New and replacement AC systems have long lifespans and are vital to the overall comfort and indoor air quality of your home. This is why it is so important to choose an experienced and reputable contractor for AC installations.

From the heat of summer to the unexpected hot spells in between seasons, we ensure that you and your loved ones always have a refreshing retreat from the heat.

Why Hire a Professional AC Installer?

AC systems are vital to the overall comfort and indoor air quality of your home. But did you know? Almost half of all HVAC equipment in U.S. homes do not perform to their stated capacity and efficiency levels because they are incorrectly installed. That’s a lot of improper air conditioning installation jobs!

In fact, an improperly sized or installed air conditioner can reduce the equipment’s life expectancy, diminish efficiency, increase energy bills and prevent adequate cooling and dehumidification on the hottest of days. Our AC installers are comfort specialists and will assess your space, needs and budget. We’ll then provide you with appropriate installation options that are ideal for your home.

More Than Just an Installation

Choosing the right air conditioner is more than just picking a model with the right BTU rating. It’s about finding a system that fits your lifestyle, complements your home’s architecture, aligns with your eco-conscious values, and respects your budget. It’s about choosing a unit that will serve you reliably for years to come, offering you a cooling embrace whenever you need it.

Central Air Conditioner

Central air conditioners are the kings of cooling, capable of regulating the temperature of your entire home with effortless grace. They are, however, a complex piece of machinery, requiring expert installation to function at their best.

Ductless Mini-Splits

For homes without ductwork, or for those who prefer a more flexible, energy-efficient cooling solution, ductless mini-split systems are an excellent choice. Our techs are well-versed in these innovative systems, providing expert installation services to ensure optimal performance.

Signs You Need Professional AC Repairs

When your air conditioning system is working well, it’s easy to forget about it. However, it can’t last forever. Here are some signs that your current air conditioning system may be on its last legs and needs replacement.
Most air conditioning units have a lifespan of about 10-15 years. If your system is within this age range, it’s time to start considering a replacement, especially if you’re experiencing other issues.
If you’ve noticed a steady rise in your energy bills without a corresponding increase in usage, it could be a sign that your AC is losing efficiency and may need replacement.
If you find yourself frequently calling for repairs, it may be more cost-effective to replace the entire system. The cost of continual fixes can quickly add up to more than the price of a new unit.
Are some rooms in your home colder or warmer than others? This could be a sign that your AC is not distributing air evenly and might need replacement.
Unusual noises or smells coming from your air conditioning unit are often indicators of serious problems. If you’re hearing grinding or smelling a burning odor, call a professional right away.
If you’ve noticed a decrease in the system’s airflow or it takes longer than usual to cool down your home, your AC might be struggling to keep up with your cooling needs.
If your system uses R22 refrigerant, which is being phased out due to its environmental impact, consider replacing it. Newer models use more eco-friendly refrigerants.
A well-functioning AC unit should moderate humidity levels and filter dust from the air. If you notice increased humidity or dust, it may indicate that your AC is not working properly.
Remember, it’s always better to consult with a professional before deciding to replace your air conditioner. We can provide an accurate assessment of your system and help you find the best replacement if necessary.

This appointment was for an annual service on my new Furnace. Arrived on time, answered any question i had,and completed the service on the Furnace. Tyler also took the time to look at a problem toilet, gave me his thoughts on problem and then provided me a quot to fix. Maffei has generally always done a good job for me.

Tony, Maffei's Comfort Advisor met us at our cold church. He was so careful in checking things out, photographing our failed heating system. And he has gotten back to us in less than a week! Tony and Maffei concluded that Maffei doesn't do this type of project but Tony had several good referrals for us to services that do! Awesome! Thank you!
