy bills by scheduling regular maintenance, sealing ductwork, upgrading to a programmable thermostat, and ensuring your home is properly insulated. Upgrading to a high-efficiency HVAC system can also significantly reduce energy consumption while improving comfort.
