Selecting an HVAC Contractor
There are several factors to keep in mind when selecting and working with a heating and cooling (HVAC) contractor.
The following tips can help you make an educated decision and receive quality service:
- Ask for a certified HVAC technician. Keep in mind that not all states require certification.
- Your contractor should be licensed, well trained, and experienced to provide quality installations. Ask your contractor about his or her training, experience, and membership in contractor associations. Ask if he is insured and bonded.
- Good contractors own and use refrigerant recovery equipment and are certified to handle refrigerant in cooling systems. Ask for proof of certification if applicable to your state.
- Contractors should know how to properly size your home heating and cooling system (e.g., determine whether you need a two-ton or three-ton cooling system). Systems that have been sized properly to fit your home provide better humidity control, cycle on and off less frequently, and cost less than oversized systems.
- Your air conditioner or heat pump condenser should always match the indoor coil. Your contractor should replace both coils at the same time for maximum efficiency.
- Have your contractor select an install location that provides for ease of maintenance. Make sure the inside coil can be reached for cleaning. The air filter should also be easy to remove and should be cleaned or changed whenever it is dirty. (This can be monthly during peak season.
- Leave plenty of room for free air flow on all sides, and at least four feet at the top. Keep the area free of debris and shrubbery.
- Remember, the contractor who gives you the lowest bid may not be the best choice for you. Paying slightly more may get you better equipment and better service. Carefully evaluate a contractor’s proposal to ensure you get the equipment and service that best meets your needs.
- Ask about the warranty length, what it covers and if there are extended labor warranties available.

Your mobile home’s HVAC system plays a crucial role in keeping your living space comfortable year-round. Whether it’s the heat of summer or the chill of winter, you depend on your heating and cooling system to work efficiently. With proper HVAC Maintenance and care, you can extend the life of your HVAC System, prevent costly repairs, and improve energy efficiency. Regular Maintenance Is Key Change Air Filters Frequently One of the simplest yet most effective ways to extend your HVAC system’s life is to regularly replace or clean air filters. Dirty filters restrict airflow, making your system work harder and increasing energy costs. Check filters every 30–60 days and replace them as needed. Use high-quality filters that trap dust, pollen, and allergens. If you have pets or allergies, consider changing filters more often. Keep Your Outdoor Unit Clean Your HVAC condenser unit (located outside your home) can accumulate dirt, leaves, and debris, reducing efficiency and forcing the system to work harder. Clear away leaves, grass, and dirt from around the unit. Use a hose to rinse off dust buildup, but avoid high pressure. Keep at least two feet of clearance around the unit for proper airflow. Improve Airflow for Better Performance Check and Clean Vents and Ducts Blocked or dirty air vents and ducts can cause uneven heating and cooling throughout your home. Vacuum supply and return vents regularly to remove dust. Ensure furniture and curtains are not blocking airflow. If you notice weak airflow, consider a professional duct inspection and cleaning. Seal Air Leaks in Ductwork Leaky ductwork can waste energy and put unnecessary strain on your HVAC system. Inspect visible ductwork for gaps or holes. Use HVAC-approved tape to seal small leaks. If you suspect major leaks, schedule a professional ductwork inspection. Optimize Your Thermostat Settings Use a Programmable Thermostat Upgrading to a programmable or smart thermostat helps regulate temperatures efficiently and reduces wear and tear on your system. Set your thermostat to 78°F in summer and 68°F in winter for optimal efficiency. Reduce strain by raising or lowering the temperature when you’re away. Smart thermostats can adjust automatically based on your schedule. Avoid Overworking Your HVAC System Running your HVAC system at extreme temperatures can shorten its lifespan. Don’t set the AC too low in summer or the heat too high in winter. Use ceiling fans to help circulate air, reducing the load on your system. Keep blinds and curtains closed during hot summer days to block heat. Schedule Professional HVAC Maintenance Annual Inspections Keep Your System Running Smoothly Having a professional HVAC technician inspect your system at least once a year can prevent major breakdowns and extend its lifespan. HVAC technicians can detect minor issues before they become costly repairs. Professional maintenance includes cleaning coils, checking refrigerant levels, and inspecting electrical components. Regular tune-ups improve efficiency and overall system performance. Know When It’s Time for an Upgrade Even with the best maintenance, HVAC systems don’t last forever. If your unit is more than 10–15 years old, upgrading to a new energy-efficient model can save money and improve comfort. Older units often require frequent repairs and consume more energy. Newer models offer higher efficiency ratings, reducing utility bills. Upgrading to an ENERGY STAR® HVAC system can significantly lower energy consumption.
