Heating & Cooling FAQ

What is the life expectancy of my HVAC system?

The average life expectancy of a residential HVAC system is 15–20 years.Central air conditioners typically last 15–20 years, gas furnaces 15–25 years, and heat pumps 10–15 years. Actual lifespan depends heavily on proper installation, regular maintenance, usage frequency, local climate, and equipment quality. Systems that receive annual professional tune-ups often reach or exceed the upper end of these ranges, while neglected units may fail sooner. When repair costs rise and efficiency drops significantly, replacement is usually the smarter long-term choice.

What brands do you install?

We install Rheem, Friedrich, and Bosch systems as a certified Rheem dealer and accredited Bosch contractor. We also service and can install most major brands of air conditioners, furnaces, and heat pumps. Our team matches the right equipment to your home’s needs, ensuring quality, efficiency, and long-term performance.

What is a heat pump?

A heat pump is an energy-efficient HVAC system that both heats and cools your home by moving heat rather than generating it. In summer, it extracts heat from indoor air and releases it outside (like an air conditioner). In winter, it reverses the process, pulling heat from outdoor air and transferring it inside. Heat pumps work well in moderate climates and can significantly lower energy bills compared to traditional furnaces and air conditioners.

Do I need HVAC maintenance?

Yes. Regular HVAC maintenance is essential. Annual tune-ups keep your system running efficiently, prevent unexpected breakdowns, extend equipment life, improve indoor air quality, and lower energy bills. Skipping maintenance often leads to higher repair costs and shorter system lifespan. Most manufacturers also require yearly service to keep warranties valid. Schedule professional maintenance once a year (ideally in spring for AC and fall for heating) to protect your investment and stay comfortable year-round.

    Customer Testimonials

    We had D&L out to the house on Thursday to try to come up with a solution for uneven heating and cooling on our 3 level home. They were extremely Thorough. Thank You!

    – T Williams, customer

    D&L has been a pleasure to work with. We recently had to have a coil replaced in our attic unit. D&L worked alongside our home warranty company. While we had some major communication issues with our warranty company, Lisa at D&L worked hard to speed up the process as much as she possibly could. Lisa was great at calling us back or keeping us informed during our claim process. Jeremy came to install our coil and he was professional, friendly and kept me informed on what steps he was taking throughout the installation. Highly recommend this company for customer service and quality of work.

    – E Vinay, customer

    Absolutely love D and L ! They treat you like family explained everything to me. They do free inspections to see what is going on. I have been absolutely happy with their service.

    – A Scott, customer

    Received a referral for D and L Mechanical Services from a friend, because my heat was not working. Technician was on time. Very friendly and provided me his card of the company. Before he even stepped in my home, he put on these blue booties.
